Ahhh! Help please. So much confusion! I'm just minutes from replacing my first WP (102k miles and stock still good) and I don't know now what coolant use. I checked my reservoir and it looks like Yellow. According to what was posted on other threads that's the Ford coolant, but I can't find it anywhere around.
My question now is:
Can I replace what I will loose from the WP replacement with water?
If not, can I add Zerex (Valvoline Dexcool alternative) to replace that?
