A/C system replacement with rear air, guidance please.

[Jerky Arm Ape]

Alright ya'll it's in the upper 80's down here with average humidity of about 71% and I can't take it no more.

System replacement is in a 98 yukon with rear air.

I've never replaced an AC system on a vehicle but I've been a refrigeration technician for about 6 years.

I know to replace the compressor, liquid receiver, orffice(s) and expansion valve(s).
Is there anything else that Is a good idea to replace on a vehicle of this age?
Also how many orffice tubes does my system have and is there only one expansion valve?

My system has been blown down for about 3 years when the compressor seal went, rear air wasn't cold at the time either.

Also name brands? Ht6 compressor different from original?
I've been looking at four seasons brand with "upgraded compressors"

Also I do have the deal that pulls the system into a vacuum and a set of guages.
Thanks yall.

one orifice tube for front evap and one txv valve for the rear. use a delphi or delco compressor new. flush and blow it dry via nitrogen. add required oil in each required device. deep vacuum for at least 2 hrs. then charge and test.

I'd replace the condenser as well with a newer parallel flow design.
Short additional money when your in that deep and easy to do with the system open and getting vac'd and recharged.

Thanks fella's I sure do appreciate it.
I was pondering on the condenser since it is open to the elements and insects may have been stuck to it for some time causing corrosion.
Will use delphi name brand stuff as well.
Just my personal preference over delco.

 

[Jerky Arm Ape]

Well I retract that statement about the delphi parts.
All I can find from them is the compressor :-<

So I'll use a delphi compressor and delco for the rest.

Only problem I'm having is the delco condenser is an exact copy of the original model, unless my research is incorrect.
Should I use a different name brand to upgrade to the parallel model?

 

[Tbruz]

try AC Delco pn 15-6958
I used this and its 41 tubes versus original condenser with 22 tubes.

Actually I have a spare one in my garage that I installed and found the OT wouldn't fit my two door(front ac only has an OT in the condenser) versus front and back AC with OT in the line.

Ill give you a smoking deal on this one of you can use it.
Thanks

And while we're spending your money.....
add AC Delco charge hose 15-30878 to your parts list

[Jerky Arm Ape]

I may be interested, What kind of a deal are you offering?

I did add the main hoses going to the compressor to my cart, figured it may be a good idea.
Wasn't sure what the canister looking deals on the compressor end was or their function was.

 

[Tbruz]

say $75 and 1/2 the shipping cost.
PM me your zip and I'll figure out how much shipping will be from NH.
I see them on Ebay for around 110 to 120 with free shipping so I hope this can come in around $90 all in for you to make it worth your effort.
Thanks
Tbruz

BTW you are getting a new dryer/accumulator for this job correct??

 

[Jerky Arm Ape]

Yes I am getting a new dryer.
Everything I have planned to buy:
Compressor - delphi
Dryer - Ac Delco
Orffice tube - Ac Delco
Expansion valve - Ac Delco
Suction & discharge lines - Ac Delco
And your condensor.

[Tbruz]

will check shipping costs tomorrow and get back to you.

bro, you work in refrigeration. You should've done this a long time ago.

Denso makes good condensers too, and they are very reasonably priced @ around $65.

I read Sanden makes an upgraded compressor that isn't supposed to leak like the HT6 design. My compressor is still working, but the previous owner already had it replaced several years ago with an acdelco compressor.

original ht6 type:

sanden compressor:

I just worked on my a/c this week. I just bought whatever the local stores had in stock because I didn't want to wait. I ended up replacing everything except the evaporator, compressor, and the switches. The parts for these trucks are cheap enough to just replace everything, which you might as well do if it's all ripped apart. I used r152a refrigerant in mine though...

11oz of pag 150 oil for rear a/c trucks.

Only 8oz for non-rear a/c trucks.

Obviously try to split up the oil and put some in each part. Don't pour it all in the top of the compressor and start the engine. Hopefully you know that.

 

[Tbruz]

PM sent; shipping is a killer at $54.
Better off buying online with free shipping.

[Jerky Arm Ape]

Tbruz, thanks for the offer I recon I will just opt for the new one.

I will research the sanden Compressor but will probably opt for the delphi.
Has anyone used the sanden with good results?

If I made what alot of refrigeration techs. Out there made I probably wouldn't daily drive my old Yukon.
I live in a rural area and we start at 16.31 and top out at 19.49 :-<
Just getting in some years of experience so maybe I can relocate to a different area and earn a decent wage for my family doing the same thing.

Sanden is pretty cheap, I'm afraid of cheap but that doesn't mean it isn't good.
Just can't find much information on them.

 

[SunlitComet]

That is a carbon copy of the sanden that that company makes. May not be as good as good as a true sanden or oem.

 

[Jerky Arm Ape]

Oh ok.
Would a true sanden be an upgrade over a delphi compressor?

 

[SunlitComet]

Not really sanden designs and builds them but could be also label a Delco brand or Delphi brand but the Delphi relabel would be more rare. They do do it tho.

Lets put it this way tho. If sanden redesigned it for better and Delphi has not yet then get a true sanden. Delphi or Delco will catch on.

 

[Jerky Arm Ape]

Alright, thanks for the insight.

I emailed these folks to see if this is a genuine Sanden.
I'm not sure what they should cost, my interweb searches keep bringing forth the sanden style compressor and not the real deal.

 

[SunlitComet]

a new original design from delco is $205 at rock auto.

Uh btw I think ac sells clones. At least the compressor by itself on their site says it is a sanden clone.

---------- Post added at 07:53 PM ---------- Previous post was at 07:50 PM ----------

Tho they say suppliers are oem brands too.

 

[Jerky Arm Ape]

Acparts.com has where you can search for the sanden part #
I found the sanden sight, showed a 4440 for these trucks.

I searched for it and came up with this: (which shows sanden on the label)
http://acparts.com/09-4440-p-301278.html

I believe we have the genuine available here.

I think I'd still like to use ac delco for the other parts,
Acparts.com has poor descriptions and I'm not sure who makes the rest of the components.

Plus there's nothing that depicts the kit to fit models with or with out rear air

 

[SunlitComet]

Well sanden gives that 4440 model applications for hoes and heavy duty burbs whether 5.7, 7.4 or 6.5 liter engines 96-2000 years. Trucks to of course. Call sanden directly and ask them.
