pg. 61 Cooling system

Changing coolant
Every two years or 30,000 miles (50,000 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)

Cooling system, hoses and connections
Check all cooling system hoses and connections for defects or deterioration of hoses and loose clamps or fittings.

Drive belts
The belt tension can be checked by depressing the fan belt at a point midway between the alternator and fan pulleys as illustrated. It should be
possible to press down the belt about 1/4" - 3/8" (5-10 mm). This also applies to other drive belts on the engine.
If drive belts are replaced, recheck belt tension after driving 600-1,200 miles (1,000-2,000 km).
