     K-Seal Permanent Coolant Leak Repair is able to make a successful repair in the majority of applications, however in some cases the leak cannot be sealed. This is usually down to either the fact that the leak (or underlying cause) in the cooling system is simply too much for K-Seal to deal with, or a problem with the application or dispersal of the product. Following are some important points to check which may help to explain why K-Seal could not make a repair.

FAQ's - Troubleshooting Guide
 



1. The contents were not properly mixed and some residue remained in the bottle. It is essential that the entire contents of the bottle are added to the cooling system. If any residue remains in the bottle then add a little water, shake well and pour into the cooling system.

2. K-Seal was prevented from entering the cooling system. If you add K-Seal to the cooling system via the expansion/header tank it may take a little longer for the mixture to be drawn into the cooling system. This can depend on the rate at which coolant is being lost. A particular problem can occur with over pressurized cooling systems (head gasket failures) where the pressure is forcing coolant out of the overflow which can sometimes expel the K-Seal mixture before it has even had a chance to get in to the cooling system. In such cases you can either drain part or all of the cooling system first and then add K-Seal premixed with some water before topping up the coolant levels. This means that K-Seal has been delivered directly into the cooling system. It is also possible to remove a top hose and pour K-Seal directly into the hose.

If you have already added K-Seal to the expansion tank and the leak has not stopped then we recommend waiting at least a day or two to give K-Seal a chance to fully enter the cooling system.

3. K-Seal was prevented from flowing freely around the cooling system. If the cooling system is blocked, e.g. by an air lock, then K-Seal may be unable to reach the leak in order to make a repair.

4. The cooling system does not reach operating temperature. In order for K-Seal to have the best chance of making a repair the cooling system needs to get up to operating temperature to ensure that hot coolant is flowing around the entire system. If this does not occur e.g. due to a faulty thermostat, then K-Seal may not be able to function correctly.

IMPORTANT: Please use extreme caution when working on a hot cooling system as hot coolant and gases could cause injury. If in doubt please consult a qualified mechanic.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

      

 

 
 

                     

TESTIMONIALS

09/04/2009. Thanks what a life saver. Laura SW

03/02/2009: "HI. JUST DROPPING YOU A LINE TO SAY K-SEAL REALLY WORKS. I HAVE A 4.6 HSE RANGE ROVER AND IT WAS LOOSING WATER BUT I COULD NOT FIND WERE FROM. SO I BOUGHT A BOTTLE OF K-SEAL, PUT IT IN AND IT HAS NOT LOST ANY SINCE. THIS WAS IN MAY 2008. BRILLIANT STUFF." DON HUGHES, UK


