When replacing coolant, use distilled water and the exact concentration specified by the OEM manual to avoid corrosion or scale buildup. Periodically purge the cooling system of air pockets by running the engine with the radiator cap removed until steady bubbling ceases, then re-cap and recheck the system pressure. Fuel system troubleshooting and injector service The fuel system delivers the correct quantity of clean fuel to the engine while maintaining proper pressure. Begin with a surface inspection of all fuel lines for cracking, brittleness, or loose connections, particularly at the fuel filter, injectors, and the fuel pump. Use a flat, stable surface to check for fuel leaks around fittings and seals; even small drips can indicate worn O-rings or loose clamps. When diagnosing fuel pressure, connect a calibrated gauge to the service port and compare readings with the OEM specification for the LT160H42GBV; fluctuations can signify a failing pump, clogged filter, or faulty regulator. If fuel delivery appears inconsistent, inspect the high-pressure rail and injector sleeves for deposits or carbon buildup that can disrupt spray patterns. For injector service, remove the injectors following the factory torque sequence and clean the intake ports to avoid introducing debris into the combustion chamber. Use a professional-grade injector cleaning kit and a controlled solvent to remove varnish and deposits without damaging seals. After cleaning, inspect the nozzles for excessively worn or blocked orifices and replace any injector that does not meet spray pattern and flow specifications. Reassemble with new O-rings and ensure all connections are free of leaks. When reinstalling, perform a short idle and light-load test to verify stable fuel trim and absence of misfires, logging any diagnostic trouble codes and clearing them after successful operation. Compression test procedure and interpretation A proper compression test evaluates the cylinder sealing capability and ring condition without the interference of timing or fuel delivery systems. Begin with a fully charged battery, a cold engine, and a fully closed throttle plate to isolate the cylinders. Disable the ignition and remove the spark plugs to connect a calibrated compression gauge in each cylinder while cranking with the starter motor. Record the peak compression for each cylinder and compare against the manufacturer’s specified range, noting any significant variance that could indicate valve leakage, worn rings, or a blown head gasket. If compression is low, perform a wet test by adding a small amount of engine oil into the cylinder and retesting; a marked improvement typically points to ring or bore wear, whereas minimal change suggests valve or head gasket issues. Interpreting the results requires correlating compression values with engine temperature, ambient conditions, and recent maintenance history. A consistent low compression across all cylinders often indicates a broad issue such as a head gasket failure or a timing component problem, whereas a single low cylinder points to localized wear or valve seating problems. Use a bore scope if available to inspect valve seats, combustion chamber cleanliness, and potential carbon buildup that could affect sealing. After completing testing, reseal all access points, reinstall spark plugs with proper torque, and clear any diagnostic trouble codes through the service procedure. Ensure the cooling and fuel systems are also rechecked for leaks or abnormal operation, as cross-system factors can influence perceived compression symptoms.Chassis and Hydraulics Maintenance
