How to service and repair the coolant reservoir on 2.3L, 3.0L, and 3.5L engines on Ford Fusion?

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.

The Coolant Reservoir in Ford Fusion automobiles is used in the cooling system and helps avoid coolant leaks additionally eliminating air in the system. There are two main types of Coolant Reservoirs used in Fusion vehicles: It mainly include two categories of tanks, and they are the overflow tank systems and expansion tank systems. In the overflow system, the coolant moves through the system from the radiator to the recovery tank whenever the pressure rises beyond the recommended level indicated on the cap while in the expansion system, the tank is under pressure as a part of the cooling system and has receiving tanks to allow expansion and contraction of the coolant. The authors suggest to conduct monitoring minimum with a goal of observing that there are no cracks, some amount of leakage, and signs of degradation resulting from aging and expansion/contraction influenced by heat. Coolant Reservoirs are important to regulate the coolant level and to avoid environmental pollution by leakage of antifreeze liquid.
