With a SEARCH, you will find:asdasc said:How about on the temp gage? Any idea what the marks represent? Where does an average engine run? My temp gage needle stays just past the very left hand mark when fully warmed up. If I pull the wire, it drops way to the left, so I know something is working. Even when the engine is cold, it is a hair lower and it moves to the right as the engine warms up, but only a 1/16" or so.
