What Causes the Car Belt to Squeak in Cold Weather?

[MacBraxton]

The reasons for the car belt squeaking in cold weather are: 1. The belt tightens due to low temperature before the vehicle starts, causing noise; 2. The belt is severely aged and nearing the end of its service life; 3. The belt is too loose or too tight. The functions of the belt are: 1. Ensuring accurate intake and exhaust timing; 2. Synchronizing engine ignition and cylinder movement; 3. Ensuring smooth power output from the engine. The method for replacing the car belt is: 1. Lift the vehicle and remove the right front wheel fender liner; 2. Remove the alternator belt and the alternator belt tensioner; 3. Loosen the crankshaft pulley bolt; 4. Open the engine hood and remove the coolant reservoir; 5. Remove the engine mounting bracket and the protective cover on the belt; 6. Unscrew the alternator mounting bolt and remove the alternator; 7. Remove the cylinder block mounting bracket and take off the crankshaft pulley; 8. Rotate the crankshaft to the top dead center position of the cylinder and mark it; 9. Remove the belt and the tensioner.
