Review MACK Reservoir

The Mack M22 QE31126M reservoir is a crucial component of Mack's heavy-duty engine cooling system. This reservoir is designed to provide an adequate volume of coolant to maintain optimal engine operating temperatures in various operating conditions.

The M22 QE31126M reservoir is engineered with a unique shape and capacity to ensure effective cooling and pressure capability. It has a total capacity of 12.6 quarts (11.8 liters) of coolant, which is sufficient to meet the cooling demands of Mack's powerful engines.

The reservoir is manufactured using high-quality materials, including a durable polymer tank and a sturdy, ribbed design. Its shape includes a wide, flat bottom that provides stability during installation and operation. Additionally, the reservoir features a large, easily accessible fill cap and a sight glass that allows for quick and accurate coolant level checks.

One of the most notable features of the Mack M22 QE31126M reservoir is its pressure capability. It is designed to operate at up to 18 psi (126 kPa) system pressure, ensuring that the engine remains adequately cooled even under heavy loads or high-temperature operating conditions.

The reservoir also includes an integrated pressure relief valve that protects against excessive pressure build-up, preventing potential damage to the engine or cooling system. The valve is designed to open at a predetermined pressure, releasing excess pressure and maintaining system safety.

The Mack M22 QE31126M reservoir is also equipped with a thermostat housing, which allows for easy installation and removal of the engine thermostat. The housing is designed to securely hold the thermostat in place while allowing for proper coolant flow around it.

In summary, the Mack M22 QE31126M reservoir is a high-performance, durable cooling system component that provides effective engine cooling and pressure capability. Its large capacity, sturdy design, and convenient features make it an essential component for Mack heavy-duty engines.

2. Weight: The cast aluminum material makes this reservoir heavier than some other options, but its durability and large capacity make it a worthwhile investment for commercial applications.

3. Limited Compatibility: While this reservoir fits most Mack trucks, it may not be compatible with all models. It's essential to verify the compatibility of this part before making a purchase.

The Mack 22QE31126M reservoir is a high-quality, durable component that offers a large cooling capacity for Mack trucks. Its price point and weight may be a drawback for some, but for those who require a robust cooling system for heavy-duty applications, this reservoir is an excellent investment.

If you operate a Mack truck and require a reliable cooling component that can handle long-haul trips or heavy-duty applications, the Mack 22QE31126M reservoir is a worthwhile investment due to its durability, large capacity, and easy installation.
