Genuine Part
Genuine: Original manufacturer part. This product is the original part designed and produced by the vehicle manufacturer.
Coolant Expansion Tank for the engine cooling system on the 5.0L V8 naturally aspirated petrol engine.

The tank holds the coolant reserve and absorbs the change in coolant volume as the engine heats and cools, keeping the radiator and heater circuit full and allowing entrained air to separate out of the coolant. It carries the pressure cap that sets the operating pressure of the cooling system.

Moulded coolant tanks are a service item: age and repeated heat cycling embrittle the plastic, and hairline cracking at the seams or hose spigots is a common source of gradual coolant loss.
