How do you change the motor mounts on a 1989 Chevy Blazer S10?
You first have to unbolt the engine from the motor mounts and
unbolt the engine from the transmission. You then will remove the
motor from the truck to make replacing the mounts easier. The
mounts should each be held down by four bolts going into the frame.
Remove or cut these bolts to remove the old mounts. You can then
install the new motor mounts.
if you don't care for making it "easier": you can jack the truck
up on one side, put stand under pulley on crank, lower truck onto
it, as you lover or raise the jack you'll have good control over
go to local parts store and just read the book there.
if it gets real bad , have vehicle put on a lift, take off the
wheel, use long extension on impact driver by placing it in a wheel
well. while holding motor up on tall stand.
