What to Do When the Coolant Light Comes On in a Volkswagen?
1 Answers
Turn off the air conditioning and turn on the heater to allow the engine's heat to dissipate through the heater ducts, thereby reducing the temperature of the engine's coolant. Inspect the surface of the radiator to see if the fins are excessively bent, dirty, or blocked by leaves, insects, or other debris. First, check the reservoir to see if the coolant level is insufficient; then open the radiator cap to check if there is enough coolant in the radiator.
