Topic: 22re fan clutch and water pump.

[MilesGC1999]

So, I am going to be replacing my fan clutch in my 94 Toyota pickup 4x4. I have read that when you replace a fan clutch that is going out it is a good idea to replace the water pump. What do you guys think? What parts should do you recommend?

Hey Spooky...

Unless the water pump is leaking coolant or making a noise, I would not replace the water pump just because I'm replacing the fan clutch.

Regarding the water pump... remember to maintain fresh coolant per recommended maintenance periods.  The coolant helps to lubricate the water pump, which helps prevent early water pump shaft failure.

Has the fan clutch failed?

Ok, my fan is starting to fail. Don't want it to fAil when I don't have time to fix. So I am replacing it. Can't be breaking down on the way to school or work.

When you have the fan off spin the water pump and feel the bearing. If it feels gritty or loose replace it.

Not sure if I'm playing the devil's advocate or not, but I swapped in an electric fan about a year ago.

If I'm traveling over 20mph, even in the summer, my fan doesn't turn on, and temp stays dead center.

So don't worry if your fan clutch goes out. Just keep on driving, pushing air through your radiator. I can sit through 5 blocks of stop lights before it barely starts to rise above half way.

Good luck though 👍

Never heard of that recommendation for a 22re, more common is the water pump when you do the timing belt on a 3.0 due to having to remove it to replace the belt.

This, otherwise only replace when it is leaking, or if you are doing a complete rebuild and want all new parts.

Although there are applications where converting to electric fan(s) may be a good option, and there are guys who say they work really good, and this discussion has been around...

In all 3 of my 22s, living here in sunny AZ - summer time ambients often go up to 115+d F , I have never had an overheating issue unless the thermostat failed, or the water pump went out and leaked coolant before I realized what happened.  I've pulled a 21ft ski boat on tandem trailer in July, and never had an issue with coolant temperature with stock radiator and stock fan clutch.

The fan clutch is about $40 from O'Reilly's.  The cheapest electric fan is about $100, and the high quality ones go up to almost $300.

So should I just get a clutch from an auto parts store?

I would buy one from NAPA, O'Reilly's, or Autozone, etc.  I have a brand new one from O'Reilly's, I'm about to install.

Ok, thanks.

I have to pull the radiator to swap one in my 1986.

The fan clutch? I don't think it will be hard with this one. A lot of room in front.

You can pull the fan without moving the radiator. When mine started to go I just ordered up new oil from Toyota and let the old drain out and put the new in.

Oil for the fan?

[kneedownnate]

  it isn't cheap, but I would rather keep my toyota parts than get one from an auto parts store.  Or you can do a little looking online and find an inexpensive aisin or advics unit

Yep, you can replace the viscous fluid.

I'll just buy a new one.   

On mine the clutch function was OK, the shaft was wobbling.
