Why do timing belts break?
The tensioner that keeps the belt taut is pressurized by the engine oil. If the tensioner has no oil pressure, the belt will become loose and possibly disengage from the pulleys and/or break. If the camshafts don’t have enough oil pressure to operate properly, they will also lock up, causing the timing belt to break.
How much does it cost to fix a broken timing belt?
If your timing belt is in need of replacement, you can expect that service to cost anywhere from $300 up to $500.
