Your engine depends on both the timing belt and the serpentine belt to keep everything running properly, but they serve very different functions. The timing belt synchronizes the movement of the crankshaft and camshaft, ensuring precise engine timing, while the serpentine belt drives multiple accessories like the alternator, power steering pump, and air conditioning compressor. Knowing how these belts work and when to replace them can help you avoid unexpected breakdowns and expensive repairs. What Is a Timing Belt The timing belt controls the precise movement of your engine’s camshaft and crankshaft, ensuring that the intake and exhaust valves open and close at the right time. This synchronization is critical for efficient combustion and engine performance. If the timing belt slips or breaks, it can cause serious engine damage, especially in interference engines where pistons and valves can collide. Unlike a serpentine belt, the timing belt is located inside ... read more

Car batteries rely on a chemical reaction to generate power, and when the temperature drops, that reaction slows down. This reduces the amount of power available to turn over the engine. Thicker engine oil is another problem in freezing temperatures. As the oil gets colder, it becomes more viscous, making it harder for the engine to turn over. If your oil is too thick for the season, your en ... read more
