Coolant Reservoirs

Coolant reservoirs are vital components within a vehicle's cooling system, designed to manage the expansion and contraction of engine coolant. As an engine coolant reservoir stores excess coolant, it plays a crucial role in maintaining optimal engine temperature and regulating pressure within the system.

These essential parts, often referred to as a radiator overflow tank or coolant overflow tank, are typically constructed from translucent plastic. This design choice allows for easy visual inspection of the coolant level, ensuring proper maintenance. Beyond their primary function, some aftermarket options for a coolant expansion tank or coolant tank are available in various colors, offering a degree of customization. When selecting a coolant reservoir tank, it's important to consider factors such as its overall durability, the appropriate capacity for your vehicle, and its compatibility with your specific coolant type. While not directly related to engine cooling, some vehicles may also have a power steering reservoir for their power steering fluid.
