Hi, i have a 1994 Ford Ranger XLT 2.3 5 sp. and i've had it about a year now. Runs and drives perfectly but one thing i always wondered was the temperature gauge never goes much higher then above the C. i know my gauge isn't broken because on cold start the needle is as far cold as it goes then when it's "warm" it moves up to the C on the gauge. I know a warm engine will get better fuel economy as well. I am predicting that the previous owner put a different thermostat in it or do the 2.3 4 cylinder motors just run cold?
