A - Surge Tank Cap

B - Max Cold Line

Shut OFF engine, set park brake and remove key. Avoid being scalded when opening surge tank cap. Never open cap when engine is hot and never fill cooling system when engine is overheated. Open cap slowly to relieve pressure. Pour coolant in slowly. Check coolant level when engine is cold.

A special cap is used on the surge tank and radiator. If cap is damaged or missing, it must be replaced by an equivalent cap.

Never pour cold water into a hot engine as it might crack cylinder block or head. Do not operate engine without coolant.

Remove surge tank cap (A) and fill until fluid is at "Max Cold" line (B).

Install cap on surge tank, turn ON heater, and run engine until it reaches operating temperature.

Carefully remove cap from surge tank and refill as necessary. Install cap on surge tank.

When engine is cool, coolant level should be at "Max Cold" line.

Coolant level must be between "Max Cold" and "Min Cold" lines. Add coolant as needed if coolant is below "Min Cold" line.
