Auxilliary Water Pump?

[sharanthing]

Hi can anybody help me (again!) I have read other posts about what I think is the aux water pump on my 1.9tdi 2002 sharan. It is postioned to the left of the battery compartment and starts up about a minute after the engine has been started. It seems to be making a low frequency whining noise which can be felt when you hold the outer casing. Can it be dismantled and repaired/lubricated or is it a replacement pump. Does anybody know thw part number ad where I might get hold of one? Is it a straight swop or do you have to 'bleed' the cooling system after fitting.

Any help appreciated, great forum only place to get sensible answers - better than main dealers!!

... and starts up about a minute after the engine has been started.

Eh? I thought it was supposed to start only after you STOPPED the engine (or turned the key back from accessory psoition - my pump will run if you do this without actually starting the engine, eg if I turn the key to release the steering lock to let the car roll away from infront of the garage door, so I can open the garage).

 

The low-frequency noise when it is running is normal, sounds like it doesn't need replacing or servicing (no pun intended).

Thanks Ivor, mine certainly starts up about a minute or so after the engine has started and the noise stops after I turn the engine off (there is a very quiet noise after switching off but I thought this was something to do with the air con) If I waggle what I think is the aux water pump its noise chages a bit and it feels hot to touch after the engine has been running a while. Is the aux water pump about 75mm dia and about 110mm long. The noise very much like a bearing packing up. Hope this description helps.

Sounds like it's possible on its way out! if it gets very noisey or goes totally quite then it's time to replace it
