Single core radiator with A/C?

Hi All,

I have a 93 F150, 4.9L, 5 speed, 4x2, w/AC. As far as I can tell, it came with a single core radiator from the factory. The core is only about 1" thick. Shouldn't it have a dual core radiator because of the AC? It does heat up at idle with the AC on if it's hot outside. Would a dual core radiator help significantly?

Also, when my son owned this truck, the fan blade would hit the bottom of the fan shroud sometimes. So he cut about a 6" section of the shroud out on the bottom. Would this contribute to the heating problem enough to replace the shroud?

When I looked up the radiator on Kragen and Autozone, they both called for a dual core with AC. Without AC calls for a single core.

My 1985 Lariat has A/C and the factory aluminum 1" single core radiator, along with a HUGE fan shroud. Mine has never run hot, and I live in South Carolina where it has been over 100 degrees for the past month!

Condition of the fan clutch, and shroud would play more of a part in heating up at idle than number of cores in the radiator,,

If the fan shroud had been compromised that is a big part of the problem. The most common root cause of the fan hitting the shroud is collapsed engine mounts.
