Another Moly win
So I had a leak from the radiator that was spraying coolant on the power steering belt….the engine cover always has liquid spots on it too. Added this, took for a 20 min drive and all is well, no more spray no more missing coolant. Easy to use and now I can take “car radiator” out of my shopping basket!

Done what us says on the tin, coining the phrase.
Just shake well and poor into the cooling system, either by radiator cap or coolant overfill bottle. Run car static for five mins with filler cap off. Stop engine. Pour the contents into the coolent filler, place filler cap back on. Do a short drive, five miles in my case. Appears to have fixed the mystery coolent loss.

Wow! Car sale possible!
We had a 17 told car that had a leaking radiator but we only needed to patch it up to sell it so used this.One thing led to another and a half a year later we still had the car and the liqui moly was still doing it’s thing.£20 or £400 to fix the radiator and this stuff worked wonders!

Did not fix leak and was waste of time and money.
Why did you choose this product over others?:Followed the instrucitons and put the whole amount into the cold radiator and did not stop the leak. Hole was small and, according to the description, it should have filled it and stopped leak. Still leaking and complete waste of money. Not happy. Not recommended.

Worked wonderfully well on an old tractor.
I was surprised how well this worked. I thought the radiator was dead! Perfect.
