What happens if AC belt is too tight?
If a belt is too tight in a system, it can add stress to your bearings. The added stress to bearings can result into over amperage of your motor and potential motor failure. When a belt is too loose: When a belt sits loose on a pulley, the belt can slip while in motion and cause extra friction.
How tight should AC belt?
When twisted either way from the middle, the tension in the belt must not be more than 12 inch. The belt is too tight if it is twisted more. The positions do not work for the vehicle.
How do you tighten an aircon belt?
Insert the pry bar above the alternator pulley. Apply gentle pressure upwards so that it adds tension to the drive belt. Once the drive belt is moved into its desired tension, tighten the adjustment bolt to lock the belt in place. Then, torque the adjustment bolt to the manufacturer’s specifications.
Is drive belt too tight?
The required measure of tension in the serpentine belt is that it should not deflect more than ½ inch when twisted either way from the middle. If twisted more, the belt is loose, and if twisted less, the belt is too tight. Either of the positions does not work for the vehicle.
Why does my belt squeal when I turn on my AC?
A loud squeal is produced when the A/C is turned on. This symptom is usually caused by a loose or worn air conditioning compressor belt. This places a load on the engine and the drive belt that rotates the compressor. If the belt is loose or worn the belt can slip on the compressor pulley and emit a loud squeal.
How tight is too tight for a belt?
A belt should be neither too tight, nor too loose, but somewhere in between. It should be tight enough to hold your pants, but loose enough not to crinkle them and strangle your waist.
What kind of belt do I need for my Toyota 2uzfe?
For Toyota dealer replacements, you will usually find the belt is a Bando (unmarked) or Mitsuboshi. However the 2UZFE uses a Dayco as OEM. For most applications, I prefer the Gates or Bando.
Do you have to have the belt off to turn the compressor?
You don’t have to have the belt off to turn the compressor. Just turn the outermost part of the magnetic clutch. That part is connected to the compressor shaft. The clutch free wheels when not engaged.:smile:
How much tension should I put on my belt?
Click to expand… Well, feel how tight the belt is now and then make the new one a bit tighter. You should be able to deflect it about 1/8 – 1/4 inch. Not sure what the FSM specifies the tension should be. Ideally, you would use a belt tension gauge, but they run around $40-$70 and often don’t have enough clearance to use one.
What should I do if my air conditioner belt squeals?
Ideally, you would use a belt tension gauge, but they run around $40-$70 and often don’t have enough clearance to use one. Otherwise, you can use a “kricket” gage for around $10. Otherwise, you just tighten it until it no longer squeals and deflects maybe around an inch between the furthest pulleys. Go with aeromech’s deflection reading.
