Blew my radiator. Found a few aluminum radiators for my 4.8 but say theyre for an auto trans. Can I cap those off and run it on my 5 speed or am i S.O.L. and have to get an o.e.m. Not too fond of those plastic tanks

 

Yes you can cap them, but you will loose some of the coolant level volume do to the cooler. you cold use it as an engine cooler...... your truck has one of those, right?

 

ya u can just cap em off..
cheapest all aluminum radiators that iv seen is genesisautoparts dot com

 

Or you can leave them open, nothing will come out.
