Prevents stripped threads and warped cylinder heads.
The Toyota 5A-FE is a non-interference engine. This means that if your timing belt snaps while driving, the pistons will not strike the valves. While it will leave you stranded on the side of the road, it will not destroy your engine! Always cross-reference your PDF manual's timing mark diagrams when installing a new belt to ensure perfect engine timing. 5afe engine repair manual pdf better
