★ Top Answer
The 2001 Toyota RAV4 has four oxygen sensors. It's recommended to change the coolant every 60,000 miles, while the air filter should be replaced between 15,000 to 30,000 miles. Spark plugs usually need to be changed every 100,000 miles unless they are copper, in which case they should be replaced every 30,000 miles. Engine issues can arise from various problems, such as a loose gasket or a spark plug coming off. Oil leaks should be promptly fixed, and engine overheating is a serious concern as it could lead to fires and explosions. Excessive oil consumption may also necessitate more frequent oil changes than usual.

The oxygen sensor for a 2001 Toyota RAV4 depends on the engine size. You can find these sensors either under the hood or beneath the car. They're attached to the exhaust pipe, positioned in front or behind the catalytic converter. The front sensors, also known as upstream sensors, monitor oxygen levels in the exhaust system, while the rear sensors (downstream) are situated after the catalytic converter.
