Cooling System Draining

When servicing the cooling system, it is essential that coolant does not drip onto the accessory drive belt and/or pulleys. Shield the belt with shop towels before working on the cooling system. If coolant contacts the belt or pulley, flush both with clean water.

WARNING: DO NOT REMOVE HOSE CLAMPS OR HOSES, CYLINDER BLOCK DRAIN PLUGS, COOLANT BOTTLE CAP, OR OPEN THE RADIATOR DRAINCOCK, WHEN THE SYSTEM IS HOT AND UNDER PRESSURE BECAUSE SERIOUS BURNS FROM THE COOLANT CAN OCCUR.






1. Open radiator drain located at the lower right side of radiator. Do Not Use pliers to open draincock.
2. Remove coolant pressure bottle cap and open the thermostat bleed valve.
3. Remove the cylinder block drain plug(s) located below each exhaust manifold.

CAUTION: The cooling system normally operates at °97 - 124 kPa (14 - 18 psi) pressure. Exceeding this Pressure may damage the radiator or hoses.
