## Questions & Answers

**Q: My heater matrix inside the car is leaking, any good for this**
A: 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?**
A: Depends on size of leak but there’s no harm in trying it

**Q: My motorcycle radiator is weeping slightly will it be ok to use on this**
A: Definitely will sort it out.

**Q: Can it be used with Antifreeze in the system?**
A: You put it in first to seal off any small leaks then add the anti-freeze.
