Heavy-Duty Molded Construction: The Freightliner Cascadia Coolant Reservoir Advantage

The Freightliner Cascadia Coolant Reservoir (Automann Part # 575.10115) is manufactured from high-grade heat-stabilized plastic to resist the extreme temperature fluctuations of modern heavy-duty engines. This 2-cap system is engineered for precise pressure management, utilizing a 21 PSI pressure cap and a dedicated filler cap to ensure the system remains sealed under high-stress hauling. Note: This reservoir also features a dedicated port for the coolant level sensor (577.46316), ensuring your dashboard alerts remain accurate.

As we continue to build the largest inventory of commercial truck parts in Illinois, we prioritize cooling components that prevent overheating. This reservoir is a direct professional-grade replacement for Freightliner A0532836000 and A05-32836-000 found on 2018-2026 models. Over time, plastic tanks can become brittle and develop hairline cracks; upgrading to this Fleet Standard assembly restores the reliability of your cooling system and helps avoid costly emergency repairs.
