UNdersized 1996 GM Truck Condenser questions

Munchies on Thu October 02, 2014 4:09 PM User is offline

Year: 1996
Make: GMC
Model: Suburban K2500 w/rearAC
Engine Size: 7.4L
Refrigerant Type: 134
Country of Origin: United States

Hello!
Had some leaks in my hose/manifold assembly, and I opted to replace it with a acdelco replacement. Looks great, all goodyear hose etc.
Problems started when the connections to the condenser were to be removed. Totally fused together. I am usually really good at this sort of thing. Work on old diesel gensets and deal with lots of old fasteners.
Heat and penetrating oil, and time. FInally got them off. Upper condenser side fitting is totally destroyed. Lower is bad too.
I bought a new condenser after poking around at available options and it sounded like most would be undersized and have to modify brackets and such. I found one labeled "Full Size" sweet!

Not so much.
I would prefer to not have to do any fab work right now. I just want to get this thing done. Anyone know of a full sized condenser? The ACdelco appears to be undersized as well but they sell new bushings, although I cant imagine how it will help if its the same size as what I have here.

Looking to the voice of experience here. What would you do?

There was a 29 inch core, AC Delco sells retrofit brackets for the smaller 27 inch core.

This is the only 29" unit I can find online:

29" GMC condensr

I have no idea on that brand's quality however. I would call AMA and ask if they have a source for a quality 29" replacement.

Your old condenser is a serpentine type and the replacement is parallel flow, which is more efficient so you may not have a problem with it being slightly smaller.

Make sure the lines get hooked up properly, the line from the compressor goes in to the top and the liquid comes out the bottom to go to the OT and rear TXV.

I'm getting this for my Caprice. SHould be large and in charge enough for your car too, since this was designed for dual AC systems: http://www.summitracing.com/parts/vta-037030-ovr

SOrry for blank post!

Thats the condenser I ordered. Well. I took the part number and ran with it. Realised its an APDI # and went from there. I got this specific one http://www.ebay.com/itm/171457280531?_trksid=p2059210.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT


What you see is what comes when ordering that lol....

APDI Specs
Construction: Parallel Flow
Core Depth: 1
Core Height: 15 3/8
Core Length: 29 1/8
Inlet Type: M20x1.5 # 8 Male O Ring
Outlet Type: M20x1.5 # 8 Male O Ring

I realize the PF is more efficient, and thats probably a good thing. Big black suburban is HOT..

grumble grumble..

Munchies:

Now you see why I said to call AMA. You bought a part on e-bay that was cross referenced as a replacement. No surprise you did not get what you wanted, there is no size listed in that auction at all. Call AMA 602-233-0090


Viceroy:

Why would you pay that much for a universal condenser? AMA has them all the way to 18.75" x 29.5" for half that price
Universal Parallel Flow Condensers

Hrm. I'll have to take measurements. the 18.75 might be a little too high. The lower ones are a little short on size.

Thanks

I see what you mean by the parallel flows having greater efficiency. AC Delco, as it turns out, has a parallel flow replacement for my 1 3/8" thick condenser. It's .7" thick. Wow. The Delco direct fit unit is not much more than the universal.

Just had a crazy idea. How would doubling up one parallel flow condenser in front of another work out? Like the equivalent of making a 2-core radiator? Two of those universal ones would fit perfectly in the OEM saddles. Should increase capacity a bit, and increase flow, no?
