how to fix? maybe a bolt held by exhaust clamp. if it broke on this one, likely it will break on the good one on my car

 

I bought the one currently on my car in 2005

 

 

lame, i guess you cold weld a little piece on there, and drill and tap a new hole. find an S4 FC pump, its the same, but aluminum

 

Ya I am not sure that is worth fixing.

Depending on what your doing on the car...

You are going to want to install new OEM gaskets, thermostat, maybe replace the hoses... by that point putting that piece back in would just seem like a step backwards.

If you are in a bind to get the car going soon, you could probably weld in a short piece of steel threaded rod and use the corresponding nut on that side. Align stud before welding by using your thermostat housing/neck for temporary alignment.

 

"what I plan on doing with the car?" <---<<<it's my daily driver.

That one broke 16 years ago when I was putting a rebuilt engine in. I'm worried that the good one that is on the car now will break also if/when I have to change the thermostat.

Or no other rx-7 thermostat flange has broken like that, and this is a fluke?

Last night I changed the clutch hydraulics, because the clutch was starting to feel weird. $30 in parts, and a couple of days because I used rust reformer on the local rested areas. In 1993, the shyster mazda dealer in Hawthorne (Los Angeles) sold me a leaky one, I tried to return it, and they closed that location.

 

i can't say i have seen another one

 

MM if you want a spare water pump housing I can send you one if you pay the shipping, I have several.

 

ray green, thankyou , where are you? you have a karman ghia? cool ! it was in KILL BILL ! !

 

I wish I had a karman ghia, along with the 1st gen RX-7's one of the prettiest cars ever designed.

But no, you may be thinking about James over in South Carolina, he's got a blue one he recently restored.



I'm in Jefferson Georgia, a couple hours from Huntsville but only an hour away from DGRR.

That housing is heavy, if you're ever in the Atlanta area we may be able to arrange a pickup.

 

yep, that's beautiful.
