CJ v8 Radiator Question-Purchase

Jr needs a new rad for his CJ w/a 360. 3 cores are around 350.00

I found this (200.00-2 core)(link below) and Summit sells one w/1" tubes for 350.00.

Is this good enough for him to wheel with ?

I have never owned an aluminum rad so I don't know anything about them.

Thanks,
Jim

I had an aluminum radiator in my 70 3/4 ton and a 396,that was flawless.I think it was a Griffin.

My 86 CJ7 has a 350tbi with a 2 core from the original 6 cylinder. NO problems so far,with 2500 miles of use and light offroading

Aluminium is cheap but does not conduct as well as copper. It may work well but only because it has hot water flowing through it, not because it is an especially good radiator design.

Have you taken the old one to a radiator specialist to have it recored? The OEM copper / brass type material radiator is a better radiator.

Jim,

I went with the Champion 3-row aluminum radiator on my 360.

It's worked fine, so far.

Advance carries a 3 core for $180 - look up '78 cj7 with 304/auto and a/c. I put one of those in my cj7 with 360 and I had to cover part of it in cold weather or the engine wouldn't get warm enough.

On my '78 I lucked into a new in box 3 row downtube copper/brass for free from a friend that went another way with his Chevy conversion. Once I coupled this with a Contour/Mystique dual fan assy. did the trick on my 360.

Thank you all/will chack out links/info-no I haven't tried Advanced.

I did ordered one from AZ but the guy couldn't tell me (of course right) if it was 2 or 3 core. I run 3 core in all mine but out here there is nothing and no place to recore it unless you send it off.

Didn't know aluminium was not as good as copper.

I will pass this on to my son and maybe my mistake was not telling them it was w/A/C.

Thanks for the pics Matt=sweet !

I wouldn't go that far.

This thread explains the pros and cons, well.

Radiator

Been replacing radiatiors for some time when younger. And found out this

2 core while cheaper will work on smaller engines well, like a six cylinder and a small v8.

3 core is made for mid size engines like a 350, 400

4 core made for big engines like a 427, 455

Now granted that they will interchange but, you will run into higher temps with a small radiator on a large engine. These can be adjusted with the proper thermostat. But will take some study time to achieve your desired temp range
My view is if I reach 250 degrees something's wrong. Most cars will run around 200 give or take 15 degrees.
I do know that alum. Sucks heat very fast an they r used in heat sinks, often without water.
Being in New Mexico and the heat we have in the south I would stick to this scale, I would want to remain cool as I could. Not so much for road driving as it takes care of itself, but off road you don't have the constant velocity of wind to help cooling so u are relying on the fan, and rad. size to keep temps down. Also when off road it is smart to keep shroud on, though not required, is a help as it pulls more cool air rather than mixing cool air and hot engine air.

Also on a side note, when younger I lived up north and would take out thermostat in summer, and replace in winter since your heater temp. Is directly related to your water temp. If left out in winter it would remain to cool to provide sufficient heat.

When I lived in Fla I did not run a T-stat. I run 195 in my 360 now and I put 185 in the kids 360/304.

My mechanical gauge reads almost 200 w/out the electric pusher fan for summer and 185-190 w/the pusher fan.

Might drop down to 180.
