Toyota Genuine Parts 90916-A2005 Alternator and Fan Belt If you find that your 2AZ-FE engine needs it's drive belt replaced due to some cracking then this post may help. Here is what drivebelt cracks look like... This is what we will be working on today... Now, this job can be performed without removing the engine mounts like we are going to see but just wanted to show what it looks like when making it easier. The first step is to remove the bracket and "dog bone" motor mount... Now let's remove the other bracket held down with three 14mm bolts... With this mount and brackets out of the way it gives us plenty of room to get to that 19mm nut on the drive belt adjuster.... Just push down and then remove the old belt... Now just install the new belt and rout it in this fashion.....
