Well I got my new water pump on and also put a new belt tensinor (sp). Filled up all the fluids and made sure they are full. Now when I drive, my car is around 195 range then jumps to 210, stays for awhile unless I give it some gas and goes to about 230-240 then drops back down to 210. If I get on the freeway and take it up to about 70-80, it cools down a bit, but then I hit stoplights and it starts doing the 210-240 range again. Did I miss something or do I have another problem?? Not enough coolant, thermostat??? Any help is appreciated. Thanks!!

 

I did the same thing 6 mos ago, i still had the problem after changing my water pump. Figured out i had air lock. Maybe try gettin your cooling system bled.

 

use the bleed screw buy th thermo, if not i would try a new thremo only few bucks
