emunder Posted December 18, 2019 Share Posted December 18, 2019 Mine is leaking so I need to put a new rad in. Any advantage to single vs dual core? I have dealer air so not sure if that is going to be a deciding factor. Link to comment Share on other sites More sharing options...
ArdWrknTrk Posted December 18, 2019 Share Posted December 18, 2019 Twice as much area to shed heat? Not sure of your climate, but if you need AC your truck probably needs extra cooling. Not the least reason that the AC condenser is shedding its heat in front of the radiator. Link to comment Share on other sites More sharing options...
Gary Lewis Posted December 18, 2019 Share Posted December 18, 2019 The only disadvantage to a larger radiator is the initial cost, and maybe a bit longer warmup. As for type, aluminum cools almost twice as well as brass/copper from what I’ve read. Link to comment Share on other sites More sharing options...

The engine is the same, and the thermostat is not an on/off switch Link to comment Share on other sites More sharing options...

old55pete Posted December 24, 2019 Share Posted December 24, 2019 My 86 Bronco came factory with a 4 row radiator and I did have some minor heating problems with it while towing on long grades. When I rebuilt the engine, I went to a local wreking yard and measured the radiator from an F250 and found it would fit in the same space as the original one. I bought the fan shroud from the 250 and then went to the local NAPA and bought the 4 core for an F250. It was a bolt in swap using the fan shroud from the F250. The radiator from the F250 was 3 inches taller and 4 inches wider making it 23% larger and the shroud was bigger also. This cured the heating problem while towing. Just a thought if you are looking for a larger cooling capacity. Keep in mind that the shroud is as important as the radiator as it makes the fan more efficient in pulling air through the whole radiator instead of just pulling it through the center where the fan sits.

ArdWrknTrk Posted August 24, 2020 Share Posted August 24, 2020 Any recommendations for a good radiator brand? There really aren't many choices left, in a 'stockish' radiator. If you want an all welded aluminum race type I can clue you in 20 years ago I would have said Modine. But now it's just a bunch of Visteon brands if I recall Link to comment Share on other sites More sharing options...
