Belt starting to shred on 4cyl 1999 Magna. Have new belt but could someone post pics of how this is done and with instructions please

Not many owners of the 4 cylinder on this forum, so this is generic info:
(You may get someone to post specific pics and instructions, later.)

Locate idler/tensioner.
Work out how the tensioner works. Back off the central nut, unwind tensioner until the belt can slip off.
Take old belt off, put new belt on. Make sure the ribs sit on the various pulleys correctly.
Adjust belt tension with tensioner. The ribbed flat belts need to be fairly tight.
Tighten centre nut of tensioner.
Test drive. Check belt tension after a few 100 km.

EDIT: If the alt belt is behind the power steering belt, is will have to come off first.
I was going to buy a Magna with the 4 cylinder engine at one stage, and looked for the workshop manual on line, but haven't found one yet.

Thanks for your input Max. Put car on ramps. Had a good look. Job was easier than anticipated. Found some old muscles that protested a bit, but only took 1/2 hr, so all well. Thanks again.
