Recommending Tensioners

Recommending Tensioners

If your customer is replacing a belt, they should consider replacing the tensioner as well.

If you look at the service manual for any 1980s vehicle, it will always recommend to adjust belt tension through a new oil change.

To do this, you either use the adjuster or add shims to a pulley. On some vehicles, you may have had to adjust up to three belts, but that all changed thanks to multi-rib belts and automatic tensioners.

The multi-rib belt increases the surface area a belt can use to transmit power to a pulley. The automatic tensioner keeps belt tension constant during changing engine speeds as well as loads. An automatic tensioner has a coil spring that applies the right amount of force against the belt to keep it tight.

The tensioner also provides a little give to absorb and cushion shock loads on the belt when the A/C compressor clutch cycles on or when the electric power steering activates. Also, inside the body of the tensioner are parts that dampen the movement of the arm and spring. Think of it as a shock absorber for the belt system.

We all know that vehicles run on gasoline. I think that we can also agree that gasoline is a very flammable fluid. Did you ever wonder how this fuel actually runs an engine and how it gets ignited to do so? Yes, it's very flammable, but it needs two other components to ignite. It must have oxygen and an ignition source. In our vehicles today, this source is the ignition system. Today, we are going to look into the system and its components. At the very root of the system is the actual part that supplies the spark to ignite. We all know that as the spark plug. But how does the spark plug convert electrical energy into a spark and how is it controlled? Early systems used a combination of points, condenser, and a distributor to get the spark to the fuel. In this system, the charge from the battery would build up in the coil until the points broke and grounded the coil, thus discharging the spark to the distributor and through the wires to the plug.
