Engine TD 27T

Symptoms:
- Hard starting or failure to start
- Excessive smoke from exhaust (black or white)
- Loss of power or poor acceleration
- Rough idling or engine misfire
- Overheating or unusual engine noises

Diagnosis:
- Check fuel system for clogged filters or air in lines
- Inspect glow plugs and wiring for proper operation
- Examine turbocharger for shaft play or oil leaks
- Test compression to identify worn piston rings or valves
- Look for coolant leaks or radiator blockages causing overheating

Fixes:
- Replace fuel filters regularly and bleed air from fuel lines
- Service or replace faulty glow plugs to improve cold starts
- Repair or rebuild turbocharger if damaged or leaking
- Overhaul engine components if compression is low (rings, valves)
- Flush cooling system and repair leaks; replace thermostat if needed

Prevention:
- Use high-quality diesel fuel and change filters every 10,000 km
- Maintain regular oil changes with correct grade oil to protect turbo
- Avoid prolonged idling and allow turbo to cool down after heavy use
- Monitor coolant levels and condition to prevent overheating
- Conduct periodic engine tune-ups and inspections to catch issues early
