Changing coolant

Every two years or 30,000 miles (48,000 km) the cooling system should be drained, flushed and refilled.

Remove the expansion tank cap. Open the drain cock on right side of the engine block and disconnect

the lower radiator hose.

Fill coolant through the expansion tank.

The heater controls should be fully open when draining and filling.

Add coolant until the level is up to the MAX mark or slightly above.

Start engine and run until hot. Check the cooling system connections for tightness. Also re-check the

coolant level. Capacity: 9.9 US qts. = 9.4 liters (manual transmission models); 9.7 US qts = 9.2 liters

(automatic transmission models)
