Product Title
Proton Radiator Coolant Spare Tank / Overflow Reservoir (Genuine OEM)
OEM: PW820258
SKU: PARTS-ZZ-000045
ùð Product Description
This is the radiator coolant spare tank / coolant overflow reservoir used in many Proton passenger cars.
It is part of the engine cooling system, designed to store excess coolant when the engine heats up and allow coolant to flow back into the system as the engine cools down.
This component helps maintain proper cooling system pressure, prevents coolant loss, and reduces the risk of engine overheating.
þ This is not a radiator core — it is the coolant expansion / reserve tank mounted in the engine bay.
