Thanks for the fast delivery on my Kseal order. I have to confess that I ordered it in hope rather than expectation to fix a head gasket water leak on my Rover 25. Very much to my surprise it has worked just fine - just like it says on your website! Chris Macauly

I have an Isuzu Trooper Citation 3.2 litre V6 24 valve, I started to get head gasket problems etc so I popped in a tub of K Seal the truck has been fine with no further problems.Thank you very much it has saved me £1500!! Regards Steve Knights

04/02/07 Had a fault diagnosed by RAC as water pump, have been running car with fan on to keep from boiling up for about 6months. . Put Kseal in , 5 minutes later, switched fan off NO Problem!! Hammered it round for 30 miles, all ok, no overheating. Great, Jeff.

27/01/07 Seems to do exactly what it says, its given my old astra a new lease of life after a head gasket water problem! All in less than 24 hours of ordering from ksealit. From J . Sleigh, Edinburgh.


23/01/07 hi,having been ripped off 1100 pounds for a head and gasket replacement and waiting 7 weeks for the privalage i was bit disapointed when the pipe that had burst causing the problem hadent been replaced and sprang another leak.replaced the pipe myself and added a bottle of k-seal just to be on the safe side sevaral thousand miles later all is well and i know not to take my car back to a certain saab macanic in cardiff.ill add a bottle to all my cars from now on! Nick.

18/01/07 I put K seal in my coolant to fix a fairly bad leak that I suspect was the head gasket.Absolutely Brilliant it stopped the leak! Norman

12/01/07 Fantastic product, cured my overheating problem with my aging Toyota Hi-Lux Surf within minutes. Can’t thank you enough but you really need to tell the world about this one!!! Tom

31/12/06 I am amazed!!! I bought a Rover 75 2.5 V6 just before Christmas. The previous owner had recently spent £2500 with the main dealership in Manchester for a complete engine overhaul to cure a water leak, and when he found on its return that it still used water at the rate of about a litre per 28 miles he found the dealer unwilling/unable to trace the problem. He sold the car for £3000 at auction just to rid himself of the hassle and expense. On purchasing the car I had it checked over but no one could find the source of the water leak. A friend in the motor trade suggested I try K seal, and I put a bottle full into the system, not expecting much by way of success, but hey - presto, it has completely stopped the leak, and has been water tight for over 500 miles. I keep checking the levels just in case, but am now confident that it has worked perfectly. The moral of the tale is: sometimes a £11 bottle of maintenace is more effective than £2500 spent on repairs at a main dealership. Well done! I shall always reccommend K Seal.Simon, Lymm


30/12/06 Last week my heater matrix on the old (high mileage, K reg) Peugeot 306 started leaking water and steam everywhere. My footwell was soaked and my windows were steamed up more than the local swimming pool. I was gutted when I got a £180 quote for a replacement from my local mechanic. I tried the usual brands available in my local autofactors, and they didn’t work at all. Then I came across K seal advertised, and I thought “it can’t possibly be as good as the website says”. How wrong I was, within minutes of adding to my radiator, the leak stopped and my car’s now warm and dry again. Brilliant! Keep up the good work, all my friends and family will be using K seal very soon. Kindest regards, Richard

30/12/06 THIS WAS FOUND ON A VOLVO FORUM: I added k-seal today and it looks like it has sealed the leak!! I have used Radweld previously in some of my older cars without much success so I avoided this (hey I know it works for some people though)It said it should seal any leak not greater than 0.75mm wide in 1-3 minutes after starting the engine. I was losing in the region of 200-250mls of coolant everyday. I hope this doesn't sound silly, but because I could physically see the leak under the front manifold, I literally watched the leak stop before my very eyes!!!Well it worked and I am happy, at least for the time being. I've given the brick a good run up and down the motorway and she's cooled down, still no leak. Hope it holds. My only regret is that I have a sparkling clean water pump which looks look silver plated in those murky depths.Here's the linky to K-seal: http://www.ksealit.com/ BIG RECOMMENDATION FROM ME!


