Re: Overheating 390 engine

i dont know for sure ,but that shroud might be the problem....
its so flat and close to radiator...
i have a feeling that air is only moving thru directly where fan is
especialy at higher speed...

you may want to do something simular like the one in picture i posted...
shouldent be to hard to fab......

Thinking about just leaving the fan shroud off, putting to fan directly on the radiator

No, that is the sensor for the electric fan

Re: Overheating 390 engine

Before you get crazy with spending a ton of cash on fans, radiators, or with people suggesting cracked heads:
Double check the coolant temperature.
Electrical gauges need to be referenced to a master guage, and even manual coolant temp gauges can be off.

good luck!

Mine comes on at 185, goes off at 170, worked fairly good when i had the 160 thermostat in. Never shuts off with the 180
