I didn't think you were supposed to mix Dexcool with water
Anyway. I run Prestone all makes/all models, 50/50 mix in all my cars. I changed over to the green a while ago, then put in fresh green when I did my water pump back in 2011. When I did the WP, I changed both the upper and lower hoses, just because they were orginal.
Is the coolant being pushed out of the overflow tube?
