Sure. I'm pre turbo. The electric water pump is undoubtedly better for long term, but had initial issues (on the other hand, it has a clear engine code and is easier to access)
- mulmen 5y agoI have a 2010 BMW 335, which is twin turbocharged. It is on electric water pump #3 in less than 100k miles. My mechanic tells me not to worry about coolant change intervals because these water pumps will never last that long anyway. The electric pump is great from a performance/efficiency perspective because the car can make choices about coolant temp irrespective of engine speed. It's a horrible device from a reliability perspective though. I have already been stranded by it once. My turbos are "fine". But I know they will fail in the next 30k miles. In talking to my mechanic the prices fluctuate quite a bit, so I am going to start keeping an eye out and just buy a pair to have on hand when mine finally let go.
- smileysteve 5y agoThe previous owner of mine installed a new water pump at 80k miles, and I did it again at 150k. Similarly don't have to change the coolant because the coolant expansion tank will break in 5 years time. (the corner is plastic and can't take the pressure.
