Low coolant

[GnFnRs]

today i noticed that the heater in my truck wasn't getting hot. i checked the coolant level and it was low...took 2 gallons to fill it back up..no sign of where it's going. anyone else have this problem yet??

Since this is in the 6.4 section...

Radiators on the 6.4's have been issues since day one. I'd get that checked out!

Is this for the 6.0 in your signature though?

IF it's a 6.0...Go underneath the truck and look up by the backside of the motor. Look around the back of the heads and starter, possibly on the transmission lines. If you can see coolant it could be the EGR cooler of cooler hose. I just had this problem in Dec. Warranty should cover it w/$100 deduct. The trick is getting a good tech to find the leak. Mine only leaked after warm up/cool down and left to sit in the cold. Good luck!

Check behind the driverside front bumper and look at the frame rail.....thats probably where it is leaking......thats where mine is, it a simple chrimp on the radiator that "drips" out coolant

my coolant cap was almost falling off when I picked mine up. a few California highways later, i had about a half gallon missing.

Added some Zerex G-05 and distilled water, tightened the cap. No problems since.

Any white smoke or coolant off the back of your motor?

my Radiator has been leaking for months -- I haer there may be a recall for it ,but for now I just keep a bottle of antifreeze in the tool box ,just in case.

the radiator by far has been the most common problem ive seen with the 6.4
