Fan Clutch Replacement?
Hey,
My fan clutch went out today when I was driving home from Tech School on my 1991 Toyota 4Runner w/the 3VZ-E engine. Has anybody ever replaced one or know how hard it is?

It was my understanding that a fan clutch is a fluid clutch that works off of the temperature of the coolant. I'd also like to know how something like that would eventually break, being a fluid clutch.

Mine has gone bad. All the fluid leaked out and the fan would freewheel - not cooling the engine. You can buy a new seal and fluid for the fan clutch but I didn't mess with that. I got a new fan clutch and it took about 30 minutes to replace. The hardest part is unbolting the fan clutch from the pulley assembly. I think I had to take out my fan shroud to remove the fan/fan clutch assembly. Once out of the truck it was easy to swap the fan onto the new clutch and then bolt the sucker back in.

i thinks its bad beacause i can spin the fan with absolutley no resistance and it continues to spin for about 2 min after the engine is off, also the fan wobbels about 2 inches out when spinning. i had my auto instructor look at it and he agrees. but what would you think about replacing it with a hayden electric fan? right now im just planning on replacing the fan clutch.

You can just refill the viscous clutch.
Here you can see some pics of when I did mine.

The Toyota part # for the silicon oil is 08816-03001. I used two.

you can get the "hayden" fan from advance or kragen, for about $100, a guy at school put one on his 2.7 and gained a little MPG, plus on deep water crossings you can turn them off, i guess that could help a bit, i've been looking at them, but can't talk myself into one yet

Iam in the same boat, about to replace my fan clutch, I was told by an old timer that its worth to buy the factory fan clutch because the haydens wear out fast. So.. I went to the dealer, 146.00. Well Iam in there Iam going to replace the radiator ,fan shroud, water pump, and thermostat.
