You can be bu 3d if you spill coolant on hot
engine parts. Coolant contains ethylene
glycc
and it will burn if the engine parts are hot
enough. Don’t
spill coolant on a hot engine.
When the Luolant in the coolant recovery ~~IMC is “1 or
above
“FULL COLD,” start your vehicle.
If the overheat warning continues, there’s one more
thing
you can try. You can add the proper coolantmix
directly to the radiator, but be sure the cooling system is
cool before
you do it.
