Water Pump

[swanny1970]

Hi All

 

Just a question about the water pump if anyone can help please. When I start the car up, there is a knocking/grinding/whirring noise coming from the area that the water pump is in. Now, I have no leak, but after about two or three minutes of driving, the car will hesitate, stumble and after about 40 seconds it 90% corrects itself. I was wondering if the thermostat could be not opening when it should and this stumbling of the engine is because water is not circulating as needed? Once it has more or less corrected itself, the car drives without a noise for the majority of time. Any help would be greatly appreciated please.

 

Thanks in advance,

 

Kind regards

Sounds like water pump, but you wouldnt get a knocking noise from it. id get your car into a local trusted garage for an inspection post hast.

if the impellor had come off (problem with early plastic impellor) would it clunk around?

Hi, when mine went on our 52 tdi (115), there was no sound - the impeller had come off.

 

BTW; is the pump covered by a lifetime guarantee?

 

Thanks

Thanks for the info, think I will take it round to the local garage for them to have a quick look. It sounds as if something is struggling to turn when the engine is cold and as it is coming from the area that the water pump is, thought it may have been that. Could it be that the bearings have gone inside or would I get a leak if that had happened. I don't know about a lifetime guarantee sorry, bought mine pre-owned.

 

Thanks again

 

Kind regards, Peter

Do you have air-con? If so it is possibly the bearings in the clutch pully failing.

No the pump is not covered by a lifetime guarantee

 

If it goes (i.e impellor falls off) expect to pay around
