It's very useful product, I ordered this for my jeep compass, after one month there is no problem with the jeep, It starts working after 4-5 days.

Great product present working well no leakage found ofter using this very good solution of coolant leakage

I have in my Jazz for arresting radiator leakage. After 60km drive run the leakage disappeared

Edit: Did not work for me. After few days and another bottle of Kseal, the leak was getting severe, drive it almost 1 month with Kseal in it, no result. Decided it will be my last attempt, I bought rislone headgasket fix, which completely fixed the problem at last, no more combustion gas in the reservoir or boiling. Rislone contain sodium silicate, it seems sodium silicate do the job, whereas Kseal did not contain sodium silicate.--- end - - - -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
