Most vehicle break downs today are related to belts, hoses and cooling system problems.  Today’s vehicles run hotter than ever before and have more packed into a tighter area than ever before.  Belts and hoses are prone to cracking and deterioration from the elements.  These items often can crack, leak, or fray from constant exposure to heat, vibration, and other harmful chemicals.  If not properly maintained, any one of these could spell disaster for your engine performance. 

 

Here are some of our recommendations to ensure belt and hose quality:

 

Visual Inspection of Belts

 ● Search for clear indications of damage (cracking, glazing, softening, or peeling)

 ● Test for correct tension

 ● Test for correct alignment

 ● Record belt condition for future reference

 

Visual Inspection of Hoses

 ● Search for leaks, cracks, hardening, or softening.

 ● Test cooling system for leaks using state-of-the-art pressure technology

 ● Record hose condition for future reference

 

Get your vehicle's belts and hoses inspected on a regular basis because damaged pieces can seriously harm your vehicle. Research shows that while most people get regular oil changes, they neglect the condition of their belts and hoses. A leaking hose or a cracked belt will cause you more trouble than an overdue oil change ever will.

 

Below are brief descriptions of some of the different belts and hoses we inspect:

 

Drive Belts:

The engine drives some of your vehicle's accessories. Instead of being supplied by electric power, these accessories rely on a series of pulleys and belts to operate. Some of these accessories include:

 

•  Power steering pump

•  Alternator

•  Air conditioning compressor

•  Radiator cooling fan

•  Water pump

 

​

Some vehicles require a single serpentine belt to power these accessories (as opposed to several individual belts).

​

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.

Hoses:

If you think of hoses as your vehicle's circulatory system, then you'll have an appropriate representation of their importance. Hoses are composed of two rubber layers with fabric in between. Types of hoses vary on make and model, but typically include:

 

 ● Fuel hose (sends gasoline from the gas tank to the engine)

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

 ● Power steering hose (connects power steering pump to steering equipment)

 

Serpentine Belt

You know that long belt that snakes around the front of your engine? It’s called the serpentine belt. The serpentine belt is driven by the engine as it turns. It powers your alternator, air conditioning compressor, and power steering pump. On some vehicles it also runs the water pump, radiator fan, and power brakes. Sounds like a lot of important stuff doesn’t it?

​

If your serpentine belt were to break on one of our 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 owner’s manual for when it’s recommended that you replace your serpentine belt – or just ask our service advisor for assistance. We can inspect the belt as well to see if it’s in trouble.

You may have been told by a service adviser 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 doesn’t 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 (squeal) or be misaligned, putting undue stress on the accessories it runs.

Now you can imagine it’s important for the belt to be tight, so there’s 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.
