92 with 2.3 motot, non turbo, takes 30-40 minutes to even get the needle off of cold. Changed out stat and cooling temp sender. The compressor cycles every few minutes and the gas mileage sucks!
There is no other reason the water temp wont come up other than the thermistat.
Whether the gauge moves or not, start the car run it for 10 min, then feel the upper hose and see how warm it feels. If that is warm your gauge may not be working properly.
had the same problem with mine and it was the thermostat. I changed it and the stupid thing failed almost immediately. finally bought the cheapest oem style one and it works great. change it out again until you get one that works...
