HOW-TO SECTION
NOTICE:
To avoid cover or vent dap damage,
do not use tools to tighten the vent
cap.
NOTICE:
Do not allow the fuel level in the
see-thru cover to fall below the top
of the collar, since this may lead
to interruption of the fuel flow and
engine stalling.
2. Start the engine and allow the
lubrication system to reach its
normal operating pressure, then
increase engine speed to high idle
for 2 to 3 minutes.
3. After the air is purged and with
the engine still running, loosen
the vent cap on the filter cover.
The fuel level in the cover will
start falling. When the fuel level
falls to the top of the collar on the
Fuel Pro cover, tighten the vent
cap quickly by hand.
NOTE:
If the engine fails to start after
replacement of fuel filters, the fuel
system will require priming with tool
J 5956 or equivalent. Authorized
Detroit Diesel distributors are properly
equipped to perform this service.
How to Select Coolant
This section covers selection of the
required coolant for Series 60 engines.
Definitions
To help ensure complete
understanding of the information, the
definitions of the following terms are
provided:
Antifreeze — Ethylene glycol
or propylene glycol containing a
corrosion inhibitor package and which
meets an appropriate heavy-duty
specification (i.e., TMC RP-329 for
ethylene glycol or TMC RP-330 for
propylene glycol).
Coolant — The fluid mixture
circulating in the engine cooling
system, typically a mixture of 50%
water and 50% antifreeze.
Drop–Out — Precipitated sludge or
deposit formation on cooling system
components.
Fully Formulated Antifreeze —
Contains all the necessary inhibitors
to protect a diesel engine, and does
not, therefore, require a pre-charge of
SCA before its first use.
Initial–Fill Coolant — The coolant
that is used in a new or rebuilt engine,
or any time the cooling system is
emptied and then refilled with coolant.
