Default 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?

maybe it's because of the cold weather that it is changing.don't worry about it ! or you could check to see if your thermostat is stuck open that will also cause what you are concerned about !

My suggestion would be to take your old ranger to a reputable repair facility and pay the 20 bucks to have the cooling system pressure tested and have a block test performed by a professional. That is money well spent imo.

As long as it's in the safe range you're fine. It goes down when you accelerate because the water pump is pumping harder and the air is blowing across the radiator in greater quantity.
