Viscous Drive Fan Clutch

67 GTX · May 11, 2015

I installed a new viscous drive fan clutch on my motor. It has no slop, and the belts are correctly tightened. But when I rev the motor in neutral hard, you can hear the clutch, and it as loud as the motor.

Has anyone experienced this before with the original type fan clutch?

Normal operation.

This is just a qwirk of the device itself? Is there any way to quiet it?

I don't hear mine. Either describe it or send us an audio clip. Is it a shreik?

Take it off and send it back. Sounds like the grease has left the bearings. Happens all the time if not stored or shipped right. There should have been a note on the box, store this side up and always store that side up. There should have been a packaging note in the box explaining all this. Hope you have good luck on the replacement.

Hypothetically, they can be set on their face and the fluid will return in a couple/few years. It's pretty darned thick stuff.

I'll try to post a video of it. The sound isn't a constant one, only sometimes on a hard rev in neutral.
