Heater and radiator hoses, and
other engine parts, can be
very hot. Don't touch them. If you
do, you can be burned.
Don't run the engine if there is a
leak. If you run the engine, it
could lose all coolant. That could
cause an engine fire, and you could
be burned. Get any leak fixed
before you drive the vehicle.
