As the big brother of the Camry, the Avalon is Toyota's full-size sedan. The Avalon comes equipped with the same 3.0-liter, 210-horsepower V-6 that is available in the Camry and standard in the Lexus ES300.
The 3.0-liter engine utilizes two serpentine style belts. One that goes from the crank pulley around the alternator and the air conditioning compressor, and one from the crank pulley to the power steering pump.
The 3.0-liter engine utilizes a toothed timing belt. The service interval is 72 months or 90,000 miles, whichever comes first.
