Which way does the belt deviate when one side is tight and the other side is loose?
2 Answers
The belt tends to deviate towards the tighter side when one side is tight and the other side is loose. Belt deviation in vehicles can significantly impact the operation of motor vehicles. The timing system of a vehicle is composed of belts, and any issues with it can affect both the intake and exhaust systems, potentially causing the vehicle to stop functioning. More related information is as follows: Belt replacement cycle: The timing belt of a motor vehicle should be replaced approximately every 100,000 kilometers. Since timing belts are made of rubber material, prolonged use can lead to aging. When noises are heard from the timing belt, it is necessary to promptly inspect or replace it to prevent engine operation issues. Replacing the timing belt: For replacing the timing belt of a motor vehicle, you can visit the brand's after-sales service department or a larger repair shop. It is crucial to replace or inspect the timing belt according to the specified schedule to ensure the vehicle's normal operation and avoid potential safety hazards.
I've been fixing cars for over 20 years, this situation is very common. When the belt is tight on one side and loose on the other, the car will definitely pull towards the tight side. Because the tight side pulls on the tire, increasing resistance, making that wheel rotate slower; while the loose side has less resistance, allowing the wheel to spin faster. The difference in rotation speed between the two sides naturally pulls the car towards the tighter side. Last month, I fixed an old Bora with exactly this issue - the owner complained the steering wheel kept pulling left at highway speeds. I immediately noticed the left belt was taut like a bowstring while the right side was sagging. After readjusting the tensioner, the pulling disappeared instantly. For routine checks, it's simple: just press on both sides of the belt with your hand. If you feel uneven tension, be alert - don't wait until tire wear becomes severe to regret it.
