I want to use Bars coolant system fix. It says to put in radiator if possible. If my radiator is full should I drain some and then add the coolant fix product? Or put it in the overflow reservoir? I never use leak stops as a rule but we are just trying to get as many miles as we can before I replace the car.
Thanks so much!
have the same problem?
