Forgive these basic terms.

In front of the engine near the grill my truck has a big fan. It seems that a bearing has gone bad and now it is kinda noisy and very squeeky.

To cure this noise, where would i spray WD-40. Or would it be better to just find a new fan that is similiar to it.

This fan is important to cool the water in your radiator. You need it to keep your engine from overheating. Seek a junk-yard and find a replacement. It should take 20-30 mins to replace.

You mean the water pump bearing? That's a $30.00 part and good hour's worth of labor.

Try jiggling the fan to see if the bearing is loose. There should be no play in it at all. It's probably seeping coolant as well.

Sometimes the fan is just driven directly off the belt, and has no connection whatsoever to the water pump...

No it isn't the water pump. It is a regular fan.... just like what we have in our happy little PC's only bigger (A lot). And it is merely making a racket.

SHould have anything to do with the rest of the car. Ill see if i can take a pic of the Fan.

Just checked. The fan is belt driven.

You have the belts going like this > and at the bottom it is attached to the fan. Is there any way to lubricate it (WD-40) or is there anyway to swap it out.

It is belt driven. :(

I do not want to spray WD-40 near it because im worried that some might get on the belt and cause it to slip.

Ill just deal with the noise. I think the problem is, im trying to make a 1992 car look, feel, and drive like a new one. It isn't gonna happen :p

WATER PUMP REPLACEMENT
  • Most cars on the road today are water cooled. This means the heat from the burning fuel is absorbed by a "water jacket" around the cylinders and the dissipated by the radiator. In order for this to work, a water pump must circulate the water through the engine and radiator.
    Water pumps fail in two different ways: Water leakage and bearing failure.

    Check bearings like this: Wiggle the fan blade (on rear wheel drive, belt driven water pump applications) There should be very little play in the water pump bearing. On engines with electric fans, wiggle on the drive pulley to the water pump. There shouldn't be play (looseness) in the shaft.

    Check leakage like this: Water pumps usually start leaking slowly: occaisional need to add water and spots of coolant on your driveway after a hot day can be from the water pump, especially when you can see no obvious other leak (like a hose or the radiator). When you can get to it to see it, there is always a little hole behind the pulley which drives the pump. This hole is to allow the tiny amount of water which normally comes past a seal (a few drops per year) to get out rather than wash through the water pump bearings. When seals fail, water pours from this hole. Often you'll see stains on the pump housing by this hole on a leaky pump.

    I've seen pumps with no play in the bearings leak, and I've seen pumps with totally shot beaings not leak a drop, so it pays to check this if you've got more than 60,000 miles on your car.

Try rubbing a bar of soap on the inside of the fan, of couse with the engine shut off.

Year, make, and model.

Please.

ANYBODY posting a YACT for mechanical advice, always supply this info. You wouldn't post a computer question without naming the motherboard and CPU, would you?

Thank you.

First of all: what car and engine?

And if you know: is the fan clutched or directly driven by the belts?

Aren't fans that are belt driven almost always integral with the water pump?

Yes its the water pump bearing dying. Keep an eye out for coolant leaking once that starts happening its time to replace it.

It depends...but usually yes. There is usually a fan clutch between the water pump pully and the fan itself.

It could be the fan clutch dying....or the belt slipping....

The car is a 1992 Toyota 4x4

Rear wheel drive with locking hubs.

Engine is a 3.0 Liter V6

5 Speed Manual Transmission

If you need more specifics on the engine ill have to find the owners manual, because i cannot remember some of this.

My Dakota's fan can be replaced without touching the water pump. I don't know how your Toyota's is configured, but there is a clutch that engages teh fan when it's needed. That clutch may need to be replaced

Is it just squeaky, or is there some mechanical noise? I don't think the WD-40 will make the belt slip any more than it's slipping now (if it is slipping).

The serpentine belt on my old truck would squeak like crazy when it got damp outside or rained. It was pretty embarassing in parking garages and stuff. I tried belt dressing on it (spray can stuff you can buy in auto parts stores), but it was a temporary fix. Even thought the old belt looked fine (no cracks or fraying), a new belt made it permanently better.
