The cooling fan is a vital part of a car’s cooling system. It is sited just in front of the car’s radiator, and is electrically powered. A cooling fan in a car is activated by two means - either by the thermostat in the car’s cooling system, or by an electronic system that senses when the coolant is too hot and switched on the fan through an electrical relay switch. A cooling fan tends to be dormant unless the car is stationary or the temperature is excessively hot. In either scenario, not enough cooling air is being forced through the radiator, so the temperature goes up, and the fan is activated to increase the amount of cooling air being fed through the radiator element. However, listening out for the cooling fan can be a quick and easy way to tell if your car’s cooling system is working at peak efficiency or not. If you hear the fan being activated on a cool day, or if the fan is in operation after even a short run, there’s a good chance that the level of coolant in your car has dropped, or there’s a fault elsewhere, such as with the thermostat. It’s worth letting the car’s cooling system cool down so you can accurately check the level of fluid in the expansion tank - it should be between and H and L mark on the side of the tank. If the level of coolant is low, it’s worthwhile checking the state of the car’s rubber cooling pipes. These lead from the radiator to the expansion tank and from the car’s engine to the radiator. Vibrations caused when the car is moving can make the pipes wear if they happen to be rubbing against other components, and if there are any bulges in the pipes you should replace them straight away and bleed the system.

Clean air is essential to your vehicle running properly; your car’s engine air filter ensures that clean air reaches the engine. In the same way, your car’s ventilation system counts on the cabin air filter to keep a steady stream of clean air flowing. The cabin air filter keeps dust, dirt, pollen, bacteria and exhaust gases from entering the HVAC system of your car. It also prevents bugs, leaves and other debris from clogging up the system. Vital to clean air inside the car, the cabin air filter keeps the air inside the car fresh so you and your passengers can breathe easy – something you’ll appreciate all year long but especially during allergy season.

A front fog light is a type of automotive light that helps the driver see in front of the vehicle. It’s located below the headlight assembly and is designed to emit a wide beam of light that is shaped like a “bar,” with a sharp cutoff at the top to prevent it from reflecting off of the fog. Fog lamps are usually mounted reasonably low—typically about 12 to 30 inches above the road surface—and angled downward to illuminate the ground below the fog. Meanwhile, a rear fog light is designed to produce a red-colored light, much like your brake lights, to ensure that other drivers can see your car in low-visibility conditions. It is sometimes placed in the middle of the rear bumper cover or in place of one of the reverse lights.

Shock absorbers are an integral part of a vehicle’s suspension. A shock absorber is designed to absorb or dampen the compression and rebound of the springs and suspension. They control the unwanted and excess spring motion. Shock absorbers keep your tires in contact with the road at all times. When you hit any bump or dip in a road, your vehicle’s suspension and springs move so the tire can stay in contact with the road and absorb the energy. The shock absorbers dampen the movement of the springs by converting the spring’s kinetic energy into thermal (heat) energy. This thermal energy is then degenerated in hydraulic fluid. Shock absorbers are an oil-filled cylinder. When your vehicle’s suspension moves, a piston moves up and down through the oil-filled cylinder. The up-and-down movement of the piston forces small amounts of fluid through orifices (tiny holes) in the piston head. Since only a small amount of fluid is forced out, this slows down the suspension’s movement and dampens the compression and rebound of the springs. Shock absorbers are also velocity-sensitive. This means that the faster the springs are moving, the more resistance the shock absorber provides.
