A/C Condenser Replacement write up
This could be moved by the Admin/Mod as seen fit. Sorry that I forgot to take pictures but incase anybody else has to do this job here is a quick write up for you to read though.
This applies to og9-3 (probably work the same for the ng900 as well).
1. Remove grille, headlights, corner lights, and bumper.
2. Unplug and unbolt the horns (13mm nut)
3. loosen the clamps on the intercooler connector on both sides and remove the intercooler.
4. Unbolt the PAD connector at the receiver dryer where the A/C lines come in. It's a 10mm bolt and might be stuck on there tight. Be careful to not round the head. Once unbolted pull the hardline hoses out of the connector.
5. Next you'll see two more 10mm bolts that are attached to the circular clamp that holds the receiver dryer in place. You'll need to remove those to muscle the receiver dryer a bit when removing the condenser.
6. Disconnect the plug to the pressure switch on the condenser.
. Remove the two 8mm bolts (one at each corner) on the bottom of the condenser.
7. At this point the only thing holding the condenser in place are the two slots on the radiator which the condenser slides into. To get the condenser off of them push the radiator assembly back toward the motor from the top and lift the condenser up. Start with the left side and then move to the right side. The right side is a little tricky and this is why you unbolt the receiver dryer. You'll muscle the RD a bit down while you push the radiator assembly back and lift the condenser up. The pushing back on the radiator gives you the room you need to clear the radiator support cross member.
8. Once off of both sides drop it down to the ground.
9. Remove your receiver dryer (2 10mm bolts for the hardlines from the condenser and a phillips screw for the circlip) and your pressure switch (14mm wrench) if you need to move them to the new condenser. Make sure to use all new O-rings, 1 for the pressure switch and 4 for the receiver dryer, and to lube them with petroleum jelly to avoid ripping them during install.
10. Reinstall in reverse using the same method. Reinstall is a bit harder though as its a little difficult with only two hands to maneuver the receiver dryer and lift the condenser while pushing the radiator back. It can be done but a helper would make it easier.
11. Charge your A/C system and enjoy cold air again.
I'm knocking on wood now so that I don't have to do the blower motor, evaporator, or heater core at all. I've replaced every part of the A/C system now except for those on my 9-3.
