the 3.1 in my 95 beretta never seems to exceed 1/4 way on the temp gauge (much of the time it is less than that). also, the heater never seems to get too hot, nothing like the heater on my buddy's corsica of the same year with the 2.2l. im guessing my thermostat is stuck open or someone along the line removed the thermostat. can anyone speak from experience in having this happen, or any suggestions?
