Remove any components obstructing access to the timing belt, such as the water pump or timing belt tensioner, using appropriate socket sizes.

4. Inspect and Replace Timing Belt

Remove the old timing belt by loosening the tensioner and carefully sliding it off.
Compare the old belt with the new one to ensure correct size and type.
Install the new timing belt, ensuring it is aligned correctly with the timing marks on the camshaft and crankshaft sprockets.
