What fittings for an 89 camaro heatercore?

[Krelian]

I just bought an 89 camaro heatercore for use with my system, but what I didn't realize is that it has a 5/8" inlet and a 3/4" outlet.

Do I need smooth fitting reducers/couplers for soldering, or can I use the threaded barb fittings like they have at Becooling and Dtekcustoms?

Dodge Viper took a standard barb and smooth the thread area off and soldered the barbs in.

I used this method though:

Don't know the size as it looks like nobody sells these anymore.

So you just screwed in a couple of standard barbs after soldering in those FPT fittings?

Yes, but I only did this so I could take out the barbs...and maybe to be different.

i had one of those, and i drummeled off the ends, and 1/2' fit in perfect.

I also dremmeled off the leads, then used JB weld and 3/8" Hose barbs with 1/4" NPT thread. It worked great, and took less than 10 minutes.

I carried my heater-core rad (had some wierd smooth clamp fittings that don't match any real-world fixtures) into Home Depot and started stuffing fittings in there until I found one that fit the best. Sanded the rad clean with a dremel & brushed on a little flux for prep before jamming the fittings in. I then sweatted in some lead/tin solder with a blowtorch which worked absolutely perfectly. I'd highly recommend this to anyone. Effective and fun!

Note: this was just a wet-test and even though there was no leaking, I DID put pipe clamps on there before I mounted it in my PC

soldering is fun

i just took some 5/8 OD copper pipe, cut 2 2inch lengths of it with my pipe cutter, and desoldered the old ones and soldered in the new ones, the ID is more than 1/2inch

Does it matter if you use lead/tin solder? I heard that for pipes you were supposed to use tin with silver traces solder.

you aren't drinking the water are you

Not usually...

 

[grover]

lead/tin solder melts a whole lot easier than lead-free... and I'm, frankly, not too worried about getting trace heavy metals in my system, but there's no reason you *have* to use the lead solder.

I Did pretty much the same thing as maskedgeek except I took it a step further and soldered on two threaded female adapters (like mfpmax) and then just screwed the barbs on..