13/01/2009: "I bought K-Seal the other day thinking it would not work - as a last resort after changing 2 headgaskets, never really given additives such as this much credit. I have a moderatly tuned Nissan 200sx s13, stuck the K-Seal in the rad,(only about half a bottle would go in), smoke stopped totally within 10 mins. I STILL can't belive how good this was! Totally astounded.
Thanks for making a Great Product and saving me hundreds of pounds! I promise I won't doubt K-Seal's abilities in the future!!!" John McNeil, UK
17/12/2008: "Hi guys. Just used your product on my 1800 diesel after the radiator blew a leak. After I tried 2 other inferior radiator sealants that did not work and I have to say well done. Within 5 mins all was well and the levels remain static. The k-seal was recommended by a soldier who says nearly every vehicle in a war zone carrys these as it's the only thing that will plug a bullet hole. Nevertheless well done and well played" Brian Reed, UK.
08/12/2008: "I purchased some of your K-Seal and it does exactly what it says on the bottle. The best thing since sliced bread." Nigel Webb, (Taxi Driver), UK
03/12/2008: "Well, what can I say about K-Seal. I was losing coolant from my car at a rate of approx 1 litre every two days in my 97 Golf and was dreading an expensive repair which I just couldn't afford after getting the alternator replaced a few weeks ago. I thought I'd identified a leak in one of the cooling pipes and thought that considering I thought I knew where fluid was escaping I might as well get it fixed properly and took it down the garage on Monday. The pipe was replaced and I went away happy and £50 lighter. Two hours later the coolant warning light was back on and the coolant level was well below minimum again. I'd seen K-Seal on eBay and read some good reviews and after leaving a few sheets of paper underneath the engine knew I was losing a lot of fluid from the radiator. I couldn't afford to get it repaired so bit the bullet and despite scepticism picked some up this morning. I've done 80 miles since then (first time I could go out of town without topping up the header tank) and have just checked and the coolant level has not changed even slghtly. I can't say at this stage whether the problem will recur but I'm going to sleep a lot better tonight. I would, and will, recommend K-Seal to anybody I come across with a coolant leak. Maybe it won't work for all but it looks like it's certainly worked for me! Thanks. Mark Smout, UK.
02/12/2008: "I sucessfully used your K-Seal product on my car earlier this year and so far 6000 miles and no problem with coolant loss." Phil Peacock, England.
01/12/2008: "Just to report 100% success,many thanks." Philip Constable, UK.
02/10/2008: "My ageing Rover 620 gave up the ghost 250 miles way from home. All the water had gone from the system. A mechanic told me it was time for me to buy a new car as the repair to the leaking head gasket was going to be over £500. A quick call to a mate at home, pointed me in the direction of K-Seal. Wow. I was able to get home, and was amazed that I hadn't lost any more fluid. Now I am home I need to replace the coolant as there is no longer any anti freeze in the system, But I am definately going to throw a bottle of K-seal in too. It really is a magic fluid." Rob Usher, UK.
28/08/08: "Having seen the results I am very impressed with this product. I think it would be advisable for any workshop to stock K-Seal, as more times than not, it can solve a problem quicker and at a smaller cost to the customer than a mechanical repair." Commercial Vehicle Workshop Magazine.
21/07/08: "My Discovery TD5 overheated and started using water by the gallon. Garage tested the radiator and there were exhaust fumes present so they replaced the Head Gasket costing £350. 2 days later the same problem, every 20 miles the radiator overheated and used all the water. Back to garage and was quoted £1200 for a new head, they thought it was porous or warped. I went home and looked up my options on the internet and found K Seal, ordered it straight away, even though it was the least expensive and the competition all said they were the best. When it arrived, poured it into radiator, topped up radiator and let car run for 10 minutes. 1500 miles later and it has only used a cup full of water and never over heated or missed a beat since. What a product, what a money saver, what a life saver, Thanks." Kenny Fraser, Scotland.
21/07/2008: "Just to let you know my SAAB had been leaking water since I have owned it even after a heater matrix change and a core plug change costing several hundred pounds. 1 small bottle of K seal and all is well several months later and the SAAB now holds water at long last!! Add me to the list of satisfied customers. Regards Mike Strutt, Milton Keynes.
03/07/2008: "Hi, i recently used Kalimex to sort a problematic head-gasket on a Land-Rover Freelander.. while on holiday in the Lake District and as usual i said i would sort it out properly when we got home to to Cornwall, 350 miles away... but its still ok so i'll leave well alone... and its saved me a fortune...... But to add to that , i recently MOT'd my daughters Renault Megane, and it failed miserably on the emissions test.... so instead of replacing the lambda sensor and catalytic converter, i tried your new product..CATACLEAN, now this stuff is a miracle worker, when i took it back for re-test, it PASSED with flying colours... the MOT tester asked what i'd done to get the emissions so low... then i told him about CATACLEAN......
And to top this off, a friend from Worcestershire phoned me last week to say his Discovery-TDi had failed MOT on emissions, he couldn't find CATACLEAN anywhere in Kidderminster, Worcestershire... so i put a bottle in the post,, voila, his 4x4 passed the MOT... he was as amazed as me, as most people are sceptical about these miracle fluids in bottles.... but i'm convinced 100%." STEPHEN HAYWOOD, CORNWALL.
19/06/2008: "We were skeptical of any product that says it is a permanent fix, but we were so impressed by K-Seal that we ordered a second bottle for our son. I would not be afraid to use this product in any engine. I was a mechanic for 20 years and never believed in 'Mechanic In A Can' until K-Seal. Thanks." Jack Smith, Texas.
28/05/2008: "I recently used K-Seal on my '98 Subaru legacy 2.5 4cam with a manual box. I was losing a bit of water either through one of the head gaskets or a tiny crack, I am not sure which. I purchased some K-Seal and added it to my coolant. The results where nearly instant and really astonishing. This was great news for me as the engine had only clocked about 15K. It is a really big job to take the heads off a Subaru as I am sure you know and you have saved me hours of work and or hundreds of pounds. I am very pleased and will tell all my friends about this. People can be very sceptical about all aspects of liquid engineering, but I am sure if they used your products they would quickly change their minds." James Green, Lincolnshire.
19/05/2008: "Life Saving Products. I was 200 miles from home when my radiator started leaking. I purchased a bottle of K-SEAL and within minutes was on my way. That was 4 weeks ago and I have not had to top up since. THANK YOU." David Bain.

