[V6-12v] Heater Core

[Clive Young]

Toms tips are very accurate, the only thing I can think of additionally are
to make sure you disconnect the air bag power harness under he dash behind
the little panel in the drivers foot well area ( at least that is where it
was on my 90 ) before you do anything... and take your time.. the only
"while your in their" Job I can think of would be to change the ignition
switch with a FACTORY unit. The aftermarket ones are junk and I went through
3 before going to the stealership. 

If anybody wants as nap shot of what your car will look like to get an idea
before you start email me... it may change your mind :-)

Hi,

Do yourself a favor and put the little parts, nuts, bolts, etc. in
ziplock bags. Label the bags. Take your time. It'll be worth it in the
end.

There's a small (I think it's an 8mm hex head) screw visible through
the radio opening. It doesn't look like it has anything to do with the
dash, but that does in fact hold the ductwork together. You'll pull
half the ductwork out with the dash so that screw needs to be removed.

The heater box was fused to the firewall on my 90S. The insulation or
whatever it was had gotten real sticky near the top where the heater
pipes come in. It made for some grunt work getting the damn box out.

Be careful not to damage the foam on the flaps within the heater box.

Clean the new heater core thoroughly before installing. It's usually
soaked in some oily substance that'll smell prettty strongly once hot.
I cleaned mine with multiple cleaning products including carb cleaner
and still had a little bit of oily smell when I cranked up the heat.
It's gone now, thankfully...

It's not a difficult job per say, but it is a nerve wrecking one.
You'll have a very distinct "OH NO!!! MY CAR!!!" moment once you have
everything out, take a step back, and look at what you just did.

I think it took me 3-4 hours to get the dash out. Another 4-5 to get
some more parts and the heater box out. Then 5-6 or so getting
everything together. I should say that I had a pretty bad cold that
weekend so I probably wasn't firing on all cylinders. But I'd
definitely set aside a 3-day weekend for the job. Or pay somebody to
do it!
