Troubleshooting
PROBLEM SOLUTION
Vacuum speed or level is reduced - Inadequate air supply. Must maintain 70psi
minimum throughout service.
- Air powered vacuum venturi has become clogged
with debris from dirty air supply.
Please contact Symtech for service procedures.
- Leak in the unit. Please contact Symtech
Corporation for service procedures.
Removal of coolant stops prematurely (before all
removable coolant is removed) - Cone has become dislodged or unseated from
radiator or Remote Reservoir tank neck. Check that
cone is properly seated and vacuum level of at least
20inHg can be obtained
Vacuum level of at least 20inHg is obtained but no
coolant is removed - Cone may be “bottomed out” on shallow radiator or
Remote Reservoir tank neck preventing coolant
flow. Cone may need to be trimmed back to
prevent “bottoming out”
Used coolant tank sight gauge is too dirty to view
level
- Sight gauge can be restored to new by emptying
used coolant tank and replacing sight gauge with new
17.5” X 3/8 O.D. length of new vinyl tube. Available
at Symtech.
Used coolant is leaking from bottom of unit
- Used coolant tank has been over-filled and used
coolant is escaping through relief valve of tank.
- Possible leak inside unit – contact Symtech
Corporation for service procedures
New coolant did not or can not adequately refill
vehicle - New coolant tank level or supply is empty or
coupler disconnected. Check level and replenish if
necessary. Check coupler for proper connection to
new coolant tank.
Coolant exchange in FLUSH mode does not occur.
- Recheck all connections, control panel valve
positions, and flow control valve positions and
retry. See pages 11 and 12
- Reverse RED/NEW and BLACK/USED hose
connections and retry. See pages 11 and 12
- Start vehicle allowing it to reach normal operating