15/12/06 Thanks for your E:Mail about the MPG CAPS, from your records you will know that I have only recently purchased some, and my 1983 Land Rover is only on the first 3 caps, so my feedback is not sound or safe just yet BUT I have noticed that she is running smoother, and the deposit in the tail pipe is a lighter colour evidence to me that it is running cleaner, I am now retired but I was trained as an engineer and spent time in R.E.M.E working on Land Rovers and other light vehicles, although I went on to QA management for Multinational companies my engineering skills are still there, the Land Rover was bought 18 years ago and rebuilt by myself, and is maintained to military spec, on the emission test she flies through running on Shell Optimax and Castrol lead replacement, when you asked what did I want as a gift I thought a few caps would be ideal because I think there is something there, but it does need longer to test for me to give a valid response, all I can say is there is an apparent difference after 3caps, but for the winter time a Land Rover is thirsty due to standing idle with the engine running to get warm and going no-where, I will write again later when I can get a fuller picture. Regards and Happy Holiday Roger.


13/12/06 Great stuff it sealed my jeep radiator in less than five minutes, Robin


11/12/06 READ ALL OF THIS: FIRST EMAIL:Unfortunately K-seal hasn't helped my minor head gasket leak. As I informed you oil was passing into the coolant not the reverse. However now I have both oil in my water and moisture in my rocker cover casing indicating total failure. I thought that for £10 K-seal was a possible solution, it wasn't!


2ndEMAIL:
After skimming off the K-seal left in the radiator,guess what there is NO more Oil Coming through!!! So K-seal must of sealed it!! I will put this on forum when I get the chance. I am extremely happy. Just to let you know the K-seal must of taken about about a week or so to stem the flow of oil into the coolant.But this has definitely happened! I am very pleased to be proved Wrong!! The moisture in my rocker cover case must of been just damp on a cold morning as that's ok now too!! Kind regards and many thanks!!Guy


06/12/06 Many thanks for your excellent product. I was a bit wary about putting it in my radiator system but my fears where unfounded - the leak stopped within two minutes and appears to be completely leaktight. Have now topped up with antifreeze and am ready to go.I was travelling back from a visit to the North East and my overheat warning light came on. (Toyota Yaris) I pulled in but as it was raining cats and dogs, I couldn't really see anything under the bonnet.I called the RAC and the patrolman topped up the system and discovered that I'd sprung a leak in my radiator. He followed me home to ensure I was OK and I phoned the Toyota garage to book the car in for a new radiator. (No need to tell you how much that was going to cost!) You product arrived on Thursday and I applied it immediately. The good news was that I cancelled the garage appointment and have had no problems since.Regards Edward.

01/12/06 This product simply works! I fully recommend it! Michael


29/11/06 Thought I'd better drop you a line. The ex has admitted to me that she has not added ANY water to the cooling system since I added the K-Seal 10 days ago. Before she was using approximately 1-1.5 litre every 2 days for local journeys (15-ish miles a day). The garage mechanic still insists that it will not be a permanent repair and is still pestering her for a Head gasket change or P/X. I can say "no" because it is MY car not hers!! She also tells me that the mpg and power also seem to have improved slightly and the only thing I can say is what an amazing product, it really does what it says on the tin!! Please feel free to use this in any testimonials.Regards SHAUN



