I broke a part and now I need to order another one. I don't want to order the wrong thing, so I want to know the exact part number first. And before you chime in and say 'do a search' and 'look it up yourself' and 'check the FSM or Haynes'...I've looked. Most diagrams don't even show the part I'm looking for, and the few that show it, don't give it a name or part number.

I got an 1987 GXL, (S4 NA). Above the water pump is a pipe to the coolant fill cap. That pressure cap twists into a plastic gasket housing with a small outlet/nipple that a hose connects to, which goes to the coolant overflow bottle up front. I've seen diagrams of the overflow reservoir hose coming from the center of the radiator. But for my setup, the reservoir hose connects underneath the pressure cap above the water pump. I don't know if it's because it is an NA or an S4, but I can't get the part number from anywhere. And I don't want to risk the guy at the dealership to guess either.

The little nipple broke off and the hose has a very little stub to grab on to. I've put a clamp on it but it has still popped off on 3 different occasions...not a nice thing to happen...loosing coolant.

Who knows the part number? Where else can I look?

Thanks in advance!

section 15, 15-17Y, or 15-17YA, mazda calls it a filler cap set

there are two, there is one WITH the hose nipple, which is the early one, and one that's the later one without, that superceeds to the FD aluminum part

 

Excellent!
Your FSM high-res manual is way better than the link I was using.

Thanks a bunch for the part number and the link to a better parts manual.
