Replaced Fan Clutch on FB, Much Quieter!
 

I have an 81 FB w/ 53K miles, OE fan clutch spun easily with a bit of resistance cold, could be stopped with a gloved hand when running & hot, but would intermittently seem to lock up and make a helluva roaring air/fan noise when driving. Not a pleasant engine sound, an annoying air movement roar. Was hard to hear the engine over the fan roar.

Finally bit the bullet & bought a new fan clutch & replaced it, wow, what a nice difference! Now it sounds like a rotary engine & not a Shop Vac.

If you have the same symptoms, do yourself a favor & change it out, you'll be a happier rotary driver as a result.

Good to hear you fix the issue. I also had a bad fan clutch. I finally got it replaced and it sounds so much better. My old fan clutch would squeal around 3k rmp it was annoy.

Thats the belts squealing. Not good on your engine.

That's what I thought at first too, but after replacing the fan clutch that noise stopped. I'll check the belts (previous owner installed dual pulley's).

Overheating
 

Victory!

I was able to 'drive' her home from the doctor today. NO overheating.

All said thermostat, water pump, radiator and fan clutch replaced.

Not a peep from the coolant system the entire way home. Thanks too all who provided comment.

That oil 🛢 though. Now IT wants to ride high when I'm above 45 and in and out of 3rd and 4th.

Any thoughts on that?

any particular reason why u posted this in a 7 yr old thread instead of in one of several threads u have going on this issue? keep in mind that random posting makes it difficult for others to find when searching the forum.

Doing it on the move with my phone.

I thought it was the ongoing conversation.

I'll do better.

Thanks for letting me know.
