If the water temperature is not high but the radiator keeps losing water, possible causes include rising water temperature, malfunctioning water pump or thermostat, or poor sealing of the cylinder gasket. Here are some explanations regarding why the radiator keeps losing water even when the water temperature is not high: 1. Function of the Radiator: When the engine's water temperature is high, the water pump circulates water repeatedly to lower the engine's temperature and protect it. In winter, if the water temperature is too low, the water circulation stops to prevent the engine from becoming too cold. 2. Solutions: (1) Regularly check the radiator and replenish water in time. (2) Repair or replace the water pump or thermostat to restore normal function. (3) Ensure proper sealing of the cylinder gasket.

What are the reasons for the Dongfeng Tianjin automatic stalling?

Dongfeng Tianjin automatic stalling can be caused by issues with fuel quality, carbon buildup in the engine or spark plugs, and damage to the water temperature sensor. Below are the relevant explanations: 1. Fuel quality issues: The fuel quality barely meets the standard. While this may not affect the vehicle's driving performance, it can cause damage to the engine. 2. Carbon buildup in the engine or spark plugs: After some use, the engine may accumulate carbon deposits, which can lead to engine damage. The accumulated heat can cause disorderly ignition, resulting in engine knocking. In such cases, the engine malfunction indicator light will illuminate. 3. Damage to the water temperature sensor: This can cause the air-fuel mixture to become too lean, leading to abnormal engine operation.
