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
Visual Inspection of Hoses
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:
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:
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:
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:
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.
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 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 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.
Radiator & Coolant Hoses
Radiator and coolant hoses are vital to keep your engine from overheating. With time and use, hoses become brittle and weak. Don’t wait for a failed radiator or coolant hose to leave you stranded.
Coolant System Components:
TIMING BELTS…. WHAT ARE THEY?
Piston engines can generally be divided into two groups-Interference AND non-interference engines.
If a timing belt breaks on a non-Interference engine the engine will ‘free-wheel’ and the piston will not contact the valves.
On the other hand, interference engines will not ‘free-wheel”. Severe valve train and piston damage can result if the timing belt breaks while the engine is running.
TIMING BELT REPLACEMENT GUIDE
Most manufactures have recommended replacement Intervals for replacing timing belts. A typical service Interval in between 50,000 and 60,000 miles. It is important to replace timing belts at recommended Intervals even if the vehicle has a non-interference engine. Proper maintenance prevents expensive tow bills and possible accidents due to loss of engine power while traveling at highway speeds.
