My '98 runs hot on low rpms but I can cool it off by knocking it into neutral and revving to 2/3.5K rpm to avoid overheating. It has become a real hassle so I need to take action before I crack a head. I replaced radiator and thermostat/all hoses when I got it about 4 mos ago. Per posts her I think the fan clutch is bad & am planning to replace. Any idea what the torque specs are for the fan clutch?

Also, although I am not leaking water, I am thinking to replace the water pump since I will already be "in there". Anyone recommend a particular brand? I want something HD if it is out there.

Many thanks!

Jac if you are going to be in there--you should do the timing belt also......

Torque values for the fan clutch--you should be fine with just tightening them down--firm but not Arnold tight.

Did you know that thing behind the fan clutch that looks like a water pump isn't really the water pump?

Thanks - I have the Chilton manual and it helped me locate the H2O pump. What is that thing behind the fan clutch anyway?

Its called the fan bracket bearing or fake water pump. All it does is support the fan and belt pulley. They do sometimes go bad.

That thing behind the fan is just a bracket/bearing for the fan.......The water pump is nothing like on a chevy--it is involved--but doable

As far as the torque spec it can probably be found in one of these FSM http://www.ncttora.com/fsm/index.html. But you'll have a hard time getting a torque wrench in there.

Thanks to all for your input!

If you still want to do the water pump here's a writeup on doing it and the timing belt:
