Draining and Filling Cooling System Notes Draining and Filling Cooling System Draining Procedure Important: Do NOT add any engine coolant supplement sealant pellets to the cooling system. Drain and refill the engine cooling system every 5 years or 240 000 km, (150,000 ml) , whichever occurs first. 1. Park the vehicle on a level surface. 2. Remove and clean the coolant recovery reservoir. Caution: To avoid being burned, do not remove the radiator cap or surge tank cap while the engine is hot. The cooling system will release scalding fluid and steam under pressure if radiator cap or surge tank cap its removed while the engine and radiator are still hot. 3.1. Slowly rotate the cap counterclockwise to the detention tab. Do not press down while rotating pressure cap. 3.2. Wait until any residual pressure, indicated by a hissing sound, is relieved. 3.3. After all hissing stops, press down on the radiator cap and rotate the cap counterclockwise in order to remove the cap. Important: Recover and store used coolant in a used coolant holding tank and submit the used coolant for recycling on a regular basis. Do NOT pour used coolant down the drain. Ethylene glycol antifreeze is very toxic. Disposing of ethylene glycol into the sewer system or ground water is both illegal and ecologically unsound. 4. Place a drain pan under the radiator drain cock in order to collect all of the used coolant. 5. Open the radiator drain cock. If only partial cooling system draining is required, drain enough coolant to perform the procedure 6. Open the air bleed valve on the thermostat housing 2 full turns. 7. Open the air bleed valve above coolant pump 2 full turns. 8. Place a drain pan under the engine block drains in order to collect the used coolant. Important: Allow the coolant to drain completely
