The engine coolant level can be checked at the engine coolant surge tank. The coolant level should be checked when the system is cool and not under pressure. The coolant level should be at the cold line (surge tank seam) on the coolant tank. If the coolant level is low, check for system leaks, and then slowly open the coolant surge tank cap. Add the coolant until the level reaches the Cold line (surge tank seam).

Inspect the quality of coolant. There should not be any rust deposits, scale, or oil in the surge tank or on the coolant cap. If the coolant is excessively dirty, the cooling system should be flushed and the cap replaced.

Caution: To avoid the danger of being burned, do not remove the cap while the engine, radiator, and surge tank are still hot. Scalding fluid and steam can be blown out under pressure.




1. Remove the coolant cap from the coolant surge tank.

Caution: Refer to Vehicle Lifting Caution in the Preface section.

2. Raise the vehicle.



3. Remove the lower cradle splash shield fasteners and remove.




Important: Failure to use a drain hose will result in uncontrolled coolant flow direction.

4. Slide a pliable piece of hose with an inside diameter of 3/8 in. over the radiator drain tube.

Important: A 7.6 L (8 qt) coolant container will be needed.

5. Route the hose rearward and down to an approved coolant container.

Important: Open the drain valve 1-2 turns only.

6. Use a flat blade screwdriver or a pliers to open the radiator drain valve and the drain coolant.

Approximately 3.5 L (4 qt) of coolant can be drained from the radiator. Additional coolant will remain in some cooling system components.

7. When completely drained, close the coolant drain valve and remove the drain hose.



8. Install the lower cradle splash shield and fasteners.

Tighten
Tighten the lower cradle splash shield fasteners to 5 N·m(44 lb in).
