it's got some pin hole leaks (some on seams, some not on seams) on the upper tank.
and, it just will not keep up to 115* ambient temps, and scorching pavement traffic situations.
There's a really good rad repair shop down the street from work, I'll give them a call and see about $$$ and time they need to keep it.

Yeah Faithful Old Dog, I run a Howe Alum. rad. in my Jeep and it is a trail only rig, which means little to no forced air flow and pushed to the max. It really gets a work out and is a vast improvement over the stock rad.
Clean LX check out Howe's, they were pretty cheap and good quality (all welded alum. not epoxyed). The only thing I didn't like was the lack of a drain valve, but I had one tig'ed it with a bung and it works great. I got it at Summit Racing.

My local radiator shop got me a "new" replacement 4 core for $157 !!!
I replaced mine last fall when it seemed to get too hot anymore. It was down 30% on flow so I just bought a new one. For that money it was not worth doing anything else. He had it on stock, so it must be a common unit.

I picked up a heavy duty radiator (3 or 4 row; I forget) from Performance Radiator (I guess they are franchised) a number of years ago at a pretty reasonable price. I haven't been disappointed yet. My cooling system capacity is now about 4.5 gallons.

I'd consider switching over to a newer radiator like the ones found in the newer trucks (1980 and up). I'm planning to do the switch on my '79 once the weather breaks and I do my engine swap. Up on the top right hand corner of the page here under Tech Articles there is a piece explaining why the cross flow radiators are more efficient than what originally came in these trucks. Makes sense to me!

mine is water in on the top passengerside, water out on bottom drivers side... that is crossflow right?
I see in that article, we are sponsored by radiator.com...
So, Samsung must be a good rad?
I mention this site, and get discount?
How's it work?

cleanLX,
I purchased a radiator from radiator.com and it has ran without any problems for four years. I used it the Tucson area for 2 of those years, not quite as hot as Phoenix area but still a Pizza Oven!

The crossflow radiators have the cores running horizontally, with the tanks on the sides. This era of trucks came with the downflow radiators. I guess the crossflow is more efficient. You'll have to look and see if the cores run horizontally or vertically. Possibly someone has already done it, seems like a good upgrade to me!
