Using a 250R radiator in a 300

dino74 · September 5th, 2013, 03:28 PM

The mounting bolts line up. Left:300 Right:250

Main differences:

1: 250 thermo-sensor is on the radiator while the 300's by the thermostat.
2: 250 fan is there metal legged, 300 is four plastic legs.

But is mounts and seems to work fine.

Got a weight difference? Why'd ya do it?? Looks like you could shed some weight with a 250 fan on a 300 radiator

I think you should put the shroud back on it as the one without shroud have the rubber thingy to disperse heat from the cylinder head.

This mods is a good solution for me since i had a Koso gauge in mine, so i had to control the temp signal to the ECU manually.
