The thermostat is a temperature-sensitive valve in the cooling system that stays closed while the engine warms up and opens to let coolant flow to the radiator once it reaches operating temperature. Related parts such as the thermostat housing, cover, gasket, O-ring, and bleed fittings keep that valve sealed and positioned correctly. A healthy thermostat helps the engine warm up quickly, hold a steady temperature, and avoid both overheating and running too cold. Riders most often replace thermostats and thermostat parts after an engine that overheats or boils over, an engine that takes forever to warm up or never reaches normal temperature, a temperature gauge that swings or reads erratically, weak cab heater output, coolant leaks at the housing or gasket, a cracked or corroded housing, a stuck-open or stuck-closed valve, or any time the cooling system is opened for service.\u003c\/p\u003e\n\u003ch3\u003eWhy Choose Genuine OEM Yamaha Parts?\u003c\/h3\u003e\n\u003cp\u003eChoosing original equipment manufacturer (OEM) parts ensures your vehicle maintains its factory-standard performance, reliability, and fuel efficiency.

This specialized engineering withstands harsh off-road vibrations, extreme temperatures, and modern fuel additives, preventing premature wear and leaks. Genuine thermostats use a precisely calibrated wax or thermal element, a corrosion-resistant valve and spring, and coolant-resistant seals matched to your engine's operating temperature, so they open and close at the right point, seal tightly, and keep coolant temperature steady through repeated heat cycles.\u003c\/p\u003e\n\u003ch3\u003eComprehensive Model Fitment (2015-Current)\u003c\/h3\u003e\n\u003cp\u003eThis genuine OEM part is engineered for a wide range of Yamaha side-by-side (SxS) and all-terrain vehicles (ATV) built from 2015 to the current model year.

Before replacing parts, check the coolant level, radiator cap, cooling fan, hoses, and water pump, since these can cause similar symptoms. Because thermostats and parts vary by model, model year, and engine, confirm the correct parts, opening temperature, and installation and bleeding procedure using your Yamaha service manual or factory schematic, or contact us with your model and VIN and we will help you match them.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: How do mud, water, sand, and heat affect thermostats and thermostat parts on the trail?\u003c\/strong\u003e\u003cbr\u003eA: Heat and repeated pressure cycles can age gaskets and seals and cause slow coolant seepage, while old or contaminated coolant can corrode the valve and make it stick. Packed mud on the radiator and engine can trap heat and make a marginal thermostat show up as overheating. After a hot, muddy, or dusty ride, rinse caked mud from the radiator and engine, check the coolant level with the engine cool, and look for seepage around the housing. Follow your Yamaha service manual for correct installation, filling, bleeding, and safe service guidance.\u003c\/p\u003e\n\u003cp class=\"MsoNormal\" style=\"margin-top: auto; margin-bottom: auto; line-height: normal;\"\u003e\u003cb\u003e\u003cspan style=\"color: #ff2a00;\"\u003ePRO TIP: \u003c\/span\u003e\u003c\/b\u003e\u003ca href=\"https:\/\/buywitchdoctors.com\/blogs\/news\/yamaha-oem-vs-aftermarket-parts-comparison\" title=\"Direct link to Buywitchdoctors.com blog about Yamaha OEM vs. Aftermarket Parts: Are Factory Components Best for Your Trail Riding?