Go water pump, please help. -UPDATE-

Post by oscarloco »

Well, my water pump is officialy dead. It hasn't seized yet but it's whirring awfully, every day gets worse.
I just bought a new one and this weekend it's replacement time. I also ordered my Haynes BOL but unfortunately I have to wait another 2 weeks for delivery.
After reading all that can get damaged due to a water pump seizure, I know it has to be replaced ASAP.
Could somebody give tell me how can I replace it, what steps do I have to follow and what are the pitfalls.
Thanks.
Richard Green

should be a very easy one mate, its only the 8 valve so you need to line the top and bottom up "TDC" to remove the timing belt "you can use a 10mm drill bit" to lock the top cam and the same for the crank pulley, I would change the timing belt since your going that far if it needs it.

Cant really add to Richard's advice.
But the job is exactly the same as replacing the cambelt - as this has to be removed.
You may try if this write up is any help to you : Replacing cambelt
In any case : we are here in the weekends too [:)]

I could also snap a picture from my book if you have a problem.

Can someone describe what a whirring water pump sounds like ?
We'll be doing the cam belt on my Dad's Xantia soon (2.0 litre 8 valve) but there is what I would describe as a whirring noise which gets quieter after a few minutes running, but whose location can't easily be identified.
I thought it might be one of the bearings on one of the tensioners/pulleys on the aux belt, or maybe even something to do with the air conditioning pump (as the air-con is out of gas) but the thought of it possibly being the water pump worries me. The engine has done about 150,000Km. (not miles [:D])
Any suggestions to identify the noise ?
Regards,
Simon

Stick a screwdriver (or engine stethascope)between your ear and the timing belt cover.
Mine was rubbing down the bottom where the pulley sits. Might be a good starting point.

Thank you so much for the help.
With the timing belt, no problem, I replaced it in december (when the "Citroen specialist" almost killed my car)
Richard, thanks for the pictures.

I do my best to save money, so you only need to lock the belt off and change the pump its a simple job but get a new seal for the water pump and make sure the faces are clean from old gasket, at this time you can rotate the tensioner to see if it rumbles as if the bearings are worn but it should be ok on your car because it had a revision on the tensioner

That's exactly how it is, the sound seems to be coming from everywhere. In the begining I thought it was the oil pump but then I noticed that my car was leaking water from the pulley side. Only the water pump.
Try removing the accesory belt just to be sure it isn't the belt tensioner or A/C and turn on the engine, if noise continues then water pump or cambelt tensioners are the suspects.

Had an appalling noise from my TD BX on holiday last year - what with that and a slow hydraulic leak I thought the time for replacement with something very heavy and slow was looming (Xantia Estate). Turned out to be alternator drive belt - so don't jump to conclusions.
I have had this before on a Renault 21 and both times I have found a squirt of silicon spray or even WD40 will quieted it for a while which is good enough for diagnostic purposes.

Operation Water Pump status:
Success with a scare.
After reading and memorizing Anders Relative Indexing method and sutdying Richard's pictures of his Haynes BOL, I started the replacement of the pump yesterday at 10 am.
In the beginning all went according to the plan. Finally I got to the pump, removed it and replaced. Then re-installed the timing belt, checked markings and following Anders paper, fitted the damper temporarily and turned the engine a couple of revs with the tensioner loose (my car has an eccentric tensioner).
Then disaster struck, in the first revolution I saw the belt jump a couple of tooths on the water pump sprocket. The Horror as I didn't know if it had jumped in the camshaft also.
So, I removed the spark plugs (to be able to turn the engine easier) an turned the engine backwards to where I started. Removed the belt and installed it according to the markings. Everything seemed OK but I didn't want to risk it. So I aligned the timing marks just to verify everything. By this time, my father came to help me (maybe it was all the swearing or the sweating that hinted him to help me).
I got some pictures of the peugeotworkshop site and I looked fine. There I learned that the camshaft timing mark is not at TDC, rather at halfway point of the pistons stroke and since the damper can't be trusted, the keyway has to be aligned with some screws in the block.
Everything was OK, the belt had not jumped in the camshaft. I was so relieved but still, the final test, turning it on. First I checked thru the sparkplug holes that the pistons weren't striking the inlet valves. Then turned the engine 4 revs by hand to ensure all the pistons had gone thru their cycle without collisions and then, turned the engine.
Everything worked fine! I was so relieved and also felt very proud of myself.
Thanks Anders and Richard for their help. I would only add in Anders method to tension the belt a little to avoid that kind of scares. Believe me, I am now 10 years older because of that.

Well done!
When using the Relative Indexing method, it's a good idea to mark the pulleys and belt together, so that if anything happens to cast doubt on the timing, you can check it easily.
