dunno, bogs my mind too...

2-3 weeks ago they said they bought out the entire USA's stock of pumps, and were going to get some from japan. today i called them about it again and they said they could only get the pump WITH the housing (the one that the pump and the filler neck attach to)...so price went up 200 bones...

would love to get my hands on one but dunno about it now

That sounds a little ridiculous, I can't believe mazda doesn't sell the water pump for an FD anymore.

I would normally agree with that line of thinking, especially considering the effort into the aluminum jack alone...however, let's look at the plastic AST and plastic OMP lines...so I don't trust EVERYTHING on the car, haha.


Now, let me get this straight, you can't get just the pump anymore? And now instead of $235 it's $200 more now? Wouldn't it be possible for them to sell just the impeller and let us install it ourselves? OR we could send them a water pump and have them put the impeller in? Just a couple ideas.

I agree. A simple core swap system would have solved these issues.

Core exchange would definitely solve the problem.

I find it hard to believe that Mazda would stop selling a common wear item like a water pump by itself.

I called them, and I think the new impeller is from some other car's water pump, and they can no longer get the impeller by itself, but need to buy the complete unit with impeller and housing. This other housing gets thrown in the trash after they remove the impeller for installation into an RX-7 pump housing.

Why the discoloration of the housing surface exposed to coolant?

Sgtblue, it looks like a type of hard anodize.

OK. It looked like the coolant might have been way overdue and carrying alot of rust from the irons with it...and maybe aggravated the errosion issue.

I talked to them about sending them MY water pump and having them put the new impeller on it, they "hesitated" a lot and because i think they had never gotten this request before the guy went and asked and said somewhere along the lines of $225...they also stated that they did NOT like to do this because then they couldn't guarantee the quality of the part...

i did end up dropping 400+ for the part and got it, it seems as if the filler neck housing is a bit different, as in you can't change the top part (where the cap goes on) to use the FC part (which is used to delete your AST)

however it does come with a new water temp sensor, WP gasket, coolant camp, and all the bolts/clips

pics are attached.

I'm not quite following what exactly it is you ordered.

Is this just the standard water pump?

Or is it the same water pump being sold by MazMart, the Re-Medy water pump?

OK, thanks for the clarification.

BTW, that part # is $53.04 from Mazda Motorsports.

They may have some in stock.

Maybe I can help. I live in Japan and could possible track down the parts and makers if anyone has a clue to who actually makes the impeller. Is a copy of a Mercedes unit or a completely new CNC design. By the way I do this type of stuff for a living.

I'm wondering about the same thing. They just bought a bunch of OEM waterpumps off of e-bay a while back, so I wonder if they will be able to sell just the waterpump alone without the whole housing.
