Liqui MolyRadiator Stop Leak | 150 ml | Cooler additive | SKU: 8956

Q: My heater matrix inside the car is leaking, any good for this

If I were you I would fit a new one, providing its not a Ford granada ghia!! ? I used this on my radiator on my Suzuki Burgman 650, and the radiator split wide open. It didn't work for me, but then my Suzuki has a complicated water way compared to a car. I bought the product with the best feedback, ( stars)but you can't beat doing a job properly, I bought a new radiator in the end.

Q: my astra has a leak coming from the back of the engine could be rubber pipe or freeze plug will this seal it or is it just for the radiator?

Depends on size of leak but there’s no harm in trying it

Q: Can it be used with Antifreeze in the system?

You put it in first to seal off any small leaks then add the anti-freeze.
