Cooling issues
Hello everyone. Starting yesterday I noticed some cooling problems with my Ranger. I had a very sudden temperature spike (almost to overheat on the dash) and then it very suddenly went back down to normal. Is this a sign that something like my thermostat is going? I did have the water pump replaced before I left New Mexico for Jacksonville, Florida to start law school. I also noticed that my temperature has been fluctuating more than it did before I had the pump replaced (I have a scan gauge II). I'm hoping to get into a dealership to have them take a look at the whole cooling system for me this weekend. Thanks for the advice.

What kind of shape was the coolant & cooling system in when you worked on it back then & how does the coolant look now????
What were you doing when you noticed the temp spike????
BTW, it would be helpful to those offering trouble shooting thoughts if you'd add your Rangers particulars in your signature, or post, so we know what engine, tranny, differential, brakes, ect you have.

Since the cooling system innards looked ok, have you been hearing any untoward noise from the cooling fan clutch, or fan belt. Does the serp belt look ok & the tensioner range marks indicate belt tension is within range????
Have you ever replaced the radiator cap, or had it checked to see if its ok & holding pressure within range & its gasket sealing surface is undamaged????
