Serpentine belt bypass?

Looking at the belt diagram, it may be possible to use a shorter belt as long as the new trajectory will not cause the belt to rub on anything and looking at the engine is to only way to find that out.

Good afternoon.

They are correct. There is no belt listed for the engine without AC.

The way to do it is to remove the compressor and install a bypass pulley. That you can get from the parts store.

Then you can use your original belt.

procedure

REMOVAL

CAUTION:
- If installing a new air conditioning compressor due to an internal failure of the old unit, you must carry out the following procedures to remove contamination from the air conditioning system.
- If A/C flushing equipment is available, carry out flushing of the air conditioning system prior to installing a new air conditioning compressor.
- If A/C flushing equipment is not available, carry out filtering of the air conditioning system after a new air conditioning compressor has been installed.
- Install a new evaporator core orifice as directed by the A/C flushing or filtering procedure.
- Install a new suction accumulator as directed by the A/C flushing or filtering procedure.

- Refrigerant Compressor Oil (mineral oil) F73Z-19577-AA (Motorcraft YN-9-A) should be used to lubricate R-134a refrigerant system O-ring seals only and should not be added to R-134a refrigerant systems as an A/C compressor lubricant. PAG Refrigerant Compressor Oil F7AZ-19D589-DA (Motorcraft YN-12-C) or equivalent meeting Ford specification WSH-M1C231-B only should be used as an A/C compressor lubricant.

NOTE:
- If installing a new A/C compressor, the A/C clutch disc and hub, A/C compressor pulley and A/C clutch field coil must be inspected and transferred from the old unit to the new unit if suitable for reuse.
- Installation of a new suction accumulator is not required when repairing the air conditioning system except when there is physical evidence of system contamination from a failed A/C compressor or damage to the suction accumulator.

1. If flushing of the air conditioning system has not been performed, recover the refrigerant.
2. Remove the RH and LH cooling fans.

3. Loosen the tensioner and remove the drive belt from the A/C compressor pulley.

4. Disconnect the compressor manifold and tube assembly.
- Discard the O-ring seals.

5. Disconnect the compressor field coil electrical connector.

6. NOTE: The upper LH A/C compressor bolt must be removed with the A/C compressor.

Remove the four A/C compressor mounting bolts.

7. Remove the A/C compressor.

Hi PSILWIL:

Well, there is no specific belt made and noted for bypassing the A/C compressor. That being said, I found a couple of potentials.

This vid says to replace with the belt noted below and gives a somewhat procedure for it.

This vid says it's necessary to install the bypass pully, as I found many other sites and discussion groups that say the same thing.

If you change the belt to the one above (5060820), be sure to note somewhere/somehow the specifications of the new belt and stock number --
Top Width: .82 in
Effective Length: 82.09 in
Outside Circumference: 82.75 in
so you can find a similar one if needed at another parts store. But, Advanced Auto Parts says it does not fit as a Taurus AC bypass belt. Apparently Ford will not authorize anyone to market a bypass belt so everyone says "it will not fit" no matter the size.

If you install the AC bypass pully, then it will always be the stock size belt which every parts store has.

I would really like to know which one you choose to do. Especially if you do the belt, and it does fit!

You can use a shorter belt if you might need to do some trail and error on the belt size her is a link that shows the belt routing to help you see how to do it

Hello, I am Danny.

Can you use your phone to take a picture of the under hood sticker of the of the belt routing diagram? If you could do that and upload it here it would help. There are about six different diagrams I have here. On some vehicles they make a dummy/idler pulley to take place of the A/C compressor to use the original belt but that requires the removal of the compressor entirely. Hope this helps and feel free to ask any questions. Thanks for using 2CarPros.
Danny-

Yes you can by using this serpentine belt.

The belt designation is 822K6. Just route it like you normally would but do not include the AC Compressor.

You never stated which engine you have. That shorter belt bypass may work on the 3.0 OHV (U) motor but it will not work on the DOHC (S) motor.
The shorted belt will not clear the tensioner pulley.

I am so happy we could help you out! If you have any other questions come on back. We are always ready to help you!

First of, all Tauruses were sold with A/C, there was no option for no A/C when you go ask for the shorter belt. And, if there were an option for no A/C, simply getting a belt with no A/C does not work. What you need to do is to get a piece of rope, loop it through whatever pulleys that you need the belt to run (keep it tight), measure the length of the rope and ask for that length of a belt.

Here is how to read the belt. I'll use Goodyear for an example. You standard belt is 4060855. "40" denotes serpentine belt, "60" denotes the belt has six ribs, and "855" is the length, 85.5 inches. Supposed that you need a belt that measures 77.5 inches, you will ask your parts guy for 4060775 Goodyear Gatorback. If they don't carry Goodyear Gatorback, ask them to cross-reference to the brand they carry.

Now. here is the twist. Look at the two belt routing diagrams. Look at your 8th digit of the VIN, it will either a 2, U, or S. You may be able to bypass the A/C pulley for VIN 2 or U, but I am not so sure for VIN S. You also want to make sure that the way the pulleys run. What I mean is that if a pulley runs clockwise, it has to stay to run clockwise with the shorter belt. Can't run the opposite direction.

3.0L V6 OHV Vin "U" or "2"

3.0L V6 DOHC VIN "S"
