and after a few days of search, McGuyVer manage to get his hand on a 3-layer dual speed radiator with fan.
see the size of the fan's motor. and the size of the radiator is slightly bigger as well.
that's what we were talking about ^.^ 3-layer versus 1 layer.
install new radiator rack, the original piece is all worn and "torn".





after installed with 3 bottle of Toyota Coolant, and 3.5L of water! (it's a BIG-A** water tank) water temp was well keep below 90 degree Celsius, and yet, we discover the water-valve is not working properly, the water temp will drop well below 70 degree when cruising at normal RPM. more thing to do T_T...
