tbh if you are asking then it's best you take it to a garage. I don't do the big jobs myself I use www.powerfiat.co.uk. Top lads and will do your cambelt and tensioners as well as the waterpump for £399 all in. If you're a BOO member make sure you mention it and your membership number or they may not book you in (very busy bunnies) and you should get a little discount too.
If you're not a BOO member - WHY NOT!!! IT'S ONLY A FIVER!!! lol!
you need to loosen off the engine mounts (while supporting engine) and shift the engine over a few inches to get enough clearance to get the waterpump off.
i havent done this myself, but i know its not for the faint hearted.

errr ok im gonna pass on that one lol!
If the water pump was on its way out would i get a fairly high pitched noise from the engine all the time or only when running over 2-3000rpm?
water pump bearing failure can happen in 2 different ways, seizing or collapse. collapse is very nasty, very rare, and obviously not an issue here. when the bearing starts to seize you get a constant whining from it, which is usually worse when hot, and increases in pitch and volume with the rpm. the noise indicates excess friction in the bearing which means excess heat will also be occuring. if the bearing overheats too much it collapses. i'm already praying that wont happen but if you suddenly notice a change in the noise be afraid. when the bearing collapses the timing belt can go slack and slip or catch on something and snap. not good.

i dont suppose theres an easy way of finding out if it is the water pump i can hear? any tell tail signs of a pump failure? ive got normal temps and no loss of power. kind of hard to hear exactly where its coming from but its def on the water pump side and its def engine related and not wheel bearing or brakes.
the same noise will occur on any of the driven pulleys if there is a bearing issue, take your pick from PAS pump, alternator, oil pump, water pump, tensioners, idlers, basically anything that either of the belts is turning. the best way to identify which one is to remove the belts and then manually turn each pulley seperately to feel for roughness or play. not great i know but thats how you do it. the other option is my patented hosepipe method. stick a bot of hosepipe in your ear, and hold the other end near each pulley in turn with engine running. you will then be able to pinpoint the noise (with a bit of luck)

Loving that!
Besty - when was your last cambelt change? may be best to get the lot done at the same time to be sure. tbh, the HGT does have a high pitch noise as standard. Everyone that has one says the same. I had cambelt with water pump change 40k ago and the noise was exactly the same after and every HGT I've heard is the same.

My cambelt was changed at 53k about a month ago, its not a very loud noise if ive got the heater going i cant hear it so i guess im gonna leave it and worry about it if it gets louder
and no i didnt get the water pump done and the same time and yes im regretting that now

D'oh!! Well if you get yourself to the AI meet at Brooklands there will be a number of HGTs there (including mine) so you could compare the sounds you are hearing.
I had my HGT MOT'd on Monday and I was informed of a tensioner on its way out.
I popped into Solo Italia later that day as I was going past them on my way to Sibford and I asked one of the guys there to have a listen.
He thinks that it might possibly be my PAS tensioner starting to wear.
I have a slight whining noise when going through the rev range and until it was pointed out to me during the MOT I just assumed that it was a normal whining noise (something that the 5pot does)
The previous owner had the cambelt changed about 20k miles ago (changed at 42k.... now on 60k) but I dont know if they had anything else replaced at the same time (other than clutch) because the invoice just states "Cambelt and Clutch Replacement".
Ozric - I might have to see if that offer extends to me at Brooklands because I would like to put my mind at ease.

Can a pas tensioner etc be changed without a full cambelt change? ive had that done twice in the past year and i cant justify the outlay despite the fact that i love the car!
There must be an underlying cause.... what were the reasons for failure the last 2 times?
PAS pump is driven by the aux belt, so changing the tensioner for the aux belt does not require a timing belt change, it is something you can do yourself easily. the PAS pump does not have a tensioner of its own, the only tensioner is the spring loaded aux belt tensioner.
I have been reading this tread with a lot of interest as I am having a similar problem with my 97 Bravo HGT. I have developed a squeal from aux belt/water pump area once the engine has warmed up. Its most noticable when idling and rises in pitch with the revs until about 3k rpm when its downed out by the engine noise. The car has done 65k and cambelt was apparently done by the previous owner at 42k but I have no idea if the other belts and water pump were changed too. My local mechanic reckons that its due to noisy "idlers" and quoted me 2 new idlers at £50 each and half an hours labour. Does this sound likely or should I just put the hundred-odd quid towards a full cam belt etc change with powerfiat for £400? Thanks in advance for any advice.
if the idlers are making the noise, and the belt was definately changed at 42k (receipt proof?), then it would be a waste of money going to powerfiat and you might as well get the idlers changed.
but if it turns out the noise isnt the idlers what would you do?
if you cant be sure about the belt change, then you should get the belt and idlers changed, but you may then find the noise is still there if it isnt the idlers.
