Ive about had it with the fan on my 95 3.4, when I first start the engine the fan sounds like a jet engine! Its hard to talk over it. Ive been threatening to install an electric fan I heard a 16" Derale electric fan is the way to go. how hard are they to hook up? surely they come with a kit or something with relays, temp sensors, and what not right? and is that truely the best one?:thumbup:

Does the sound quiet down after the engine warms up? If it does it is due to the fast idle. Most toyoata engines have a fast idle on them. Which incraeses the idle speed until the engine warms up. If it does not quiet down after idle I would check to see if the fan is damaged, installed backwards, the fan clutch is defective, if the belts are loose, or if the bearings in the fan pulley are bad.

Yes after it warms up it slows down, but untill it then all it does is leech HP and probably takes that much longer to warm up. I also know how much a fan clutch costs and its not that far from a brand new electric fan. but I guess there are pros and cons about them both.

If the engine is taking a long time to warm up, you have other issues. If the fan clutch is defective replace it. It is possible that if the fan is always engaged it is causing the engine to take longer to warm up. It is not a hard procedure and can be done in less than 4hrs.

The fast idle is factory programmed on all v6's that I can think of. It has never been a problem for me. A bit of a nuisance yes, but not a problem.

good luck
