With A/C On, It Overheats

courtesy of Bob, The Auto Answer Man


Bob,
I have a 1985 Ford Ranger, XLT, 2.8 (171). My engine starts to overheat every time I turn on my A/C. When I turn the A/C off, the gauge returns to normal. Periodically, my oil pressure and temperature gauges will both peg out high the return to normal but that has not happened in a while. My problem is the overheating when the A/C is on. Any suggestions?
Pat


Pat,
I bet the cooling fan is not working properly. The 2.8 is a v-6, right? That's a pretty decent motor and the a/c should not put on so much load that it over heats it. I bet that the cooling fan is not operating correctly. Is there one or two fans in there? If two, then the second one (for the a/c load) is not coming on. If only one and it is driven by the engine, then I bet the thermostatic clutch is malfunctioning!
Good Luck!
Drive Safely!
