That whiney, raspy sound, that I though was coming from my A/C compressor, is actually generated by the A/C fan in front of the radiator. Whooo-Hooo!! Are there any upgrades, or other interesting things, that should be done when replacing this fan, or is it just a straight in/out?

Is the VOV upgrade, that I've just read 76 messages about, also applicable to the 1990 760T? I'm in Phoenix AZ (yeah....it's a little toasty); should I be looking at the extreme duty VOV or is that reserved for shuttle re-entry, roaming around the surface of Mercury, etc? Thanks!!

You might need the severe duty one. I'm not sure where the cutoff is with that, but I think it's like "temperatures frequently over 95 degrees" or something to that effect.

The condenser fan can easily be replaced by an aftermarket one if you're so inclined. That way you save a ton of money. Get the BIGGEST fan you can shoehorn onto the condenser. That'll make you happier still.

The VOV upgrade is nice but unless you have poor cooling, I'd just wait until the system needs service (i.e. needs to be opened up). It does get you better vent temps though.

Well, I'd like to report at least short-lived success in cleaning and "re-lubricating" the screachy condensor fan. After pulling it from its resting place, I was impressed by the amount of dry, dark brown/black dust that came out of the innards of the fan motor, not to mention the assortment of flora and fauna caught between the body of the fan and the condensor fins. A quart of Simpler Green, a half pint of rubber and vinyl dressing, and a considerable quantity of WD40 later, the original fan has been re-installed with nary a squeek. We'll see how long this "repair" lasts, and how long that $240 for a new one can remain in my wallet. If it really is a short-lived fix, I'll report back and possibly save someone the trouble. Thanks for your help!!
