Opening at 45°C, this thermostat regulates coolant flow to the radiator — it remains closed when the engine is cold to accelerate warm-up, then opens progressively to allow coolant to circulate through the radiator as operating temperature is reached. A stuck-closed thermostat causes overheating; a stuck-open thermostat causes the engine to run too cold and struggle to reach optimal operating temperature, both of which degrade performance and engine longevity.\u003c\/p\u003e\n\u003cp\u003eCompatible with the 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.
