MotorVac COOLANTCLEAN-1000 - Manual (Page 12)

Engine Cooling System Service Procedure
Follow this section to connect the COOLANTCLEAN 1000 unit to the
vehicle's radiator and or the upper radiator hose.
/!\ WARNING
Verify that engine and machine are both off before connecting or disconnecting
radiator hoses, lines or adapters.
Hot Coolant can spray out of pressurized lines when connecting or disconnecting.
Always wear safety goggles.
Wear chemical resistant gloves when connecting or disconnecting hot fittings and
adapters.
Wrap a shop towel around pressurized fittings and adapters when disconnecting.
Avoid exposure to flames, sparks, hot engine parts, and other ignition sources.
Explosion or flame or exposure to flammable liquid and vapors can cause injury.
Service Procedure
1. Check engine & coolant temperatures before removing any cooling system components or
repairing any associated items, let vehicle cool off if necessary.
CAUTION: Cooling systems may retain residual pressure after the vacuum procedures are
performed. Extreme care should be taken and proper protection worn when releasing the radiator
and overflow tank caps. Verify all pressure has been alleviated before opening hot cooling
systems; hot coolant under pressure can cause severe burns.
2.
Us the small hose adapter (p.n.060-1400) to connect to radiator overflow tube if residual pressure
needs to be removed from engine prior to removal of radiator cap. Attach the small hose adapter
to the overflow tube and briefly activate the vacuum procedure.
3.
For a “PARTIAL” service attach service hose to cone adapter, after removal of the radiator cap,
insert the cone adapter into the radiator fill neck. Set valves into vacuum position and turn on the
air control valve. Watch the upper radiator hose for maximum vacuum. Upper radiator hose will
be collapsed completely at this time. Repeat process on the overflow tank if necessary.
4. When you are ready to refill the vehicle the cone adapter should be in the radiator neck and full
vacuum should be applied to the system. (Hold position of valves) move the valve to the fill-
clean position and the vacuum in the system will draw fluid back into the engine from the
clean fluid tank. When the flow stops the cone adapter can be removed from the radiator. To
‘top-off’ hold the wand securely at the radiator cap opening (allowing trapped air to escape) and
turn on the air pressure to the pump. Turn off air valve when full. Replace the radiator cap. Refill
overflow tank if required. “Partial” service is now complete.
