Which A/C compressor do I have?

your multi-v belt is the one driving the forward components near your fan shroud.

it looks like your power steering belt was incorrectly ran

The 3rd track(inward) is the belt for the AC. it should only run the two accessories. its a bigger belt. then you need to run the 2nd track around the crank, water pump and ps pump. That would mean a smaller than proper belt has been riding those tracks AND misaligned, you may have damaged grooves. i would inspect.

Its taken a little while, but I have running AC!

Compressor fitted basically perfectly, with just a few tweaks needed to the lines.

Replaced:

Compressor, accumulator, condensor, pressure switch(es) o-rings, orifice tube, all lines extensively cleaned out and switched to R134a.

Also now have the correct belt running the compressor in the correct maner.

System held vacuum perfectly and is blowing ice cold. Compressor cycles in and out as expected.

In the interior, ive only got cold air via the foot level vents - so thats the next mystery to tackle. But good progress!

Do you daily your truck, is this a good condition keep it clean situation> or do you keep a pint of PS fluid in by the battery for that leaky but not so fast ps hose thats coated that half of the engine bay but works so dont bother??
I ask because if you dont mind cluttter or want to use some of your AC compressor for a larger than itself goal,


That shiny body would be a fantastic place to right down quantity, part numbers, or a personal note if you needed it of your new PN (easy peasy, reminds you of the mfg, and put a date on it)

This stuff if you use the right marker wont come of even if youre leaning on it trying to work on something else if it cures right.
If you are interested in the idea

These are good from Sharpie but they are a lot unless you keep the narrow or have a real fine hand when writing. But if you have a menards, they have their own brand that is just as good, but the yellow colored one is ugly once it cures (pastel yellow vs sharpie bright yellow), but the black and white ones are great, and they also have a small diameter pen one, ,so its easier to write small

Just an idea, after a R134a swap Id make sure im marking how much PAG oil in the whole system(calculate if your parts came oiled and how much added), t he color or pn orifice tube, the r134a Ounces, etc

Make sure the vacuum line from the engine bay is connected to the AC control panel that's mounted in the dash. The default operation when there is no vacuum is the air blows out the bottom heater ducts. Thats the easy fix. If you have vacuum and the switch is working, you may have to look at the vacuum diaphragm's and see if they are moving the doors (baffle's) in the HVAC box. Thats a harder repair. Good Luck.

and the windshield, but hes likely feeling the feet only since the air flow from the lower is greater and the windshield air flow is not directly hitting a person to begin with
