Won't a straight upper outlet interfere with power steeering on a V8 H-Body?

I checked them against what I paid for my most recent non h body radiator and the were lower by 2.50 than the best price I could find elsewhere. Good call!

I wonder how many people are using the 3.8 AC rad for their v8's. Anyone here? Heres a fun fact, seems the 151 AC rad is the same part number as the 3.8 AC one. Ive heard of some people that overheated with 4cyl rads and some said they worked fine. I wonder if that could be the diffrence in the 140 and 151 radiators? I'm going to try the 151 AC rad with Taurus fan on a mild Vortec 350, mainly because its there now as an experiment. If it runs hot I have a Griffin universal to go in. Be a fun test anyhow, I'll shut it down if she hits 200 degrees.

Sunbirds were the only h-body to come with 18" tall radiators. The only ones I've seen were on factory v8s. I guess its because of the flat hood it can be taller than the others. Don't know for sure, maybe it would fit in a monza. The radiator I have now has a straight inlet. I spliced in a copper 45 degree plumbing coupler to kick it up and outward to clear the p/s pump.

WENT TO A LOCAL RAD. SHOP TODAY AND THEY FOUND A 3 CORE RADIATOR THAT HAS THE SAME DIM. AS MY STOCK 2 CORE - OBV. A LITTLE THICKER BUT NO PROB. THEY SAID THEY CAN PUT MY INLET AND OUTLETS ON THIS NEW RADIATOR FOR $20. I WILL LET YOU KNOW HOW IT TURNS OUT AND IF THE NEW THICKNESS IS PROB OR NOT. SHOULD BE ABLE TO GET OUT FOR UNDER 200 FOR A NEW ONE

Discount Radiators no longer carries the Buick Skyhawk 3-core, V-6 w/AC radiator, Part #CU533.
They list this at $148, but I tried to buy one and I was promptly refunded my money.
[Edit - maybe you can buy one today - call them first]
http://www.discountradiators.com/search ... /index.htm
Manufacturer is Spectra. There is a picture on this web page and it looks like the stock unit I pulled off of my Skyhawk:
http://prod.spectra-ssl.com/PROD/apps/e ... RS=1.07.01
Here are the specs:
1976 BUICK SKYHAWK , V6 3.8L, AC
CoreDepth: 1 7/8";
CoreHeight: 14 5/8";
CoreMaterial: Copper;
CoreWidth: 20 3/8";
InletHeader: 2 3/4" x 16 1/2";
OutletHeader: 2 3/4" x 16 1/2";
RowNo: 3;
TankMaterial: Brass;
Inlet: 1 1/2"
Outlet: 1 1/2"

Overall Dimensions are approximately 25 7/8 x 16 1/2 x 2

USA Radiator price is $182(updated 09May2010). Same 533 part number.
http://www.usaradiator.com/BUICK--SKYHAWK--1976.html
Looks like the inlet is curved upward to clear a V-8 Power Steering Pump.

Rock Auto lists it at $201 + shipping. Same 533 part number.

You could be correct. The heavy-duty 140 radiator is smaller and only has 1-core.

I think the vega 140 radiator (still available) used to have the nickname "postage stamp"

If you see one its really small compared to all the others. Only about half as long.

OK SO WHAT WILL FIT A 79 SUNBIRD W/ POWER STEERING THAT IS IN A 3 CORE. i HAVE A TWO CORE NOW AND ON A SIXTEY DEGREE DAY IT STILL RUNS 190 WITH NO THERMOSTAT. SO I KNOW IT WON'T HANDLE A 98 DEG. DAY LIKE WE HAVE IN THE SOUTH. I DON'T CARE IF I HAVE TO PUT ELECTRIC FANS ON IT INSTEAD OF A ENGINE DRIVEN ONE. I ALREADY HAVE ONE ON IT PLUS THE ENGINE FAN.

Re: Spectre CU533 Available on ebay

Postby res0o7eb » Mon Aug 17, 2009 12:05 am

The Spectra Premium CU533 3-core radiator is listed on ebay for $125.79.
Crap, the seller upped the price to $148.99
http://cgi.ebay.com/ebaymotors/ws/eBayI ... 0385469088
Seller (carparts - http://myworld.ebay.com/ebaymotors/carparts/) claims to have "more than 10 available".
Here's a new link: http://cgi.ebay.com/ebaymotors/ws/eBayI ... 0447328022

Note; I mentioned that Discount Radiators - from the original post in this thread - no longer carries the Spectre CU533 Radiator. That is based on my personal experience last spring submitting an on-line order. I was refunded my money 3-days later after an email explaining that they are not available. But, Discount Radiators still list the CU533 on their web-site for $148.

From those pics of all the radiators I don't see any that curve up like the V8 power steering needs.
