    Hi Mike - I'm going to put my comments in here instead of answering in case someone else wants to jump in.
    Based on the diagram I doubt you can bypass the pulley and not hit something with the belt. The book does not list an engine without ac so you would have to run a string around the pulleys to figure out the length if you want to try it.
    The gap between the water pump and the tensioner may be too much to keep the new belt tight.

Impossible to work out . check to see if there is a application that doesn't have the compressor in the system and get that belt ( good place to start is at your car spares department to see if such a belt is listed) Alternatively take a flexible tape measure and wrap it around the pulleys you want to use and read the distance . It will be a starting measurement and when you buy the belts ensure that you will be able to exchange the belt if it doesn't fit

get the a/c condensor recharged with a freon substitute, i use "red-tek 12a refrigerant", it is much safer than freon and is ozone friendly.

SOURCE: 2001 Dodge Dakota replacement serpentine belt too short (w/o air)

the parts store can give you a bigger belt just give them the part# of the belt thats to small which they have a book with the measurements of the belts, tell them you need a belt the same design but 3 inches bigger, its simple, they look in the book and get the belt i do that often at napa auto parts, some part stores have lazy workers, they dont take time to help people, try that, good luck.

2001 impala 3.8 liter belt size to bypass AC unit


You can also remove the a/c compressor and install a bypass pulley in its place. You can still use the standard belt this way, just run it to the bypass pulley instead of the a/c compressor. RockAuto has them at the link.

2001 Dodge Durango with burnt AC compressor, can I bypass with belt without removing compressor?


no because you will need to install a idler pulley off a non air engine to make things work or you may be able to buy a belt for a non air dakota that wiill work on your dorango as they both have the same power trains

Can i bypass the ac compressor on my 1992 dodge dakota 5.2l with a shorter belt from one without ac


I have a 92 Dakota with a 5.2 (318) 4x4, automatic trans. You can simply remove the ac compressor and go with a belt a bit longer then what stock non AC calls for. The idler pulley is in a slightly different location from AC to no AC engines so just getting the non AC belt won't work. I used a 5070900 / 7PK2285 for mine and it worked fine. Just a touch tight getting on. Next time I'll probably go 1/2 inch longer so a 5070905. I'm a licensed tech with 20 years in the trade in Canada, 4 years of that with a Dodge dealer.

The pully on the compressor is bad can i just leave off the compressor and bypass it with a different size belt


Yes. there are basically three ways:

1. Put in a new a/c compressor.

2. Try a smaller serpentine belt. If this model came also w/o a/c, that serpentine belt should work fine. If all Santa Fes came with a/c then like you were saying try a smaller belt. You might have to try different smaller belt sizes(as far as I know) until you really get it right, which is not easy.

3. See if they make an a/c compressor delete pully for your particular model. This is basically just a single standalone pully (dummy pully). Aftermarket companies do not make them for all models, but if they make it for yours, you can use the same serpentine belt w/o a compressor. The internet is the best place to check.

My compressor is bad on my 2000 pontiac sunfire 2.4, i am wanting to bypass the belt with a new (smaller belt) can u please tell me what size i will need


Hi,

Improve the Fixya.com experience for everyone by voting!

What you are looking for is called an 'air conditioner compressor bypass pulley'. Most chain auto parts stores have them in stock.

All you do is install the bypass pulley and use a shorter belt.

The only downside is the cost of $25-$40. That's about one-third the cost of a remanufactured unit and the labor is compatible.

All the best

Your going to have to install that belt and find out how much smaller you need it, then the parts store can lookm it up and give you the right belt, the stock belt size is 85.892 inches.see how much less you need,you dont have to be exact because it has the tensioner, with the belt on you will be able to see how much smaller and subtract it for the size i gave you,heres a napa belt # this is 1 1/2 inches smaller #25060840, heres one 6in smaller #25060790,just see how much smaller they will find the right belt, also they sell a bracket with a pulley that takes the place of the compressor but if you can bypass it then do so. hope this helps.

Just had this exact same problem with my car. Sears Automotive said that it may just be simpler to get a smaller belt and bypass the compressor. Talked to someone at another store and they suggested the same thing instead of spending a ton of money to replace the compressor. So in short, yes and that is confirmed by two mechanics.

hi there it sounds to me that the bearings are going bad on your ac/c compressor

you can bypass it by getting a smaller belt
to get a size you can take a piece of string or rope and go around the remaining pulleys like alternator power steering and crank shaft then tie a know take it to napa and have them match as close as possible then install that belt this will solve your problem until you replace the compressor
the other way is go to a salvage yard look for you make and model without a/c there will be most likely a pulley and bracket in the place of the a/c compressor
take a picture of the set up and take the pulley off including the mount bolts and then remove th compressor on your car and install the pulley and you can use the same belt
