What Causes the Nissan Bluebird's Water Temperature to Sometimes Be High and Sometimes Normal?

[StJayce]

Nissan Bluebird's water temperature sometimes high and sometimes normalThe reasons for the Nissan Bluebird's water temperature sometimes being high and sometimes normal are as follows: Low coolant level: This needs to be checked and is basically the only thing you can check yourself. If you're on the highway or in a remote area and don't have coolant in the car, you can temporarily use water as a substitute. Be careful not to open the radiator cap or reservoir cap immediately after stopping the car, as the internal pressure is too high and it will spray out instantly. Wait for the temperature to cool down a bit before slowly opening the reservoir cap. Dirty radiator: The radiator has many pores formed by cooling fins, which can easily get clogged with lint, sludge, etc., reducing ventilation and cooling efficiency. In winter, poor cooling may not be a big issue because the ambient temperature is low. However, in summer when the ambient temperature is already high, a clogged radiator with poor cooling can easily cause the water temperature to rise. This situation can be resolved simply by cleaning the radiator.