22/04/2008: "I would like to inform you of the success I have had with your K-Seal product. I have a Rover 75 2.5 V6 and some weeks back it developed overheating and coolant loss problems, I took the car to a garage and they did some diagnostic tests and told me the bad news that the head gasket had gone and quoted me almost £1,000 to fix it! Having picked my jaw up from the floor I searched the internet for other solutions and discovered K-Seal. I followed the instructions, added the magic potion to the cooling system and took the car for a 15 mile run just make sure I had given the stuff every chance and I admit, I was doubtful at the outset, but I'm pleased to say it fixed it! I have now done over 2,000 miles in the Rover, some motorway, some town and traffic queues and it runs fine. RESULT!
Many thanks, Great Product. Regards, Neil Hardy."

17/04/2008: "I spoke to MD of K-Seal in the UK about my problem with a Range Rover TD6 2003, leaking coolant at a litre a month. He said K-Seal would fix it, I bought some that day, put it in the header tank and lost any coolant since and that was over a month ago. What a fantastic product and what a huge saving compared to going to the main dealer for diagnostics. THANK YOU VERY MUCH." James Stuart, England

31/03/2008: "This is the third time that I purchased this product from you because your product is unbeatable when it comes to cooling system repair" C. Mercieca, Malta.

04/02/2008: "Thanks for K-Seal, it's a great product"
Stuart Conway, UK.

01/02/2008: "I didn`t think miracles happend but thanks to purchasing your K-Seal it has. It helped my dad save a fortune repairing his leaking head gasket on his Rover 416 K6 engine. Unbelievable cheers thanks for producing a product that realy works." Steven Thomas, UK.

18/11/2007: "Dear sir. I would like to take this opportunity to congratulate you on your excellent product. The vehicle I drive is a Mitsubishi Pajero which recently had a radiator fail. This was not a problem as the radiator was replaced. Due to the colder weather being forcast I decided to install anti-freeze at the % stated by the manufacturer. This resulted in the vehicle making a considerable amount of white smoke, not ideal. This white smoke was the anti-freeze being sucked into one or more of the cylinders, not being fully combusted. The on going outcome, the nearest motor factors, Whiston Motor Factores, stated that your product was one if not the best! I cannot state how high a spec has been achieved by your product." Mr G Birch, UK.

30/10/2007: "I got some K-Seal from our local garage repair shop for leaky head gasket and it's working great." Dave, UK.

13/09/2007: "Just a thankyou - purchased from Finishline, and so far so good ! Seems to have done the job (rare nowadays) ...in since 06/09/07 with no symptoms of failure to date." Ged, Doncaster, UK.

