What sound does a faulty tensioner pulley make on the new Santana?
1 Answers
New Santana tensioner pulley noise is a continuous sound that becomes sharper as engine speed increases, requiring inspection at a repair shop. Below are the causes of tensioner pulley noise: Bearing failure: Quality issues with the bearing itself, incorrect model selection, overly tight installation, improper tolerance matching with the bearing, or lack of lubrication can all cause abnormal noise. Incorrect belt tension: Improper belt tension leads to noise during operation. It is recommended to check whether the belt is aged or improperly tensioned, and adjust or replace it if necessary. Misjudgment of noise from other components: Since the entire belt system is connected to the water pump, power steering pump, and alternator, misjudgment may occur.
