Re: TEMP GAUGE GOES UP AND DOWN. HAS NEVER DONE THIS IN...
Try replacing thermostat, or possibly temp. sensor (should be near thermostat- threaded into block- prob 1 wire). most likely failing thermostat! make sure you get the correct replacement for it! some have different temp. ranges. 'opening' temp. should be stamped on rim of thermostat.
good luck!
