Shocking as it is in this weather the ranger overheated, about 4-5 miles from work the heater stoped blowing hot and the temp gauge went to 3/4 (normally at half) then I tried to get it the rest of the way to work and it spiked the gauge so I turned it off and had a buddy at work help push it to the parking lot. I am hoping it is just be the theromstat but it also made funny gurgaling noises in the heater core (no coolant inside?) and a ratchedy noise from the engine bay. I am hoping it is just the thermostat but I might/will be getting a waterpump as well? I have never had at thermostat fail on me any so another new one for my belt notch.
