Flushing Cooling System

CAUTION:

NEVER remove radiator filler cap while coolant or engine is hot. Explosive release of fluids from pressurized cooling system can cause serious burns to you or others. ALWAYS loosen water pump drain valve and engine block drain plug slowly to relieve any excess pressure. Add coolant directly into radiator when cooled.

1. Shut off engine and allow to cool for 15-20 minutes.
