Is the crankshaft pulley bolt reverse threaded on a 1999 Toyota RAV4?

No, the crankshaft pulley bolt on a 1999 Toyota RAV4 is not reverse threaded; it is right-hand threaded. This means it tightens clockwise and loosens counterclockwise. When removing the bolt, it's important to use the correct tools and techniques, as it is typically torqued to a high specification.