31/08/2007: "I own a Vauxhall VX220 (A British hand built sports car built beside the Lotus Elise/Exige). With a 2.2l GM Ecotec engine designed by Lotus and built primarily in the USA. The engine recently suffered from a cracked cylinder head above the spark plugs whilst on a routine service. I originally bought K-Seal as a 'get the car home' cure, however im delighted to say that over 1000 miles, driving how the car was made to be driven (very hard), K-Seal has held all that i've thrown at it!" Edward Butler, England.

27/04/2007: "Kalimex K-Seal I'm Impressed ! Now as you guy know I have been around the block a few times, not that I am cynical but it takes a lot to impress me, K-Seal has. My mate bought a Rover 800 2.5 KV6 at auction ---it ran great for the first two weeks then the rad core disintegrated and he truly cooked the engine --- not a good idea in the early version of the KV6. New radiator fitted and he still had a case of slowly disappearing coolant and signs of water in the oil and oil in the water -- As replacing a head gasket is no joke on the KV6 in the 800 so in went a container of K-seal. The result was amazing --- no coolant loss and even more amazing no more emulsion in the oil side. K-seal is completely different from Radweld or Barrs Leaks type products neither of which I would use on a modern engine -- Back in the stoneage Radweld was fine for emergency repairs on radiator leaks on older cars provided you removed the thermostat first, while Barrs Leaks had so many solids in it blocked the raddiator cores up." Posted on the locostbuilders.co.uk forum.

26/04/2007: Dear Sir/Madam. After being quoted £60 for a new radiator, giving K-Seal a try was an easy option. So I tryed it on my J-Reg Transit 2.5DI and hyes! It seems to have worked. Thank you, Steve Cummings, Suffolk.

31/03/2007: hello there i have used your product and i really cant sing your praises enough you have made me the happiest bloke around i can now ride my bike [zzr1100] again you have saved me the price of a new engine.. if at any time you want to use me and my bike in a promo you are totally welcome.. once again thank you yours joe jacobs.

30/03/2007: Hi there, I have just used your K-Seal product in my Rover 216 with a K-Series engine that had a leaking head gasket (A common problem on these engines) so far so good, no more coolant loss into the sump ! Thanks. Rob Williams, Flintshire

18/02/2007: Hi, I have used K-Seal with great effect on my Vito van. Leak stopped in 3 minutes although you know that already :-) Andy.

11/02/2007: Hi. Just used K-Seal on a 1998 Escort 16V Zetec with badly leaking water pump,did,nt expect it to work but it has and will allow me to run without changing pump at this stage which involves considerable work because timing belt has to come off. Great Product. Dave White, Newark.

06/01/2007: Thanks for your fast dispatch, used the product ...so far so good ....... mazda 626 diesel estate heater matrix with severe leak........really impressed and will be recommending without doubt..
regards Steve, Staffordshire.

20/11/2006: My 1999 Escort recently had a leaking heater matrix which the AA repaired using K-Seal. Mr C.S. Wright.

06/11/2006: i purchased your k-seal as had a leak in my cooling system right after where a hose connects brillant stuff. i own a renault laguana. ian woodley colchester.

08/10/2006: Hi, I tried K-Seal on a water leak on my Fiesta 1.25 Zetec 2000 model year. The reason for this, was that because of Air Con pipes, I could not see where the water was coming from. I suspected that it was the water pump. I used K-Seal on 28th Sept & to date have no more water leak. Thanks for a product that does what it says. Tony Kula, Stafford.

03/10/2006: 16th September 2006. Added K-SEAL to a leaking 10 year old radiator on a Citroen Xantia 1.8 16v. Took car for a run along the local by-pass to get coolant up to operating temperature. Checked later and coolant leak stopped. Interestingly, on 29th September had cam belt changed and at same time took opportunity to have the water pump changed which required emptying of the coolant in the radiator and subsequent refilling with fresh anti-freeze. The K-SEAL fix still appears to be working as the radiator is still not leaking. Stephen J Bradley, Crewe.

