Coolant: Service and Repair
Draining and Filling the Cooling System
DRAINING AND FILLING THE COOLING SYSTEM
Use the following procedures if a non-aqueous coolant exchanger such as (Pro Fill) J 75010-KM (or equivalent) is not available.
Draining
Important
^
This procedure significantly increases the amount of used coolant and diluted hazardous waste.
1. Park vehicle on a level surface.
2. Remove and clean coolant recovery reservoir.
CAUTION: To avoid being burned, DO NOT remove the radiator cap while the engine is at normal operating temperature. The cooling system
will release scalding fluid and steam under pressure if the cap is removed while the engine and radiator are still hot. This could result in a large
coolant loss and possibly personal injury.
3. Remove tile radiator cap when the engine is cool by:
A. Slowly rotating pressure cap counterclockwise to detent. Do not press down while rotating pressure cap assembly.
B. Wait until any remaining pressure (indicated by a hissing sound) is relieved.
C. Afier all hissing stops, press down on pressure cap and continue to rotate counterclockwise.
Important
Recover coolant and store in a used coolant holding tank and submit the used coolant for recycling on a regular basis. This procedure significantly
increases the amount of used coolant and diluted hazardous waste.
4. Place drain pan under vehicle to collect all drained coolant.
5. Open the radiator drain valve located at the bottom of the left-hand radiator end tank.
6. On 3.1L Engines open the air bleed vent on the throttle body return pipe (above the coolant pump). The air bleed vent should be opened two to
three turns.
