Can you over tighten AC belt?
Dear Anthony: A belt should never be over-tightened. An over-tightened belt can burn out any bearing that the belt rotates on, including alternator, power steering pump, A/C compressor, idler pulleys, etc. An over-tightened timing belt can ruin any pulley bearing it is connected with.
How much does it cost to tighten an AC belt?
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.
What happens if your belt is to tight?
If the belts are too tight, they can put a strain on the shaft (and its bearing) of the alternator, power-steering pump and even the water pump. Most belts are installed on the tight side because they take an initial stretch. It looks like the power-steering fluid level is getting low.
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.
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.
What kind of belt does a Toyota Sequoia use?
Toyota belts are made by Bando, Mitsuboshi, or Dayco. The belt on the left is an OEM Dayco belt (it says Dayco and Toyota). The belt you use depends on the application. Mistuboshi belts are not easily procured so if I do a timing belt on a Toyota, I usually get them with the kit. The kit for my Sequoia came with an OEM Dayco belt.
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.
