Accessory Belt Tensioner Replacement

On a 1998 SC1 has anyone changed the accessory belt tensioner? How is this
done and is it a do-it-yourselfer job?

 

According to my Haynes*, you should have a similar engine to my '95
SW.

I changed out the tensioner a couple of years ago. It's a hand-tool
job, although the workspace is kind of tight.

Use a big crescent wrench (14 or 15mm, I forget which) on the
tensioner pulley bolt to rotate the tensioner arm and remove the belt.
Use a 10mm wrench to remove the two(?) bolts that hold the tensioner
to the engine block. On my car, I was able to get one with a socket
wrench, but I had to use a box-end on the other; not enough clearance
for the socket. Put the new tensioner on, rotate the pulley, replace
the belt (with a new one; personal preference) and you're good to go.
Total time; maybe fifteen to twenty minutes, maybe less. Depends how
difficult it is to break loose the bolts.

* - A worthwhile investment, IMO. I've bought one for every car I've
owned.

 

The tensioner adjustment bolt is a 9/16".
