98 SC2 overheat problem-help

Start car, turn on A/C.

If the radiator fan doesn't turn on, suspect the radiator fan motor.

They're sealed motors, but they have brushes in them. Those brushes wear out. When they do, you get the symptoms that you describe.

Given the 117K miles, your radiator fan is probably worn out. It's a pretty easy job to replace it.

Kirk,

Thanks. That's where I will start tomorrow. Kragen's stock them. should be a quick fix look at the manual. Any pointers from anyone that has changed it already? Things to look out for? Looks simple enough though.

First you should check to see if 12volts are present at the fan motor to properly diagnose the problem. Anyone can throw parts at a problem, especially when it isn't your money.

Before starting the car, unplug the fan motor. Have a mult-meter or 12v test light ready. Start car and turn on A/C. Check for voltage at harness plug. If present, plug fan back in. If fan does not run, then replace motor.

If no voltage present at either wire, then you need to diagnose a bit deeper.

James,

thanks. I didn't think about testing the connector first for voltage. Duh.

I'll do that first.

Even if it does run, you might need to replace the fan motor. At the end of the brush life, the motors become intermittent - they can start working if they're bumped or jiggled.

But, it's a good idea to confirm that you're getting 12 volts to the connector.
