Volvo Maintenance Hints for 7xx/9xx - Bill Garland's Nuclear ...

[Tip from Ed Kucinski] Just a reminder, when changing oil, keep the oil off the rubber motor mounts. Especially
when changing the oil filter, some tends to get down there. Wipe it clean. Its the oil that deteriorates the rubber
and speeds failure.
Changing Engine Mounts on 960/90 Series Vehicles. [Procedure by Walt Posluszny]
-Lift vehicle and set on jack stands.
-Remove the belly pan
NOTE : The motor mount actually consists of two pieces, the rubberized mount itself and the metal bracket it is
attached to. However, it is removed and installed as a single unit.
Passenger side (straightforward and fairly easy):
Removal:
FROM THE TOP:
-Remove top nut (15mm)
-Remove rear most nut on the bracket (13mm)
FROM THE BOTTOM:
-Remove front inboard nut (13mm) on the bracket with a box or open end wrench.
-Remove bottom mounted bolt from the bottom of the bracket thru the chassis. This bolt is 12mm
for some reason, and you will need to move the steering arm boot to get a socket on this bolt from
below the bracket/chassis.
-Once all three nuts and the one bolt is out, carefully jack up the engine and chock tthe engine with
wood blocks for safety (you don’t want the engine to come down on your hand when you’re taking
out or putting in the mount).
-The mount will now come out to the front.
-Remove the mount from the bracket by removing the one nut at the bottom of the mount (15mm
IIRC)
Installation:
-Install new mount on old bracket
-REVERSE above removal procedure torquing the top (15mm) bolt to 37 ft./lbs. (there were no
specs to be found for the other nuts/bolts).
Driver’s side (a bit more challenging)
The procedure for removing the Driver’s side is the same as the Passengers’ side except for the following:
Removal:
I couldn’t even see the mount from above so I decided to remove the following items to make the
R&R even possible.
FROM THE TOP
-I removed the aluminized cardboard hot air tube from the air box to the manifold. This facilitated
now seeing the top bolt (15mm). I was able to use a very long extension to get to it from the top
now.
-To get the above hot air tube out I actually removed the top of the air box to make life a little
easier and to give me more room to maneuver.
FROM THE BOTTOM
-I was unable to get a socket on the rear bracket nut (13mm). The metal power steering line was in
the way. So from under the vehicle, from behind the front tire I reached in and kept bending the
