Risky statements coming -Plastic is technically a better thermal conductor than even aluminum. The reason most say stay away is because it's more prone to crack and leak at the mating surface than it's all metal (and welded) counterparts. No doubt in an idi's case it's true.
At this point though,the first run of super dutys left the line over 20 years ago today, and some still have the o.e plastic tank radiators. I don't think it's nessisaily the plastic that's the problem, it's the aftermarket manufacturer that's always the problem. They can be made even better than the original copper brass units were in every way (efficiency,weight, reliability, serviceability) they just flat.....aren't......
