Car Overheating....HELP!

[TMASTER]

SO your saying that during the day while the AC is on, the car overheats and tops out the Temp gauge? Mine was doing the same thing before I replaced all my cooling parts.
It turns out that my radiator was old and had lots of bad cloggin buildup in it.

I have new radiator stock 2 core, 160 thermo, and a new water pump. Mine sits at 40 to 50% during the day AC on. Here in Texas.

Also your pulleys are slowing down the waterpump flow, I put stock ones back on and mine runs 15% cooler now.

But your water pump might be bad, couldn't hurt replacing it for $30-40.
Check for green slime in the cores of the radiator, when the cap is off
Also Check the radiator cap, when the car is hot, for the cap leaking, might need a new cap.
If you do replace the waterpump, put a new thermostat in also its cheap insurance.

Hope all this helps! I think it will
