Do you have to replace the ac compressor and surpentine belt when replace the harmonic balancer on a 2012 dodge journey

I took my car to the dodge dealership and was very unhappy. They said that I needed to change the plugs in my car and I had just had them do that. I told them that my car would vibrate when the ac was on but was worse when it was off and they went to looking for the problem and that's is when they came back with a list of things that I needed to have done. They said that I need to replace the harmonic balancer the ac compressor and the surpentine belt. I asked if we could do the balancer first and then the other two next and was informed no. I am just trying to get opinions since they have
Experienced mechanics share their insights in answering this question :
If all these components are the cause of the issue and need to be replaced, it makes more sense to replace them all at the same time to save on labor costs. There can be some overlap in labor. If for example, the a/c compressor has to be removed to replace the harmonic balancer, then there is not additional labor to install a new compressor when putting things back together. Evacuating and recharging the a/c system will be required whether replaced at the same time or separately. The serpentine belt has to be removed to replace either component so again, there should not be any additional labor to install the belt. A new belt is simply being installed instead of the old one being reinstalled. I cannot say that their diagnosis is correct or incorrect. However, I have never seen both the a/c compressor and harmonic balancer fail at the same time. Odds are either one or the other is the cause of your issue. If you are not comfortable with their answer, it wouldn’t hurt to get a second opinion. You can have the engine vibration looked at by another repair facility, or set an appointment with yourmechanic.com. One of our mobile technicians can come to your home or office to inspect the vehicle and give you an estimate for the necessary repairs.

The serpentine belt is one long, snaking, winding belt that keeps your alternator, power steering pump, air conditioning and—in some cases—your water pump running smoothly and effectively.
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.
They also help keep the belt in place. This is important since loose belts can cause systems like the power steering, cooling system, and engine to fail. Whenever you get your serpentine belt replaced at your local Clinton service center, it`s a good idea to have the belt tensioner replaced as well.
Bad Serpentine Belts Cause Vehicle Performance Issues

If your serpentine belt is failing, you may notice performance issues with your vehicle. The vehicle may frequently overheat. Your air conditioning or power steering may fail to work or not work properly.

As we mentioned early, a serpentine belt delivers power to your alternator, power steering pump, and air conditioning compressor. In some cases, it also supplies power to your water pump.
The car may continue to run for a moment if the ac compressor belt breaks, but not for long. The belt also powers the alternator, which supplies engine with continuous power. Once this fails its only a matter of time until the battery dies and you stall. Check the belts for wear by looking for cracking or fraying.
The serpentine belt “snakes” around several components of the engine, transferring mechanical power to nearly every critical part. Under normal conditions, the belt needs to be replaced every 4 to 6 years.
Modern flat belts are made with reinforced, rubberized fabric that provides strength and high friction levels with the pulley (Fig. 1). This eliminates the need for high tension, lowering shaft and bearing loads. Flat belts can transmit up to 150 hp/in.
A worn-out drive belt can put extra strain on the AC compressor, leading to compressor failure. If the drive belt is too tight, it can strain the compressor, and if the belt is too loose, it can slip off completely. Check the tension of the belt regularly and adjust as needed.
A broken serpentine belt may stop the water pump from circulating coolant through the cooling system, causing the engine can overheat.
The compressor cannot be bypassed without the use of a compressor bypass pulley. It would cost more for a bypass for the compressor than it would be to just replace the compressor pulley. Install a new pulley or pulley bearing if it can come off of the compressor and then put on a new belt.

What would cause the clutch on an ac compressor to continue to go bad after being replaced three times?
ANSWER : The compressor clutch relay on these vehicles are a known cause of sticking on the compressor clutch and overheating the A/C compressor clutch coil. Replace the A/C relay to see if it cures the clutch going bad the next time you do a compressor clutch replacement, or replace it now if you have just replaced the clutch.

No one can replace AC compressor belt after it snapped
ANSWER : Hello. In order to install a new belt, you will need to use a torx bit on the tensioner to move it. These tensioners are not easy to move and the torx is easy to strip out. I usually use the torx with a swivel head ratchet to access the tensioner. Once moved, it can be locked in place with a cotter pin while replacing the belt. If you would like to have this repaired, consider YourMechanic, as a certified mechanic can come to your home or office to replace your belt using the appropriate tools.

When replacing the AC Compressor, do I need to replace both expansion valves as well or just the front
ANSWER : Hi there. Anytime you replace major air conditioning system components like the AC compressor, it’s recommended to purchase all supporting hardware and replace it at the same time. AC works as a series of individual components working efficiently together to create cool air that flows into your cabin. As such, if you’re replacing the front expansion valve, it’s a good idea to replace the rear at the same time. This increases overall efficiency of the system, reduces the potential of small component failure and allows the parts you replaced to last longer.

My harmonic balancer/crankshaft pulley broke in my 1996 3000GT. When installing new one, I noticed that part of the drive belt tha
ANSWER : Hi there. Absolutely, there is a chance that there could be a damaged timing belt or it has jumped time. However, there is also the possibility that the debris has damaged the crank/cam position sensors. With a capable scan tool/ oscilloscope the sensor signals can be inspected. I suggest having a qualified technician perform an inspection to avoid replacing unnecessary parts. Your Mechanic has several technicians that can assist you with a car does not start inspection.

hey i had a belt break while traveling on my 2004 honda pilot. It is the small belt and not the serpentine belt. The mechanic t
ANSWER : Hello. The smaller belt is known as your timing belt, and it works inside the engine to keep mechanical components aligned with each other during the compression cycle. The serpentine belt, which is the big belt, drives the alternator, water pump, AC compressor, and a couple of other components. If the small belt broke it is likely the timing belt. This will cause the car to stall, lights to illuminate, and can even cause serious damage to the engine. Typically replacing a timing belt is a lot more complicated and expensive than replacing a serpentine belt. You may want to receive a second opinion on the car before you go ahead with repairs.

if the AC compressor is seized can the belt smoke when it is turned on?
ANSWER : Hi and thanks for contacting YourMechanic. If a serpentine belt goes around an a/c compressor clutch pulley and the compressor is locked up, it is okay to have the belt as long as the a/c compressor clutch is not activated. If you saw smoke coming from the belt, then either the a/c compressor clutch was engaged or the clutch was seized to the compressor shaft. Within doubt, if you need to operate your vehicle without the a/c, you can purchase a serpentine belt that is shorter in design to bypass the a/c compressor. Keep in mind that when you want to use the defogger for your windshield, it works only with the a/c working. I recommend fixing the a/c compressor issue so the vehicle is working in normal conditions. If you need assistance with your serpentine belt, then seek out a professional, preferably a professional from YourMechanic to help you.

Serpentine belt broke, replaced it but lost AC. It broke again 2 days later
ANSWER : It would’ve been helpful to know if the A/C was working fine or having a problem when the first belt broke. I suspect that the A/C pulley is binding, causing the second and first belt to break. If the A/C was working good right up to the first belt breaking then the first belt may have gotten caught up in the A/C pulley and clutch. This would cause the lack of A/C engagement and pulley to bind. Either way it may be caused by the A/C compressor.

The clutch and pulley should be inspected to see if they are faulty or if the old belt was binding it. I’d suggest getting the A/C inspected by a qualified mechanic, such as one from YourMechanic. Once on site, a mechanic will be able to diagnose the symptoms you’ve described and help you make the necessary repairs.
