Whether you're tearing up the trails or hauling hay in the fields, you need your Arctic Cat 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 Arctic Cat's cooling system isn't maintained with quality parts. Luckily, Mishimoto has you covered with this low temp thermostat for your 1998-2013 Arctic Cat 500. Our thermostat fits just like stock and features a lower opening temperature to help your Arctic Cat stay cool in hot climates or under high loads. 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 low temp thermostat for your 1998-2013 Arctic Cat 500 is backed by our Mishimoto Lifetime Warranty.
