Belts & Hoses


Exposure to heat, vibration and contamination makes belts and hoses wear out faster than any other components in your car. That's why regular inspections are so important. Here are the belt and hose types in your car, along with their applications.

Bring your car into Hoffman Auto Repair in Canal Winchester Ohio for a cooling system check, Inspection of radiator hoses and fluids along with timing belt, serpentine belt are just a few of the 51-point inspections that our auto service garage performs.Accessory Drive Belts

While some accessories in your car are electrically powered by the charging system, others use the engine itself as their power source. The power for these accessories is delivered by a system of pulleys and belts. Examples of these accessories are:

  • Alternator

  • Water Pump for engine cooling

  • Power Steering Pump

  • Air Conditioning Compressor

  • Radiator Cooling Fan

  • Many late model cars use a single serpentine belt in place of individual belts to drive these accessories.


The hoses that convey your car's fluids are made of two rubber layers with a layer of fabric in between. Typical hoses include:

  • Radiator and Heater Hoses - These hoses convey coolant to the engine and heater core.

  • Fuel Hose - As the name implies, this hose transports gasoline from the tank to the engine.

  • Power Steering Hose - It connects the power steering pump to the steering gear.

Serpentine Belt


You know that long belt that snakes around the front of your engine? Itís called the serpentine belt. The serpentine belt is driven by the engine as it turns. It powers your alternatorair conditioning compressor, and power steering pump. On some vehicles it also runs the water pumpradiator fan, and power brakes. Sounds like a lot of important stuff doesnít it?

If your serpentine belt were to break on one of our Central Ohio roads, your battery would die in a few miles. If it runs your fan or water pump, your engine could overheat. And steering and braking could be more difficult. Obviously, the best thing is to replace your serpentine belt before it breaks.

Check your ownerís manual for when itís recommended that you replace your serpentine belt Ė or just ask a service advisor at Hoffman Auto Repair. We can inspect the belt as well to see if itís in trouble.

You may have been told by a service advisor to look for cracks in your belt to see if it needs to be replaced. Of course, cracks are still a concern, but modern belt material doesnít crack as often as old belts did. What we look for these days is the thickness of the belt. There are tools available that measures the depth of the grooves in the belt to see if it needs replacing.

A worn belt can slip or be misaligned, putting undue stress on the accessories it runs.

Now you can imagine itís important for the belt to be tight, so thereís a tensioner pulley on your engine that puts pressure on the belt to keep it at the right tension. The spring on the tensioner wears out over time so we recommend replacing the tensioner pulley at the same time as the serpentine belt.

Replacing your serpentine belt on schedule, or when an inspection warrants it, will keep you from an unexpected breakdown.
