You might also hear a clicking or grinding noise coming from the tensioner. Squealing and chirping usually happen when the tensioner wears out. If you hear a constant ticking sound, the belt most likely came loose and may need to be replaced as well..
Thereof, what are the signs of a bad timing belt?
Symptoms of a Bad Timing Belt
- #1 – Rough Idling of the Engine. There are teeth on timing belts which grip gears as they're rotating various engine parts and components.
- #2 – Misfire of the Engine.
- #3 – Smoke from the Engine.
- #4 – Oil Pressure Decline.
- #5 – Pistons or Valves That Are Broken.
Additionally, what does a loose timing belt sound like? When the timing belt gets loose, it will start to knock around and hit the timing cover and the other parts inside of it. If it does not exactly sound like knocking, then it might be more of a slapping sound instead.
Keeping this in consideration, what does a bad timing chain sound like?
Unusual sounds are also a common warning sign of a problem inside your motor. However, when the timing chain is loose, it may cause a vibration inside the motor and that will produce a rattling noise as the engine idles. Anytime you hear a rattle it means something is loose and needs to be fixed before it breaks.
What happens if your timing belt breaks while driving?
If a timing belt breaks, the engine will no longer work. If a timing belt breaks while driving in an interference engine, the camshaft stops turning leaving some of the engine valves in the open position. The heavier crankshaft will continue rotating by inertia, moving pistons up and down.

It may fail while driving and cause the engine to stall or you may be suddenly surprised when your vehicle just won't start. There are rarely any warning signs that the timing belt is weak.Can low oil cause timing belt to break?
If the tensioner has no oil pressure, the belt will become loose and possibly disengage from the pulleys and/or break. Additionally, if the camshafts don't have enough to operate properly, they will lock up, which can cause the timing belt to break.What happens when engine timing is off?

Look for the check engine light to activate on the dashboard. When the timing belt becomes loose, it can cause the engine to stop working efficiently. The loose belt causes the engine's valves to fall out of sync, opening and closing at different times. A bad tensioner is often the cause of this kind of issue.What causes a timing belt to jump?
There are several reasons, The tensioner is failing and not holding adequate tension on the belt. The belt is excessively worn and the teeth on the belt are coming off. Debris either external or bits of belt getting between the belt and a pulley.Do timing belts squeal?
Failing Water Pump Pulley: The most common cause of squealing or squeaking from the timing belt cover is the water pump pulley.

When the water pump bearings go out it will cause a squeaking, ticking or grinding noise while the engine is running. This is because the shaft bearings are trying to lock up within the pump housing. This bearing failure is due to the pressure being applied by the serpentine belt or the timing belt.
