what is the normal operating temp for a lbz. my truck runs between 160f to ABOUT 190F. I have a piece of cardboard covering about one third of the drivers side of the radiator. the outside temp is only about 45f in the morning and 60f in the afternoon. it just seems like the truck wont really warm up.
