Freightliner Cascadia Coolant Reservoir Tanks

This ensures a direct-fit replacement without modifying hoses, brackets, or sensors, so the tank integrates seamlessly with the existing cooling system and factory coolant level sensors.

Common signs include visible cracks, coolant leaks near the tank, discolored or milky coolant, frequent low-coolant warnings, or a tank that no longer holds pressure properly. Sun exposure and heat cycling can also cause plastic tanks to become brittle over time, leading to stress fractures.

Most Cascadia coolant reservoir tanks are molded from high-density, UV-stabilized polypropylene or similar heat-resistant plastic designed to withstand engine bay temperatures, pressure cycling, and long-term exposure to glycol-based coolant without warping or cracking.

Pricing for heavy-duty truck reservoir tanks generally falls within a few hundred dollars depending on the specific model year and fitment. Exact pricing varies by tank design and included components such as caps and level sensors, so check current listings for accurate figures.

Yes, most Cascadia reservoir tanks are designed as bolt-on, direct-fit replacements that mount using existing brackets and connect to factory hoses.
