Whining noise after timing belt change

#1

we just had our timing belt changed today as well as the waterpump and fanbelts. It has a loud whining noise now and I don’t know if it is even safe to drive back to the mechanic


#2

Call the mechanic. Tell him your concerns. Let him tell you if he thinks it’s OK to drive back to the shop. Get a commitment from him to be responsible for any damage that results from his advice.


#3

It is 95% likely related. It could be as simple as improperly tightened fan belt or possibly a failing tensioner.

Way more important than changing a water pump if not failed is the tensioner.


#4

If the whining did not exist before then it’s likely caused by someone getting the belt too tight.
