Confusion about Bonneville Heater Core

post #1 of 6
Thread Starter 
Ok, so Ive been reading a lot of conflicting information about these heater cores, and now Im officially confused...

First off, do I buy the heater core with or without A/C? Ive heard people say both that the one with A/C cools better, and that it cools worse than the one without A/C. Ive also heard that the one with A/C has angled tubing, making it hard to use in some situations. Which of this is true/untrue?


Also, I need some help figuring out how to install the barbs on this. According to this thread, these are the parts I would need:

However, they look like they are soldered on (I have no soldering skills ). Could I use JB Weld instead?


Any input appreciated.

You could PM that same gent & ask him how much he'd charge to do it for you ... I own 2 personally & will attest to his workmanship

The heater core idea is for those that are comfortable doing plumbing work. It actually isn't that difficult to do - provided you buy the right tools and the correct fittings.

If memory serves the one WITHOUT AC is the one to get. The tubing is in the correct position to have 1/2in compression fittings(for say Tigon tubing) soldered on. If this is to daunting of a task, I would whole hearted look somewhere else. Yes the premade stuff is more expensive, but you can't burn yourself if you don't use a map gas torch(the yellow one;propane[blue] takes too long to heat up).

There are several good alternatives that can be assembled with simple handtools, otherwise ask Ira-K if he has any tips. He is this forums Obi-Wan on such matters.

i just sawed off the tubes so that both were 1/2 size and JB welded on some fittings. works great with no leaks.

^^^^Thats a nice looking job you did there...

I think fstfrddy was selling modded Bonnie's with his barbs on them...You might want to check with him....

You can get them at DD to...Heater Core..

If you J&B weld them you might want to try this new kind out, if you don't already have any...I used some on some loose rivets on the bottom of my boat last year and its still not leaking, petty good as much beating as a boat bottom takes...



Soldering them isn't really that much of a pain if you have a propane torch..Just flux the union real well then heat it up good and start feeding solder into it on the side opposite your torch, it will suck solder into the whole joint that way, work it around till its full...

Ok well I just got back from autozone and they didnt have any cores in stock . I also checked Kragen, but they wanted $39.99, which is too much. Im either gonna check other local parts stores, or go back to autozone and have them order one for me ($25.99). I might even look for a cheap used one here at OCN, or another forum. (I would make a wanted thread here, but I dont have enough rep ).


Oh, and just some advice for people buying a heater core from an auto parts store. DO NOT tell them you are using it for computer watercooling. I made the mistake of doing so at autozone, and the guy just looked at me like I was from Mars. Then he said, pointing at the little dell on the counter, "well these computers here stay on all day and they never overheat." I tried to explain overclocking to him, and...well.. it wasnt pretty. The guy still had no idea what the heck I was talking about. Just save yourself the pain of explaining, and dont say its for a pc, lol.
