I've got a '93 350 Trail Boss with 1500 miles on it that I am suspecting may have an engine, or perhaps, an exhaust pipe overheating problem. My temp warning light doesn't come on but it seems that lately my right leg is being exposed to more heat than normal and the fan kicks in more often than it used to. Is this normal? Anyone have any suggestions as to what the engine temperature should be at, how to check if the water pump is functioning, etc., etc.? I'd like to make sure there isn't anything wrong that will eventually result in a melt-down.
