Was driving down the M3 on Sat in the Anni, and all of a sudden I noticed the temp rocket up to max, then a warning alarm sounded and the word STOP in the computer came up.......Stopped on the hard shoulder, and noticed that there was actually no steam pourning......sat there for about 10 mins and turned the car back on......temp was back to normal so I coasted it for 300 yards into the service station and the temp stayed just above normal.

While having a look under the bonnet a very helpfull AA man appeared behind me asking if he could help. Even thought I wasnt a member he had a look at the car and determinded that it was more then likely the Water Pump. I joined on the spot and he towed me home.

Car is booked into a friends garage who will use VW parts only.

Now the AA man said water pumps on golfs are a common problem. Ive never heard of it before! How much is a water pump????

Not happy on a 31k mile car either!!

Yes, the impeller is made of plastic, kinda stupid! German & Swedish do a replacement pump with metal impeller, don't know who makes it or whether the pump as a whole is as good quality though (obviously the metal impeller will be more durable but I can't comment on the rest of it).

The water pump is a common fault on the mkiv. How you have missed this piece of info whilst making your 400+ posts is a mystery worthy of Scooby Doo!!!

IIRC it is the plastic impella that is the problem. Make sure the replacement pump has a metal impella. I would change the belts and tensioner as well - they have to come off to get to the pump anyway. Also ensure that all three stretch bolts are re-newed on the engine mount that needs to be taken out to reach the belts. A few guys have had their engines drop down because garages have not done this.

Im very supprised Ive missed the fault as well!!!!!! the 400 posts are only half of my "lifetime" here!!

The garage has an ex VW technician so I know they will do the job good.......Its just another receipt I can show the next owner when I finally get round to advertising her on the web.

It should give somebody some low cost trouble free motoring, she is a minter too....only 31k!

Yep.. the plastic impeller just cracks and falls to bits. They remanufacture them when they replace them too. def get a mteal impellored jobbie from gsf or similar. It's quite expensive to do so they recommend doing the cambelt with it too.

Does anyone have any feedback on these GSF water pumps, this might sound silly but I'd hate to have a super-dooper metal impeller only to find that the rest of the pump is pants (seals, bearings, general quality of construction and finish, blah... OK maybe the finish isn't really important, but I just like things to look and feel like they were made with love [:$])

Might just pop down to GSF on the A3 at lunchtime.

Saying that, I've got a GSF remanufactured starter motor (when I got it, it looked very generic and anonymous and I just asked myself, "Huh? What is this??") and it works, and sounds, just like the original [Y]

Dont say that! What do you mean "quiet expensive"????????? Anybody tell me what they paid when they had theirs done?
Well.. I had mine changed when I was having the cambelt done. ?300ish at the stealers. But that included, 'new' waterpump, cambelt, tensioners and bolts and just all the parts needed to do a cambelt and water pump. To do either process is time consuming, so you may as well do the lot if either (cambelt or pump) has gone. Anyone else care to correct me ?

I would say at least ?150 ish if you don't replace the cambelt due to the labour involved. Try a good local vw specialist and see what they quote.

I paid ?240 for cambelt tensioners and VW water pump on a diesel at a specialist. The garage I take it too uses GSF and buys from VW Parts Department so I don't know why he used the plastic impeller version over the metal one there must be a reason though

As said above you should have everything done as it would need doing at 80K? anyway

The water pump from GSF is only about ?20 I think, but, as everyone else has said, if you are changing the water pump you may as well do the whole lot (cam belt, water pump, tensioners etc). I would have thought you will be looking at anything between ?250 - ?450 depending where you get it done??

This is what I'm getting at... there's more to a pump than the impeller - how does the GSF version compare to the VW design apart from the obvious difference? Maybe there isn't a reason and your garage just did it without thinking too much, but would be interesting to know [:)]

EDIT: Well for ?20 it's probably worth getting one anyway to have a look [:)]

Well they are only abou ?35 from a dealer so ?20 from gsf is about right once you take out all the mark up associated with the dealer network.

I think the engine needs to be moved to change the waterpump as people
are always recommending that its done when the cambelt is changed.

If this is the case make absolutely sure that the garage doing the work replaces the engine mount bolts. They're 'stretch bolts' which cannot be reused.

I've heard many horror stories of engines dropping due to the bolts not being renewed.

For the cost of cambelt parts you might as well as everything has to be removed to do the job, cambelts are not just mileage specific they are age controlled as well.

IIRC Tabs needed the water pump replaced at something crazy like 17k miles !

Are you sure that there are 3 stretch bolts on the engine mounts? I had my cambelt and pump done by a VW dealer and they replaced 2 bolts. I can confirm that the water pump was an exchange item (remanufactured) and this still had the plastic impellor which is apparently the only one that VW supply but I,ve not been able to find out why they do not recommend fitting the metal ones (probably just because they are not OE). I had a good look at the water pump that came off my car at 60k and it seemed fine but think I,ll probably opt for the metal version at the next change.

There are three stretch bolts that need to be changed on the 2.0 Apk engine - my Haynes manual also shows three bolts and a little drawing of the mount - nice touch.

The issue with the water pump is really a preventative measure. Sure it may well look fine and there are those that have covered over 100k but because you need to take off all the belts etc.. to change it - and you should renew the tensioner as well - it makes sense to drop in a more reliable one when the belts are changed at 60k or four years.
