Old Style Heater Assembly

TC Cobra · #1 (**permalink**) 10-12-2002, 04:40 PM

After too many months of dormancy, I'm getting back to completing my project! I've kept up with this forum for several weeks now and I am impressed with the level of passion and camaraderie amongst us Cobra enthusiasts. Thanks in advance for your assistance with this and probably more needs for help.

I have the old style heater unit (circa 1996)and I have two questions/concerns:
1. When the heater core is installed in the upper housing I don't see how the incoming air will circulate through the core to do it's job.
2. More importantly, there isn't a way (per the instructions in the CR manual)to secure the core in the housing. If it is allowed to move at all from a tight fit with the end of the housing it interfers with the defroster flapper.

I know CR has gone to the newer modular Vintage Air assembly, but I'd rather put the $500 cost into something that makes noise and/or speed.

Suggestions/ideas from the experts will be much appreciated.

Dwain,
For one,the heater core sits in the box really tight, especially with the little rubber seal they give you. You may have to trim the heater door a little or a lot. But definatley trim until it moves easily.

Assembling the heater box is not the problem with the old system, although they are a pain, it's the Fan module that fits in the passangers footwell area. Now that is a real pain to put in and takes up valuable foot space.

The fan draws air in from the foot well area, forces it into the core and then out the vents. Beautifull set up really. Especially since the Vintage air type systmes hadn't been invented when CR's started shipping the Heat/Def. package.

Want a new style call me... $295.00 including shipping. We're a VA dealer.

Throw that old heater away. It will never work properly and takes up to much space. Do yourself a big favor and buy the Vintage unit. You will be happier in the long run.

Thanks DV & Don for your replies and candor.

Do you guys use the compact unit or the "regular" size one?

Is there a way to get outside air through the system, or is that a big issue?

Thanks, again!

TC,
Use the compact unit.
Out side air!? Fella, in a Cobra, it's ALL outside air!

DV,
Ya gotta point!...

(I was wondering about Fall in Minnesota with the top on)

Thanks!

I combined (butchered) the OEM CR heater/defroster with a Vintage Air unit that works.

VA blower and core in modified CR enclosure above passenger side footwell behind WSW motor. Plywood air box to modified CR air distribution box centered on trans tunnel. (Plywood air box for AC evap coil should I attempt AC install later)

Works surprisingly well, but disproportionate with time required to modify.
