K-SEAL Permanent COOLANT Leak Repair Liquid 236ml - Stop Radiator Leak, Head Gasket Repair,Block/Head Sealer-No Draining/No Flushing,for All Cars, Light Trucks, Heavy Trucks & Buses

My car often overheat, air bubbles in radiator and it would blow all the coolant out in reservoir and did not even return to radiator due to air pressure from blown head gasket. Once it overheat, I had to suck coolant from reservoir and manually fill in radiator. Sometimes coolant will overflow from the reservoir tank. I enquire several workshop and they confirm its blow headgasket and the minimum charges will be ₹50,000 and I was told it can vary even till ₹1lakh!! With despair I started to check several reddit comments in self repair and luckily I had gone through this product K-Seal.The day this product it arrived, I did everything as instructions, fill full bottle in my suv radiator and I am very disappointed with the results as I didn't see any instant results as some stated in the comments. I didn't flash the K-Seal and let in inside the radiator whole night. Next day I started the engine, trying to park and lift my vehicle 45% incline as advance guide manual for blown gasket treatment, but did see any results even on 2nd day.After 3 days, I took the vehicle with full passanger inside my car, and if the load is heavy my car tend to overheat easier. Went to see football match and as we are about to go home, I check the coolant tank, to my surprise, all the overflow is suck back to radiator which never happen. Once I started the vehicle, I notice the engine sound change and began to drive smoothly.I purposely drive on 1-2-3 gear for a long time to see if its overheating (with blown headgasket, it definitely overheat in bigger gear) but to my surprise, nothing happened. Now engine is in normal condition and cooling system work fine as it suppose to be.My advice is not to flash K-Seal even though it may not work instantly, but it will work eventually. I even thought my car damage is too big, even K-Seal can no longer do its job. In advance repair guide, K-Seal mentioned that it may take 10 days (in cool & hot engine cycle process). I wish K-Seal made that instructions/expectations in the bottle instruction but which is only available at their website. I'll try to update this comment after few months or if any failure happens again in future.I am from Bangalore, India. Youtube channel: Daniel Lalzuitluanga

There was a minor leak in my cars radiatorWhere as i have to top up the coolant in every 3 days.It confirmed that it’s a time consuming process and expensive as well.Then I saw about Kseal leak repairI used it and I am totally satisfied with the resultAlso I am posting this review after a monthTotally issue resolvedThanks for such a great product

I had observed oil leak signs in the coolant, Probably faulty oil cooler gasket or Engine head gasket. I poured this liquid to the radiator and drove my Thar crde for almost 30minutes.Next day had gone for 400kms drive as well. No further oil leakage. Coolant looks clean now.Its been almost 3 weeks now. Oil mixing with coolant has stopped perfectly.

Dear Amazon Customers,I would not recommend purchasing this product. Despite following all the provided guidelines, the coolant leaked after reaching the engine temperature. It feels like a waste of money, especially for just 236 ml priced at 1100. I trusted the reviews when I bought it, but I am now very disappointed.

It has worked for me. Must try this before big repair work.

I had very minute leak in the coolant system in my VW Jetta. Every month i used to top up coolant. I took the vehicle to 5 different workshops. None of them were able to trace the leak as it was very minute. I poured K seal in the coolant tank and ran Heater for 15 mins. The leakage has completely stopped. Its been 2 months and level of coolant has not dropped at all. It works well in minute untraceable leaks.

I had a small hole in my skoda superb. But after using this product the problem increased instead of solving

I was sceptical but it did really work! Took 4-5 cooling and heating cycles b4 the problem was resolved!
