Brass radiators - what would you pay to repair vs replace and what can be repaired

[84-C20]

I know about distilled, I've flushed a many coolant systsns. I need to flush my park avenue here soon. Gets a little warm in the heat

What year is your PA?

There's a lot of opinions on electric fans, I hope you don't mind if I quiz you on it. Looking at your picture it looks like you have gone to a serp belt, I assume your running an upgraded alternator, for those of us that are still running factory do you know what the duel fans draw? Did you get an improvement in A/C at low speeds and idle?

I converted to a serp belt setup. It is so much cleaner and easy to maintain over v belts. I also have a Vintage Air surefit system. So the 134a system runs very cold. Those fans do draw a lot of current but, they move a tremendous amount of air. I upgraded to a 150 amp Power Master alternator. I am very impressed with PowerMaster brand-new top notch quality. I've done a lot of upgrades at once. The Pro-flo 4 efi is a dream. It maintaines a steady idle when the a/c and fans kick on. I can't imagine trying to do that with a carb.

I don't mind the Alum rads. But Since i don't own any **** box's and only Nicely Original beauty's I'm all for Brass.

If water up where your at how did it not freeze and bust. Can't remember where you said you were but I know you talk about plows and plow trucks so it must be cold!

It's hard to tell if we are looking at fluid or just residue left behind. However some global type / universal coolant is a light gold color and will look almost clear in a radiator or tank, I'd bet that's whats in there. Might be a good time to test it or change it to be sure.

A few years ago I replaced the original copper/brass with the much longer radiator used in some of the 454 2WD trucks. It was a challenge finding the longer fan shroud, and top closing panel, but I'm glad I did. During the installation I opened up the areas of the radiator core support, on the driver's side, like they would have been, had it come with the long radiator from the factory. I also found a reverse rotation 454 fan and put that on. It's been a nice upgrade. I posted a couple write-ups about it here on the square, but they're probably ruined because photobucket got so greedy and I stopped participating.

Why would a reverse rotation fan be an upgrade unless you swapped to a serpentine system?

i think its for his 1990

The 1990 TBI SBC is reverse rotation. So when putting on any fan, whether it's the OE size, or like the big 454 that I have on now, I have to source the reverse rotation versions.
