The long of it): For those of us that don’t know, (if any; I didn't) I think many do know there are 2 fan clutches, the ”regular” one and the “Tropical” clutch. I do have the tropical one on our brick.
Well, the last many weeks esp when the weather got real hot, the A/C just wasn’t up to par. I checked what I could, the belts mainly, but all seemed ok. I mentioned this to my mechanic, stating I would like to see if he could resolve this, even if it meant a new clutch, maybe a new thermostat, whatever it needs.
So I leave the brick with him. Several hours later I called and he said it's ready. He mentioned the fan and a/c are working fine now, that the main issue was that the clutch needed to have “grease” added to it. I say: “Grease??” what grease??”
Turns out the clutch has a grease in the assembly, sealed in, but seems those at the “factory” don’t take great care when building the clutch, leaving only a small amount of the grease in it causing the clutch to not work properly esp when its really needed a lot. I had no idea the clutch used any grease. There is some sort of "thing" on the clutch that is made just for putting grease into it if needed.
(I still have no idea how the grease functions to make the fan turn properly.) It’s a “special” type of grease designed for the clutch, some sort of synthetic stuff. So the bottom line now, things are “cool”. The temp gauge never shows hot, and the air actually gets colder than before!. (fingers crossed).
The short of it: If your brick is running hot with the a/c on, and the belts are OK and tightened properly, a good thermostat, check the grease in the fan clutch! The end. (finally)
