Boris3 Posted October 29, 2018 Report Share Posted October 29, 2018 I have to replace my thermostat on the 330i and considering what to put on the "while I'm in there" list. For those that have replaced a water pump on an e46 any brand recommendations or warnings on which brands to avoid? Quote Link to comment Share on other sites More sharing options...
1 m42b32 Posted October 29, 2018 Report Share Posted October 29, 2018 I have been using the Saleri water pumps with composite propellers as they are the OEM supplier for the BMW pumps. The bearings are likely higher quality than a lot of the other aftermarket pumps and the composite impellers don't have the problems that the old plastic impellers did. They actually sound metallic if you tap on them. I put one in my e36 m3 when I redid the cooling system and had zero issues for 35k miles before I sold it. I put one on the M54 going into the e30 as well, though it hasn't done anything yet. Quote Link to comment Share on other sites More sharing options...
0 Boris3 Posted October 29, 2018 Author Report Share Posted October 29, 2018 Thanks. Typically replace the pulley as well? Quote Link to comment Share on other sites More sharing options...

I'm not totally sure on replacing them, though I don't think you need to replace it if it isn't damaged or anything (I haven't heard of failures, though I could be wrong on that). I replaced mine with ECS's aluminum pulley since the one that came with my motor was damaged, it certainly couldn't hurt. Quote Link to comment Share on other sites More sharing options...
0 jc43089 Posted October 29, 2018 Report Share Posted October 29, 2018 They are a lot more money, around 200$, for a Stewart brand one. I have bought a couple and they are really excellent. http://www.stewartwaterpumps.com/ Quote Link to comment Share on other sites More sharing options...
0 Boris3 Posted October 29, 2018 Author Report Share Posted October 29, 2018 Nice pump! $166 at BW compared to the close to $200 elsewhere. Would likely do this if tracking the e46. Quote Link to comment Share on other sites More sharing options...
0 Jdesign Posted November 9, 2018 Report Share Posted November 9, 2018 I have seen both metal and composite ones fail. Besides that 99% of those were not my car and the owners always opted for the cheap replacement. ¯\_(ツ)_/¯ I used a Saleri brand pump in my personal vehicle and never had a problem.

0 Boris3 Posted November 9, 2018 Author Report Share Posted November 9, 2018 Went ahead and ordered the Saleri along with everything else for a full refresh. Boxes of parts are here. Now just have to find the time to do it. m42b32 1 Quote Link to comment Share on other sites More sharing options...
