What Is Trend Monitoring:

Trend monitoring is a means by which aero engines are managed. The intention is to reduce the incidence of breakdowns or the need to have expensive repairs performed away from convenient maintenance locations. The same method can be used to manage car engines and provide the same advantages. By regular checking of all the fluid levels and monitoring of the fuel burn rate, advanced warning of pending trouble is provided.


Early Warnings:

Forewarned is forearmed. An unexpectedly lowered fluid level can be a warning of a pending breakdown. Expensive towing costs and missed appointments can then be avoided.

Monitoring Trends:

A simple example is a loose Oil Filter which results in a slowly lowering Oil Level. The resultant under car oil stream can also result in misleading diagnoses, like a failed Rear Oil Seal. Stemming a manifold leak early may offset the need to replace the associated gasket. A change in plug colour could mean a problem with a valve lifter, failing plug lead, an injector problem or other problem. A leaky radiator cap can be a direct cause of coolant loss. If a Trimatic level is dropping, the pan gasket may have shrunk and the pan bolts need retorquing. Slipping on downshift can be caused by low oil level.

Distance:

Over a long distance, a small leak may result in a catastrophic engine, gearbox, transmission, brake or differential failure. A fuel leak may result in a fire.

Brakes:

Inspect the wheels for signs of brake fluid loss from wheel cylinders or disc brake cylinders.

Rear Axle:

Don't forget to inspect the differential for external signs of oil loss such as an oil spot on the garage floor, oil loss from the rear wheels or oil on the rear axle housing or diff centre.
