if my temp warning light comes on at 210 degrees how long can I drive
I wouldn't at all. Pull off to the side of the road and get a tow to the garage of your choice.
Celcius or Fahrenheit? At 210°C the motor is toast. At 210°F the engine is not overheating. Hope that helps! Jim
If the temperature warning light is coming on at 210 then something is wrong, water boiling point is 212 but add coolant and pressure and that goes way up. Sounds like you have a bad sender. A live data scan can show what the engine is actually running at temperature wise.
