Expert Engine Diagnostics
You need your fleet to be performing at its best. To prevent breakdowns, it is critical to identify potential engine issues through engine diagnostics. At Schroeder Truck Repair, we not only perform comprehensive engine diagnostics, but we are also equipped to handle any necessary maintenance or repairs thereafter.
Engine Diagnostics
- OBD II (On-Board Diagnostics) Scanning: Our mechanics utilize an OBD II scanner to retrieve common diagnostic trouble codes (DTCs) from the engine control module (ECM). Then we interpret and address any codes related to the engine system.
- Fuel System Analysis: First we check fuel lines and fuel injectors for proper function and fuel spray pattern. Then we inspect fuel pressure to ensure it meets specifications. Last, we evaluate the condition of your truck’s fuel filter and replace as needed.
- Ignition System Testing: We’ll test your fleet’s ignition coils, spark plugs, and spark plug wires for wear and proper function. We also check ignition timing and adjust it if necessary. We inspect the distributor (if applicable) for wear and proper alignment.
- Air Intake System Inspection: Schroeder Truck Repair technicians inspect the air filter in your truck and replace it if it’s dirty. We also check the mass airflow sensor (MAF) for proper readings and ensure that the throttle body is clean and functioning correctly.
- Exhaust System Evaluation: Exhaust system diagnostics include an inspection of the exhaust system for leaks, damage, or excessive rust. We also monitor oxygen sensor readings to ensure proper fuel-air mixture.
- Compression Testing: First we conduct a compression test to assess the health of the engine’s cylinders. Then we identify and correct any variations in compression between cylinders.
- Cooling System Check: Schroeder mechanics check your fleet’s radiators, hoses, and water pumps for leaks and damage. We verify the functionality of the thermostat in each truck and also check coolant levels and quality.
- Oil Analysis: We start by analyzing and assessing the condition of your engine oil. We check for contaminants, such as metal particles, and monitor oil viscosity, replacing oil as needed.
- Engine Timing and Belt Inspection: Our technicians inspect your truck’s timing belt or timing chain for wear. We check and adjust the engine timing as needed.
- Turbocharger/Supercharger Examination: If your truck is equipped with a turbocharger or supercharger, our mechanics will inspect it for proper function, alerting you to signs of wear or damage.
- Emission System Testing: Vehicle emissions tests ensure compliance with emission levels standards and allow us to monitor the functionality of components like the EGR (Exhaust Gas Recirculation) valve.
- Crankcase Ventilation System Check: We inspect the PCV (Positive Crankcase Ventilation) system in your truck for proper ventilation and replace PCV valves as needed.
- Engine Mounts and Vibration Analysis: First we examine engine mounts for wear and damage. Then we conduct a vibration analysis to identify any irregularities that may indicate engine problems.
Regular engine diagnostics, conducted as part of routine maintenance, help detect issues early, optimize fuel efficiency, and extend the overall lifespan of fleet trucks. Incorporating these diagnostics into a preventive maintenance schedule is crucial for the reliability and longevity of the fleet.
