Fuel efficiency, torque, and simplicity are just a few characteristics that give the Cummins its stellar reputation. We're huge fans of the Cummins engine, which is why we've developed a high-temperature thermostat for the 1989-1993 5.9L 12v Cummins. This Mishimoto thermostat activates at a higher temperature (189.5F) compared to the factory thermostat (180F). By raising the activation temperature, coolant flows through the system later, promoting quicker engine warmup. The Mishimoto high-temperature thermostat is ideal for vehicles in cold climates, where rapid warmup and quicker in-cabin heat is vital. This thermostat includes a high-quality replacement gasket and our signature Mishimoto Lifetime Warranty.","brand":"Mishimoto","offers":[{"title":"Default Title","offer_id":49876750762270,"sku":"MISMMTS-RAM-89H","price":64.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0759\/7965\/3406\/files\/02c75f9348d7ce4f21fa6a76fa0d5679.jpg?v=1750197197","url":"https:\/\/shop.signatureautohaus.com\/products\/mishimoto-89-93-dodge-5-9l-cummins-87-5c-high-temperature-thermostat","provider":"Signature Autohaus","version":"1.0","type":"link"}
