Condenser/Oil cooler combo ? Dash air

[Jetstreamer]

Hello:

Deb, the dogs and I are shoving off in the 88 325 for Denver in 6 weeks. I have no dash air and wanted to replace the condenser/oil cooler combo, and install a new compressor..... maybe new lines. I plan to use r134, so will I need a different orifice tube?

Looking online for a p30 chevy van condenser only turns up units that have no oil cooler. Thinking about splitting the two only yields search results for transmission coolers.

Can anyone help with a parts source? Has anyone split the two into separate units and if so, what did you use?

I really want to get this working before I bake in the Kansas sun.

Regards,

Kevin

Are you talking about an oil cooler for the air conditioner?
As far as using R134a, you should put a different orifice tube in it, it works under a different pressure.
The engine oil cooler, if that is what you are talking about, goes on the opposite end of the radiator from the transmission oil cooler. You can get an aftermarket engine oil cooler, and mount it in front of all the other stuff by the radiator. Check performance 4x4 sites, they may have something you can use.

As I recall, and it's been 10 months after putting in a replacement radiator, my AC condenser has an engine oil cooler built into the bottom 25% of it with two lines running over to the oil filter. I had first planned to leave the condenser off since the dash air was inoperative, and almost started the big rig without remembering the I had not connected the hoses back up for the cooler. Could have been a disaster and an EPA emergency. That's when I realized I had a dual system and had to put that crappy condenser back on just for the oil cooler.

I'm going to call Auto Air in OKC Monday to see if they can help.

Thanks for your help,

Kevin, here's a link to engine oil coolers:

Very good! I will most likely have to separate the two which is the preferred method. I'd like to hold out for a unit that have a screw on hose rather than a hose clamp connection. I would bet a good radiator shop could solder on a threaded hose fitting to match the original.

Old thread but this will be useful info. Some P-30 chassis had installed an AC condenser w/integral oil cooler (1 unit). The oil cooler resides in the bottom portion of the unit. I'm in the process of replacing mine in my 1994 GM P-30 Southwind Storm 28ft.


The part in question is here:

In the 2nd pic you can see the oil cooler connections. On the left side is the drier bottle connection and top right the discharge line connection. The unit sits via J channel on the bottom side then is tilted forward against frame and bolt via (3) bolts.



The problem is they mounted it metal-metal and vibration can crack the tubing. Before installing use some cut to sized pieces of 'bike inner tube' and mount them where the condenser fits against any metal. This will greatly reduce shock.


The following is a schematic of the condenser/oil cooler...

The GM hose fittings for it are either sized 1/2in or 5/8 YN fittings


AC drier bottle is 3/4-16UFN
