7. Align the protector on the body, and attach it securely as
shown.
8. Prepare the nozzle of the sealant gun so that it has a flange
that can run along the edge of the glass and a V from which
the sealant can flow. Once the primer is dry, apply the seal-
ant around the entire circumference of the glass to fill the
gap between the dam and the edge of the glass with a ridge
of sealant
12mm (0.47 in) high.
Keep the bead of sealant smooth and even, reshaping it
where necessary with a spatula.
9. Lift the glass into place. Push it in lightly toward the vehicle
to compress the sealant.
Caution
l Open the windows to prevent the glass from being
pushed out by air pressure if a door is closed.

10. Align the upper windshield molding on the body as shown,
and push the molding into place along the top.
Note
l Install the molding before the sealant has hardened.
11. Check for water leaks. If a leak is found, wipe the water off
well and add
sealant (BOO1 77 739) where needed.

Note
l If the glass is not to be reused, a tool like that shown
in the figure may be used.
Insert the blade in the sealant, and pull on the bars.

1. Cut away the old sealant with a razor knife so that 1 to 2mm
(0.04 to 0.08 in) of sealant remains around the circumfer-
ence of the frame. If all the sealant has come off in any one
place, apply primer after degreasing, and allow it
approx.
30 minutes
to dry. Then put on new sealant to create a
2mm (0.08 in) layer.
2. Carefully clean an area 5
cm (1.97 in) wide around the cir-
cumference of the glass and the bond on the body.
3. Bond a new dam along the circumference of the glass
7mm
(0.28 in) from the edge.
Caution
l Bond the dam securely and allow it to dry.
4. Apply primer with a brush to the bonding area of the glass
and the body, and allow it to dry for
approx. 30 minutes.
Caution
l Keep the area free of dirt and grease. Do not touch
the surface. If primer gets on the hands, remove it
immediately.
5. Install the spacers onto the body.
Caution
l Damaged spacers must be replaced.

Thermal Protector Replacement
1. Removal of discharge valve body
Remove the bolts and carefully remove the discharge valve
body. .-
2. Removal of snap ring and thermal protector
Note
l When removing the thermal protector, do not pull
the harness wires but push the protector out from
its back side.
23UOUX-028 3. Installation of thermal protector
1) Check that the O-ring groove is free from foreign matter.
Apply compressor oil to the O-ring and properly fit it in
the groove.
2) Before installing the thermal protector, check it for con-
tinuity.

3) Install the snap ring so that its chamfered edge side faces
the thermal protector (the non-chamfered side faces out-
ward) as shown left.
Make sure the snap ring is seated securely in its groove.
Note
l Install the thermal protector so that its two lead wire
outlet sections are horizontal as shown left.
