Due to my car's 40K service - now booked in for 1st June - I decided to enquire at my VW service centre about water pumps. I read somewhere here that VW finally redesigned it to use a metal impeller instead of the weaker plastic.

My account manager didn't think there would be a new part number, he said when VW redesigns stuff, the part number stays the same but on the parts database there will be a list of previous "versions" - so just order the part and you'll get the latest revision, is what it amounted to.

So my new VW water pump arrived... I opened the box at the counter and guess what - it had a plastic impeller, already broken! To be fair the plastic didn't feel fragile and it had obviously been dropped.

Make sure you get it changed for a metal one, i have seen so many of the plastic impellers break up on tons of various cars.Ive got to order mine on tuesday, they better not mess that up because im doing it tuesday night [<:eek:)]

It's a bit late now, I've booked it in for Thursday and I have a new VW pump on the way. I'm going to let them do it using genuine VW parts throughout, at least that way if anything goes wrong there's no comeback.

A small consolation is that when I changed mine, the impellor was still plastic but a different colour to the one fitted. Think it was black plastic and the old one was white plastic or vica versa, can't really remember now. But the original one lasted 115k.

The point is, they have modified the pumps.

Yes, it's black/anthracite on the new one I saw. I'll ask them to give me back the old pump [Y]

Do you think we need a "Post your water pump impeller colour" thread?

Now I've only got to worry about the gearbox shattering due to the crappy soft rivets problem. I've bought the repair kit, just looking for a decent place to fit it that won't cost an arm and a leg.

I've also bought a spare clutch pedal, and I'm looking to get it reinforced either ready for the day mine goes pop, or fit it before that happens...

The last belt i did was on a `99 90bhp tdi golf, and i managed to get a metal impeller pump for that, not just not sure if it was genuine because i ordered various service items from gsf at the same time.Ill let you know tomorrow how i get on.

Nice to see your planning for the almost inevitable.

If you want me to mod your new clutch pedal to how it should be, give us a shout.

And, are you sure your gearbox is one of those that suffers ?

Thanks for the offer mate, how many Krispy Kremes would you like in return?

As for the gearbox, well it's the DUU code that is always mentioned for having this problem but fellow forum member w16lam had his ERT fail in the same way. I've got the ERT.

The bolts, nuts and washers all look simple enough but the box obviously has to come off and apart to get to it, that's the trick thing. In any case these bolts seem to be very tough stuff, got to be better than rivets...

Would you like me to take a nice close-up pic of the new pedal to add to your thread, so people can see exactly why they fail? I seem to recall the pics you took were post-breakage.

The water pump in my 1.8T is leaking too. Only 22k miles and still under 2 years of age. The Rocker cover gasket is leaking too.

Must ask about the metal impellor one. Simon 20valve should know.

The golf was in at a vw specialists a coupla months ago and the guy who did the work said he sees loads of 1.8t's with leaking gaskets. It's very common apparently. Is it from the right hand side of the cover as you look at the engine ?

mine is a 1.820v engine. pump changed at easter......while the cambelt was changed....my other half did it.

As you can see, the nasty tapping noise coming from my front end that developed a week prior to the job being done was this little beauty (plastic) totally failing... well, not totally. the car never overheated (well the temp sender had to be changed to) but no damage luckily.....i know other 20v owners not so lucky. My replacement through IMG Seat in Warrington was metal. it was a gunmetal colour (dark grey with metalic specs). the broken parts of the impellor were found in the bucket after all the coolant was drained!

I need to get my cam belt change (see my thread on letter from VW - early cam belt change). My question is that if the water pump is still using a plastic impeller do I bother changing it???

Someone further up commented that the latest pump is made from a different colour plastic. This sounds to me like these ones are 'fixed'.

My Water Pump recently disintegrated causing the car to overheat and have to be towed to my local garage. the replacement that they put in mine had metal impellors although I'm not 100% sure if it was sourced from VAG.

My advice would be, whenever you are changing a timing belt that drive a waterpump, metal impeller or not, change it! They are not expensive and only take a few minutes to fit, my genuine Pd pump cost ?17, it was the new black plastic one, although i wanted a metal impeller they didnt do one. Id rather change it than have the idea of an old waterpump on my mind for years.

I've recently doner mine, the old one was white plastic, the new one black plastic.

Looks like VW may have modded them.

They're still plastic though and I don't trust them not to fail. I did my cambelt and replaced with a GSF metal one. ?21.50. Qoute from Audi for, engine and rad flushing, new cambelt and waterpump was ?678.78!!!

May as well change it as the cambelt's off anyway. Would hate having to do 2 cambelt changes close to each other!!
