Heater core replacement

Hello,

I am attempting to replace the heater core in a 1992 Subaru Loyal wagon 5 speed with air conditioning. I have the dash unbolted and most things out of the way but I have two questions.

1. Is the heater core in the box to the left of the box marked A/C ? I opened up the box marked A/C and it looks like a radiator but much larger than the replacement heater core I have.

2.  I can not get the box I think has the heater core open - will I have to take the dash completely out of the car? If so how hard is it to remove the steering wheel. The steering wheel is the only thing that is holding me back from taking the dash out (I think anyway!)

Thanks for any help someone may have. Joe

Re: Heater core replacement

The radiator that you said that is in the part of the dash marked a/c is the air conditioner evaporator. The heater core is to the left of the evaporator.

Yes the dash has to come out and the steering wheel must be removed and the steering column has to be lowered in order to get the heater core out. The job is listed to take about 5 hours.

The instructions for the dash removal below are from the Alldata information website.

On models with airbags, disarm airbag system as described under MAINTENANCE PROCEDURES/AIRBAG SYSTEM DISARMING.

On all models, disconnect battery ground cable.

On all except Legacy, SVX and XT, remove instrument panel as follows:

a. Remove trim panel D from driver's side, Fig. 5.

b .Remove tapping screws from lower side of instrument panel in three places.

c. Remove clip from steering column shaft while lowering cover, if equipped.

d. Disconnect ventilation duct combined with trim panel from heater.

e. Remove fuse box attaching bolts and fuse box.

f. Disconnect fresh air ventilation cable on driver's side by removing cable from clamp on rear left side of instrument
panel and disconnecting cable from fresh air ventilation lever rod.

g. Disconnect heater control cable by removing cable from clamp on left side of heater unit and disconnecting cable from select lever rod.

h. Disconnect vacuum hoses.

I. Disconnect instrument and body harness connectors on driver's side.

j. Remove steering wheel and disconnect steering column from vehicle body.

k. Disconnect speedometer cable from rear side of combination meter.

l. Remove center tray attaching screws and tray.

m. Remove console box.

n. Remove trim panel on passenger side by removing resin clips from lower end of instrument panel in two places,   removing resin clip on pillar side and detaching trim panel from heater side.

o. Remove glove box pocket by remove screws holding hinges to lower end of pocket and detaching lock from striker.

p. Disconnect blower motor vacuum hose from upper rear side of pocket frame.

q. Disconnect electrical connectors on passenger side.

r. Remove instrument panel covers.

s. Remove instrument panel attaching bolts.

t. Disconnect radio antenna lead from rear side of instrument panel.

u. Carefully remove lower instrument panel.

Re: Heater core replacement

Thanks for the great info!

Another question though, I think I can do everything except for (j) I can go to advanced auto and borrow or rent a puller for the steering wheel but I don't know what?

j. Remove steering wheel and disconnect steering column from vehicle body.

Disconnect  steering column  means?  Thanks again and if a pic is not too much trouble  it may be a big help for me. Joe

Re: Heater core replacement

This means that you unbolt the steering column from under the dash and lower the column.

The steering wheel puller can be rented from Autozone also.
