Timing Belts connect the engine’s crankshaft with its camshaft gear. These two parts remain synchronised because of the rotation of the timing chain or belt. This in turn causes the car’s piston to pump up and down while the valve opens and shuts. These actions by the pump and valve lead to a combustion reaction. Though in most vehicles including GMC, belts are made up of composite material their work under high pressure and temperature causes them to go bad. A faulty timing chain can even damage your GMC’s engine. At Desire Auto our team can replace these chains at highly reasonable rates. So if you hear weird noises, oil leaks, and rough idling in your car, we advise you to visit Desire Auto for GMC’s Timing chain replacement.
