OPTIONAL SERVICE PROCEDURE.
To complete a service with the engine OFF, simply reverse the green and red
hose connections. The green hose will go to the upper radiator hose adapter and
the red hose will go to the adapter on the radiator.
Press “Service” and unit will transfer fluid until clean fluid tank is empty or
“Service” switch is turned off.
When doing an “Engine Off” exchange it is normal for the Clear-braided waste
hose to have air bubbles (SPITTING is caused by no vehicle pump action and the
CoolantClean3’s vacuum pump is drawing down the upper radiator tank). The
actual exchange will take a little longer than with the engine running, but there
will be no chance of overheating the vehicle.
Vehicles with vacuum controlled heater valves may not flush the heater in “Cold
engine” Mode.
WARNING:
DO NOT MIX DEXCOOL & ETHYLENE
GLYCOL BASED FLUIDS!!! Gelling will occur!!
Flush vehicle and or CoolantClean3 with water
between usage of these fluids. If you are changing
the Dexcool in a vehicle to ethylene glycol, flush the
vehicle with water prior to introducing the ethylene
glycol.
