The 4EFE engine is a 1.3-liter, 16-valve, four-cylinder engine used in some Toyota models. Here is a general method for setting the timing on this engine:

Remove the timing belt cover to access the timing belt and related components.

Rotate the crankshaft until the timing marks on the crankshaft pulley are aligned with the marks on the engine block. The timing marks may be indicated by a groove or notch on the pulley and a mark on the engine block.

Check the alignment of the camshaft timing marks. There should be timing marks on both the camshaft sprocket and the cylinder head. These marks should be aligned with each other.

Loosen the timing belt tensioner and adjust the timing belt tension to the manufacturer's specifications.

Rotate the engine a few times to ensure the timing belt is properly seated and tensioned.

Reinstall the timing belt cover and any other components that were removed.

Start the engine and check the timing with a timing light. The timing should be adjusted to the manufacturer's specifications.

It's important to note that some vehicles may have specific procedures or requirements for setting the timing, so be sure to consult the owner's manual or a professional mechanic for guidance. Additionally, timing belt replacement is recommended at regular intervals to prevent potential engine damage due to a broken or stretched timing belt
