Incredible

I can't actually believe this worked, would recommend this product to everyone! Was really sceptical about it, my car wouldn't even drive 2 miles without boiling over, put the product in and an hour later I can do what I want, I own a large truck so repair work on the gasket would have cost me thousands, 18 quid you cannot go wrong, thanks to the genius that invented this product!

Waste of money, it makes bigger mess than head gasket issue itself

I used that product according to the instructions of volume (about 70% of one bootle for 1.0 litre, 3 cylinder engine) and proper substance for mix (deonised water). At the beginning car has passed the head gasket test, so I thought it's fine now. Next day, when car cooled down I've noticed big problems with ignition, then I smelled gasoline in the coolant tank. Before ,,repair" I've still had a running car, at least to the workshop. Now car won't go. Don't look at the date of purchase, because my time was too short to deal with this car so I can say that after repair car stopped working at all and I've got recordings showing the entire process. Total waste of moneyRead full review

Worked for 5 days only.

The bottle actually looked like someone made the product at home.
I followed all the instructions drained coolant and added water 3 times until it was diluted enough to add Dr headgasket, added it , ran the engine for an hour etc. Worked beautifuly but only for 5 days. Day 6 coolant warning light came on, water level low, back to where I had began.Read full review

Don't waste your money

Followed all the instructions, but it did not work at all. Who knows, maybe it works for certain types of failures but not in my case.

Seemed to work with no issues

Emptied the radiator and also the top up container. Entered this solution along with distilled water. For about 15 mins I forgot to turn on the heater to full but did so for the next 45 mins or so. When it was finished it appeared to have stopped the leak so I sold the car. My only concern was that I no longer had any coolant so it it got really cold would it cause some damage to the radiator but wasn’t sure whether I should drain some out or what so I left it!Read full review

Excellent product. Head gasket was leaking badly (lots of coolant in engine oil), I followed the instructions and this product worked perfectly. It's now been in for 1 month and hasn't lost a drop of coolant. Thanks!Read full review

DID NOT WORK

I had a mechanic do it and he followed the instructions to the letter. And it did nothing to solve my problem. Make fancy claim but over rated.
