NOTE:
When adding coolant, use DEX-COOL® coolant. If silicated coolant is added to the system, premature engine, heater core or radiator corrosion may result. In addition, the engine coolant will require change sooner - at 50,000 km (30,000 mi) or 24 months.
- Ensure that the radiator drain cock is closed.
- Ensure that the heater hoses are secure to the fittings.
- Add the DEX-COOL® to the radiator, then add clean drinkable water to the cooling system. If you use the old coolant, ensure that the solution is clean and clear, and that the solution is a 50/50 mixture of DEX-COOL® and water.
- Place a large top funnel in the radiator filler neck or surge tank.
- Slowly pour in the coolant. Because the thermostat is closed, filling the cooling system may be slow.
- After you fill the cooling system, start the engine and let the cooling system warm up. When the thermostat opens, the coolant level may drop. If the level drops, add coolant as needed.
- Install the radiator cap.
- Inspect the coolant level in the recovery reservoir tank. Add coolant as needed.
