Good afternoon everyone,

I've got a failed thermostat on my 08 FEH (Stuck open). My coolant temp never exceeds 65 degrees celsius.

I'm going to attempt to swap it out myself and was wondering about the coolant itself. I've owned my FEH for about 6yrs now and have never done a coolant flush so was going to do both the engine cooling, as well as the electronics cooling system.

My question is this... I understand I need MotorCraft Gold coolant for the engine but does the electronics cooling use the same?
