Why Upgrade the Factory Coolant Tank?

The OEM coolant reservoir on the 2013-2018 Ram 6.7L Cummins is made of plastic, which can become brittle and cloudy over time, making it difficult to monitor coolant levels and increasing the risk of cracking or leaks.

Upgrading to an aluminum coolant tank provides:

• Longer service life
• Increased resistance to heat cycles
• Reduced risk of coolant leaks
• Improved engine bay aesthetics
