chev heater core

[Eckowear]

Does this heater core come with 1/2 barbs from auto zone, or do we have to install them ourselves? How hard is it to install barbs on a heater core?

I think it comes with 5/8" ID ... you can cut off part of the existing barb and "solder" a barb to it ... what I did with my ford HC was sweat a copper elbow with a copper tube already sweated to it.

I used the 1976 Chevy impala/caprice heater core. I just JB welded the barbs into the tubes.

The Chevette heater core I have had one 1/2" and one 5/8".

But the larger one is swaged to 5/8"- about 2" from the end it also was 1/2".

I had planned on cutting them back anyway as they were too long....Perfect fit after the ends were cut to length- all modding needed was done. :)

Its also very EZ to stretch 1/2in ID tubing over the 5/8in fittings, thats what i did.

What stryder said is true, all you have to do is heat the tubing in some boiling water and stretch it over the fitting. After it cools and molds to the fitting it is almost impossible to get off. ;)

LoL you don't even have to do that i it's good stretchy tubing...
