GENERAL MAINTENANCE INFORMATION - GAS ENGINES
Submitted by Fordace / 04-22-07



This is a generic maintenance schedule for all Ford, Lincoln and Mercury vehicles. There may be items listed that do not apply to all vehicles.




The Normal Schedule applies to operation of the vehicle under typical, everyday driving conditions. The maintenance frequency in this schedule typifies what the vast majority of vehicles will require. The listed services should be carried out at specified mileage intervals. There are, however, additional services required that only the noted vehicles require. If the vehicle is operated in one or more of the following special operating conditions, those additional services will be required. The special operating conditions are:
  • towing or carrying heavy loads.
  • extensive idling and/or driving at low speeds for long distances.
  • driving in dusty conditions.
  • off-road operation.
There are also exceptions to the Normal Operating Schedule which will require more frequent maintenance for some components. Those exceptions are:
  • natural gas and propane vehicles — fuel tank intervals.
  • normal vehicle axle — maintenance and lubrication.
  • police and taxi vehicles — maintenance and lubrication.
  • engine oil and yellow coolant — time and mileage-based interval.
Special Operating Condition Requirements
When towing a trailer or using a camper or car-top carrier:
  • Change engine oil and install a new oil filter, lube front lower control arm and steering linkage ball joints with zerk fittings (if equipped) every 4,800 km (3,000 miles) or 3 months.
  • Inspect brake system and check battery electrolyte level (Patrol cars) every 8,000 km (5,000 miles).
  • Install a new fuel filter every 24,000 km (15,000 miles).

  • Install new spark plugs and change transfer case fluid every 96,000 km (60,000 miles).
  • Install a new cabin air filter as required.
When operating in dusty conditions such as unpaved or dusty roads:
  • Change engine oil and install a new oil filter every 4,800 km (3,000 miles) or 3 months.
  • Install a new fuel filter every 24,000 km (15,000 miles).
  • Change automatic transmission fluid every 48,000 km (30,000 miles).

When operating in off-road conditions:
  • Change automatic transmission fluid every 48,000 km (30,000 miles).
  • Change transfer case fluid every 96,000 km (60,000 miles).
  • Install a new cabin air filter as required.
  • Inspect and lubricate U-joints.
  • Inspect and lubricate steering linkage ball joints with zerk fittings.
Checks and Services
Certain basic maintenance checks and inspections should be carried out at specified intervals. Any recognized adverse condition should be corrected as soon as possible.
