Can a loose belt cause knocking noise?
If the tensioner is not keeping the belt tight, the belt can come loose and hit various parts inside of the timing cover, including the cover itself. This can cause a slapping or knocking noise.
Where does the knocking come from in an engine?
Another possible source of engine knocking isn’t actually coming from the engine itself at all. It could be coming from the accessory belt. As the engine runs, it turns a belt that’s connected to various pulleys throughout the engine bay. This belt must be under the exact right amount of tension so that it turns smoothly and quietly.
What happens when a water pump pulley wears out?
When the water pump pulley wears out, the pulley will refuse to turn, which results in a water pump that doesn’t efficiently circulate water throughout the engine.
Can a bad knock sensor cause an engine to knock?
There’s even a knock sensor that’s designed to detect engine knock and tell the Engine Control Unit, so it can correct the problem automatically. This naturally means that a bad knock sensor can allow the engine to knock.
What are the signs of a bad water pump?
