The 2011 Lexus ES350 is equipped with a timing chain. It is recommended to change the air filter every 15,000 to 30,000 miles. The coolant should be replaced every 60,000 miles. Spark plugs typically need to be changed every 100,000 miles, except for copper spark plugs, which should be replaced every 30,000 miles. Engine problems are common and should be addressed promptly, such as oil leaks which require immediate repair. Loose gaskets should be tightened quickly, and if a spark plug pops off, it can cause engine issues. Excessive oil consumption may necessitate more frequent oil changes. Engine overheating is a serious issue that can lead to fires and potential car explosions.
