if your clutch does not pass the newspaper test, give Phil a call and order the GERMAN fan clutch! I just got my new one installed today, and WOW the fan is loud on the road when it kicks in!

you should test your fan clutch. get the car up to temp, pop the hood and see if you can gently jam a rolled up newspaper in the fan (GENTLY it's a plastic fan blade) and stop the blades, or does it shred the paper? at full temp on the motor, the fan blades should operate FULL pressure, and they should shred the rolled up newspaper.
odds are good the fan clutch is weak. (they don't last very long really, and it's a good idea to test and replace/rebuild them every 3-5years.

also, the cleanliness of the condenser will have a GREAT impact on the cooling capabilities of the car!

Well, my list for under hood troubleshooting just gets longer.

Thanks for the excellent info!

If they radiator and condenser have never been cleaned the clutch may not receive enough hot air for it to engage. Cleaning both of these should be the first step in any heated or A/C related issues.

Fan kept on truckin'! I'll work down the rest of the trouble shooting list as I have the opportunity.

Thanks, all!