19/09/2006: Posted on Lexus Soarer Owners Club forum lexusclub.co.uk "the stuff really works! My old man used this on a diesel shogun with a cracked block and it is still running over 18 months later. My 325 beemer had the headgasket go, poured this stuff in & 3 minutes later it was sorted, duly continued to thrash the thing off the limiter on a daily/ hourly basis and it never complained."

13/09/2006: Dear Sir/Madam.
We recently used K-Seal on a 53 plate BMW 525 diesel with good results.
Regards, Paul Lanyon, Heritage Coach Works.

13/09/2006: I USED K SEAL IN A PEUGOUT 306 DIESEL AND IT WORKED!I USED IT ON THE M53 MOTORWAY JUCT 9.ON THE 11/9/06. JOHN.

28/08/2006: have used K-Seal several times and found it to be the best coolant seal on the market after using a multitude of products over the many years in the motor industry.Used on leaking core plugs successfully and also cast in steel pipe fittings where the fittings had rusted through.
It goes without saying that I am very impressed with K-Seal and curious to see whether other Kalimex products are as good. Thank You. louis grainger,
vale garage services, wales

25/08/2006: used this in my jeep cherokee 2.5 TD to seal up heater radiator did exactly what it said on the tin will consider using at work on fleet of erf lorries Tony Meens, welchs transport, uk

25/08/2006: I purchased peugeot 306 with head away on ebay and then the K seal and because it worked I bought 2 bottles for my toyota celica and the head gasket from trechii can wait to be fitted. jim bett, Scotland.

17/08/2006: used k seal on my gl1100 motor bike and it was 1st class thank you m dray, nr truro cornwall

08/2006: Dear Sir or Madam. I have a Chrysler PT Cruiser which is not very old but out of warranty it developed a bad leak in the coolant radiator between the plastic header and alloy core. No way I'm told to repair it but to replace with costly new one. I purchased a bottle of K-Seal, poured it in cooling system and like magic after first run completely sealed and water tight and remained so. Mr G Swift, Barnsley.

01/08/2006: Dear Sir or Madam. I bought Kalimex to fix my heater matrix which had a bad leak. It stopped within two minutes which was four weeks ago. I've found the Kalimex very good as my heater matrix has remained bone dry. Job was a 1994 [Peugeot] 405 diesel. Cost at the garage to fix it over £200, Kalimex price £10.95. Thanking you very much. Mr Tabern, Lancashire.

01/07/2006: Quote from vauxhallownersnetwork.co.uk "Emailled the company lastnight & got a reply this morning. The only local supplier is in South Shields, so I got a mate to drive me over today & get some. £9.38 (incl vat). Got home, stuck it straight in, bump started the car & went for a drive, as directed to by the bottle. 5 minutes later... I no longer have ANY white smoke coming out of the back of the car, & no loss of water. The stuff is amazing. From my experience so far, I'd highly reccommend it. I went out this afternoon, 25 degrees c, & stuck in rush hour traffic on the A1. Never did more than 15mph for around 20 minutes. The car reached it's usual temperature, & stayed there. As soon as the traffic cleared, got up to 70mph, & the temp dropped back to just over 90. If the stuff was going to goose my radiator, or just didn't even work, that test would have shown it's faults, I'm sure, but no problems whatsoever. K-Seal: Does what it says on the blue plastic bottle

19/05/2006: what a great product used some sh*t in my time but this done what it says on the bottle \\\\we were in the middle of nowere in a 80 silver shadow rolls with a split radd got a bottle kalimex from a farmer of all people who said he bets it dont work bit like the old rad weld stuff well i tell you we were both gob smacked when the radd held water well done and thanks from me and a suprised farmer--\\\\yours graham (London)

15/05/2006 Hi. I used K-Seal on the water system of my Rover 400 series, as I had a water pump link, and was loosing about 3 ltrs of water every short journey.
Put K-Seal in the overflow tank as directed, and as I let the engine run, I could see the water leak underneath dissappear, it's great thanks.
Sam Malone, Kent

12/05/2006: Just like to tell you how good your products are. I had a leak somwhere on the engine. I had a 75 mile trip to get home. I went to a spares whop and was told to use this...I was going to buy radseal but the man in the shop said try this. As i am not working at preasent i have not a lot of money so i took his advice. what a good move no more problems.the car is a ford focus thank you . Danny Wilson, Essex.

