I live in Texas where it’s hot, but I started my car today after leaving it outside and the c to h gauge was at 1 block. After driving it for about 2 mins the c is slowly gettting back to the middle. Is this a issue? What’s happening?
If it started at one bar and went up quickly, quicker than normal I mean, then you may be low on coolant. If it doesn't go up and the car has been running and is up to temp, you may have too much coolant or the display is acting up, its common in our generation that the segmented displays have bad solder connections.
Yes, middle of the gauge is proper operating temperature, cold or hot outside doesn't matter. The only thing that might be different as to if it's cold or hot outside is how quickly it will head up to that point.
