Was wanting to install an aluminum radiator in my 73RS. I'm looking at Howe and Griffin but am needing suggestions. Don't want to spend a ton of money but want something that will work as advertised. What brands are recommended and how much cooler do they run?

I used the Griffin generic radiator, for under $200. The radiator itself made only a slight difference, but when I put a good set of 4th gen fans on it, it worked wonders. Now, at an idle, I can actually see it close the 180 thermostat once and a while!

Mark,

Do you have the fans thermostatically controlled? If so, what did you use?

Why do you want an aluminum radiator? A lot of them don't cool as well as a normal radiator that is desinged correctly.

I have the original style 3 core with a 16" Summit fan and adjustable thermostat. It works OK but at idle in traffic, it can creep to 220. And it makes me a little nervous to see that. I've always heard that aluminum works better and is lighter but would be willing to go with a copper/brass 4 core. It may also be that my fan is just too small.

Question

May I join in on the chat,

I have a '66 Skylark S/W four core or whatever on my car now. Same stock width. It doesn't have side mounts on it so I have it top bolted and bottom strapped in position.
Whats the chance of it cooling my 496??? And does anybody know if I can get side mounts installed on it by a good radiator shop.

Or am I wasting my time or should I spring for a four core stock wide width radiator or an aftermarket aluminum one??? All comments considered please. pdq67

I disagree with the statement that aluminum will not cool. I have used a few of them and they work great. I think the key is to move enough air accross them to disapate the heat. Going from a three core copper, to a two core aluminum made little difference, but when I added the 4th gen dual fan setup, I lost all my cooling problems. Bottom line is that I do not feel changing to aluminum will cure a problem (unless your copper is plugged), but any difference is minimal. Weight was a big factor in my choice.

Shawn, I hooked them to a switch for now. I am currently shopping for an LT1 setup, so I did not spend the money on a temp switch. Those fans move a lot of air and are well worth the install.

Hey, I just installed a Howe radiator in my car this weekend. It was quite the improvement. I had a 140 thermostat for the summer and my old radiator. Now Im going to have to bump up the temperature of my thermostat because it barely sees 140. After test driving, I could put my hand right on the radiator with out burning it.

I ordered mine from Poske Performance. Their number is 304-428-5000. It cost me $200.49 w/ shipping&handling included.

Mark,

How did you mount the 4th gen fan setup? I took some measurements a few weeks ago from one and could not come up with a good way to mount it due to the fans and shroud being pretty wide (26") in comparison to the 23" 1st gen core.

Carl, I put mine in a 3rd gen, they must be a bit wider. There is not a lot of fat to trim on those fans. I will have to look at them tonight. You may get away with trimming the edges.
