This is a very small water leak my dash light comes on after about 500 miles ... I'd like to try some UV in the system ... What would be the best UV product to use ... Would I have too flush the coolant afterwards ....

The best way to test the cooling system for leak is to pressure test it. google it.


did you replace/upgrade the coolant TT hose behind the engine? That can fail completely and cause all kinds of damage.

thank you Christuna ... As of yet in looking for the leak ... so i have not replaced anything ... this is such a small leak ...No drips under car
