1997 Oldsmobile Aurora cooling fans
1997 Oldsmobile Aurora V8 Front Wheel Drive Automatic 127000 miles
engine cooling fans only start when AC on
Asked by steetorAnswer
What is the temp gage reading, sometimes it takes a while for the coolant temp to get up there. Yes, the fan will run if ac is turned on. Does the engine reach normal operating temp?
yes, it reaches normal temp and beyond
What is the temp gage reading? Any applicable trouble codes?
it has reached 240, then I turn on the AC so fans turn on. Shouldn't fans turn on about 220? Is it a relay problem? Where is high speed relay located?
My info says around 230. The coolant temp sensor could cause an issue? I can't be certain if the sensor is faulty. How many fans do you have? If more than one, do all the fans turn on?
There are 2 fans. Both turn-on when AC is engaged. The temp guage shows temp increase, so temp probe seems OK. Where is temp sensor located? Where are cooling fans relays located?
The fan relay locations are in the diagram. I might have to use an infra-red noncontact thermomter to see if engine temp and gage show about the same? The coolant temp sensor is circle c in the diagram.
