Baojun 730 Difficult to Start When Cold
1 Answers
Baojun 730 generally has difficulty starting when cold. The following checks should be performed: 1. Remove the spark plugs and inspect them to see if carbon deposits need to be cleaned or replaced; 2. Check the fuel injectors for carbon buildup and clean them. If it's time for maintenance, proceed with servicing; 3. Another possibility is a faulty cold-start signal from the coolant temperature sensor (this issue can be identified by diagnostic tools with corresponding fault codes). Most cases of cold-start failure are caused by excessive carbon deposits. It is recommended to use high-grade synthetic oil after maintenance and repair. High-quality engine oil offers advantages such as anti-aging and high-temperature resistance, thus reducing carbon buildup. Generally, during the warm-up process at idle, the engine speed should first return to the normal idle level. This process should take at least 30 seconds. The vehicle can then start moving. However, within the first 200-300 meters, the driver should avoid pressing the accelerator too hard. The general practice is to wait until both the coolant temperature and engine speed reach the required levels before accelerating. Warming up the car in winter is an important task, as a car that hasn't been properly warmed up can damage the engine and, over time, reduce the vehicle's lifespan.
