Universal aluminum radiator question
Universal aluminum radiator question
My radiator mounts broke off my radiator, so I'm thinking of picking up one of the Summit aluminum radiators.
My question is, where do I run the lower coolant return line from the heater core to? Do I need to get a fitting welded in to the lower bung on the radiator? Is there a fitting you guys use? It boggles the mind.

you have 3 choices.
1. no heater!
2. have a hose barb put into the new lower hose thing on the new radiator. its simple, but its prolly a weld in
3. find a hose barb and a pipe and put that into the lower radiator hose. ive done this before, works great, parts come from the plumbing dept of the hardware store

bass/copper works better than AL, AL is lighter and cheaper. the stock radiator is also sized well and hey its already there...
in this case stock is really good.
the 83-85 radiators are actually larger than the competition radiator they used to sell back in the day

My radiator could use serious replacement anyway... it's getting pretty "green". Plus I would like to lighten up the front end (my goal is to shave 150lbs off the car).
That, and those Summit radiators are pretty cheap...

Larger but only a 2 core design.
Because, oddly enough, sometimes they are the best parts.

we just had a thread that covered this. there are a couple on ebay for decent prices that are for the most part bolt in replacements.. i was going to use universal one but it was worth the bs.
We'll see. I have until Thursday to make a real decision. I need to do something soon though, have a 3-hour road trip coming up in 2-1/2 weeks... and I'd like to take the RX7 (not necessary if not possible, but seeing as how I'm going to meet up with other RX7 owners, I'd like to bring mine along instead of something boring...)
