2. Open radiator drain plug at the bottom of radiator (or remove lower radiator hose) and remove radiator cap.
3. Remove reservoir tank, drain coolant, then clean reservoir tank.

- Be careful not to allow coolant to contact drive belts.
4. Cover the exhaust tube heat shield to prevent from splashing coolant.










5. Remove cylinder block drain plug and air relief plug.
6. Check drained coolant for contaminants such as rust, corrosion or discoloration. If contaminated, flush engine cooling system.
