Truck (Dakota) started to run warmer than normal last spring. Gage has no temp numbers, but with the snow gone, I parked it and used the 2wd.
Finally opened it up (winter's coming!) and found a waxy substance plugging up the passages in several different places. Wasn't sure what to expect, but wax wasn't on my short list. I flush things regular, and I've had the radiator to the shop for cleaning, but I don't know what to call this. Got any ideas what could have caused it? And should I be concerned about the block itself?
