What Causes the Cruze to Overheat?
1 Answers
The water pump is malfunctioning; there is no water in the engine oil, but the possibility of water leaking into the combustion chamber cannot be ruled out; the water temperature sensor is faulty; the exhaust advance angle is delayed; driving at low gear with high speed or high gear with low speed can also easily cause the water temperature to rise. When the water pump is working normally, it vibrates at its inherent frequency, and a large amount of water overflows from the outlet. Here are some solutions for the Cruze's high water temperature: 1. Method One: When the engine temperature is too high, you can touch the upper and lower water pipes to check their temperatures. If there is a significant temperature difference between the two pipes, it can be determined that the thermostat is not working. If you cannot purchase a replacement part immediately, you can remove the thermostat as an emergency measure and replace it as soon as you get home. 2. Method Two: If there is air in the cooling system, it can create an airlock, disrupting the circulation of the coolant and causing the engine temperature to rise. To release the air, follow these steps: run the engine at high speed, gently unscrew the radiator cap until gas starts to escape. Some coolant will flow out with the gas. Repeat this process several times until you feel all the gas has been released. After troubleshooting, replenish the coolant promptly. 3. Method Three: If the vehicle has been driven on dirt roads or muddy sections for a long time, debris may accumulate on the radiator, affecting its cooling efficiency and leading to high water temperature. In this case, you can first use compressed air to blow through the radiator fins.
