WARNING: This page is about a different car, the 2003 GMC Sonoma, 2003 GMC Jimmy, 2003 Chevrolet S10 Pickup, and 2003 Chevrolet Blazer. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
Do not add cold water to the cooling system with the engine at or above operating temperature. Adding cold water causes rapid cooling, resulting in possible engine damage.
NOTE:
Do not use a solution stronger than 70 percent antifreeze. Pure antifreeze can freeze at -22°C (-8°F).
- Install the radiator inlet hose to the radiator.
- Using J 38185 reposition the radiator inlet hose clamp to the radiator.
- Place a large mouth funnel in the radiator fill opening.
Important: Under some conditions, Dex-Cool® is combustible.
Do not spill the coolant onto the exhaust system or other hot engine parts.
- Slowly add a 50/50 mixture of Dex-Cool and clean drinkable water.
- Fill to 1/2 inch below the radiator fill opening.
- Start the engine.
- As the cooling system warms up and the thermostat opens, the coolant level will drop.
- Add coolant until the level is up to the radiator fill opening.
- Replace the radiator filler cap.
- Inspect the level in the coolant recovery reservoir, add coolant if needed.
