Radiators

Radiator went out on my 74 REPU. The shop is soldering the lower seams back together. Any idea where I can get an aftermarket (or whatever) radiator? SF area, internet?

I netted to www.radiator.com, and within a few minutes I had a quote for $109 delivered, as well as an $89 reference to the garage where I actually had the truck. Good deal!

radiators.com

Better be careful here.
I just called to double check and they do NOT have a listing for the REPU.
Only have listing for 74-77 Mazda truck
The core is the right height 13" but is way short on the width 19" (mine is about 24").
IMHO you will be receiving a smaller radiator for the B2000 or something like that. Hose connections may be in the wrong place as well. Radiator.com would NOT send me a diagram. Lame.

They just want your money.

Thanks for the info. I had the rad shop re-solder it: $125, which is OK with me. Haven't got the mechanics bill yet.

Shit, I can have one made for less than what that guy wanted. Don't get me wrong, its worth it if you're really restoring the vehicle, but I can get an all-aluminum unit and fabbt he brackets for that kind of money.

Ah, yes...

Agreed, the price of NOS restoration/factory stock will continue to be inflated at a rate exceeding that of the custom-fab build. The price of aging rarities...

So my $125 re-solder looks pretty good. The mechanic also put in a new T'stat, after market type, but I knoow the RX7 guys all say to use the OEM tstat.

Well.....

I know there's plenty of you out there that have been in it longer than I, but from an "RX-7 Guy" of 13 years, an aftermarket thermostat is okay, unless it is not for factory temp setting and/or does not have the relief (aka "jiggle") pin. Maybe the old school vehicles would be okay with a non-factory style thermostat, but it is true, the 7s don't care for them much (at least none of them that I have tried the aftermarket ones on)...

thermo

Mazda wankel engines require a "bypass" type of thermostat, the use of a non bypass thermo will usually cause an overheating problem because water is continually bypassing the radiator.

I drilled a tiny hole in the flat part of my 180º thermostat. It's the poor man's version of a jiggle pin.

Oh, I also repaired two REPU radiators that had developed small leaks in the seams where the tanks meet the cores. I have one other rad that has a huge leak 50% around the bottom tank. I'll let a radiator shop deal with it.

Just grab a centerpunch and pop a little hole to the top where the checkvalve is on the factory pieces. I've used these in my FC for years and years with nary a problem.

Huh? I just drilled the flat part where a jiggle pin would normally be on an OEM unit.

I'm not sure if that was for me or not. I wasn't responding directly to your post, I was responding to the first one. Punch/drill. THey work about the same. Depends on what I have laying around. Its cheap tin, I have a spring loaded center punch that pops a nice hole in it without much fuss.
