Many engines also require special tools when changing a timing belt or chain. At the very least, you should have a belt tension gauge to make sure the tension on a timing belt is correct. Special camshaft positioning tools (or a bolt or pins) may also be required on some dual overhead cam engines to hold the cams in place while the belt or chain is replaced.


Here are just a few of the special OEM timing tools that may be required:
