19101MBA010, Tank Assy., Reserve, Honda

The Tank Assy., Reserve, with the manufacturer part number 19101-MBA-010, is a crucial component of Honda vehicles. Widely known as a coolant reservoir, expansion tank, or overflow tank, this part serves a vital function in the engine's cooling system.

Its primary purpose is to provide a storage facility for antifreeze/coolant, which is not currently circulating within the engine but can be drawn upon when required. As engines heat and cool through normal operation, the coolant expands and contracts. The reserve tank provides a space for excess coolant to go when it expands, preventing it from being expelled from the system altogether, thus maintaining a consistent and appropriate coolant level.

The Tank Assy., Reserve, is typically made from high-density polyethylene (HDPE), a heat-resistant material that can withstand fluctuations in temperature and pressure within the engine bay. It is designed for a precise fit within the specific models of Honda vehicles, ensuring optimal performance and prevention of leaks.

It's important to note that while this reserve tank is durable, over time it can become susceptible to cracking or damage due to constant exposure to extreme heat, vibrations, and harsh under-the-hood conditions. The installed location of these tanks, usually in the engine compartment, makes them more prone to such wear and tear. Regular checking and maintenance, are recommended to ensure its longevity.

The manufacturer part number is specific to Honda brand vehicles, so this reserve tank will not be compatible with vehicles of other brands. Always verify the compatibility of parts with your specific vehicle model before purchase and installation.
