fj40 4 core radiator

[Stroker]

Hey guys I bought what I think is a new 4 core radiator from a guy and I'm curious to know if there is a way by looking to know if it is a 4 core for sure. The reason I ask is it feels some what lighter then my original radiator although it looks the same.

Count the cores....They line up front to back between the fins...look at it, you will get it..


Good luck!
