Radiator, AC and Headers

Recommended Posts

I may not get to paint my car soon but I want to keep making progress so I've decided to tackle these three things at the same time to reduce the engine heat and make it more comfortable to drive.

Radiator:  I have a non-AC car that had AC added as a dealer option. I still have an original 20" radiator.  I went back and forth on aluminum but I hate the silver through the grille and would like to avoid electric fans since they detract from engine/exhaust sound and want to look fairly stock.  In the future I may stroke my 302 so I want to get something suitable.

I found this one that says it is a match for the original copper 24" radiator.  Any reviews/experiences?  https://www.npdlink.com/product/radiator/106094?year=1969

Air Conditioning: I have an under dash unit installed by the dealer.  My Heater controls are locked up and my heater core may be going bad.  Classic Auto air has a unit that looks just like my dealer Mark IV Deluxe system and I think I will get it but it does not replace the heater core like their true fit system does.   https://www.classicautoair.com/shop/1969-ford-mustang-daily-driver-ac-kit/

I'm thinking of removing the heater core completely and running the heather hose as a loop between the water pump and the intake manifold. It is over 100* F here now, it's not a daily driver, and I don't think I'll use the heater much.  Do y'all see any issues with this plan?  If my heater motor works when I get the controls working I'll leave it in otherwise I'll remove it and block off the firewall.

Headers: My exhaust leaks.  It is better than before but still bad enough to address it.  I have original cast iron manifolds. I have PS and C4 Trans right now but think I want to stay with Shorty Headers.  I've narrowed it down to these JBAs: https://www.npdlink.com/product/header-shorty-jba/107082?year=1969 or maybe these Hookers: https://www.summitracing.com/parts/hok-70303405rhkr

I am open to others as well but I want it to work with what I have now and if I do a 331 Stroker and possibly add an AOD or the off chance I go to a T5 in the future.

Thoughts on this or anything else I should take care of at the same time as these?

Thanks!

For the radiator, I just bought one from CJ Pony parts.  It looks very much like the one you found, but about $200 cheaper.  Sometimes you pay for what you get, and the one you found could be a much higher quality product, but how would we know?

For the AC, if you are going to go to all the trouble of a new system, I suggest the original Ford factory installed one.  You can find the parts, but it is a huge task to install it all.  In the long run, I think you will be happier with the clean look of it.

For the heater hose, you do not need it connected at all.  Mine has been disconnected for years.

My Mach is a 351w with factory AC so it came with the 24" radiator. The compressor still works to this day, but it vibrates a fair amount and bogs the engine down at idle. I've considered a Saden, but I really want the look of the original.This video from WCCC on cooling may interest you:

That video was very helpful.  Did not know about the different upper radiator hose or the upgrade to the Big Block clutch fan.

It's been years since I did mine but I'll throw my 2cts in on the off chance it may help. I'm not sure of the size but I did order the larger radiator when I did my stroker build. I would see my temp gauge climb when I was stopped in traffic during hot summer day and had to do something about it. I got with my engine builder on it and the end result is we replaced the stock fan and spaced it where it would be located in the shroud better to promote pulling air through the radiator. I haven't had any issues with cooling since. That new fan blade moves a ton more air than the original. With the hood open and doing a rev it will about blow your hat off. It is a stock Ford flex fan, not one of those aftermarket ones that like to come apart. I just removed it yesterday in preperation for pulling my engine and googled the P/N. A link is below, there are some used ones on Ebay as well. It still kind of looks original which I like.

I went with FPA long tube headers and like them pretty well. At the time they were one of the best options for a long tube that tucked up pretty well.

Determining if it is good or not is easy, as you just measure the size of the tubes, and if they are 1/2" x 1/8"  it is at least decent, and the more rows it has the better it cools if all else is the same.

I have 2 big tube radiators that I will sell for much less than that. Send me a pm if you are interested.

Hedman Elite headers are the best bang for the buck and the remflex gaskets are one of the best to use, or the soft aluminum gaskets.

Board says you can't receive messages.  Which make and model do you have?  I've found that the same one at West Coast Classic Cougars is much cheaper and you can get a kit with the big block clutch fan and new shroud.

Radiator Update:

Thanks to the help here I think I am going with this kit from WCCC.  It is complete with shroud, mounts and clutch fan setup.  I would need to get those parts anyway and th price is pretty competitive.

Still thinking about the headers.

That kit is not available, also, you should never buy a radiator unless you know exactly what size the tubes are and how many tubes there is in it.

I cleared my inbox so you should be able to leave me a message now.

I ordered it.  Maybe I got the last one?  I did the product search back to the manufacturer website.It has 3 rows and 1/2" tubes

Did you get the lower radiator brackets and insulators? The larger radiator does not bolt to the radiator support like the smaller radiator. I did the swap on my Mach 1 and it makes a huge difference in the cooling. Good luck.

Yes, it was all in the kit.  They are in the small white box in the center of the photo.  The only thing I need to go back and get is a new radiator cap but I bet my old one fits.  I test fit the top bracket to the core support and it did not look right.  I might have to do some repairs to the core support in order to get the new radiator installed.
