Radiator R&R and upgrade, OEM + ?
My rad in my 90 c1500 pos/project took a dive.....I eventually want to swap to an LS 5.3/6.0 -4l80e, it has a 4.3 5spd in it now.
I was wondering what would be the way to go on replacing the leaking rad with something that I could use on both the 4.3 for now and still be adequate for the eventual LS/Auto? Is there an OEM solution, 454 rad,5.7 vortec years, 2500+ radiator, etc etc etc? I've read horror stories about the cheap full aluminium one of ebay and the like, and the plastic china replicas breaking at the upper bung/hose on the tank. TIA |

The cores are different widths between the ranks. You can go bigger, but you’ll need a fan shroud that will fit the core of the radiator, and the cooling fan.

I've replaced several V6 GM trucks with one I got from Oriellys for like $100. Never had an issue with anything on them. For that Price I would just replace it, and work out the detials later for what will work whent you engine swap.

Ranks should be tanks in my last post.

Upgrade to the biggest oem one you can fit. I put the 4 row oem style autozone lifetime warranty one in my 98 to replace the 2 row and I literally can't get it to go 10* over the thermostat opening temp in AZ 118* heat in traffic. Bigger is better in this case.

I installed an O'reilly's factory replacement about 4K miles ago. So far so good. As said above, it's relatively cheap and works. Worry about the LS radiator when you get there.
