Fuel Filter The fuel filter removes dust particles and water in the fuel, preventing them from entering the engine. If you continue to use a clogged fuel filter, it will impair the optimum fuel supply to the engine, causing poor starting and sluggish acceleration. New Filter: Deteriorated Filter:

Brake Fluid Brake fluid transmits a brake pedal force to the brake pads/shoes when the brake is applied. Brake fluid gradually deteriorates because of moisture in the air entering it through the brake hoses, and also because of oxidation due to the heat produced by friction. As a result, the brake fluid may boil. If deteriorated brake fluid is continuously used under severe conditions, it may lead to the dangerous "vapor lock" phenomenon where the fluid boils and can not transmit a brake pedal force to the brake pads/shoes, meaning no brake! New Brake Fluid: Deteriorated Brake Fluid:

Spark Plug The spark plug transmits an extremely high voltage across the electrodes to produce sparks, which ignite the air-fuel mixture in the engine cylinder. The spark plug electrodes gradually erode over time and thus the gap between them widens, making spark generation difficult. If an eroded spark plug is continuously used, poor engine performance and worsened fuel economy may result. New Spark Plug: Deteriorated Spark Plug:

Engine Oil & Engine Oil Filter The engine oil has a variety of important functions - lubricating, cleaning and cooling, for example - to ensure that the engine continues to work smoothly and efficiently. The oil gradually deteriorates with use because of dust and metal particles as well as oxidation. If you continue to use deteriorated oil, it will cause poor engine performance, overheating, worsened fuel economy, or even engine seizure, in the worst scenario. The oil filter removes impurities from the engine oil, keeping it clean. If you continue to use a clogged oil filter, it will cause the engine oil to become contaminated. This will lead to poor engine performance, overheating, or worsened fuel economy. New Engine Oil & Engine Oil Filter: Deteriorated Engine Oil & Engine Oil Filter:

Timing Belt The timing belt transmits crankshaft power to the camshaft, thus enabling the intake and exhaust valves to open and close in accordance with the specified valve timing. If you continue to use a worn timing belt, it will finally jump the sprocket teeth and, in the worst case, break. This will decrease engine performance and may seriously damage the valves and pistons. New Timing Belt: Deteriorated Timing Belt:

Air Cleaner Filter The air cleaner filter traps dust and dirt particles in the air, preventing them from entering the engine cylinders. If you continue to use a clogged air cleaner filter, it will cause the air flow to be restricted, thus leading to decreased engine performance and worsened fuel economy. New Air Cleaner Filter: Deteriorated Air Cleaner Filter:

Engine Coolant The engine coolant mixed with anti-freeze cools the engine, prevents the engine from freezing, and prevents the engine cooling circuit from corroding. The engine coolant deteriorates due to heat and chemical changes over time. If you continue to use deteriorated engine coolant, it will lead to engine overheating, and damage to engine cooling components. New Engine Coolant: Deteriorated Engine Coolant:

Muffler The muffler reduces exhaust noise by lowering the temperature and pressure of the exhaust gas. The muffler gradually corrodes on its inside because of the moisture and sulfides in the exhaust gas. Its outside surface will also corrode due to the moisture in the air. If you continue to use a corroded muffler, it will eventually perforate, leading to a loud exhaust noise. New Muffler: Deteriorated Muffler:

Driveshaft Boot The driveshaft boot prevents dirt and water from entering the joint of the driveshaft, which is packed with grease. The boot is made of rubber and gradually deteriorates with use. If the boot is damaged, dirt and water can enter the joint and the grease will leak. This may cause the joint to wear out, making abnormal noises or vibrations. New Driveshaft Boot: Deteriorated Driveshaft Boot:

Tyres The tires ensure a safe ride, allow you to stop and turn, and also give a comfortable ride by absorbing irregularities in the road surface. The tires become worn because of friction with the road surface and deteriorate due to ambient temperature changes. If you continue to use worn out tires, it will lead to erratic vehicle movements when cornering or braking, reduced braking performance, erratic skidding on wet road surfaces, and poor riding comfort. New Tyre: Deteriorated Tyre:

Wiper Blade The windshield wipers wipe away rain and snow as well as dirt on the windshield and/or the rear window to keep them clean. The wiper blade is made of rubber and deteriorates due to the temperature changes and friction with the glass surface. If you continue to use a deteriorated wiper blade, the wiper will have a jerky movement and will produce a squeaking sound, and water or a dirty film will remain on the glass, leading to poor visibility. New Wiper Blade: Deteriorated Wiper Blade:

Clutch Disc The clutch disc engages or disengages the driving power transmission from the engine to the transmission. Over time, it becomes worn due to friction. If a worn clutch disc is continuously used it will slip, leading to poor driving performance and fuel economy, and eventually it may become impossible to start the vehicle. Furthermore, a worn clutch disc can damage the clutch cover and flywheel, leading to expensive repairs. New Clutch Disc: Deteriorated Clutch Disc:

Drive Belts (Fan Belt, Alternator Belt, Power Steering Belt, Air Conditioner Belt) The belts deliver crankshaft power to the water pump, cooling fan, alternator, power steering oil pump, and air conditioner compressor. If you continue to use worn belts, they will finally break, leading to engine overheating, a discharged battery, or inoperative power steering/air conditioner. New Drive Belt: Deteriorated Drive Belt:

Brake Disc / Brake Drum The brake disc/brake drum stops the vehicle due to the braking force produced by friction with the brake pads/shoes. They can become worn because of friction. If you continue to use a worn out brake disc/drum, braking performance will be reduced, the brake pedal may vibrate/judder, and the steering may even vibrate when braking. New Brake Disc: Deteriorated Brake Disc: New Brake Drum: Deteriorated Brake Drum:

Brake Pads / Brake Shoes Friction between the brake pads and brake disc (in disc brake systems) produces the braking force, and friction between the brake shoes and brake drum (in drum brake systems) has the same effect. The pads and shoes become worn as a result of frequent brake applications. If you continue to use completely worn out brake pads/shoes, braking performance will be lost, a squeaking noise will occur, and the brake disc/drum surface may become damaged. New Brake Pad: Deteriorated Brake Pad: New Brake Shoe: Deteriorated Brake Shoe:
