Engine D24
Symptoms:
- Hard starting or failure to start
- Rough idling and loss of power
- Excessive smoke from the exhaust (black or white)
- Overheating or coolant leaks
- Unusual noises from the injection pump or engine
Diagnosis:
- Check for clogged fuel filters or air filters restricting flow
- Inspect glow plugs and wiring for proper operation
- Test fuel injection pump timing and delivery pressure
- Examine coolant system for leaks, thermostat function, and radiator condition
- Look for signs of injector leaks or worn injectors causing smoke
- Listen for abnormal noises indicating injection pump wear or timing gear issues
Fixes:
- Replace fuel and air filters regularly to maintain flow and prevent contamination
- Repair or replace faulty glow plugs to improve cold starts
- Adjust or rebuild the fuel injection pump to restore correct timing and pressure
- Flush and refill coolant system; replace faulty thermostat or radiator components
- Clean or replace injectors to eliminate smoke and improve combustion
- Service or replace injection pump components if worn or noisy
Prevention:
- Follow strict maintenance schedules for fuel and air filter changes
- Use quality diesel fuel and additives to reduce injector deposits
- Regularly check and maintain the cooling system to avoid overheating
- Monitor engine performance and address symptoms early to prevent major damage
- Keep injection pump and timing components serviced according to manufacturer guidelines
By adhering to these diagnostic steps and maintenance practices, owners of Volvo 740 and 940 Diesel models with the D24 engine can ensure reliable operation and longevity.
