My stock radiator is starting to spring some leaks and wanted to know how the aftermarket radiators that are plastic/composite on the top and bottom work. I know the newer cars have these types of radiators and just want to know if anyone here is running these and if you have any issues. Can't be too bad because they have lifetime replacement

 

They are pretty stout. Ive had them in numerous cars and trucks, also if they do break they can basically be plastic welded back together (for instance you buy a used one over new) Best bet and its kinda overkil is buy an all aluminum like a KOYO and get the FAL fans or use a fan from a ford taurus and you will never have any overheating issues for life.

 

lol i had a few of those plastic endtank radiators go out on my 3VZ-FE V6 1993 Camry

luckily, autozone had a lifetime warranty
