INFINITI M35 overheating issue after thermostat replacement with no heat while stationary on INFINITI M35

Some Infiniti M35 owners report experiencing overheating issues after replacing the thermostat, particularly when no heat is felt while stationary. These problems may stem from incorrect thermostat installation, emphasizing the need for an OEM part and adherence to manufacturer specifications. Additionally, using the correct coolant and ensuring the radiator cap is appropriate for the vehicle are critical factors. Some owners may also discover unnoticed radiator leaks that persist despite the thermostat replacement, necessitating a thorough inspection and potential replacement of the radiator. Furthermore, neglecting to perform a cooling system flush during the thermostat replacement can lead to complications, as can failing to properly bleed the cooling system, which is essential for removing air pockets that could cause overheating. Lastly, if the vehicle overheats shortly after driving, it is crucial to allow the engine to cool down and seek professional assistance if temperatures do not stabilize. Addressing these issues can help resolve overheating concerns and restore proper heating functionality in the Infiniti M35.
