How do you change the serpentine belt on a Toyota Corolla?

Answer 1

This is way easier on a Corolla than many other vehicles. The serpentine belt engages a number of cams, including a spring-loaded idler cam which keeps the belt tension constant--no need to adjust belt tension.

The idler cam is on a a lever which has a hex socket on one end which can be used to compress the spring and thus relax the idler cam. Use a socket wrench to give you the leverage and compress the spring. The belt can be easily removed and installed in this fashion.

There is a spot for a allen/hex wrench or a socket. The socket works much better and would more likely be in every ones toolbox. Since this is a " foreign " make , use metric sockets and a long handles breaker bar for ease of movement. Move it clockwise .Socket size is 19mm. Very very easy- will take you under 10 minutes to change the belt.

I have pictures , just don't know how to post them here.
