Nissan Cube overheating issue with frequent overflow filling, cools down when overdrive is off on Nissan Cube

Some Nissan Cube owners report experiencing overheating issues, particularly frequent overflow filling, which may be linked to several factors. These owners often find that their engine cools down when overdrive is turned off, suggesting a potential problem with the vehicle's cooling system. Common issues include insufficient coolant levels, which can lead to overheating if not addressed, and coolant leaks from hoses or the radiator that reduce coolant availability. Additionally, some owners encounter a malfunctioning thermostat that fails to regulate coolant flow, resulting in engine overheating. Clogged radiators are also reported, as they can obstruct heat dissipation, while air pockets in the cooling system may contribute to overheating if not properly bled. Lastly, faulty radiator caps can lead to coolant leaks and exacerbate overheating problems. Addressing these concerns is crucial for resolving the overheating issues in the Nissan Cube.
