I just bought a 2019 honda fit sport one owner and 48k miles with manual transmission (my 1st manual car). Today is my 3rd day of ownership and when I turn on the car the coolant light stays own for almost 4 mins. Is that normal?

 

Congrats on the Fit and manual transmission! The light is operating normally. Consider the light function similar to a temperature gauge. It goes out as soon as the coolant temp comes up to normal operating temperature. It will take longer in the winter months, and will go out quicker in the hot summer months.

 

Like Alfa38 says. The blue light comes on when the engine coolant is cold and goes out when it reaches operating temperature - that's normal. If a red light comes on instead then that's a sign that the engine is overheating - that means you have a problem!

I do wish that Honda had put in a temperature gauge instead of stupid lights.

 

I use an Ultragauge in my Fit to monitor coolant temperatures and the charging system (plus other stuff for fun). Real gauges for these functions used to be present on most cars. I don't need a giant fuel gauge the same size as the speedometer and tachometer. There's plenty of room for additional gauges in the (GE8) dashboard but we can't always get what we want or need.

If all you have are the warning lights, you still have useful information. When the blue coolant light is on (up to approximately 140F), don't thrash the car. If the red coolant light comes on, pull over and stop as soon as possible. Because I can see the actual coolant temperature, I know that my car maintains a very steady temperature on the highway. In stop-and-go traffic the temperature fluctuates considerably, from around 175-177F (the highway temperature) to above 200F, when the fans kick on to pull additional air through the radiator and cool the car. I've never seen the red coolant light, which I'm not complaining about.

If the red light comes on and you can't pull over immediately, turn your HVAC temperature controller to full hot and the blower fan to high; the heat exchange box serves as an additional (small) radiator and pulls some heat from the engine into the passenger compartment. It might be enough to prevent a catastrophe if you have a serious overheating problem.
