Overview

The Mishimoto Racing Thermostat is designed for 5.7L/6.1L/6.4L/6.2L Hemi engines in Dodge Charger and Challenger models from 2006-2019. It activates at a lower temperature of 180 F, compared to standard 203 F thermostats. This allows coolant to flow through the system earlier, promoting cooler engine temperatures and extending engine life.
Show original supplier description
The Mishimoto Racing Thermostat is engineered to enhance the cooling efficiency of high-performance Hemi engines, specifically for the 5.7L, 6.1L, 6.4L, and 6.2L variants found in Dodge Charger and Challenger models from 2006 to 2019. This performance thermostat opens at a lower temperature of 180 F, significantly earlier than the stock 203 F thermostat. By allowing coolant to circulate through the engine sooner, it helps to reduce and maintain lower engine temperatures, which is crucial for extending engine longevity and maximizing performance, whether your vehicle is stock, cammed, or supercharged. The product includes the Mishimoto Lifetime Warranty, underscoring the brand's commitment to quality and durability. Installation is rated as easy, making it a straightforward upgrade for enthusiasts looking to improve their vehicle's cooling system. Key benefits include improved cooling efficiency, the prevention of high engine temperatures, and earlier coolant flow, all contributing to a more reliable and potentially higher-performing engine. The activation temperature of 180 F is a significant step down from the factory 203 F, offering a tangible improvement in thermal management.
