Symptoms of a loose car engine belt: unstable engine operation, weak acceleration, high fuel consumption, black smoke during acceleration, and elevated water temperature. More information about car engine belts is as follows: 1. Car engine belts are generally divided into two types: one is the timing belt of the engine's valve train, and the other is the drive belt for external engine equipment, such as the generator, air conditioning compressor, water pump, power steering pump, etc. 2. When the tension of the timing belt in the engine's valve train is insufficient or the belt is aged and stretched, it will affect the normal opening and closing of the engine's intake and exhaust valves. 3. A loose belt can also cause abnormal noises when accelerating due to the belt hitting the belt housing. In the most severe cases, timing belt skipping or even timing belt breakage may occur, leading to damage to the engine's valves.
