Description
Enhances Cooling System Efficiency and Engine Reliability. The PPE Coolant Overflow Tank is engineered to provide expanded coolant capacity and improved thermal regulation for demanding diesel applications. By efficiently managing coolant levels, it helps reduce the risk of overheating and pressure imbalances, supporting consistent engine performance under load or in extreme temperatures.
Long-Term Durability. Made from TIG-welded aluminum, the PPE Coolant Overflow Tank resists corrosion, cracking, and deformation far better than plastic factory tanks. Its durable construction ensures a longer lifespan, even in high-vibration and high-temperature environments commonly experienced in heavy-duty driving and towing conditions.
Functional Design with Sight Glass for Monitoring. The PPE Coolant Overflow Tank not only adds rugged functionality to your engine bay but also includes a convenient sight glass to easily monitor coolant levels. This allows for quick inspections without needing to open the system, saving time and enhancing safety during maintenance checks.
Increases Capacity and Improves Cooling System Stability. With greater volume than standard reservoirs, the PPE Coolant Overflow Tank helps accommodate thermal expansion and contraction during temperature swings. This added capacity helps stabilize coolant pressure, reducing the chances of air pockets forming in the system and ensuring optimal coolant flow to critical engine components.
Installation. Putting this PPE Coolant Overflow Tank on your 6.6L Duramax Silverado 2500 HD takes 1 hour to install.
Warranty. There is a 1-year limited warranty on this product.
Application. The PPE Coolant Overflow Tank fits late 2007.5-2010 6.6L Duramax Silverado 2500 HD models.
