I have a 99 SL2 with 60k miles. There is a single light for both temperature and coolant level. A few months ago the light came on shortly after starting the car. It went away after a few minutes. It happened again and now happens whenever I drive the car, with the light coming on randomly while driving.
The light is coming right after a cold start, and during driving, even though the needle isn't even 1/4 way up. The temperature never gets up to the halfway mark, even sitting in traffic. I notice that the light sometimes stops blinking after a turn or after going up or down a hill.
The car has been running without a problem hasn't been overheating, and the coolant level is fine. Any idea what might be the cause and if so how would I fix it????
The coolant appears to be the appropriate color as well.
