What are the reasons for the high coolant temperature in the BYD S6?

The reasons for the high coolant temperature in the BYD S6 may include thermostat failure, oil leakage, etc. Here is a detailed introduction about BYD automobiles: 1. Overview: BYD is a Chinese automotive brand, founded in 1995, mainly producing commercial vehicles, family cars, and batteries. Starting with a team of just over 20 people, it grew to become the world's second-largest rechargeable battery manufacturer by 2003, and in the same year, it established BYD Auto. 2. Others: The design of BYD vehicles incorporates both advanced international trends and aligns with the aesthetic concepts of Chinese culture. The new BYD logo will no longer use the original blue and white color scheme; the pattern has been changed to an elliptical shape, incorporating light and shadow elements.

I've been driving my BYD S6 for over three years, and the most frustrating issue is the coolant temperature getting too high. Common causes include insufficient coolant, possibly due to an unnoticed leak; a clogged radiator that's too dirty, especially in summer when flying insects easily block airflow; a broken fan that won't spin and can't dissipate heat; a stuck thermostat that won't open, affecting circulation; and an aging water pump that can't push the coolant, leading to temperature rise. Once, during a long-distance drive, the temperature suddenly spiked because the fan wiring came loose. I had to stop immediately to check, refill the coolant, and cool it down, or the engine might have been ruined. I recommend regularly checking if the coolant level is between the min and max marks, cleaning debris from the radiator surface periodically, and addressing any issues promptly by visiting a professional repair shop. Spending a little now can save you from bigger troubles later.

Overheating in a BYD S6 is no joke—it's a serious safety concern. Common causes include cooling system leaks, such as aging or cracked hoses leading to low fluid levels, radiator corrosion clogging water flow, a faulty fan motor failing to activate during high temperatures, or a malfunctioning thermostat unable to regulate opening and closing. I recall my uncle's car nearly smoking due to a worn-out pump shaft hindering circulation—luckily, he pulled over and turned on the heater for emergency cooling. Remember: if the dashboard alarm goes off, don't push it—slow down, turn off the engine, and inspect. Routine maintenance is crucial, like cleaning radiator fins quarterly to prevent dust buildup, avoiding improper modifications that add strain, and promptly fixing hidden issues for peace of mind.

Coolant temperature being too high in the BYD S6 is often due to overlooked simple issues, such as low fluid levels from leaks or evaporation without replenishment, radiator blockage preventing air flow and unresponsive fans, a thermostat stuck in the closed position not opening, or a failed water pump. I test the coolant concentration every six months to prevent corrosion and clean the exterior of the radiator, making it a habit to avoid problems. Additionally, air bubbles in the system can also affect flow, so it's important to bleed the system when adding fluid. Addressing small issues prevents big problems; don't wait for an alarm to act, reducing risks and saving money.
