DEF Spraying undercarrage

Recommended Posts

So Today I noticed rust stains running under my truck on the driveway! Looked under the truck and found undercoating falling off the frame and surface rust on the frame. Looks like its coming from the injection point at the particulate filter. Its a high pressure DEF (EPA piss water) spray because it's also on the underside of the bed dripping down onto the filter. Guess its going into the dealer tomorrow. Damn this stuff is corrosive as hell!! Just under 2000 miles on the truck!!
