Engine Cooling problem
2003 Infiniti G35 6 cyl Two Wheel Drive Automatic 192000 miles
On warm days (usually over 80 degrees) my engine will begin to overheat when I am sitting in traffic. If I turn off the A/C the temp will stabilize and I can keep within the operating range but it is on the High end of the scale. If I turn the A/C back on the temp will begin to rise. I don't notice this as much on the open highway but if the outside temp is up over 90, the engine temp will push up to the high side of the scale even in highway driving. Turning off the A/C is the only way to keep within the operating range. When I am sitting in traffic at a red light, I can here the fans kick on so I am pretty sure the fans are operating when called for. I have had the coolant checked at Infiniti and they are telling me it checks OK. Would the Thermostat be the problem?
