Preventive maintenance has the following meanings: The care and servicing by personnel for the purpose of maintaining equipment, and facilities in satisfactory operating condition by performing systematic inspections, leading to detection, and correction of incipient failures either before they occur or before they develop into major defects. Maintenance, including tests, measurements, adjustments, and parts replacement, performed specifically to prevent faults from occurring. The primary goal of maintenance is to avoid or mitigate the consequences of failure of equipment. This may be by preventing the failure before it actually occurs which Planned Maintenance and Condition Based Maintenance help to achieve. It is designed to preserve and restore equipment reliability by replacing worn components before they actually fail. Preventive maintenance activities include partial or complete overhauls at specified periods, oil changes, lubrication and so on. In addition, workers can record equipment deterioration so they know to replace or repair worn parts before they cause system failure. The ideal preventive maintenance program would prevent all equipment failure before it occurs.
Preventative maintenance is used in many ways, on our bodies (proper health care), our mouths (proper dental care), equipment, buildings, machinery which includes our vehicles. In health care, regular check-ups, vaccines, and different testing procedures are considered preventative maintenance. At the dentist regular x-rays, inspections, teeth cleanings & polishing, and sealants are considered preventative maintenance. On the outside of your home or building, cleaning siding, concrete, gutters, roof and keeping it sealed and painted is considered preventative maintenance. The list of examples can go on and on.
In our vehicles the fluids are designed to protect the systems that they run within. They are one of the main maintenance items on your vehicle is to keep clean, full, uncontaminated and at the proper protection level. Preventative maintenance would be having the vehicle inspected regularly, and having the fluids changed regularly before they get dirty, changing them due to age and mileage. Preventative maintenance would be repairing the cause of any fluids seeping, before they are leaking and causing a low level issue. Preventative maintenance would be checking the fluids regularly for contamination that would prevent them from properly lubricating, cooling and conditioning the system in the vehicle it is designed to protect.
There are other systems within our vehicles that need preventative maintenance:
Tires: Rotated regularly and tire pressure checked and kept filled at spec.
Wheel Alignment: Checking at least yearly for proper wheel alignment and performed if needed.
Spark Plug & Wires Replacement: Following manufacturers specification for replacement of these items.
PCV Valve, Fuel, Air and Cabin Air Filter: Have them inspected and replaced at least once a year.
Throttle Body & Fuel Injectors: Have them inspected and cleaned at least every 2 years.
Belts, Hoses, Idler Pulleys and Tensioners: Regularly inspected and replaced as they start to deteriorate or every 60,000 miles (timing belts should be replaced as recommended by manufacturer by age or mileage whichever comes first.)
Brakes & Clutches: Regularly inspect for leaks, operation and friction material and drum and rotor trueness and thickness.
Suspension: Regularly inspect for looseness or leaks and lube all points available.
Preventative maintenance is really the key for safety, reliability, and the longevity of your vehicle. Studies also show preventative maintenance when performed properly also costs about 50% less than just performing repairs when your vehicle breaks. So we recommend to start the New Year with the resolution to perform Preventative Maintenance on your vehicles!
