New Water pump brand options
Hey guys, got my motor rebuild and need a new water pump. Anyone recommend any specific brand?
rockauto has us motor works at a decent price with all the gaskets needed. The fins are a bit different.
warranty says 12months but also says limited lifetime warranty.

with that one you need to put your pulley on it, and sometimes you need to grind one of those ribs..
Mazda pumps are available, but not in the USA, so you need to use a Japanese vendor

I found a picture of the Japanese made water pump and look identical to the one i have.
I think im going to run the same pump. Just clean it up and maybe paint it to prevent rust.
Would it be best for me to rebuild this one it gives out. I have a spare that looks identical in case it does wear out.

You can use the spare one you have but sometimes if they have set dry for a long time they don't last very long before they start leaking from the weep hole. The seals inside dry out and on't last long once put back in service. As for a new pump I had been running Remans from O'rielly and using the lifetime warranty when they failed typically somewhere between 50 and 100k miles. They don't have remans anymore so Iguess I'll be buying a new one next time as well.

I went over and glanced at Rockauto. If it were me I think I'd just get the cheapest one with a lifetime warranty which looks to be the Gates.

I've been running the original Mazda water pump in my S5 for the past 32 years or 370k+ miles without any issues. I would suspect, given the poor quality of replacement parts these days, nothing would match the service lifetime of my original pump.

lifetime limited warranty on their mechanical pumps. I dont like that the fins are slightly different. I wonder if it will still cool the same or maybe press out the fins and replace with the original fins. It does look new and not remanufactured.

So, how do your water pumps usually fail? Bad bearing? Leaky seal?

so the seal is B630-15-120 and its available in Japan (notice a pattern? Mazda USA's parts side has no parts). the bearing isn't available, so if its bad you are SOL.
