How to Deal with Slipping Car Belts?
2 Answers
Methods to handle slipping car belts: adjust and tighten if possible, otherwise replace directly. Slipping car belts are usually caused by belt looseness, so tightening should suffice. If the slipping is due to belt aging, you can adjust the tightness and apply some belt oil. If it still doesn't work, the belt must be replaced. After prolonged use, belts undergo millions of twists and torsional deformations, which can easily lead to severe wear. This is a normal occurrence. There are three common types of car belts: timing belt, alternator belt, and water pump belt.
I've experienced belt slippage several times, all caused by aging and loosened belts. If you hear a sharp squealing sound from the engine compartment, especially during cold starts or when the AC is on, it's most likely this issue. First, turn off the engine and check the belt's condition - look for obvious cracks or oil contamination on the surface. Wipe the pulley with a tissue as oil can easily cause belt slippage. The simplest fix is adjusting tension: locate the tensioner nut and try turning it half a turn with a wrench. If you don't have tools, any repair shop can handle this in minutes. Never delay fixing this - a broken belt can make steering heavy and is highly dangerous. I recommend getting genuine belts from authorized dealers - they cost around 100 yuan and last years, far better than roadside breakdowns.
