Dang, the R&P and heater core let go at 3 years? Stranger things have happened I
guess. Heater core replacement isn't for the faint hearted.
Basic rundown is:
1: Disconnect the battery.
2: drain the cooling system.
3: Evacuate the AC. Move the accumulator out of your way.
4: Lower or remove the steering column (I suggest removing it)
5: Remove the seats, at least the passenger seat (Not necessary, but it gives you a
lot more room).
6: Remove the instrument panel according to the shop manual. It sounded too easy
until now, didn't it. See www. fordcds.com for a CD image of the shop manual. It's
usually one bolt in each lower corner, one in the lower middle, and screws along the
top near the defrost vents. Then you have to disconnect the wiring and vacuum hoses to
the HVAC. All wires around the heater\AC box, radio, HVAC controls and near the fuse
panel. Remove the IP from the car. You really need a shop manual for this step.
7: Unbolt the heater\AC box from the firewall and remove it from the car.
8: Split the heater case and R&R the heater core. Clean the case interior with
bleach or your favorite cleaner while you're there. You will thank me.
9: Reverse to reassemble.
If you are a competant DIYer, you can do it. If you are a novice, well, you can do
it but you'll make up more than a few new four letter words to add to your
vocabulary.. The main thing is, get the shop manual. Not a Haynes or Chilton. Take
your time and learn as you follow the steps.
