viscous fan drive

[maxpower1954]

The fan on my R-2 GT Hawk spins about two seconds after shutdown -time for a new viscous fan drive!

Stude part 1560257, but I KNOW there is a direct Mopar/Chrysler interchange, because I did just that some years ago. But I can't find it in my voluminous interchange lists. Does anybody know
what it is? Yes, I would normally get it from one of our friendly vendors, but I just had a large order come in from SI; wanted to try locally first. Thanks, Russ Farris

Are you sure that makes it bad?
Just curious..

Well, that's what I always thought, Jeff - it was supposed to stop turning with the engine. That's what the one on my Avanti does, and this one did also, until recently. Russ Farris

Pretty reliable inicator...

Also, when you rev the engine a bad one will look like it's under a strobe light like the way it looks when you're using a timing light.

most fans should roar when you first crank your car in the morning for a short period of time, this is an easy way to check. it does that because the oil has settled to the bottom overnight. if any oil is leaking out around the shaft you should replace. it will only get worse.

There is not a thermostatic replacement available any more. The repo's work, but are a different design.

For the ones that I have had to go bad. While the fan is still warm after driving...you can grasp the fan and it will wobble on the shaft. That is a good indicator that the viscous drive has given up the ghost.

Yours is bad. Try to find an NOS replacement. As John says, the replacements are non thermostatic. Just oil filled. Not real durable. Some one needs to come up with a better replacement. A thermostatic brand x adaptation, replacement. Anybody up to the task or has it been accomplished. The Studebaker fan is made to accept the larger bolt pattern clutch. I suppose one might be able to redrill the water pump flange and pullies to accept a GM fan clutch. jimmijim

75-80 Caddy, the pilot hole has to be enlarged .005". Easy job with a hand reamer.

That fan ISN'T nesessarally bad...!

A BIG question you didn't offer...and no one asked -
Was the fan hot when you noticed it running on?

That's what they are supposed to do when hot...!

When they are cold/cool, they are tight and...yes, should stop pretty quickly.
When hot, they loosen up and spin a few rotations after shut down.

Read up on them..

Dan Miller in GA makes or did make a kit for Hawks to use a thermostatic fan from a Jaguar. I have the kit on and it works fine. The clutch is from a '85 to '87 XJ6 or '85 to '92 XJS.

I believe he said that there was not quite enough clearance to use this on a Lark. He was selling these at the 2007 Nationals in SB.

Thanks Alan, but there are at least two different fan clutches for Caddies for those years on the NAPA site - can you narrow it down a little more? Russ Farris

I got the fan clutch below from Dave Thibault from Maryland for my Champ pickup. Too bad the thermostatic clutch will only work for the Hawks...
