Thermostat recommendation.

Dan B. said

The engine is a Magnum 360 (5.9L). I just installed a new aluminium BeCool radiator. Is it possible that there was an air pocket in the radiator when I filled it after installing new? Before the new radiator the notest it got was 190', now it climbs to 210-212'.... the problem i'm having finding another thermostat is the flange dia. I need a 2.250" dia. and all i'm finding is 2.500" or smaller.

Google Stewart Components and call them. They have the size you need and make the best thermostat.

I doubt the air pocket deal.

Is the fan arrangement the same with the new radiator as it was with the old radiator.

I'll say it again...these old cars were never designed for electric fans and those shitty aluminum shrouds that do mostly nothing but block air.

Once you hit about 15-20 MPH the fan is in the way. If those electric fans and shroud are blocking air movement through the radiator, it will cause the engine temp to rise.
