Mishimoto Engine Coolant Reservoir

The Mishimoto Engine Coolant Reservoir line offers aluminum replacement coolant reservoirs, also called degas bottles, expansion tanks or coolant overflow tanks. They are designed for diesel truck cooling systems. Each one replaces a factory plastic tank that can crack, warp or leak as it ages under heat and pressure.

Key Features:

• Aluminum construction for better durability and heat resistance than stock plastic tanks
• Built to hold up to the pressure and temperature cycling of a diesel cooling system
• Works as the system's expansion and degassing point, which helps manage coolant volume and trapped air
• Designed as a direct replacement for the factory reservoir, with no modifications needed in most cases
• Finish options vary by part number

Mishimoto is known for performance cooling components. This line gives owners a stronger, longer-lasting alternative to the original tank. It suits trucks that are towed with, hauled with or modified for more power, and it also works for routine replacement of an aging reservoir.
