This tool can only be used one time.
Do not open the high pressure fuel system without allowing the fuel
system to purge. After the engine has shut down, allow the fuel system
to purge for ten minutes. This operating fuel system contains high
pressure. Exposure to high pressure fuel can result in personal injury.
Note: Use Caterpillar Electronic Technician (ET) to verify that the fuel system pressure is at zero
before opening the fuel system.
Note: Use Tooling (A) after any fuel line has been disconnected.
1. Ensure that number four piston is at the top center position on the compression stroke. Refer
to Systems Operation, Testing and Adjusting, "Finding Top Center Position for No. 4
Piston".

Exhaust Gas Recirculation Valve - Remove and Install
SMCS - 108N-010
Removal Procedure
Personal injury can result from hot coolant, steam and alkali.
At operating temperature, engine coolant is hot and under pressure. The
radiator and all lines to heaters or the engine contain hot coolant or
steam. Any contact can cause severe burns.
Remove cooling system pressure cap slowly to relieve pressure only
when engine is stopped and cooling system pressure cap is cool enough
to touch with your bare hand.
Do not attempt to tighten hose connections when the coolant is hot, the
hose can come off causing burns.
Cooling System Coolant Additive contains alkali. Avoid contact with
skin and eyes.
NOTICE
Care must be taken to ensure that fluids are contained during
performance of inspection, maintenance, testing, adjusting, and repair
of the product. Be prepared to collect the fluid with suitable containers
before opening any compartment or disassembling any component
containing fluids.
