Soak it in some PB Blaster

 

it was simple I directed the flame on the nut not the blade, using a small propane tourch. But is shouldn't be that hard I only had to do that because someone put loctite on it.
You need to lock up the pully so it will not turn, I'm assuming that is your problem the pully is truning.
You can use rags to jamb the belt, you can take the belt off the idler and clamp it on the pully with visegrips, you can try and get a pair a vise grips on the shaft.
there a several ways but once you get the pully to stop turning it should break free without to much work.
You do know it is a left hand thread correct?

 

Oh, well I have a big one, and well decided not to use it because I would have probably messed up the plastic fan lol. I ended up just pulling the whole water pump off with the fan (what a b*tch) and will go from there. Thank you all for the input!

 

Wow I got this could be an easy job or very difficult. I just did mine. Shot it with pb blaster and got a kit from advanced auto. The third wack and it was off. 1 hr start to finish. Definently a DIY.

 

It was super easy on my rangie. Didn't take hardly any time at all. PIA on my Disco, but now that's behind me. The next challenge is to replacing the oil pump gears and the timing chains and sprockets. And putting it all back together lol.

 

Yeah I think that may be past my knowledge level but then again... For the money I would probably try to figure it out. Viscous fan cured my heating problem. It's always nice to get a proper diagnosis and fix! Good luck!

 

This is what I did: clamped a vice grip on the pully with the handle against the side of the alternator for leverage, put a crescent wrench on the bolt and whacked the handle with a hammer one time...worked like a charm for me last night.

 

I love the power of forums...

jfalls's method in post #2 worked like a charm.

Thanks!

 

We just replaced the fan clutch on my disco II after reassembly and filling the coolant we found this leak it seems to be a short metal pipe. This pipe has two hoses attached the upper one goes to the thermostat assembly and the lower one goes onto the waterpump. Does anyone know the name of this pipe or can you post a diagram that shows it. Thanks
