Operating Instructions for Starting the Engine

When preparing to start a new (or newly overhauled) engine, which has been in

storage, perform all of the operations listed below. Failure to follow these

instructions may result in serious engine damage.

Be sure you are familiar with all of the instruments, gauges and controls which are

needed to operate the engine.

Note especially the location and function of the following:

• Oil pressure gauge

• Low oil pressure warning light

• Coolant temperature gauge

• High coolant temperature warning light

• Water-in-Fuel warning light in the side of the fuel filter module

• Air restriction indicator

Watch for any signs of engine problems when starting or driving. If the engine

overheats, uses excessive fuel or lubricating oil, vibrates, misfires, makes unusual

noises or shows an unusual loss of power, turn the engine off as soon as possible

and determine the cause of the problem. Engine damage may be avoided by a quick

response to early indications of problems.

When starting the engine in cold weather, Refer to section "Cold Weather

Operation"

System Checks

Perform the following system checks before starting for the first time.

Checking the Cooling System

Check the cooling system as follows:

1. Make sure all drain cocks in the cooling system are installed (drain cocks are

often removed for shipping) and are closed tightly.

2. Fill the coolant overflow surge tank with Detroit™ Genuine Coolant until

coolant level stays between the low and full coolant marks on the tank.

3. Entrapped air must be purged after filling the cooling system. To do this,

allow the engine to warm up with the pressure cap removed. With the

transmission in neutral, increase engine speed to 1000 rpm and add coolant

to the surge tank as required.

4. Check to make sure the front of the radiator and charge air cooler (if

equipped) are unblocked and free of debris.