\" rel=\"noopener\" target=\"_blank\"\u003e\u003cb\u003e\u003cspan\u003e\u003cspan style=\"color: blue;\"\u003eLearn More about Yamaha OEM vs. Aftermarket Parts\u003c\/span\u003e\u003c\/span\u003e\u003c\/b\u003e\u003c\/a\u003e\u003c\/p\u003e\n\u003cp class=\"MsoNormal\" style=\"margin-top: auto; margin-bottom: auto; line-height: normal;\"\u003e \u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003e\u003cb\u003e\u003cspan style=\"color: #ff2a00;\"\u003ePRO TIP:\u003c\/span\u003e \u003c\/b\u003e\u003ca href=\"https:\/\/buywitchdoctors.com\/blogs\/news\/upper-radiator-hose-hot-lower-hose-cold-utv-atv\" rel=\"noopener\" title=\"Direct link to Buywitchdoctors.com blog about UTV\/ATV Cooling Issues Explained\" target=\"_blank\"\u003e\u003cb\u003e\u003cspan style=\"color: blue;\"\u003eUTV\/ATV Cooling Issues Explained.\u003c\/span\u003e\u003c\/b\u003e\u003c\/a\u003e\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003e\u003cb\u003e\u003cspan style=\"color: #ff2a00;\"\u003ePRO TIP:\u003c\/span\u003e\u003c\/b\u003e \u003cb style=\"mso-bidi-font-weight: normal;\"\u003e\u003ca href=\"https:\/\/buywitchdoctors.com\/blogs\/news\/the-complete-guide-to-utv-amp-atv-lubricants-coolants-and-fuel-treatments\" rel=\"noopener\" title=\"Direct link to buywitchdoctors.com blog about The Complete Guide to UTV \u0026amp; ATV Lubricants, Coolants and Fuel Treatments\" target=\"_blank\"\u003e\u003cspan style=\"color: blue;\"\u003eThe Complete Guide to UTV \u0026amp; ATV Lubricants, Coolants and Fuel Treatments.\u003c\/span\u003e\u003c\/a\u003e\u003c\/b\u003e\u003c\/p\u003e\n\u003cp class=\"MsoNormal\" style=\"mso-margin-top-alt: auto; mso-margin-bottom-alt: auto; line-height: normal;\"\u003e\u003cb\u003e\u003cspan style=\"mso-fareast-font-family: 'Times New Roman'; mso-bidi-font-family: Calibri; mso-bidi-theme-font: minor-latin; color: #ff2a00;\"\u003ePRO TIP:\u003c\/span\u003e\u003c\/b\u003e\u003cb\u003e\u003cspan style=\"mso-fareast-font-family: 'Times New Roman'; mso-bidi-font-family: Calibri; mso-bidi-theme-font: minor-latin;\"\u003e \u003ca href=\"https:\/\/buywitchdoctors.com\/blogs\/news\/signs-of-bad-utv-water-pump-replacement-guide\" rel=\"noopener\" title=\"Direct link to Buywitchdoctors.com blog about Signs of a Bad UTV Water Pump: How to Diagnose, Test, and Replace Your Cooling System\" target=\"_blank\"\u003e\u003cspan style=\"color: blue;\"\u003eSigns of a Bad UTV Water Pump: How to Diagnose, Test, and Replace\u003c\/span\u003e\u003c\/a\u003e\u003c\/span\u003e\u003c\/b\u003e\u003cspan style=\"mso-fareast-font-family: 'Times New Roman'; mso-bidi-font-family: Calibri; mso-bidi-theme-font: minor-latin;\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"MsoNormal\" style=\"mso-margin-top-alt: auto; mso-margin-bottom-alt: auto; line-height: normal;\"\u003e\u003cb\u003e\u003cspan style=\"mso-fareast-font-family: 'Times New Roman'; mso-bidi-font-family: Calibri; mso-bidi-theme-font: minor-latin; color: #ff2a00;\"\u003ePRO TIP:\u003c\/span\u003e\u003c\/b\u003e\u003cb\u003e\u003cspan style=\"mso-fareast-font-family: 'Times New Roman'; mso-bidi-font-family: Calibri; mso-bidi-theme-font: minor-latin;\"\u003e \u003c\/span\u003e\u003c\/b\u003e\u003cspan style=\"mso-fareast-font-family: 'Times New Roman'; mso-bidi-font-family: Calibri; mso-bidi-theme-font: minor-latin;\"\u003e\u003ca href=\"https:\/\/buywitchdoctors.com\/blogs\/news\/signs-bad-utv-atv-thermostat-how-to-test\" rel=\"noopener\" title=\"Direct link to Buywitchdoctors.com blog about Signs Your UTV or ATV Thermostat is Bad (And How to Test It)\" target=\"_blank\"\u003e\u003cb\u003e\u003cspan style=\"color: blue;\"\u003eSigns Your UTV or ATV Thermostat is Bad (And How to Test It\u003c\/span\u003e\u003c\/b\u003e\u003c\/a\u003e)\u003c\/span\u003e\u003c\/p\u003e\n\u003cbr\u003e\u003cstrong\u003eUpgrade Your Ride's Cooling System Performance Today\u003c\/strong\u003e\u003cbr\u003eA factory-fit thermostat keeps your engine at the right temperature for easier starts, steadier power, and longer engine life on every ride.
