Hey all-

Just bought a 95 DX 1.8L and the only issue is the AC doesn't work. After popping the hood, I saw no belt on the compressor.

The problem is, I don't see any open pulleys that a belt could even run on. I ordered this belt because ebay and amazon both say it fits, but it's very short and I don't understand where it could even run to from the compressor.

Does anyone have a diagram? Google shows one extremely long belt running everything down there, but I don't see how that's possible. Even better would be photos of your 95 DX.

I would really appreciate any help as I have a 2-day driving trip coming up! Thanks!

Can you post some pics of what you're looking at under the hood?

Also, this car has no serpentine belt but individual accessory belts to drive each accessory. The belt (mislabeled as serpentine belt in the description of it) you linked happens to fit the power steering not the AC:

Timing Belt: CD235/TB235

Power Steering: 3PK630 to 3PK635

AC/crank: 4PK865 to 4PK875

Alternator: 5PK965 to 5PK970

I have a feeling the previous owner took the belt off for a reason, like maybe the compressor is seized or something. Does the compressor pulley turn by hand easily?

The first number indicates the number of ribs on the belt (3PK, 4PK, etc.), so right there you can tell it's the wrong belt for the pulley. The last few digits is the length in millimeters I believe.

Thanks!

It's dark out now, but I can tell you the AC compressor is directly under the alternator, which does have a belt. I guess my only questions now are how/where to run the correct belt, and which length I need.

The compressor spins fine, and I see the reason the belt wore out. The compressor pulley and belt were rubbing on one of the AC metal pipes. Not sure how the pipe ended up in the way to begin with, but I can easily zip tie it out of the way.

Also -- do you have the genuine Toyota part number for the AC/crank belt?

To get the genuine Toyota part numbers, go to www.toyotapartsdeal.com, put in your VIN, then go to Engine-->V-Belt. They probably each list a "Replaced by" part number which is an aftermarket belt.

The AC belt should go around a second pulley on the crankshaft closer to the engine than the alternator/water pump belt. You need to take the alternator belt off first to put the AC belt on. There should be a tensioner pulley behind and under the alternator that the AC belt goes around, and this is used to tighten the AC belt.

You're a saint. Thanks for explaining all of this. I know other people will stumble on this thread in the future and find it useful.

For the record, the Genuine Toyota part number was 90082-93002, the aftermarket part number was 99364-20870-78, and the Bando equivalent part number is 4PK875. From my understanding they are high quality and much cheaper. Ordered mine for 6.85 on ebay.

I am about to head to work but later on I will draw up a diagram of how the belts go. It is a bit confusing, I know when I did the water pump I just kind of threw the belts to the side and then had to figure out where they went. The PS belt is easy, so it is just two belts to figure out.

I shall diagram and post that tonight

UPDATE -

Ok so here is the diagram.
First thing you must do is remove the alternator belt, the tension is set and released by some tensioner under the front of the alternator. First loosen but do not remove that big ol long bolt on top that the alt pivots on. Then on the "front" of the engine (standing at the passenger side of the car looking at the belts) under the alt there is a bolt to loosen, then the side of the alternator there is this bolt you loosen that releases tension. When using a wrench or ratchet, cover up the part of the radiator that the wrench might bang on.

You can then loosen the idler if need be. It works in a similar fashion, loosen the bolt in the middle of the idler then the bolt on top adjusts it up and down.
Install the A/C belt, set the tension, tighten the bolt in the center of the idler.

Installing the alternator belt is the reverse of removal. But yes, the alternator belt must be removed to get to the AC (and also power steering) belts.

As far as how much to set tension, I just set the belts so there is about less than 1/4 inch "give" if I press with a little force. There is a proper way to set tension but it is not very practical and a pain in the ass since there is little room to work and even less room to see the deflection measure.

The final tension I had to deal with just now when I went to the garage was there was a stupid feather-legged centipede about three inches from the light switch. If you encounter one during your repairs, make sure and murder it. It has dozens of legs and it is UUUGLY as seen in the diagram... The only time that many legs look good grouped together is when it is the Rockettes dancing. I would not mind hitting the light switch and finding them there.
