2.Remove the radiator cap. Fill the radiator with coolant
until coolant starts to appear from the previously
removed hose at the EPR. Reinstall the hose back
onto the EPR and continue to fill radiator with cool-
ant.
3.With the radiator cap still removed, start the engine and
run until the thermostat opens. The thermostat
opens at 170° F (77° C), which can be checked
using the JLG handheld analyzer.
WHILE ENGINE IS RUNNING, AIR AND/OR STEAM MAY BE PRES-
ENT COMING FROM THE RADIATOR. THIS IS NORMAL.
4.After running the engine for 5 minutes after it has
reached operating temperature, shut the engine off
and continue to step 5.
WITH THE ENGINE RUNNING OR WHEN SHUTTING OFF THE
ENGINE, SOME HEATED COOLANT MAY SPILL OUT DUE TO AIR
"BURPING" OUT OF THE SYSTEM WITH THE RADIATOR CAP OFF.
5.Next, verify that the 2 coolant hoses on the EPR are
warm. If they are not warm repeat step 3 and 4, oth-
erwise continue to step 6.
A PROPERLY PURGED COOLING SYSTEM WILL YIELD A WARM
UPPER RADIATOR HOSE AND A WARM EPR HOSE. IF THE UPPER
RADIATOR HOSE AND/OR EPR HOSE ARE NOT WARM TO THE
TOUCH AFTER THE ENGINE HAS RUN FOR 5-8 MINUTES AFTER
REACHING OPERATING TEMPERATURE, THE SYSTEM MAY STILL
CONTAIN AIR. IT MAY BE NECESSARY TO REPEAT THE ABOVE
STEPS.
6.Fill radiator with coolant as needed and install the radi-
ator cap. Next, remove the cap off the coolant recov-
ery bottle and fill just below the HOT FULL line and
reinstall the caps.
