Does anyone know what size the viscous fan nut *is*? RAVE just says "use special wrench, part number MUMBLE"

 

Advance Auto will lend you the wrenches for free (requires a $50 deposit - refunded as long as you return the wrenches within 45 days). BTW the viscous fan nut is 36mm. If it is your water pump, I recommend buying a new one over a used one - the difference in cost is not significant enough considering the time involved replacing it, unless you really enjoy removing these puppies as a hobby.

 

well with that many miles its time for a new hoses and a water pump from atlantic british. just remember to take off the clutch and then loosen the bolts on the water pump before taking off the belt.

 

Yeah, Rovahfarm is *1/3* the price on a new pump; I'll wait for them to ship it. Advance has the wrenches; the deposit's actually $60 in this market (you buy them, and then return them).

I've pulled the shroud, and extracted the remains of the belt (pic to follow as soon as I figure out how to get it out of my phone :-), and I can *see* that the axis of that pulley is off line from the axis of all the other sheaves that the serpentine travels over. I can't move it much, though, even though the belt's off now; clearly, it's jammed into the pump housing. Probably gonna go grab the wrenches tomorrow and do the pull, then order the pump on Monday.

Happily, I'm one bus ride and 20 minutes from where I work.

Really seriously considering the "buy a second car" approach, though.

One tech question: What do you work *against* with the wrench? RAVE shows *two* special tools, but it's not clear what the other one goes on/into.

 

you have to hold the pulley. they may have a pulley holder. if not then try a pair of pliers.

wont be easy with the thing loose and shredded.

 

Here is how I did it, works every time. Northern Tool sells a 36 mm wrench for cheap. The ford clutch fan kit from Autozone costs $20 or so last I checked. Here is a tool like in the rave CD:

Edit: This only works if you can keep tension on the belt which I'm not sure you can. You can build a pulley spanner erector set style in a "y" to go in a hole on each side of the wrench instead of just one like I did. I've also seen people just use a vise grip to hold the pulley, care though the edges crack easily.

 

And the thread MojaveMike refers to over there is at

Yeah I could not get that to work hence the redneck spanner I made.

 

My water pump went out 900 miles from home, so I had to buy one from Autozone for $162. I just helped a friend replace the water pump on his 99 BMW 525i. The bearing disintegrated, broke the belt and then the fan hit the radiator putting holes all in it. We had to replace the water pump, fan blade, belt and radiator. So if your radiator is still good, feel lucky!

 

In fact I was very impressed: there's quite a lot of clearance between the fan and the radiator; the clearance got *larger* from the failure, and the fan is shrouded on that side anyway, probably specifically to reduce the chances of holing out the radiator.

I rather liked his Stilson approach, lip, but if I can't find one small enough (since that's the most likely trouble), then I'll move on to your approach.
