Any body know what the small cooler is for located under the drivers side of cab.I can see fuel lines going & coming from it but have no idea what purpose it serves.I have one on my 01 /DA.If your up north in the cold & snow & ice plug up what good will it be.Im in the south were it dos'nt plug except with dirt & dust,then I can carefully spray clean it with a water hose like a radiator.Never seen one on a truck except the DA's.Got me puzzled.

Sounds like it to me. I just scrub it with a wheel brush every once and awhile to keep it clean. Fill in your sig so we know what your truck has got.
