If your old belt was glazed and slipping, then yes. The new belt does not slip therefore everything is turning and generating at full capacity, hence the improvement you see. Not really. All of your accessories power steering, air-conditioning, etc.
As you can see, driving without a serpentine belt is not an option, at least not for very long. Estimate does not include taxes and fees. When would you like to drop off your car? Effect of Serpentine Belts on Transmission. As a result, if the serpentine belt is worn out or breaks, it results in engine overheating and losing the powered steering and charging system.
Once the belt starts to wear thin or breaks, it will need replacing , if those parts are going to work as they should. The serpentine belt and the timing belt are all important parts of an engine. A serpentine belt does more work than a timing belt. Timing belts synchronize the movement of the crankshaft and the camshaft while the serpentine belt transmits mechanical power which drives the air conditioner, water pump, alternator, etc. The most common symptom of a bad or failing drive belt tensioner is noise from the belts or tensioner.
If the tensioner is loose the belts may squeak or squeal, especially when the engine is first started. Idler pulleys are engine pulleys that are responsible for guiding and tensioning the engine drive belts.
The engine drive belts are routed in a specific manner around the various engine accessories, such as the alternator, water pump, power steering pump, and AC compressor.
Most cars have one or two drive belts. It is also called a serpentine belt when there is only one drive belt in a car. Whether it is a drive or serpentine belt , it is a part of the accessories that drive a car's engine. If your serpentine belt wears out, becomes damaged or contaminated, or breaks, engine accessories will not be able to spin at the proper speed, leading to decreased power to the electrical system. This can lead to a sudden lost of power assist for the steering system, leading to the steering wheel all-of-a-sudden becoming very hard to turn.
A broken serpentine belt may stop the water pump from circulating coolant through the cooling system, causing the engine can overheat. A broken serpentine belt will have numerous negative effects on your engine and can potentially be dangerous. There are many indicators that your serpentine belt may need to be replaced.
Deep cracking in the ribs and spine of the serpentine belt is a common indicator your belt is due to be replaced. A noisy belt is also indicative of a problem. Your serpentine belt can also become contaminated with oil or coolant due to other issues with the vehicle. These contaminants will reduce the life of the belt and contribute to irregular noises. An aged belt may become shiny or glazed in appearance. It may also begin to harden and lose some of its flexibility. An aged belt made of EPDM rubber may also show excessive wear in the ribs and valleys of the belt which can lead to slippage.
Belt noises can be diagnosed with a spray bottle of water. With the engine running and the sound audible, lightly mist the grooved side of the belt with water. If the noise disappears or lessens, but then shortly returns, the problem is probably a misaligned pulley. If the noise immediately increases after the belt is misted, the belt is slipping.
Another diagnostic trick is reversing the belt: take it off and put it back on so that it travels in what would have been its backward direction as originally installed. If the noise goes away or gets much softer, the problem is a misaligned pulley.
If reversing the belt does not temporarily eliminate the noise, the problem is something other than misaligned pulleys.
Next, examine the belt itself. Glazing at the edges of a serpentine belt, or on its ridges or in the grooves, results from the belt slipping. It indicates that friction between the belt and the accessory drive pulley s created by slipping has overheated the belt. Fraying at the edge of a belt indicates pulley misalignment. The edge frays because it is scraping on the top edge of an accessory drive pulley side as the belt feeds into it. Fluid contamination attacks the rubber surface of the belt.
All of the automotive fluids that can leak onto a belt—oil, power steering fluid, coolant—are petroleum based and will attack rubber. Once on the belt, any of these fluids will be distributed over the pulley groove surfaces, making them slippery and attracting dirt. Serpentine belts stretch with age and use, but the tensioner is spring-loaded to keep the belt tight on the pulleys. If a belt starts slipping, the tensioner should always be checked to see if it is functioning properly.
With the belt off, visually inspect the tensioner for any cracks or signs of metal-to-metal contact between the tensioner arm and the spring case. Then spin the tensioner pulley manually.
