Chevette Heater Core

[Eshiku]

anyone have this heater core, do you need a barb mod for it to fit on 1/2 tubbing. if so how is the barb mod are done. sorry for all the noob questions

[asdasd]

yes lots of people have it and no, no barbs are needed. there are twoo aproaches to this. one of the inlet outlet thing is 5/8 od and the other is 3/4. if you have 1/2 id tubing you can soak the end of the tubing in boiling water for a few seconds and then try to strech it over. the other way requires the use of a saw. since the 3/4 is actually flared from a 5/8 od, you a saw or whatever you choose to saw off the tubing until it is about an inch or so away from the tank. you should now have two 5/8 od tubes coming from the heatercore. you can slip your 1/2 id tube right over it

I use the boiling water method myself. I also stick a closed set of pliers in the heated end of my 1/2ID Clearflex and then gently open the pliers by spreading the handles. This pre-stretches the tubing and makes it easier to get over the stock pipes on the Chevette HC. You may want to stick the pre-streched end back in the hot water prior to pushing it on. Not only does the hot water soften the tubing, it gives it a little lube as well.


Here is a pic to prove it works. ;)

Do they sell a shroud for that heater core? or you guys make your own shrouds? how many fans do this heater core fit?

[slaya]

I think the shroud for the JR-120 will work because from what I have heard they are basicly the same heatercores... but I never had any of them...

My advice would be to make your own and save yourself some money, unless you don't want that ghetto look.

[Eshiku]

what about carprice heater cores , do they need barb mod or they just can fit with the hot water way ?

[noxipoo]

cooling works makes shroud for the Chevette core.

or you can buy some tupperware and use that as a cooling shroud.

This is what you get when you follow the instructions in the second thread noxipoo linked to.

Do not use the one for the JR-120. This JR-120 radiator is smaller that the Chevette heater core.

Heatercoes fin area 6 1/8 x 6 1/8
120 shroud 5.5 x 5

If you do buy from D-tek pruchase the Regular Pro Heater Core shroud.

I personaly would either make my own or do the tupperware shroud.

cooling works makes one that works with most of the 6 x 6 cores including the chevette (as stated above).

cooltechnica should have it...

but you can make your own out of plexi or metal:

that is a 86 chevette core I did eons ago with fitting mods and a shroud made from plexi. it has been moved thru a few cases so it is looking a little rough. it also has flat side panels and brazed on mounting brackets. :)

the caprice cores? how much of a pain in the arse they are depends on your luck - most of them have oval fitting punch outs in the tanks - PITA factor is fairly high to fix those. side note on caprice cores - you can get 2 of them with the same model number and the fittings will be totally different.

modded '71 caprice core with metal shroud - fittings were removed and brass 1/2" barbs were added in place of the originals.