20/10/2006 HI, I would just like to tell you my little tale of woe! My Rover 200 started to lose water, i thought had a leak somewhere but not being mechanically minded I didnt think much of it. Then disaster struck and blue and white smoke started pouring out of my exhaust. Even though I know very little about cars, I knew that this was a very bad sign. I checked the symptoms on the internet and happened upon the K-Seal site. Knowing that my father had recently paid out £703 to have his head gasket replaced I thought I would give it a try - what did I have to lose? The little bottle of K-Seal turned up within 48 hours of ordering it and I went straight out and (following the instructions diligently) popped it into my expansion tank. It took a while, and the smoke was horrendous - even in the dark! But eventually the smoke stopped! It took about 8 minutes from reaching running temperature - such a short period if time and such little effort!! I have been driving it -very gently- to work and back every day since without a problem. I never thought it would work but it did!! I am over the moon!! K-Seal has just saved me over £700!!! Unbelievable! I will certainly recommend it to anyone and I will shortly be purchasing another bottle to pop in just to be on the safe side!!!! THANK YOU!! Sarah Plymouth.



19/10/2006 Hi, I am amazed I am writing this note!. I bought your product after severely cooking my Volvo V70, the bottom hose clip corroded and blew the bottom hose off. Warning messages came up on the dash board to stop the car (blokes take no notice of warnings) and after about 2 miles the engine started to pink. Un surprisingly for the next couple of weeks, the car used about a pint of water per 20 miles. I found your site on the web and thought I would try K Seal before I went looking for a replacement engine. After half draining the coolant and pouring the magic potion into the top rad hose, put it back together, toped up, and have never had to take the cap off again in two months! I have learnt two things...One, Some times things do what sellers claim...Two when your Volvo tells you to do something, DO IT.Thanks, Steve. Suffolk.



18/10/2006 Received my order promptly, I have followed the instructions and the very small water leak has stopped almost immediately. Just one small question: If I drain the system for the purpose of renewing the anti-freeze will the original seal to the water leak still hold good? Thanks a lot for this great product.David.

16/10/2006 Dear Sirs. I never believed it could work but after the cheapest quote to fix the head gasket on my Ford Probe came in at £500 I had nothing to lose. I followed the instructions and after 15 mins there was no water at all coming from my exhaust.I replaced the spark plugs and now my car runs like new.WHAT A PRODUCT!!!!!!!Thanktou.Barry



14/10/06 K-Seal fixed an Estima Head, yes, completely cured! Got to the hydrauliced engine stage, took the 4th glow plug out and blew the water out, started her, added a bottle of K-Seal once she was warm - straight into the header, and haven't looked back since. No smoke, no missing, no water loss and starts first turn of the key. Thanks guys, you saved me an £1800 bill. I was a complete sceptic. It has now been 6 months and my Estima is still running like new. Clint. (Yes, it is my real name!)



12/10/06 Hi There, Got my K-Seal gasket repair and was so disapointed wuth the size but have just tried this by filling the car up with water and watching it leak to half full, got it up to tempreture, added your stuff, waited a minute or so, replaced the radiator cap and went for a drive for 5 minutes at between 30 and 55 mph and I couldn't get the temp above a third and it only lost 250ml of water, unbeleivable!!!! I am just about to take it for a longer run but first impressions are that it works, thanks for saving me £500+VAT. (P.S. it was head gasket and cam seal that was leaking). Dave



10/09/2006 I'd be more than happy to recommend you to my friends. The K-seal has saved us a fortune! Kind regards, Lisa



09/09/2006 Hi, thought I'd just say thanks for your help and it looks like the K-seal has done the trick! Woo Hoo result!! Thanks so much, Lita.



07/09/2006 Great cheers IT BLOODY WORKS! cured my cylinder head leak brill :-)



06/09/2006 Hi, Just a word to inform you of my findings after using Kseal in my car. Symptoms prior to Kseal: Over 18 months, water loss became greater,approx 1/2litre in three days, upper and lower hoses under very high pressure,( could not be squeezed),in the last 2 months starting(hot or cold) became iffy, would start and take upto 20-30 seconds to run smooth. Engine would miss, not badly but I could feel it when warmed up. After putting Kseal in radiator: Within 5 minutes engine miss dissappeared. Starts 1st time all the time. Water loss reduced dramatically, too early to be entirely satisfied but will wait for a few weeks and let you know.Cheers,Eddie.Belfast.
P.s. I have just this morning put a message on the UK Honda car club, re your Kseal and how good it was!!!



