Ford Ranger Temperature Fluctuation?
So I've got a 2000 Ranger with the 2.5 engine. A couple of days ago I was driving to school and noticed the temperature gauge was below normal. Normal is halfway between Hot and Cold. It would go back up to about normal then eventually drop some and so forth. I got to school and checked things out and it did not appear to be leaking any coolant. It seems to drop more significantly upon acceleration and return to normal either at idle or when cruising. Any pointers?
