well im looking to put a koyo mkiv radiator with an sc300 coolant overflow tank on my sc400. but the cooling system is routed a little differently stock. so my question is...what should i do with the smaller coolant hose that comes off the motor and feeds the coolant expansion tank? should i just block it off? im not sure, so i figured id ask before hand

 

anyone have any insight?

 

what are you asking?? so you are trying to take a overflow bottle from a sc300(2jz) and put it on a sc400(1uz) engine?? i don't think that will work seeing as the 400 has a hydrofan system?

 

im trying to take a mkiv supra koyo radiator, and put it in my sc400 with dual electric fans and the sc300 coolant bottle. my question is what to do with the small coolant line that comes off the front of the 1uz(supplies the stock expansion tank)
