This spring loads the thermostat retaining bracket (R.222202) to hold the thermostat (R.222125) firmly in its seated position within the thermostat holder. A fatigued or missing spring allows the thermostat to unseat under coolant pressure, causing unmetered coolant bypass, erratic temperature control, and ultimately the thermostat to be ejected from its housing under race conditions.\u003c\/p\u003e\n\u003cp\u003eCompatible with thermostat-equipped head covers (R.613103 Black, R.613104 Red) on all Rotax 125 MAX EVO variants: \u003cstrong\u003eRotax 125 Senior MAX EVO, Junior MAX EVO, Mini MAX EVO, Micro MAX EVO\u003c\/strong\u003e.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Part Number:\u003c\/strong\u003e R.239950\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e Rotax 125 Senior MAX EVO, Junior MAX EVO, Mini MAX EVO, Micro MAX EVO (with thermostat head covers R.613103 or R.613104)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eCMC Karting stocks the thermostat spring alongside the complete thermostat assembly parts.\u003c\/p\u003e","brand":"KSG\/Karting Solutions Group","offers":[{"title":"Default Title","offer_id":48168038891741,"sku":"R.239950","price":7.84,"currency_code":"USD","in_stock":true}],"url":"https:\/\/cmckarting.com\/products\/rotax-max-thermostat-compression-spring","provider":"CMC Karting","version":"1.0","type":"link"}
