Engine Cooling problem
2005 Chevy Colorado Four Wheel Drive Automatic 148000 miles

I have a 2005 Colorado 5 cyl that's been running warmer than normal the last 2 day? The temp have only been in the High 70's. What maybe causing this problem. It never over heated.

Thanks

make sure your coolant is full first. then disconnect your fans if they are electric and feel your radiator for being the same temp all over. if you feel cold spots your radiator may be bad as it should feel the same all over. also check your system for leaksby having apro pressure check it.
