Engine & Mechanical Servicing

What does the engine do?

The engine is the heart of the vehicle, converting the energy stored in fuel into the power required to move the vehicle and run accessories such as heating, air conditioning and lights. Filters for oil, fuel, and the air required for combustion must be replaced periodically in order to prolong engine life and maximise efficiency.

The heat and friction generated by the engine causes service items to eventually wear. Engine oil contains additives that protect the engine from wear and corrosion, and these additives become depleted over time. Spark plugs ignite the fuel and air mixture in a gasoline engine; the constant electrical arcing eventually causes the plugs to wear out. Accessory drive belts and timing belts constantly flex and become worn over time.

Steering Inspection

Steering Systems

Most steering systems use a rack and pinion. As the steering wheel is turned, the teeth on the pinion gear at the end of the steering shaft move the steering rack left or right. The steering linkages and tie rod ends then force the front wheels to change angle. A power steering pump pressurizes hydraulic fluid. When the steering wheel turns, a valve in the rack and pinion assembly opens, allowing pressurized fluid to help move the steering rack in the desired direction.

Common Automobile Suspension Issues

Common automobile suspension issues to make yourself aware.

How does the suspension system work?

Suspension system design varies between vehicles, but the basic function is to keep the tire in contact with the road at the correct angle while absorbing bumps and road imperfections. Commonly used components include: ball joints (which allow components to rotate and change angle), springs, shock absorbers or dampers (that limit the rebound of the springs), rubber bushings (that absorb shocks while allowing some movement), and sway bars with their linkages, (that limit the amount of vehicle roll during cornering).

Broken Timing Belt

Engine & Mechanical Inspection at UFC St. Louis

Timing Belts

A broken timing belt is almost always preventable, and preferable to replace as a maintenance item.

The Camshaft Timing Belt (or Cambelt) connects the crankshaft at the bottom of the engine with the camshafts at the top of the engine. The teeth on the belt and on the crankshaft and camshaft sprockets ensure that the valves open and close at exactly the right times. The intake valve opens to allow fuel and air into the cylinder, then closes as the mixture is compressed then ignited, then the exhaust valve opens to allow the waste gasses out. A broken timing belt is almost always preventable, and preferable to replace as a maintenance item.
