Reservoir

Before conducting maintenance on the coolant reservoir of 2.3L, 3.0L and 3.5L engines ensure the engine temperature is low because opening the cooling system presents risks of serious injuries from steam pressure and hot liquid. The release of cooling system pressure starts when users twist the pressure relief cap counter-clockwise by one half turn before removing the cap. Hose clamp pliers should secure the lower degas bottle hose while a suitable suction device draws coolant from the bottle. Remove any wiring retainer surrounding the degas bottle before disconnecting both hoses which connect the radiator and degas bottle. Place all components aside. The degas bottle-to-thermostat housing hose requires disconnecting for 3.5L engines followed by its placement aside. The next step requires users to remove the nut from the lower degas bottle together with its bolt then detach the bottle from its installation. The fasteners must be tightened to 9 Nm (80 lb-inch) while following the opposite installation process for the degas bottle. Follow the procedure by adding the specified coolant mixture to reach the proper fill level inside of the degas bottle.

Service and repair of the coolant reservoir degas bottle for 2.3L, 3.0L and 3.5L engines requires an engine cooldown before opening the cooling system due to avoided risks of severe personal injury from pressurized steam and hot liquid. The cooling system pressure will dissipate by turning the pressure relief cap counterclockwise one half rotation before you remove it. You should use hose clamp pliers to secure the lower degas bottle hose before using a suitable suction device to siphon coolant from the degas bottle. Disconnect the wiring retainer from the degas bottle before disconnecting the degas bottle-to-radiator hose which should be placed aside. The degas bottle-to-thermostat housing hose can be removed from 3.5L engines before placing it to the side. Disconnect the lower degas bottle hose and remove its nut, bolt and degas bottle sequence. The fasteners for installing the degas bottle should be tightened up to 9 Nm (80 lb-in) before carrying out the removal steps in reverse order. Complete the degas bottle filling process by adding the essential coolant mixture according to the specified level.

Service of the coolant reservoir begins with draining the cooling system. The procedure requires users to disconnect the upper degas bottle hose before placing it to the side. Then they should disconnect the lower degas bottle hose which they also should set aside. Proceed by tightening the new installation screws from the degas bottle with 9 Nm (80 inch lbs.) torque. The service procedure ends with filling and bleeding operations for the cooling system following the removal steps in reverse order.
