2001 D2 fan removal

[kcabpilot]

I'm having a heck of a time getting the viscous fan off my 2001 D2. I borrowed a 36 mm spanner and made a tool to hold the pulley but she ain't budging. The manual says it RH thread which I interpret as standard so standing in front of the radiator facing aft I am trying to remove by turning CCW - pushing the spanner handle to the left.

I'm pretty sure that's right but hey, I've been wrong before.

Any other tips welcome

Yes, it is standard thread and a real pain to get off. Keep trying I had to work on it for 2 hours!!!

You're correct about which direction, but why are you pulling the fan? If it's to change your belt, it can be done very easily without pulling the fan.

A real fast swat with a hammer to the wrench can break it loose in most cases. I always use anti-sieze on the threads before putting one back on too.

x2 for the hammer. A hammer and a real wrench works way better than the Land Rover special tool for removing the fan.

Major coolant leak. Hard to tell right now but it's either water pump or timing cover.

I've never had that work. I have a universal pulley holder that makes it about a 10 second job and no worries about wrenches flying across the garage at high velocity. An air hammer will get it off too.

I spent hours trying to my fan clutch off last summer...

If you're using a loaner wrench from an auto parts store, get a ruler and measure it to make sure it's actually 36mm. I borrowed several from different parts stores and discovered that they were all 'stretched' out to 38 or even 40mm.

When I finally got a fan clutch wrench that was really 36mm, the job was a breeze.

NOTE: All of the above advice is also good assuming you're using a tool that is in proper working order.

air hammer and a lisle fan tool set, if you have a compressor and an air hammer.

I've got a good tool (36mm spanner) and made a pulley holder out of some flat stock. I think maybe I just need a second set of hands. Just wanted to be double sure I'm going the right direction.

Okay, what's a lisle fan tool set? I've got a good kit but all I'm using out of it is the 36mm spanner.

X2... 5 seconds & your done!

This type of pulley holder works great:

A buddy came by this morning with a pulley-holder thing-ma-bobbee and although it was a bit too big for the Disco, with two of us we were able to make it work.

So good news, got the fan off

Bad news, the water pump ain't leaking.

I've got some pictures I'll post later but after getting everything cleaned up and all of the accessories out of the way, although I still can't clearly see the source I can tell you that it is dripping from a square extrusion at the top of the block just forward of the left side motor mount.

So I'm guessing it's the head gasket but this is my first time having to dig into the Disco and I'm not familiar with this scenario. I'm used to head gaskets leaking into cylinders, coolant in oil or oil in coolant but not external leakage like this. Is this the standard fair?

If so, then it is what it is and I'll have to deal with it unless anybody has any other ideas. The truck has close to 100k miles now so I may as well do both heads, may as well go ahead and put on a new water pump as well anyway. Is the bottom end on these engines pretty sound or should I just do the whole 9 yards?

My other vehicle is an Alfa Romeo plus I own two airplanes so I'm used to aluminum engines. My only real problem are all those pumps and hoses and contraptions in the way!
