rate is only one bubble every fifteen seconds,
vacuum loss is usually insufficient to affect
the operation of the vacuum locking system
appreciably.
d. Isolating a Leaking Vacuum Part Using The
Leak-Down Testing Device
When a specific part has been isolated as the
leaking component, first check all hoses color-
coded red that attach to that specific part. Make
sure hose(s) are properly installed to the part
and that hoses are not split, thereby causing ap-
parent air leak.
After testing device has been properly installed
and storage tank recharged, watch glass tube in
testing device and proceed as follows:
1. If water rises in glass tube, storage tank is
leaking. Replace vacuum storage tank.
2. If bubbles appear in water, then air leak is
present at remote control valve or either door
lock selector valve.
3. Remove right and left front door hinge pillar
conduits.
4. Pinch right and left vacuum hose color-
coded red.
NOTE: This has eliminated the right and
left door lock selector valves from vacuum
system.
5. Check testing device. If bubbles continue to
appear in water, remote control valve is leaking.
(If bubbles stop, see Step 6).
6. If bubbles stop forming in testing device,
air leak is at either door valve. Discontinue
pinching left valve hose at hinge pillar.
7. Check testing device. If bubbles appear in
water, left door valve is leaking.
NOTE: Before replacing a door lock selector
valve, tighten screws on back of valve, then
recheck valve. If valve continues to leak, re-
place left door lock selector valve assembly.
8. If no bubbles appear in testing device after
discontinuing pinching of left valve hose, then air
leak is at right door valve. This may be shown
by discontinuing pinching of right valve hose at
hinge pillar. Bubbles will appear immediately in
water of testing device.
