Whether you're tearing up the trails or hauling hay in the fields, you need your Polaris Ranger 400 or 500 to stay at the optimal temperature. Long periods of idling and low-speed high-load driving can cause engine temps to creep up if your Ranger's cooling system isn't maintained with quality parts. Luckily, Mishimoto has you covered with this stock temp thermostat for your 2007-2015 Polaris Ranger 400/500. Our thermostat fits and functions just like stock to restore your Ranger's cooling system to the way it rolled off the factory floor. The included O-ring makes installation easy so you can get back to work or play in no time. Like all our powersports products, this stock temp thermostat for your 2007-2015 Polaris Ranger is backed by our Mishimoto Lifetime Warranty.
