Default Radiator options

Upper radiator plastic fitting collapsed and is now leaking. Is there an aftermarket option with all aluminum in/outlets? Is mishimoto an option? I see denso unit on rockauto for $100 shipped but would prefer all aluminum radiator.

I would go to a local auto parts, I think the one we got at Reilly's had a life time warranty, its just easier than trying to send it in mail and waiting if something happens to it.

If you go on ebay (yes, yes, I shop on ebay.) and poke around. I looked at the ones for chevy hotrods. Measured out my current radiator and shot a little under. It will eliminate the stupid plastic overflow tank and put a radiator cap over by the power steering reservoir area and have the hoses in the same location. Its twice as thick - but thats the dang point. Will also need external trans cooler.

Its more of a coolant reservoir/ expansion tank, than an overflow tank.

The first has a radiator cap and you add coolant to the system in it, and the later the coolant has to pass out through the radiator cap into the tank.

Part number for the Koyo OEM replacement is A1304
OEM Toyota part number 16400-50021

There is absolutely no reason to go with a solid metal radiator unless it is larger one, which you really only have to upgrade if you are overheating for some reason. The metal and plastic radiators tend to last long enough

on nismo4life's build thread he fitted a nice looking supra rad I believe with minimum modification; it wasn't a drop in affair though.
