Re: CJ-5 Heater Fan Upgrade Questions
James,
I'm not sure if your still looking for advice on this mod. I just recently
moded my blower motor. It's a fairly cheap upgrade but a pain in the *** to
complete.
I bought the upgraded motor from Schucks, part # 35587 (that's the correct
GM upgrade) I paid $30 for the motor, new.
You do not need to remove the dash or seats to get the heater housing out.
I did it at 45 years old. However, you need be able to contort your body a
little.
Getting it out is the easy part. 4 nuts and it's out.
Once out, unscrew the numerous screws on the back of the heater housing and
you get to all of the innards of the heater hosing.
Absolutely replace the heater core (Schucks part # 399210 for $40.).
Replace your old blower motor and heater core.
Now the hard part. Lining up the flapper ducts and the heater housing and
buttoning it up. That took a little finesse and time.
Now the really hard part...expand the hole to fit the new blower motor.
Read this and you will have complete success making the hole larger and it
will look like a professional install;
http://www.jeeptech.com/body/heatsup.html
I had to buy a 3 1/4" hole saw at Home depot for $20
Do not make the same mistake I made: I measured perfectly, and I made a
perfect hole. However, I couldn't get the friggin heater assembly to fit
back in. So, I absolutely hacked my beautiful hole into a jagged octagon
using a dremmel tool (it looks like ----) but the assembly more easily fit
back in.
As I look back on this I realized, I just needed to finesse the heater
assembly to line up with the holes. Have patience (unlike me) and give it a
good push and it will fit in nicely
Total Cost for the project, including the hole saw: $90
Total time...about 6 hours as I couldn't get it to fit back in. Have two or
three friends help you line up the holes.

Re: CJ-5 Heater Fan Upgrade Questions
Just an FYI.
If you have the dash off, the cussing time will be cut in half at least
'And' the heater motor will fit straight through the nice new round
hole... let alone how easy it is to hook up all ducts...
I think it is worth the 'extra' time to pull the dash.

If you have the dash off, the cussing time will be cut in half at least
'And' the heater motor will fit straight through the nice new round
hole... let alone how easy it is to hook up all ducts...
I think it is worth the 'extra' time to pull the dash.

Re: CJ-5 Heater Fan Upgrade Questions
Mike,
not having the dash off wasn't the problem (I agree it would be easier if it
was off). My problem was the hard plastic duct that runs from the air
intake on the hood down to the heater assumbly. It was this duct that caused
my problems. You are correct though, it's easier to see what's going on
with the dash off.

not having the dash off wasn't the problem (I agree it would be easier if it
was off). My problem was the hard plastic duct that runs from the air
intake on the hood down to the heater assumbly. It was this duct that caused
my problems. You are correct though, it's easier to see what's going on
with the dash off.

If this is a bigger motor too you need to consider changing the
resitor strip that gives you speeds because the stock one may fail in
time under the heavier current draw from a bigger motor.
