Your radiator holds the coolant that carries heat away from the engine. A car radiator leak lets that coolant escape slowly. Less coolant means less cooling, and the engine temperature starts to climb. In Dubai, that climb can happen fast. A 45°C afternoon and slow traffic put the car cooling system under heavy load.

Old engine oil breaks down with heat and distance. It gets thinner, collects dirt and fuel, and stops forming a protective film between metal parts. Friction then rises inside the engine. Sludge builds up in the oil passages and around the oil pump pickup. The engine runs hotter, uses more fuel, and loses power. If … Read more
Your car has two air filters, and each does a different job. The engine air filter cleans the air your engine burns with fuel. When it clogs, the car feels slow when you press the pedal. The cabin air filter cleans the air coming out of your AC vents. When it clogs, airflow drops and … Read more

Your car has a shock absorber near each wheel. Its job is simple. It stops the springs from bouncing after the car hits a bump.
