How Does a Belt Tensioner Work?
The timing belt is at the heart of any engine operation, as it effectively connects several crucial components such as the water pump, air conditioner, power steering pump and alternator and provides the drive to enable each of those components to spin properly.
The main source of energy is the engine’s crankshaft, which is being turned at high speed by the pistons as the mixture 'explodes' in sequence above them. The belt also connects the crankshaft to the camshaft, to make sure that those explosions happen at just the right time. The timing belt makes sure that each of the crucial components works in synchronicity with each other and the tensioner provides just the right amount of that tension to make this happen. It’s a relatively simple set up comprising a pulley, spring and an adjustment device, but it’s crucial to ensure that the adjustment is made very carefully in all cases.
