4th gen BB4 radiator capacity

Post by **vanzep** » Tue Apr 29, 2014 11:59 am

Just wondering if anyone knows what the coolant capacity of an oem jdm radiator for a BB4
Im fairly sure that the BB4 had a different thickness of radiator - think it was a toyo 32mm thick core - this is the one that i need the coolant capcity of. I know the aftermarket 16mm thick core ones hold 2 litres of coolant and want to compare it against the 32mm core.

Is it logical to assume it will be at least 4 litres if it's double the thickness?

You would think so but its not correct - although it will be a larger cooling capacity

I have two radiators here 16mm (manual) core one holds 2 litres and the 32mm (auto or manual) one holds 2.2 litres

The technical spec in the service manual isnt much help. It only states complete capacity inc the block, hoses, expansion tank etc...
