Tuning and Understanding your Toyota Viscous Fan Clutch

Thanks for the URL on the fan clutch. It was especially interesting to note that new clutches don't have enough of the silicone coupling fluid. I am going to do some experimenting because my 2F gets a bit warm at sustained high speeds here in hot Texas.

Such well-written articles are rare, and need to be shared. I'm about to fire up the V8 in my 45 for the first time - also in sunny/humid climes - and from everything I've read getting all cooling components tip top is essential.

there's tons of information on the fan clutch fluid re-juicing here on MUD as well; a lot of those in the 80 series forum - search for threads "Tools R Us" posted in for information on various fan clutches

Good artical, read it before. But IMOP re juicing the FC is a waste of time and money, never been happy with the results. Get a new aisin.

However. ...the FC should not be doing much of anything at hwy speeds to help cooling. I would look into why it gets hot.

Biggest trick with rebuilding a fan clutch is paying attention to the thermal spring - if it's badly rusted it's junk since the spring's response has changed a lot - best to replace at that point . I had one off a mini truck re-plated and it worked pretty well but was somewhat slow to respond .
