Does the 2015 Lexus RX 350 have a timing belt or chain?

The 2015 Lexus RX350 is equipped with a timing belt. Basically the timing belt is a rubber belt that controls camshaft and crankshaft rotation as well as the opening and closing of engine valves. The valves push the pistons down when the fuel is ignited. Without the timing belt, the valves don't open and close to allow the fuel to ignite and the car doesn't run.When You have a brand new timing belt that is in pristine condition, You will be able to experience an increase of acceleration immediately after You press the petal to the metal. Every manufacturer is different, but typically, the timing belt needs to be replaced every 60,000“100,000 miles.
