Reddit mentions: The best automotive air conditioning parts

Any double din should will work. Check out Crutchfield, they’ll be able to recommend a new head unit based on what you’re looking for, as well as harnesses and mounting kits needed for whatever head unit you choose. Personally I prefer this one: https://www.amazon.com/dp/B016ADOPEC/ref=cm_sw_r_cp_api_oN9YzbVW6MBE8
Crutchfield doesn’t offer it I don’t think, but from the ones I’ve seen installed it looks the best (other than the Urban Runner trim, but good luck finding that one).

The best starting place is to get your compressors model number, mine is a sanden compressor and this is what the model number should look like on the label: https://i.imgur.com/T6bfZuF.jpg

​

It is the 1K0820859Q line, that will ensure you get the correct RCV, here is the one I needed: https://www.amazon.com/gp/product/B01HC6GZSK/ref=ppx_yo_dt_b_asin_title_o03_s00?ie=UTF8&psc=1

In the product description it lists the compatible models of compressors for this one.

The anti-drainback valve is different from the filter (I think it's called a guide stalk) stem. This is the little black button that sits about 2 o'clock (ish) from the stalk in the bottom of the housing. The part I'm wanting to change is this https://www.amazon.com/Genuine-Ford-Anti-Drainback-Diesel-3C3Z6800A/dp/B00TKO1XG2 it looks like it simply pulls up out of the base but wanted to know if anyone had done it before I tried it. Thanks

I've done my own, and gotten a couple of thousand miles out of the tyre before wearing out the tyre. That was in a Fazer 6 S2. Your only on a 125 and it looks like a prime candidate for a plug.

I have this one.

But it's a bit bulky to carry, so I bought this one to take on trips which is much more convenient and still carrys plenty of plugs and the tools needed to fit one.

If I ever use the plugs in the more portable one I can simply replace them with the ones from the other kit. And it means I don't have to carry a compressor as the CO2 will be enough to get me to a garage with a pump.

Is this the part you had replaced? Because that's a higher quality one, not just a generic one, and it's still only <$50. Or did you get a different part replaced?

I forgot to link you the part.

Another option is to just spend $25 and cut the connector off this. In theory you should be able to find just the connector somewhere of course, hard part might be figuring out who to ask though.

Not sure this example is an exact match, but just to get the point across.

Buy this, and you’ll likely be golden. These fail every few years on these cars.

Here's the entire shopping list you'll need for a full job.

Condensor http://www.rockauto.com/en/moreinfo.php?pk=816244&cc=1060423&jsn=468

Drier http://www.rockauto.com/en/moreinfo.php?pk=814768&cc=1060423&jsn=487

Oriface Tube http://www.rockauto.com/en/moreinfo.php?pk=815425&cc=1060423&jsn=495

AC hose. Replace if yours is OEM, 30 years does a lot to rubber. http://www.rockauto.com/en/moreinfo.php?pk=818275&cc=1060423&jsn=510

AC seal kit http://www.rockauto.com/en/moreinfo.php?pk=1251304&cc=1060423&jsn=517

Condensor - replacement is a good idea but not necessary, this one has loads more fins than your factory one. If using old one, it MUST be flushed with a can of AC flush. http://www.rockauto.com/en/moreinfo.php?pk=3612081&cc=1060423&jsn=476&jsn=476

Your evaporator in most cases does not need replacement, but DOES need flushing.

You WILL ALSO NEED

Vacuum pump (rent from Autozone) and draw vacuum to -30hg after new system installed

Synthetic PAG 150 AC oil - add 4 oz to COMPRESSOR and 4 oz to CONDENSER https://www.amazon.com/TSI-Supercool-P150-8-PAG-150-Viscosity/dp/B01029565W

Conversion kit for AC valves to go from R12 to R134A refrigerant https://www.amazon.com/Interdynamics-VA-LH12-Conditioning-Conversion-Adapters/dp/B002G1UO8E

40 oz of r134A - so 4 of these cans. DO NOT use the AC pro or any other kind that ALSO has AC oil in the can. That will over-oil your AC system and can cause damage. This is pure r134A and cheap. dump 3 full cans in, and weigh the 4th can WITH THE GAUGE ON IT. With the AC on, fill the system until the can weighs 4oz less than what you started with. This will get you the exact amount of refrigerant you need. https://www.walmart.com/ip/Super-Tech-Refrigerant-R-134a/617476716#about-item

So total, you're looking at roughly $355 for all of it

If you don't need/want the condenser, then that drops to $295 or so.
