I searched "Waterpump, water pump, 2nd gen water pump, 1st gen water pump, compatible parts, 2nd gen, 1st gen to 2nd gen".

No threads answered my question. Does the 2nd gen water pump fit the first gen?

I still have my NEW 2nd gen water pump and my new (to me) 1sts gen runs hot when I push it, about half way on the meter. And the reservoir fills up. after normal driving for a while everything goes back to normal.

Does the 2nd gen water pump fit the first gen?

 

no the water pump covers are different.

the whole water pump housing assembly can if you do a little work.

new water pumps are cheap, even from mazda

 

crap. thanks man. just trying to be a cheap skate. headed to the parts store.....

 

if the reservoir is always full, then its not the water pump. First, the radiator cap is not holding pressure. Secondly, if its overheating, I will check the radiator and the fan.

 

Would you look at that? Wacky will actually get off his lazy ***, come to your house, and check it for you. Altho, I'd watch him....he'll probably figure out a way to steal your car.

 

I will defend my 1st gen with life if nessasry. You can take my life, But you cant take my 1st gen!! and then I'm drawn and quatered....

 

I could have sworn you could put an fc waterpump on the 12A. Anymore input anyone?

EDIT:Opps i see what someone means now. What work is needed to get the housing to work?

 

it will fit with no issues. in fact, its even lighter than the pre-86 water pumps.

 

That's what she said.

 

so what did he say to you?? thats it??? just lick it please.

 

Sorry, but you couldn't handle me.

 

I have one from a s4. plug the third water jacket hole on the back of pump tap the front of that hole for wp stud and rock on! Its been covered many times!

 

I just did this this spring. I used a 2nd gen housing (yay! aluminum!), but I used a 1st gen water pump (which was also aluminum, a miracle). There were one or two mounting holes on the water pump that didn't match up to the housing, but I just coated it with some good sealant and haven't had any issues.

I'd guess I shaved close to ten pounds with this mod.

However, halfway on the temp gauge is about normal. But if it overheats at highway speeds, then you probably have a clogged radiator. If it overheats at idle, check the clutch on the fan. And go ahead and replace your radiator cap, they're only a few bucks and worth ten times that as preventive maintenance. Good luck...
