check your fuel cooler for low coolant.

It's about 1.5 inches under the cold fill range?

Whats the deal with that fuel cooler anyways?

Isn't it just engine coolant circulated through?

Can it be hacked out?

Your fuel cooler is just behind the degas bottle (itty-bitty rad.cap). It is not plumbed in with the engine coolant (same stuff though). You should see coolant in the sight glass.

Yes on its own circuit (fuel cooler) and takes the same ford gold coolant. I mentioned it since he had front end damage and the symtom of the fuel rail temp to high. Filler up and see if that helps. May take a bit to get the air worked out.

likely some air in the system. maybe give it a little time and see if it quits, otherwise you will have to purge it.
