But thanks to Mr. Paul Grant, he has hooked me up with a relatively new one and is on its way!

Question: What size wrench do I need in lieu of LRT-12-093/LRT-12-094? Mr. Grant thinks it is a 32mm, but by my experience with metric sizes, to me the nut looks slightly bigger than that. Can someone please confirm?

 

Ford fan clutch tool.
I use a really big crescent wrench.

 

Received the water pump today, and the rented fan clutch tool kit from advanced auto parts worked like a charm..

also, my fine motor skills helped make a gasket.

but now I need a new fan clutch. I suspected the fan was running on energizers, and that was confirmed when I noticed the nut is welded to the clutch...

 

There is a write up in the tech area about using a clutch from a 2000 Chevy Express Van 4.3 liter, non/AC (it is a six inch diameter clutch. reverse rotation, same threads as ours - the AC version is larger diameter, don't try that one). In the $50-$60 range. You have to slighty enlarge the mounting holes for the fan blade, the Chevy version uses larger screws.

Also, if on a budget or stuck away from parts stores but near a junk yard - this style clutch is found on a number of late 90's - early 2000's GMC and Chevy, I bought clutch and fan for $19 from the partz vulturez and it works great on my D1 (trimmed fan precisely and carefully).

As for the DIY gasket, you are certainly an artist. A few bucks on line, and $18 at my nearby dealer 50 miles away. I used just RTV much to the dismay of others.

 

For future reference the nut is a 36mm. I found a 32/36mm combo wrench on line for 20 bucks that works for my D1 and my BMW. Just a side note if you get in a pinch and need a 32mm or a 36mm you get pick these up at any high end bike shop as these are the same size wrenches needed for the headsets on road and mtn bikes.

 

Clutch from Advance Auto Parts. This is what I used in my '98 a few weeks ago. In addition to enlarging the mounting holes, you will need different sized bolts. (Non-metric.) I think they were 3/8-16, about 1/2" long.

 

Still no leaks! Hooray!!

What's the deal with using the chevy fan clutch as opposed to a used OEM fan clutch?

I refuse to use RTV.. paper gasket w/ sealant is the way to go to do it right.



I appreciate the posts and suggestions. I think I will make a run to the nearest Pull-A-Part boneyard... they have a couple Discos that I want to get a few parts off of anyway.. as spares.

 

re: I refuse to use RTV.. paper gasket w/ sealant is the way to go to do it right.

I agree, and I regret now my shade tree practice that was done in haste. But it has held for a year.

re: What's the deal with using the chevy fan clutch as opposed to a used OEM fan clutch?

The Chevy (new, widely available, cheaper that oem) would be better than used OEM in many cases, as the used one will have 100,000 miles on it perhaps. And that is married to a different water pump. One thing about water pumps and viscous fan clutches - when one goes, it usually holds hands with the other while it jumps off the cliff. Now if you want more air flow thru the radiator, a stronger fan clutch and different fan (deeper, more pitch) may be of interest. Here is my $19 setup from a 2000 Blazer.

I bring up the alternative fan clutches because not all Rovers break down near a junk yard with a Discovery. But most junkyards have a Chevy or two. And most parts stores have fan clutches for them. It is also possible to drive without a fan at all, just keep moving, don't go thru drive thru, etc. At 50 mph, radiator gets plenty of air from forward motion.

Note: If flying low with the partz vulturez in the boneyard, things that are cheap and useful are alternators, seat switches (careful how you remove them - release on bottom edge), MAF sensor (check what a new one runs), seats (passenger D1 will interchange with driver D1; D2 seats don't fit D1), clock, plastic parts (dash surround for radio has more screws and hidden screws than you think), radiator (if oil and tranny cooler sections are not clogged). Some advanced boneyards will have on-line inventory and even email/text you automatically when a vehicle that you specify come on the yard.

 

The local parts store wanted twice as much for the Land Rover clutch as the Chevy, and didn't even have it in stock. You could probably find an OEM clutch online for less money, if you're adamant about using one. IMHO, the Chevy clutch works just as well. It took maybe five extra minutes to enlarge the holes in the fan (they line right up) and find four bolts amongst the random parts & pieces strewn about my garage.

Savannah: Did you have to trim the blades on that fan to get it to fit under the guard? If so, how did that affect the balance?

 

FYI, flan clutch wrench fro $15.99 at Northern Tool.
