The troubleshooting and diagnostic sections help identify common engine problems including difficult starting, failure to start, reduced power, irregular running, excessive fuel consumption, overheating, low oil pressure and abnormal engine noise.
Information is included for diagnosing black, white and blue exhaust smoke. These symptoms may be caused by fuel-system faults, turbocharger problems, incorrect injection control, worn internal components or cooling and lubrication faults.
The electronic engine-management section covers the engine control unit, sensors, actuators and related testing procedures. Diagnostic fault-code information helps technicians locate electrical and electronic system problems accurately.
The fuel-system section includes the fuel supply circuit, high-pressure components, injection equipment and electronic controls. These procedures can assist with diagnosing poor starting, uneven running, reduced engine output and excessive smoke.
Turbocharger and air-intake procedures cover inspection, testing and servicing. Correct turbocharger operation is essential for maintaining engine performance, fuel economy and emissions compliance.
Cooling-system information covers the water pump, thermostat, coolant passages and associated components. Proper maintenance helps prevent overheating, cylinder-head damage and premature engine wear.
The lubrication section covers the oil pump, filters, oil cooler, oil passages and pressure testing. Correct lubrication is essential for protecting the crankshaft, bearings, pistons, camshaft and turbocharger.
Cylinder-head procedures include removal, dismantling, inspection, valve servicing and installation. Information is provided for checking valves, seats, guides, rocker assemblies and related components.
The lower-engine section covers the cylinder block, liners, pistons, connecting rods, crankshaft, bearings, camshaft and timing components. Standard measurements and repair limits help determine whether components can be reused or require replacement.
Detailed dismantling and reassembly procedures are supported by tightening sequences, torque figures, clearances and adjustment data. Following the correct specifications helps ensure reliable engine performance and long service life.
