In the middle of summer, I started to notice that my car would run at about 105 C. Thats about 10 to 15 degrees higher than normal. I just figured it was because it was a really hot day. Then I started to notice that on the same day it would run at its normal temp of 90 to 95, I would shut it off and go in to a shop or something, and come back and it would be running at like 105 again. I figured I should start investigating more. I left for holidays, and came back just over a week ago, and the car was doing the same stuff, except the temp outside was a little cooler. Today however, my car was running at like 117 C, and it red lines at 135 c. So now I am really worried. Does anyone have any suggestions??

The radiator is about 1 year old. It looks in good condition. Im not leaking any fluid anywhere that I can see. My cars not puffing white smoke. So I am thinking that its the water pump?? How would I test that?? Could my thermostat be sticking?? WOuld blockages somewhere in the system cause these symptoms?? Any info would be greatful.

I talked to a parts guy, and he said that it could be my Heater core. Is this possible??

 

Yes. Your radiator may need to be "rodded out" (thouroughly cleaned). I'd replace the stat as well.
