In the 2016 Chevy Malibu, the o2 sensors are located both upstream and downstream of the catalytic converter. Various engine issues may arise, such as spark plug dislodgement leading to engine problems, loose gaskets requiring prompt tightening, and oil leaks that should be promptly addressed. An alarming concern is engine overheating, which can result in fires and even the vehicle exploding. Excessive oil consumption may necessitate more frequent oil changes than anticipated. It is recommended to change the coolant every 60,000 miles, replace the air filter every 15,000 to 30,000 miles, and change spark plugs every 100,000 miles, except for copper spark plugs which need replacement every 30,000 miles.
