Reasons for the Coolant Not Circulating in the Zhonghua Junjie?

[VanAmy]

There are issues with certain hardware components in the cooling circulation system. Below is relevant information about the Zhonghua Junjie: 1. Design: The Junjie incorporates designs from Italy's Pininfarina, blending Western dynamism and elegance with Eastern smoothness and grandeur. This highly anticipated model is a Wagon variant developed on the Zhonghua Junjie platform by the globally renowned Pininfarina Automotive Design Center; 2. Manufacturing: During production, Brilliance Auto strictly adheres to BMW manufacturing standards, employing BMW engineers to oversee the production process. Even in critical processes, it shares production lines with Brilliance BMW, ensuring that the quality of this Zhonghua Junjie Wagon can rival that of renowned European automotive brands.

I drove a Brilliance Junjie for several years. The most common issue with water not circulating is a faulty water pump. When the rotating part wears out or the bearing is damaged, the coolant can't be pushed effectively. Another problem is a faulty thermostat—if it gets stuck in the closed position, the fluid only circulates within the engine and doesn't reach the radiator, causing the temperature to spike. Insufficient or dirty coolant can also cause this issue; too little fluid means inadequate pressure, or pipes clogged with rust and debris can impede flow. Additionally, air bubbles in the system can create an airlock, requiring bleeding and inspection. If the engine heats up but the hoses don't feel warm, or if there are unusual noises or abnormal water flow sounds, it's likely a water pump or thermostat issue. Replacing the antifreeze and cleaning the radiator during every maintenance session can prevent major repairs. Never delay fixing these issues, or the engine may overheat and suffer severe damage like cylinder scoring, leading to total failure.

The issue of water not circulating sounds scary. I once experienced a sudden surge in water temperature on the road, which almost caused a major problem. Common causes include a malfunctioning water pump, a faulty thermostat, or air trapped in the cooling system blocking the flow. For older models like the Zhonghua Junjie, the water pump is prone to aging and leaking, and the thermostat spring may fail to open or close properly, causing the coolant to get stuck and not circulate. Sometimes, corroded or clogged pipes, or insufficient coolant can lead to the same issue. If the dashboard temperature gauge alerts you, immediately stop the car, turn off the engine, and let it cool down. Don’t force it to run and risk damaging the engine. Check the coolant level yourself—if it’s too low, top it up to the marked line, and see if the fan is running. Safety first—if you spot a problem, take it to a professional repair shop right away. Don’t skimp on repairs and risk an accident. Regularly changing the coolant every two to three years and cleaning out deposits will make things much safer.

My Brilliance once had a coolant circulation issue. Simply put, it's usually caused by a failed water pump or a stuck thermostat. If the pump can't rotate, coolant won't flow; if the thermostat doesn't open, the radiator won't receive coolant. Low coolant level or contaminated fluid are also common causes - insufficient pressure from low fluid or blockages from rust debris/air bubbles all hinder circulation. You can first check the reservoir level under the hood - top up with antifreeze if below the line. If pipes feel hot on one end and cold on the other after cooling down, it indicates thermostat problems. Address minor issues promptly to avoid costly major repairs. Remember to maintain the system regularly using qualified antifreeze to prevent corrosion and extend lifespan.
