dunk1 Report post Posted October 22, 2019 Anyone replaced the plastic water pump pulley for an aluminium version ? Any recommendations I've found a very nice one but £50 with the postage is a tad steep as i'm not to fussed about it being motorsport derived https://mp-uk.com/bmw/3-series/e46-1998-to-2003/ecs-tuning-aluminum-water-pump-pulley-e36-e46/ Quote Share this post Link to post Share on other sites

Don't use Circoli from Eurocarparts. Absolute crap. Kirkynut I've bought the OE water pump, this thread was to replace the plastic pulley the belt runs on that fits onto the water pump Edited November 2, 2019 by dunk1 Quote Share this post Link to post Share on other sites

kirkynut Report post Posted November 2, 2019 Sorry, I realised that you were talking about the pulley and not the impeller after posting and edited it immediately but you beat my edit. What's wrong with the plastic pulley. Once you have had it off once and didn't break it, pop grease where it mounts and it will always come off ok again. I've done a few now without issue.
