Hey guys I'm new to this web site and I need a little help with the intercooler pump of my 2003 F150 lightning im not sure if the pump is burn it has a Bosh pump allready I bought the truck use with 68000 on the odometer,any tips will help.I try to play with the pump and the connection to the pump to make it work steady with the engine running, because it was on and off ,but I can't make it work steady.

 

The pump turns off and on dependant on the temperature of the coolant in the intercooler.

 

Thanks JollyGiant I was about to go online to get another intercooler pump because I was not sure if the pump should be running at all time (with engine running)Thank you very much!

 

The intercooler pump is supposed to come at a lower intake temp of about 62 degrees. I've found that it usually takes a few minutes in the summer (longer in the winter) for the temps to rise to that in the lower intake - and the pump will be actuated by the PCM. Once at that point, with the engine running, it should run continuously. When I drive my L in the summer and it's fully warmed up and then shut it down - and start it back up a little later, usually the pump then comes on immediately.
