Replaced the thermostat approximately 2 years ago. Approximately 30,000 miles on it.

Ever since relacing it the temperature gauge remained in the normal operating range position when vehicle was turned off (after vehicle was driven and had reached normal operating temps).

Upon cooling and when turned back on the needle dropped to the cold (recently started) position and as the vehicle warmed the indication raised to a normal location. Never over-heated or had any problems.

Just recently however the needle indicator has remained in the hot or near over-heated position when starting and as vehicle warms the needle recedes a bit but still remains in a realtive hot position.

Shortly after starting the "Check Gauge" light comes on and after a couple of minutes the needle backs off a bit and the light subsequently goes off and remains off. However the indicator needle remains near the top of the reading.
