I'm deleting it to make room in the engine bay for other items, i.e. different header/turbo setup.
I've got a 2.3 turbo engine in there. I've removed the Oil Cooler from every one of these engine I've had (dozens) and it's never caused a bit of problems with my oil. I'm not worried about that, I just want to simplify the cooling system.
Where do the heater core hoses go on a stock setup (my ranger was already removed when I got it). I know the lower radiator hose is going to the water pump, and the upper hose to the thermostat...but where do I tie in the heater core hoses...and does the 93 Ranger 2.3 setup have an overflow tank for the radiator?
