hit a brick mailbox and got my truck back from the shop today with a new bumper replacement on it and with regular driving my eft1 was up to 150 degrees!
it was 89 degrees outside and im on the 250 egr tune


do you think they could have installed something wrong?intercooler?

thanks!

 

check your fuel cooler for low coolant.

 

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

 

Hi 6.4PSD, I'm going to move this to the 6.4L Powerstroke forum.

 

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.

 

filled it up and am now getting a howling sound which seems to be coming from the fan or something near it???

 

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

 

Ok thanks for the help

 

did you ever figure out a solution to this problem, or a cause of it?
