I have a bad pulley on a '96 Corsica tensioner. I see that I can replace
the pulley, but can it be done without removing the tensioner? It looks
like the pulley has spun out of the bearing. I can't see down in there very
well, and I can't see a bolt to remove the pulley so it's either hidden from
view right now, or on the back side of the tensioner. If it is on the back
side, I don't see any way of replacing it without pulling the tensioner
which may mean pulling out the motor mount and/or water pump first just to
get a damn wrench on it. If I have to do all of that it makes more sense
just to replace the whole assembly.
Does anyone have any experience with this? The same tensioner seems to fit
a number of 3.1L GM autos.
Take the vehicle to your favorite garage and get a free estimate. You
may find they have the right tools and your repair won't be as
expensive as you think. This type of repair can be "a knuckle buster".
I would consider that, but I'm nearly 50 miles from the city and the tow may
be more than the repair. The belt is off, so there's no possibility of
driving it there, and I don't want to drag it there because I'd have to have
my wife brake the Corsica and I don't want to replace the bumper on my
Yes you can replace just the pulley, not in the vehicle though, BUT if
that is the original tensioner assembly you would be better served to
replace the entire tensioner. You will spend about 30 dollars more but
you will get a new pulley and new tension spring as well. Also some of
the tensioners used a left hand threaded bolt for the pulley. I don't
remember off hand if yours is one though, sorry.
The tensioner isn't hard to remove itself, one bolt through the center
is all that holds it.
Jack up the right front, pull the tire off then remove the splash cover
from the wheel housing. Use a box end wrench to remove the bolt and drop
the tensioner down to the left to remove it. While you are there make
sure the belt didn't do any damage to the wiring to the crankshaft
Thank you Steve,
That sounds much better than fighting the motor mount and still being short
on room. I'm sure it's the original so I will plan on replacing it all. It
looks like there's no way to get a new belt in there without pulling the
motor mount out too, but that should be easy enough once the car is back on
the ground. Sometimes I wish we still used horses...... except when it
rains, or snows, or it's too hot or too cold, or windy, ha-ha. I guess I
love cars after all.
