Re: engine coolant temp sensor in olds 88
The cooling fans are turned on/off by the PCM module through cooling fan relays. The PCM references the engine coolant temperature sensor (ECT) and the A/C pressure switch. Therefore, the fans may not turn on until engine temperature reaches the 212 degrees with A/C off.
Do the fans turn on with the A/C on? Any driveabiity problems?
