MotorVac COOLANTCLEAN III - Manual (Page 15)

Service Procedure, (Continued)
13.
Press the unit’s power switch to the SERVICE position (RIGHT). Continue until the coolant level
has reached the middle of the radiator filler neck. When the proper level is reached press the
unit’s power switch to the OFF position (CENTER) to stop unit. Re-install radiator cap securely.
Start vehicle’s engine & press the unit’s power switch to the SERVICE position (RIGHT).
14.
With engine running, continue with the service until the coolant in the unit’s tank has been
depleted or until the coolant draining from the clear braided drain hose is clean. When either one
of these conditions have been met, press the unit’s power switch to the OFF position (CENTER)
to stop unit. NOTE: If the upper radiator hose is collapsing during the service or the
overflow reservoir is being drained, increase the engine rpm. This increases the flow thru the
vehicles’ water pump assembly.
Turn off vehicle’s engine at this time.
NOTE: When the unit’s tank has been depleted of fluid a low level light will illuminate & the low
level alarm will sound. At this time the unit automatically reverts to a “bypass” mode and the
vehicle’s cooling system flow will simply pass through the unit and return to the vehicle in a
closed loop fashion. Turning off the unit will disable the audible warning.
15. Remove the clear braided drain hose from the waste tank nipple or shop’s waste tank or
receptacle and insert an adapter and direct it into the vehicle’s coolant recovery tank. Press unit’s
power switch to the VACUUM position (LEFT) to fill the recovery tank. When recovery tank has
reached the proper or acceptable fluid level, press the unit’s power switch to the OFF position
(CENTER). NOTE: This step will also alleviate any residual pressure remaining in the system to
provide safe disconnection of the unit’s adaptors and connections when the service is complete.
16.
Verify that the unit’s pressure gauge reads, “zero”. Carefully remove the radiator cap. Coolant
level should be lower that the upper radiator hose connection point. If level is not acceptable
insert the unit’s clear braided hose into a suitable collection container. (See note). Continue with
power switch in the VACUUM position (LEFT) until coolant level is acceptable. NOTE: During
this procedure, the clear braided hose will be draining clean coolant from the vehicle. You may
choose to save this “clean” coolant in an acceptable storage container for future use or direct the
flow into the shop’s waste receptacle.
17.
Disconnect unit’s lines & adaptors from vehicle and re-connect vehicle’s upper radiator hose and
overflow tank hose. Tighten hose clamps securely and inspect connections with system
pressurized.
18.
Re-connect an open adapter to the unit’s GREEN / new coolant hose & insert hose into the
vehicle’s radiator filler neck, press the unit’s TOP OFF button to the ON position to fill or top-off
the coolant in the radiator. Repeat procedure to fill or top-off the radiator overflow tank. Adjust
radiator and overflow tank levels as per manufacturer’s specifications.
19.
Start engine with radiator cap removed. Re-check and adjust radiator & overflow tank levels as
needed. Replace radiator cap securely when procedure is complete.
20.
To empty the waste fluid tank you must switch the hose connections at the waste tank Nipple.
Disconnect the clear-braided hose and put an adapter into the coupler. Direct the clear hose into
the shops waste container. Connect the RED hose coupler to the waste tank nipple. Turn on the
empty waste switch. The pump should stop when the tank empties.
