Hope I can get it sorted as we are heading off in two weeks.

I have only just discovered this site and hope to be a regular visitor.

Thanks again

1. Doesn't surprise me. I did the PAS and water pump on mine a while ago. Took me all day Saturday. The amount of stuff that has to removed and replaced to get to the actual units takes time. Lots of it!

2. Get it fixed then, or, at least satisfy yourself it doesn't present a breakdown problem.

3. It's a great site with tons of info. and experts.

4. You're welcome!

I have only had the car for 18months and it came with a warranty. The only catch was I have to take it to their repairer so I thought I may as well save some money.

I picked it up last week and have not driven it a lot but I thought I could hear a different noise. I know the bloody thing far too well.

So when I took it in to get the bull bar this morning one of the blokes at ARB in Newcastle has Disco himself so asked him to listen and he mentioned belt and/or bearing. So looks like you are on the money.

Hope I can get it sorted as we are heading off in two weeks.

I would also check the exhaust manifold and exhaust gaskets either side of the turbo for leaking. They may have removed your turbo to allow a bit more space to get at the centrifuge and waterpump housing (centrifuge has to come out and when i did my waterpump i had the turbo out also as it makes everything a bit easier). If they re-used your exhaust gaskets they could well be leaking.
Also, if your exhaust manifold has warped (common Td5 ailment) you will have some broken exhaust studs. This causes a sound when driving that could be mistaken for a belt or bearing noise. Have a look under your turbo heat shield (using a torch) at the studs on exhaust port #5 to check if the studs and nuts are still in place.
If it took them all day to do might they have removed the exhaust manifold also??

You are kidding! Surely, you are kidding! Remove the turbo, exhaust manifold and centrifuge to change the water pump????

God help us!

This is a joke! Right?

Ok, Muzz here is what I hope is the end result. Took it in today and they remvoed the main belt and inspected the idler bearing and deemed it to be ok. They the cleaned the grooves in the maint belt drive and it now seems to have no noise.

Hopefully its sorted....:D

Hi Mark, good to see you have the problem sorted, i'd put a new belt on just to be sure.
Have a good one.
Good to see you found the place(I'm the bloke at ARB)

Try squirting the belt with CRC first (where it makes contact with the pulleys).
If it doesn't make any difference, try directing the squirt at the bearing itself.
Any variation in the volume or frequency of the noise will tell you lots!
P.S. Don't go nuts with the CRC!

I found that the drive belt had some goo on it, so I scrubbed it in soappy water. It looked fine and when I put it back in there was no noise - for a while - then the squeal returned! Then I squirted a fine jet of water and the belt went silent.

Is there some specialised lubricant for belts?
Can you lubricate a belt with CRC permanently?

Thanks, Nigel

All i'm saying is that if they are unfamiliar with the vehicle they may have removed more than necessary to access the waterpump, this would account for the extra time taken. The centrifuge has to come out to get the waterpump out, a bit fiddly but not hard.

Still worth checking the exhaust manifold for broken studs thou....

Just to throw a strange one into the mix, if when they took out the centrifugal filter they replaced the filter it may be rubbing inside the housing. A while back I had a service done and an after market centrifugal filter was installed that was too tall and started to rub the housing. Was a bugger to find as I thought it was a pulley or belt. Easy to diagnose as the wear marks were on the top of the filter after taking off the cap.

About an hour to do the Td5 pump, a little longer if it has ACE,and about another 30 minutes or so if the system needs a thorough flush etc.

I remove the A/C support / waterpump/ PAS bracket from the block and replace the Oring aswell.

All day sounds like a problem was encountered, but if you weren't paying for it alls good!
