Description

The Mishimoto Ford Mustang EcoBoost, V6, V8 Aluminum Coolant Expansion Tank offers enhanced reliability and engine bay aesthetics. This tank is engineered for a direct fit in 2015-2023 Ford Mustang models, accommodating EcoBoost, V6, and V8 engines. Its internal baffles are crucial for preventing coolant starvation during spirited driving, by ensuring coolant stays near the overflow port and preventing air from entering the system, especially during high-speed cornering, braking, and acceleration. Designed with functionality and durability in mind, the Mishimoto expansion tank includes a convenient sight glass for accurate monitoring of coolant levels in both hot and cold states. Unlike plastic OEM tanks which can degrade over time due to constant temperature fluctuations, this Mishimoto tank is constructed from durable, TIG-welded aluminum for maximum longevity. The design also incorporates an overflow nipple on the fill neck, allowing for the addition of an overflow reservoir to meet NHRA requirements. It is available in a polished finish or an anodized black powder coat to complement various engine bay styles. As a testament to its quality, the Mishimoto Aluminum Coolant Expansion Tank is backed by the Mishimoto Lifetime Warranty.
