Dual 120 Heatercore

Sweet! Any details on this one? How did you seal it to the side so that the air goes through the rad rather then slip around the sides?

I built the outer housing with the idea that an it would enclose an internal venturi shroud so it wasn't really hard - just time consuming.

the venturi shroud that is enclosed within the external housing (the lower section that is visible in the pic) was fit to the core and then temporarily mounted so it could be positioned and fit to the outer shell. once I had everything lined up, I marked the general area for the cutouts by tracing them thru the fan cutouts, mounting holes, etc. with a sharpie marker (must have tool for modding) onto the inner venturi. From there, it isn't that hard of a job - you just take the venturi off the temp mount to the core and then position it to where it lines up with the tracings under the outer housing. once you check it for fit, you have a few options - you can line it up and then:
1. flux the edges and solder/braze it into place
2. add a layer of goop to the top of the venturi shroud, let it dry and then run a bead of goop around the seams
3. seal it in place with clear silicon
4. epoxy in place and then seal seams with weatherstrip, neoprene or cork tape (i use vapco cork tape)

they all work - it just depends on how permanent you want to make the mounting.

I gotta admit that one was a bit of a pain but it was also damn fun to build at the same time.

Doh.. To late already started on this ->

a two-day early anniversary bump.

not to be rude, but what the hell for.. didnt take the time to read through the thread, but is there any current info in here?

yep - the core mod is still the exact same as far as swapping out the fittings goes...and putting it back in plain site (at 4:30a.m. anyway) was the surest method for reminding me that I needed to add some more info on dual 120 core mods - including the 342 mod, the 199 mod and a bit more info on the 302 mod.

so...should this one sink back to the abyss and a create a newer, more organized Dual 120 mod thread or should I add it to this one? decisions, decisions.

[MaxxxRacer]

i would say make an ew one. this one is so full and confusiong i dont think our current water junkies (myself included) will get the full benefit from it. If you want you can make a new thread and put all hte mods in there and I can ask one of the mods for you and we can make it a sticky. It would be a good sticky.

My hero, looks like I'm going to have an excuse to use a torch over Spring Break now . Awesome guides.

thanks.

I really need to update it though - there are a lot of tricks up my sleeve that have not made it into this thread yet. I have come up with a fix for the barbed fitting brass 302s that makes them very usable as well as some other tweakage to the process. *note to self - update this thread*

Hey i was wondering if anyone in here would be willing to build a custom top mounted dual heatercore setup with shroud, fans and cover? Check out the disected diagram... i want the heater core to sit about 1-1.5 inches inside the case so the whole contraption isn't like 6 inches tall. :P

[aMp]

Hmmmm, does anyone in here do that?

hmmmmm. that wouldnt be that terribly hard to do. Now that I think about it, a heatercore could be modded so that it would fit just about any depth into the case (and it could be mounted that way independently of the mounting for the external box).

Do you want an enclosure as small as possible in length or are you more concerned about height?? This sounds like a interesting project.

Well kinda concerned about hight but not really that much... i mean i figured by having the core sit inside about an inch, that it would lower the height a bit and make it look more appealing...most full tower cases have about an 1" - 1.5" between the top and the psu or the first 5-1/4" bay.

[sigel]

Here's the closest pic i've seen to what i want done. Except i want an external enclosure for the fan/shroud/ and a bit of the core so it only sits in the case about 1-1.5" taking up one drivebay at the most.

Hey Weapon...PM me so we can talk!! I'm at the point where i don't care about the cover.... How much you want for a double heater core + shroud + 2x120mm fans all assmebled and shipped to canada?

[sdat1333]

alright i just read throught that whole thread and all I can say is wow.
I have a 1977 pontiac bonneville heatercore sitting here now and Im trying to figure out the easiest way to mod it. I would really like to stay away from the torch if possible because id be too afraid of melting something off thats not supposed to come off. I do want to build my shroud out of steel tho so i kno i need a torch for that. Anyways anyone kno how big in diameter it tube that comes out of the tank is? Is it a standard size?

Thanks
Sean

Oh btw where can i get one of those threading things?

[FrozenPC4Brain]

Hey sdat, a "TAP" ,"one of those threading things"
Can be found at most good hardware stores.
Take the core with you and you could find some tube size to fit over it easy also
I just measured a pc I had cut off, 0.611 range, 39/64th's or 5/8 , (.625)
un-cut, .622 and the raised part .710
I have done two and the easyest way for me was to cut off with hacksaw and solder pipe fittings into the tube remaning, you will learn the torch just try it!
Do have water, fire est, BEER, and maybe a friend handy!

goodluck

[sdat1333]

k thanks frozen
Yesterday I cut the pipe off maybe an inch after it comes out of the core, and then I used a 5/8 inch ID thing that fits over the pipe and the other end has threads on the inside. It was a snug fit and i used JB Weld to secure it. I would love to learn to weld with a torch I just dont want my first time to be on a sensitive heatercore so I will buy a torch and learn while making my steel shroud.

[sdat1333]

just wanted to say thanks to everyone, i have modded my core and made an alluminium shroud, couldnt have done it w/o u guys

[moonlightcheese]

i wish someone would sticky this. i think i'm going to try doing the heatercore conversion myself. i go the torch and such. btw... what happened to the pics in this thread? why do pics disappear on this forum? is there some special type of pruning goin on?

oh and i had a question. where can i find 3/8"NPT x 1/2" barb fittings? i've looked on a few sites and can't find it anywhere. nothing at home depot either (just 5/8"NPTx1/2"barb there).

mcmaster carr has just about anything you need in the way of barbed fittings.

If you need a local source, check with mom and pop type auto parts stores -- if they do not have them, they can usually order them. NAPA autoparts stores often carry them as well.

dead pics? I will check my pic links later - they are hosted on my private account so they should all still be working.

*edit - cox apparently got my storage space switched over -- most of the pic links have now been repaired....and I now have 5 times the storage space I used to have for pics, etc. time for some more weapon projects to fill up all that empty space.

[douirc]

i live in a highrise and don't have all these wonderful tools available to me, or a place to do the work, so i'm wondering:

1) if i have the local hardware store hacksaw the tube ends off, can i heat up clearflex 60 with a blowdryer and slip it over the ends?

2) will DD's $15 shroud fit the '77 bonny heatercore?

and off topic, have you benched your heatercore against some of the commercial products, like the BIPII or PA120.2?

thanks for the info, and great job on the post!
