Serpentine belt snapped and while replacing it i noticed the water pump pulley has excessive pay in it (it will rock back and forth). Would this indicate a breakage inside the pump?

My bad - I should have specified td4. Thanks for the trouble though. I've since found out it is the water pump pulley. I think I'm going to have to replace the complete pump rather than just the pulley.

Always wise to change the water pump if the pulley is at fault, also you may as well do the thermostat at the same time, change both belts.

Yes, thanks Arctic. I've got a replacement pump and thermostat on my donor engine, which has done less than half the miles, so I'm going to use them. I saw a video on you tube where the guy took the pump off from underneath the driver's side wheel arch. Hoping to emulate that. I'd really like to know why land rover decided to pack everything in so tight on the car. It's a few torx nuts but it is a pain to get at.
 
While it is off, check and / or replace the O ring on the coolant rail. Impossible to get off without removing pump and stat. Or rail which is harder !!

A new pump comes with a new gasket which requires the old one, if original, to be cut off as the gasket was made in one piece when engine was assembled at factory !!

Access through RH track rod hole is possible. Allow 4 hours as it's your first time !!

I likened it to delivering a calf through a letterbox when I did one this way.

Good luck.

You'll potentially regret using used parts. It a 4 hour ball achy job, so I'd only fit new parts.

Thanks for the tip. I may as well do what needs to be done while I'm there. Yes, it did look very tight in the video, but since the alternative is likely to be worse for me I am going to take my time. In fact, the chap in the video stressed the need for patience.

Thanks Nodge. You're right of course. I had a brief look and I don't think the parts are too expensive.

What's your opinion of Lucas for the water pump? I've found an original LR thermostat for not hugely more than other makes.

Use OE or genuine LR boxed parts only. Avoid aftermarket parts, as quality is often poor, and so fail rapidly. It's an unpleasant job, so needs to use parts you don't want to be replacing again soon. Also change the Torx bolts for standard head bolts whilst you're there as it gives better space for putting it back together.
