How to Drain the Transmission Oil of BYD Song?
3 Answers
To drain the transmission oil of a BYD Song, first lift the vehicle and place a large container underneath to collect the waste oil. Use an appropriate screwdriver to remove the inner and outer transmission covers, being cautious as some transmission oil will flow out. After several minutes when most of the oil has drained, carefully remove the final oil pan, supporting it by hand as it still contains a significant amount of waste oil. Below is an extended explanation: 1. Transmission oil is a lubricant used to maintain the cleanliness of the gear system, lubricate and extend the lifespan of transmission components. It provides effective lubrication even in low temperatures and reduces oil loss under harsh operating conditions. Depending on the transmission structure, transmission oil is categorized into automatic transmission fluid (ATF) and manual transmission fluid. 2. Under 'severe driving' conditions, engine wear is more significant, requiring higher-quality oil. Therefore, it is recommended to shorten the oil change intervals to effectively protect the engine.
A while ago, I changed the transmission fluid for my BYD Song by myself, and the process was quite straightforward. First, park the car on a level surface, engage the handbrake, and use a jack to lift the front of the car, then place safety stands to ensure stability. Crawl under the car and locate the transmission drain plug, usually found at the bottom of the transmission. Use a wrench of the appropriate size to loosen the drain plug and prepare a large pan to catch the fluid to avoid spills. Once the fluid has completely drained, tighten the plug. Then, pour new transmission fluid through the fill port, remembering to use a dedicated funnel to prevent leaks. After refilling, start the engine and let the transmission run for a few minutes, then check the fluid level to ensure it's within the marked range. The advantage of DIY is cost savings, but be cautious of hot fluid to avoid burns, and make sure to choose the correct fluid type—my Song uses automatic transmission fluid (ATF), recommended to be changed every 60,000 kilometers to maintain lubrication. The whole process took me about two hours. It's fine to take it slow if it's your first time; the key is to have all the necessary tools ready to avoid getting stuck midway.
I've learned a lesson about changing transmission fluid. As a safety-conscious car owner, I must warn about the significant risks involved in this operation. For instance, if the car jack stands are unstable while lifting the vehicle, it could collapse and injure someone. Also, the fluid can be extremely hot right after a long drive, easily causing burns upon contact. Therefore, it's advisable to perform this task when the engine is cold or to wear thick protective gloves. The procedure involves first removing the drain plug to allow the old fluid to flow out completely, ensuring all impurities are expelled, before adding new fluid. For a BYD Song, don't guess the transmission drain location—always refer to the owner's manual for accuracy. Regularly changing the fluid can prevent wear and extend the transmission's lifespan, but if you're unsure, it's safer to leave it to professionals. I've seen cases where rushing the job led to dangerous oil spills everywhere. It's best to have an experienced friend guide you to ensure safety comes first.