21/03/2006: I used k-seal on March 20th at Lancashire County Council workshop, Whalley near Blackburn. K-seal was used to seal a leaking head gasket in a Daewoo matiz engine and it has worked successfully. Nigel Winder, Lancashire.

29/11/2005 Hi Mike. Thanks for delivering the above so promptly, we received it on Saturdaymorning. We used it to repair a leak in the head gasket on our Rover 400 1999car. My husband is very pleased with the result as it had sealed it in amatter of minutes, and he has recommended it to his motor mechanic friend whowas unaware of it when he spoke to him late last week.I would like you to enter us into the monthly draw quoting 'IDEA 5501'.Thanks again Regards Brenda

13/11/2005 About 6 weeks ago my 1935 pre-series Morris Eight developed a small leak in its cooling system. I discovered that there was a leak around one of the front core plugs. The front core plug is not easy to get at as there in not much room between the engine and the radiator, so I looked for a solution that did not involve removing the front of the car, or the engine. I knew products like K-Seal existed but I coudn't remember the names of any of them. I searched the internet for engine sealers and I found a company advertising bottles of K-Seal that I could order on line. I placed an order and a few days later, a small package arrived in the post containing the K-Seal. I poured the contents of the bottle into the header tank and the leak appeared to stop almost immediately. That was about three weeks ago, and I haven't had a problem since then, thanks to K-Seal. I have attached a file containing a picture of my car so that you know what it looks like. If I come acroos somebody else with a similar problem I will definitely recommend the use of K-Seal. Thanks. Adrian Mitchell

06/11/2005 Dear Sir/Madam,Thankyou reference IDEA5501Your product was amazing. I used it to repair a crack to my cylinder head on my nissan cargo import. I had been quoted £650 for head repair and gasket. I used this product and it did the job curing all the leaks. I am totally in your debt and would recommend your product to my friend’s.Mel ParkesLincs.

22/08/2005 Mark Sallows (Carsem Europe)(Land Rover Discovery 2 (2000 year model) with a leak in the heater matrix). Hi Mike,Just a quick mail to say that the 'K-Seal' did it's job fantastically, I cleaned out the system, filled half full, put the 'K-Seal' in and topped up and bingo.....no wet feet and no leaks in the engine bay..........I have been promoting your product to everyone I talk to and sold about half a dozen bottles for you......I need your advise again though. A colleague of mine has a Mazda 626 2.0L with a small blown head gasket (still driveable just..), will the 'K-Seal' be up to the job of fixing the leak in the gasket or should he use 'Seal-Up??Please advise so he can buy the right product of yours and get his car backon the road Cheers Mark

01/07/2005: Enquiry From : Andy Lees, Huddersfield,West yorkshire,. I have just used K-seal in my 1995 Omega to seal the head gasket and it worked a treat what an excellent product u\'ve saved me a small fortune. Thank you.

Enquiry From : Barry Dowler : Hi, wrote to you earlier, just purchased your product K-seal and it has cured a significant water leak, well chuffed!!! I will be recommending your product to all my 4x4 offroad pals.... Thanks Barry

11/04/2005Enquiry From : Rob Gilfoyle Recently purchased K-Seal for my Rover 25. Recommended to me by my uncle who is a Motor engineer in Derby. Car symptoms were misfiring from cold start, excessive steam/smoke from exhaust and frequent top ups of water expansion tank. A local garage informed me I needed a new headgasket so tried uncle's advice first before forking out for an expensive repair (approx £350). K-Seal so far has worked wonders, all the above symptoms have just about subsided and the car runs a lot better overall. Many thanks.
