  • 3b water pump

    quick question guys , does the water pump require changing on every timing belt change ? If so where is the best place to acquire one? Cheers

    It's not actually essential but it's so much work to do the timing belt it makes sense to replace the water pump at the same time. You need to rotate the pump to do the belt anyway so there's the added risk of a leak when it gets disturbed. numerous vendors are available. I've got a metal impellar version in my 7A made by Graf which is the same as a 3B version

          The last one I got from Audi for my 3B was part no 034121004x but it had a plastic impeller. When I did engine rebuild I got this one https://www.sparepartstore24.co.uk/2286639-gk which has metal impeller and so far so good.

            As above regards the Audi one, it'll have a plastic impellor also you'll not get your surcharge back unless it's a genuine VAG pump that's returned.
            After Mikes2 recommendation I went for a Graf (from e-bay) but got a Valeo with plastic impellor ......with the car in bits on my drive it just got fitted. Beware when ordering that is all!

              I wouldn't replace the waterpump if its only done 20K. You should be able to source a new O ring seal, which is the most likely part to fail after you've disturbed it for a belt replacement.
