I'm going to obtain the rebuilt compressor.
I'm having my system evac'd today.
Besides the obvious (new belt, compressor swap, lube o-rings or ?)
Need I seek out and replace the Expansion Tube (Orifice)?
I never saw the AC system hoses open.
Look like they never were, also.
I just had evac'd and recharged.
Two days later....
Oh well, that's racing....
Tips, thanks!

I got tips.
Salgado - $165 compressor
Unique Auto Exchange - $140 compressor (East LA, also). Good thing is they also sell the Smog Pump I need for my Blazer at $25!!
CAN YOU SAY BEST BREAKFAST BURRITOS! OLE!

BUMMER
I need purchase the expansion orifice and the accumlator tube, too. Gotta find those now...

AH the price of avoiding new car payments!

Anyone want to buy a factory fresh/ram air set up for a Camaro?
Fresh repaint, behind front nose side panels, air filters, that thing between radiator support and nose, shiny Dzus fastners, all the stuff. Looks brand new.
Email for pics...
I need $ome repairing ca$h!

 

Why would you need the expansion orifice? Isn't that the piece in the a/c hard line, located on the passenger side's main frame rail? And what piece is the accumulator "tube"? Do you mean the whole silver accumulator? JCWhitney's sells 'em for $20.

 

When I put a new compressor on 2 months ago, i replaced the orifice tube and the accumulator, also.

It's pretty straight forward. My GM/Harrison compressor didn't come with oil so we had to find out the exact amount of PAG oil to add (forgot the amount....8 oz.?????). Other than that, it's easy.
I paid $220 for a GM compressor, accumulator, o-tube and some r134.

 

This is prabably a stupid question guys , but , What are all the parts with the AC ? ....B/c a few weeks ago we had my Moms compressor changed on her car , it was $850 ..parts and labor . But another shop quoted us $1500 !!!! I could not belive that the same shop 3 years ago put a whole new AC in my car for $900 ...

Karl ,
They also changed those other parts on my moms car .So it must be a standard procedure . My uncle was telling me it has something to do with part of it being contaminated with particles from the old ac . Something like that , i dont rememver his exact words .

 

Well, the orifice tubes do get "plugged" up after time. As for the Accumulator, GM actually recommends replacement every 5 years but NOBODY does it.

If you came in to my work and had the Compressor, Accumulator and o-tube replace, plus freon re-charged.....I'd guess at around $900 in PARTS ONLY. Plus labor of 3-4 hours....$1200 easy. I don't know how people afford it. Maybe it's America's addiction to credit. Just today i replaced a fuel pump module on a 98 ******* Van....$688 for the fuel pump ONLY. Plus 3 hrs labor.... ~$1000. I could replace my fuel pump for $65.

 

hahaha ..lol lol ..im laughing my *** off ..******* van !!! wait we can say *** on here ? .

 

wait we can say *** on here ?

I see a Monty Python skit coming on now.....

Yeah I was told dryer & orifice & then system is good.
I'm happy the "AC Radiator" didn't have a pin hole in it.
Before I had this car, it was involved in a front end accident.
Not a big deal at all this AC rebuild, but, drag is that of course that AC belt is the last one!
There a place close by that has the stuff (o-ring, oils orifice & dryer).
I got a name in Torrance, also.
There is also my Business Yellow Pages (vintage 1995 Los Angeles).
Hope to have this AC going by Mon.
Really felt like a king, stuck in LA traffic, KLON 88.1 Jazz Radio & relaxing, cool.......

My Helms fctory shop manual book has the oil quantity amounts Dan.
Love having those books as reference.

 

Karl, would you be kind enough to post those exact amounts to fill a completely empty system?

I just today found out my compressor is shot, so I'm going to have to plop down some money to have it taken care of. I'm pretty sure I can replace the parts, but the refilling I'm uncertain about...

Perhaps I'll have to look into those DIY recharge kits...

 

I have the S-10 Blazer Helms book by me
This is the reference I quote.
Will be same for 3rd gen's?
Most likely almost exact oil usage...
FOR R-12 ONLY!!!

Use 525 viscosity refrigerant oil
I'm going to highlite quantities & parts.
Alot of typing & I must do things today.
BUT this is an education for myself, also.

let's go...

Discharging the CCOT AC System
When system dischagrged, measure record amount & discard the collected refrig oil (I had mine evac'd by modern system, so no knowledge how much I had).
IF quantity is 15 ml (1/2 oz or more) this amount of new 525 oil must be added to system
IF adding oil is necessary, remove the suction hose at accumlator outlet pipe connection & pour correct amount in hose or pipe, then reconnect (new o ring & proper torquing connections)

Meaurements (from the book)
R4 compressor (is what we tend to have under our hood, small, short round) - 180 ml (6 fluid ounces)

NEW oil quanitites must be added to the system during component replacement & condtions stated as follows-
WHEN THERE ARE NO SIGNS OF LEAKAGE...
Compressor -Remove, drain measure, replace same amount + 1 oz (above says 6, I am swapping out old for new rebuilt, I'll add 6 oz)
Evaporator - 3 oz (not touching
Condensor - 1 oz (not touching)
Accumulator-(I am replacing this)- remove, drain oil, replace same PLUS 2 oz for dessicant (that retained oil, soaked it up).

Only other connection I touch is the orifice (particle filter unit)

NOW....
Accumulator (I'm replacing)
R-4 Compressor system
IF new accumulator, fluid added must be 2 oz additional oil (to what poured out from original item).

Charging, usually 4 pounds.
Does this assist?

Is evaporator in the car interior at firewall - YES
Is condensor at the front at the radiator? - YES

Good luck too!
