Rosco CSV - Replace Radiator Hoses; Diesel Exhaust Fluid (DEF) System

Replace Radiator Hoses
Radiator hoses should be replaced if worn or frayed.
Replacement parts are listed in Section 7, Illustrated
Parts List (IPL).
This procedure should only be
performed when the equipment is not operating.
DO NOT remove the radiator cap while
the engine is still hot. The radiator is under pressure.
Removing the cap could cause serious injury.
1. Turn off ignition, remove key, and allow the engine to
cool down before proceeding:
2. Remove the radiator surge tank cap.
3. Drain radiator into a suitable container (5.5 gallons
or 20.8 liters).
4. To remove upper hose, loosen the two hose clamps
and disconnect. If clamps are not damaged, retain
for installation.
5. To remove lower hose, loosen the two hose clamps
and disconnect. If clamps are not damaged, retain
for installation.
6. Install new hoses in reverse order of procedures
above.
Diesel Exhaust Fluid (DEF)
System
The DEF system is an efcient, effective means of
ltering dirt and other contaminates for optimum
machine performance and reducing air pollution from
exhaust emissions. A sensor on the DEF tank header
monitors the level, temperature and quality of DEF in the
tank. The header is mounted on top of the DEF tank and
provides ltered DEF supply from the tank to the after
treatment DEF dosing unit. Both the DEF tank header
and dosing unit have serviceable lters that require
cleaning or replacement. Fill the DEF tank with DEF
uid at any gas station and be sure to keep the tank full.
(Figure 5-17)
Figure 5-17. DEF Tank
The DEF system will automatically purge the uid
from the system after shutting down the machine and
requires no intervention from the operator.
NOTE: Check the ttings around the DEF tank
header for leaks or any signs of damage
regularly. DEF leaks will leave a white
deposit around the ttings.
DO NOT pressure wash or steam
clean this unit to avoid damage the components. Use
compressed air to remove any loose debris.
DEF contains urea, therefore, wear
safety glasses when performing these procedures.
DO NOT get the substance in your eyes. In case of
contact, immediately ush eyes for a minimum of 15
minutes.
Before servicing any component in the DEF system,
allow the DEF system to purge. You will hear the
pumping noise as the system completes the purge cycle
automatically after shutting down the engine.
1. Shift transmission into neutral.
2. Apply the parking brake.
3. Shut off the engine. Wait at least ve minutes after
shutting down the engine for the after treatment DEF
dosing unit to complete its automatic purge cycle.
DO NOT disconnect battery until the
purge cycle has completed to prevent damage to the
unit.
4. Place battery master switch in the OFF position.

It’s important to service the DEF
system in a clean, dust-free environment to prevent
contamination in the DEF tank that can damage the
after treatment DEF dosing unit.
