What is the AC Belt all about? The AC belt connects the engine’s crankshaft to the air conditioner and without the AC belt, the air conditioner will not work. In some vehicles, the defrost function may be limited or even non-functioning if the AC belt is broken. The AC belt is not considered a major issue in that it won’t interfere with the vehicle’s ability to run; however, if the AC belt fails, the indoor temperatures may not be regulated properly. The AC belt is verified to be needing replacement The AC belt tensioner is loosened and the old belt is removed The new AC belt is installed The AC belt tensioner is adjusted to specifications The AC is checked for proper operation If you hear squealing when the air conditioner is turned on, or notice that the AC belt appears to be frayed, stretched, or worn, one of our expert mechanics can inspect the belt and replace it for you if necessary. An inspection will help eliminate causes of AC belt failure other than normal wear and tear.

Occasionally, a different broken part can interfere with the belt, causing failure. If the AC belt is broken, you’ll need to have it replaced if you want to have a working air conditioner. During the winter, the air conditioning unit helps to dehumidify the car during the defrost cycle, so repair may be essential during the winter months.what size ac unit for 500 sq ft What common symptoms indicate you may need to replace the AC Belt?how to install ac window unit in a wall Noise, such as squealing when the air conditioner is turned ontop ac units brands Visual inspection shows fraying, stretching, or weakening of the belt The vehicle’s air conditioner will not run without a properly functioning AC belt. While this isn’t a major issue, it can be rather uncomfortable in warmer climates.

The issue becomes more important in the winter, if weather necessitates use of the defrost setting on the heater.The AC belt is probably the most simple component of a vehicle's AC system, but still a very important one. The belt connects the AC compressor clutch to the engine crankshaft, which allows the compressor to be turned via the engine's power when activated. As with most automotive belts, the AC belt will either be a V-belt or a serpentine. A serpentine belt is flat and ribbed, and serves to connect several components, while a V-belt is narrower, shaped like a V, and connects only two components. Whatever the case, when the AC belt fails, or begins to fail, it will display symptoms that will alert the driver that the belt needs to be replaced. 1. Squealing noises when AC is on One of the most obvious signs that a belt needs to be replaced is that it will produce a loud squealing noise when the AC is turned on. In some cases, this may be attributed to a loose belt, or perhaps water or oil contamination.

However, in other cases this may be attributed to a severely worn belt that can no longer properly grip the pulleys. When the belt can no longer grip the pulleys properly, it will slip under the torque of the engine and squeal. Often times this squeal will be very high pitched and noticeable. This is probably the most obvious sign that the AC belt requires attention. 2. Cracks in the AC belt Another more visual symptom indicating that the AC belt needs to be replaced is that cracks will begin to form on the belt. The longer a belt has been in service, the more heat and wear it has been exposed to, which will eventually lead to dryness and cracking of the belt. An old belt will not grip properly and will actually be a lot more susceptible to breaking than a newer belt. If a belt is showing cracks then it should be replaced. 3. AC belt breaks Another obvious sign that the AC belt needs to be replaced is the belt snapping. Old belts will snap simply because they are weakened by age and service.

You can notice that a belt has snapped because the AC will not function when activated. A quick visual inspection of the belt should be able to identify if it has broken and needs to be replaced. 4. Inability to defrost windshield Another less common symptom indicating that the AC belt needs to be replaced is the windshield defroster not working properly. The defrosters in some vehicles are connected to the air conditioning system and will require the AC compressor to function for the defroster to work. If the belt snaps or is slipping, then neither the AC compressor nor the defroster will work. While the AC belt is a very simple component, it is very important to the operation of the AC system.