26/08/06: I did visit your site and was about to order K-seal when my friend
who is a mechanic, discovered that the thermostat was actually the problem, it had jammed in the close position. I would like to thank you for taking the time to send an email enquiring about my problem, if in the future my friends or I need K-seal we will definately buy your product.



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

01/08/2006: Dear Sir or Madam. I bought K-seal to fix my heater matrix which had a bad leak. It stopped within two minutes which was four weeks ago. I've found the K-seal 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 your price £9.99, What a BARGAIN!



08/07/2006: Bought a bottle of k-seal it unfortunately did not fix my headgasket problem, which was ok because at least I knew it was a major mechanical repair that was needed, on investigation It was a very large crack in the head you didn't stand a chance! I would of hated to spend the £400 it cost me to find it was another fault, cheep diagnosis tool a compression test would have cost me twice that!.Your telephone call and help was much appreciated, Thankyou Ksealit.com. Mr P. Scott, Cambridge.



9/05/2006: 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 a k-seal 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 kseal on March 20th at Lancashire County Council workshop, Whalley near Blackburn. kseal 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, Thanks for delivering the above so promptly, we received it on Saturday morning. 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 a matter of minutes, and he has recommended it to his motor mechanic friend whowas unaware of it when he spoke to him late last week.

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,Your 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 Parkes Lincs.

22/08/2005 Mark Sallows (Carsem Europe)(Land Rover Discovery 2 (2000 year model) with a leak in the heater matrix).

Colin Turnbull


Delivery service excellent. I am very satisfied with the product & your postal delivery service is great. I Would recommend your company to anybody.Take care.Robin Perrett.


I have received & installed the K-seal product into the cooling system of my wife's MGF and am pleased to inform you that it appears to have solved the problem of a leaky head gasket. I have reported it's apparent success on the SWMGF.ORG site, where i know some of the members have bought the product as a emergency back-up, but i am the 1st on there to use it.


It as been some years since I last dealt with your company and it is a pleasure to see you are still in the trade.I found your address on a old receipt of years ago and I also had your catalogue going back some years,There was umpteen items on Ebay but I chose a company I had dealt with years ago,I prefer quality instead of catalogues and you have a very satisfied customer in my dealings with you Thanking you Gordon Reed


Had a power steering leak on my Rover 600, spent £220 having a second hand pump fitted to no use. The car would lose half a reservior of fluid doing a few miles and half a res. overnight. Bought a bottle of Lucas power steering sealer, put it in last night, ran it around and then topped it up. This

morning no fluid loss, driven it around all day and it works perfectly.Fantastic product, £13 would have saved me £220, I'll know better in future.Thanks very much,Roger Taylor.


great cover,ive bought two the past couple of months they tore easily.found yours alot stronger great product


Hi,my daughter, a Registered child minder, was having what she called problems with her Voyager, it was taking about a litre of water a day in the cooling system, with no sign of a leak, I discovered that it was going into the oil, several local garages could not take the job on as the labour cost they would have to apply were prohibitive, this meant a main dealership was the only solution, the cost would have been well into three figures,I ordered K Seal with the two day delivery, it arrived within twenty four hours, thank you for that, the product was mixed with water and added to the expansion tank as suggested on the web page, problem solved, I changed the oil and filter, there has been no loss of water for over a week now, I mentioned the product to a recently time served mechanic, he had not heard of it, in fact he has got a Toyota Surf in pieces as he had blown the head gasket, he is trying to locate and afford the parts, what a pity he did not at least try K Seal first, Thanks again for a first class service and a first class product.

06/02/07 Thanks for prompt delivery of the car cover i ordered it arrived on time as promised, the operator i spoke to was very helpful and efficient even when it was 8pm at the end of your working day. I will definitely use your company again and recommend it to others.yours sincerely M Clayton
