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.

dgeesaman 07-24-08 06:06 AM

Phew, glad I bought mine straight away.

The cavitation looks like erosion below.

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.

Six Rotors 07-26-08 12:00 PM

I just bought one,part no N3A1-15-100A, from Mazda Canada.List is $124

speedjunkie 07-26-08 02:45 PM

^You bought the whole assembly or just the water pump?

scrubolio 07-26-08 08:30 PM

update: i took apart the assembly, does come with water temp sensor, coolant cap (as you see in the pics, water pump, wp gasket, thermostat (82c)

not sure how much these parts would be from Ray

Just the water pump.It was the last one in North America.I have ordered another one just to see how long it takes to come from japan

Six Rotors 08-01-08 07:42 AM

we received our water pump this week.If anybody wants one go to your local Mazda dealer and order part no N3A1-15-100A--ask your parts guy to order it VOR(Vehicle Off Road) and you should have one in a few days.As I said list in Canada is $124.

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?

Six Rotors 08-01-08 12:10 PM

it is the standard water pump(which was supposedly not available any longer)

OK, thanks for the clarification.

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

They may have some in stock.

firball 08-20-08 05:56 AM

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 just got my RE-Medy water pump.

Per Sheldon, five more still in stock.

KaiFD3S 10-22-08 05:35 PM

^^^^Did you just get the water pump or did you have to get the whole housing and such..

shinrars2 10-22-08 08:31 PM

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.

Monkman33 10-22-08 11:59 PM

I thought it was decided that this aftermarket pump actually is worse...?
