Re: Upgrading The Fan Clutch
Good writeup, very helpful with pics too! :thumbup:
Re: Upgrading The Fan Clutch
Looks good, added to my long list of mods.
Re: Upgrading The Fan Clutch
Bumpin on old thread. :D David, how did this work out? Did you notice a drop in mpg's now that the fan is being used more often? I am planning on redoing the fan clutch in my van and was thinking that this may be an option if it doesn't affect the mpg's too much.
Did you order the oil from a dealership and just requested a heavier oil?
NIce writeup, I'll be using it to do mine, even if I just go with the stock oil. :thumbup:

You can also get the oil from a hobby shop that has RC car stuff. It's silicone diff fluid and it's supposed to be better than the toyota fluid. I bet if you go into the dealer and say you want fan clutch fluid, without a part number, they'll give you a blank stare.

Re: Upgrading The Fan Clutch
Thanks Steve, that's a great link!
Edit: I asked NTP for a price quote on the silicone, so I'll see if they find it. :D

X2 I am curious on the MPG diff as well
Re: Upgrading The Fan Clutch
Sorry for taking so long to respond on this. As for the mpg, didn't really notice a difference. I did this mod because my A/C wasn't working great and my temp was running a little high. After doing the mod, my A/C did get cooler and took longer for my engine to start overheating. (I ended up having to replace my radiator, which was the actual cause of the overheating) If you live in the desert area, I'd recomend this. Also, it will extend the life of the fan.
Re: Upgrading The Fan Clutch
One thing to be aware of is if you have the fan with the ring around the perimeter, it would be wise to replace it with a newer ringless fan. In fact, I would be leary of any older fan regardless of whether it has a ring and would replace it with a new one. It makes a mess when they explode.
That's one reason I haven't rebuilt my fan clutch yet. The higher viscosity will spin the fan at high rpms longer than the lower viscosity fan.

I just learned about that older ring fan the other day. Went and checked the 4runner and it has one of those darn things. :(
