Where is the tensioner on a camshaft timing belt?
The tensioner is a roller which bears on the outside face of the belt. It has two adjustment bolts, one of them fitted over a slot. Slacken both bolts just enough to let you slide the tensioner. Move the tensioner as necessary to tighten or loosen the belt.
Why do you need a belt tensioner in your car?
The belt tensioner in your car is an important component. It maintains the correct tension on the drive belts. This helps facilitate the transmission of power to the different accessories of your car.
What does a loose belt tensioner sound like?
If the drive belt noise resembles a squeal or a squeak, it is possible that the belt tensioner is loose. This is especially the case when starting the engine first thing in the morning. Since the tensioner is not able to maintain the correct tension on the belts, it produces a squealing or squeaking sound.
How is the belt tension on a Leyland engine measured?
On Leyland ‘O’ series engines, the belt tension is measured with a spring balance and adjusted manually. The belt tensioner has no automatic spring. To measure the tension, use a spring balance with its hook bent to an L shape to fit flat against the belt. (If necessary, use a separate L hook.)
Is it necessary to replace the tensioner with the timing belt?
If a new belt is over-tightened, it could fail prematurely, or even break. When that happens, the broken timing belt can also cause neighboring components to fail. Additionally, the timing belt’s teeth can develop stress cracks, or even detach. If the belt looks worn or damaged, it needs to be replaced.
