Question radiators with/without EOC.'s

Weekend mechanics here trying to save a few bucks we can't spare. We bought a radiator for our '92 Chevy c1000 p/u. The parts store had their inventory marked wrong and sold us one with an EOC but was supposed to be without. We don't think our truck needs the EOC one. The clerk at the same chain but different location said it doesn't matter, they're all the same anyway and just leave the plastic plugs and it'll work just fine. Why then is there a choice and a price difference for one with and one without the EOC? Is this true are they the same more or less and nothing will happen with the plastic plugs? They won't melt or blow out, we're just not convinced enough to be comfortable about it. Thanks for any insight.

i assume you mean the auto trans cooler? if that is the case, you can just leave the plugs in the holes, as it is a sealed away from the anti-freeze.

eoc radiator

right nightowl it is an engine oil cooler located on the right side of the radiator if you're sitting in the truck, my sub '92 has it.
i dont think it would make any difference in this case since your truck doesnt have the eoc system,just keep the plugs on the rad, the eoc works by running the engine oil thru the rad to cool it off but it never comes in contact with enything else at any point inside the rad so it should fine.
more info if needed : rebuilt radiators go for $ 130.00 in my city, 34" wide by 18" tall by 2 1/4" thick core for the 5.7L 350.
pressure checked with a six month warranty.

assuming your truck actually doesn't have the eoc system. if it does it will have two lines similar to the transmission lines but the thread is smaller and they're on the opposite side.
