Preparation for Cleaning the Tubes and Manifold
1.
On the manifold, remove the Solenoids A, B, C, and D from the 4 Control Valves
located on the manifold. Do not remove Solenoid E.
See Figure 9-23.
2.
GM Control Valve Assembly and Components.
See Figure 9-24.
3.
Remove the RED Cap from the Solenoid Base and the Nameplate/Retainer and keep
for reuse.
See Figure 9-25.
4.
Slide the Solenoid off the Solenoid Base. Do not remove the flexible conduit from the
Solenoid.
5.
Remove the Spring Washer from the Solenoid Base and keep for reuse.
6
Use a 1” wrench to remove the Solenoid Base from the Valve Body. Keep the Solenoid
Base, the Core Assembly and Body Gasket for reuse.
See Figures 9-26
.
7.
Place the empty Solenoid Base inside the Solenoid, then attach the RED Cap.
Do this for all four Solenoids.
See Figures 9-27 and 9-28.
WARNING
: The Solenoid Base MUST BE INSTALLED inside the Solenoid so the magnetic
field around the Solenoid will not breakdown when power is applied to the Solenoid.
8.
Move the four Solenoids out of the way of the manifold.
See Figure 9-29
.
9.
The Manifold is now ready to clean.
See Figure 9-30
.
10. Install the provided Blowout Tube with the clear plastic tubing attached to the
discharge side of the Vacuum Pump. Tighten the 45° nut on the fitting hand tight.
See Figure 9-31
.
CAUTION
: Do not use any thread sealing compound when assembling the 45° flare
nuts on the tubes
