Inspection of the Turbocharger and Charge Air Cooler
The turbocharger and charge air cooler should be inspected periodically.
Inspect the turbocharger and charge air cooler as follows:
NOTE: If any of the following conditions exist, it may be necessary to take
the vehicle to an authorized Detroit™ service outlet.
1. Inspect the turbocharger mounting, intake and exhaust ducting, and
connections for leaks daily.
2. Check the turbocharger lubricating oil inlet and outlet lines for leaks or
restrictions to oil flow.
3. Inspect for torn air inlet piping or boots and loose or damaged clamps.
WARNING: PERSONAL INJURY
To avoid injury from hot surfaces, wear protective gloves, or allow
engine to cool before removing any component.
4. Check the turbocharger for unusual noise or vibration and if excessive, stop
the engine and cease operation until the cause is determined.
5. Check the charge air cooler, duct work, and flexible connections for leaks.
6. Periodically inspect the charge air cooler for buildup of dirt, mud, etc. and
wash off using a mild soap solution.
Inspection of the Batteries
Inspection of the Batteries
Batteries should be inspected periodically. A good practice is to include the battery
inspection as part of the pre-start inspection.
Inspect the batteries as follows:
1. Inspect the overall condition of the batteries. Check for cracks in the battery
cases.
2. Inspect the cables, clamps and hold-down brackets regularly. If necessary,
clean and reapply a light coating of petroleum jelly. Damaged or corroded
parts should be replaced.
3. Check battery connections for corrosion and tightness. If necessary, remove
connections, wire brush any corrosion from terminals and cable ends and
reapply a light coating of petroleum jelly.
NOTE: If any of the above conditions exist it may be necessary to take the
vehicle to an authorized Detroit™ service outlet.
