This is a very involved procedure! I just changed the evaporator core ($83 with shipping from Ebay) on my 1999 Plymouth Grand Voyager and it took me 10 hours. The quote from the repair shop was $800 - $1000 for labor alone! Parts that must be changed also are the receiver/drier (next to the radiator). Other parts that should be changed are the expansion valve (on the firewall) and all the O-rings. The system should be flushed and must be vacuumed down and serviced. It's also a good idea to remove the compressor, drain the oil, and look for any signs of damage - such as bits of teflon or a gray-black sludge. Don't forget to add oil to the system or you'll be needing a new compressor in no time. The oil capacity is 9 oz. and 34 oz. of R-134a.

I found this posting of photos and instructions and couldn't have changed the evap without them. Special thanks to the Dodge forum, Mr. Mahoney and Dodge Tech. Here's the link:

http://www.scsc.k12.in.us/mahoney/vanfix/

Some notes, as the instructions are somewhat ambiguos:

1. VERY IMPORTANT TIME SAVER: The steering column, instrument panel and dash all come out as a single unit! In the photos Mr. Mahoney disassembled way more than he had to. The instructions may be interpreted incorrectly and you'd be tempted to separate the steering column from the dash, or remove the instrument bezel, or the hvac controls. This is totally unnecessary! Just take your time and look at everything and check and double-check what needs removed/disconnected. Also, the step where it says to remove the nuts from the steering column at the die cast brake pedal support - those are the ones (4) that go forward to the bracket on the firewall, NOT the 4 nuts that go up to the dash! Again, the steering column comes out with the dash as a unit.

2. Some things left out of the steps: Disconnecting the parking brake light wire, disconnecting the blower fan wires, and removing the one hidden bolt from the bottom of the plenum. That bolt is near the floor, just the the left of center, and holds the bottom of the plenum to the firewall.

3. I found it much easier to get access to the engine side of the firewall by removing the alternator. This gives more room to get at the expansion valve and the 3 nuts that hold the plenum to the firewall.

4. Once you get the dash all the way out, and the plenum removed it's about 15 mins to half an hour to change the evaporator. Isn't that ironic?

I hope I haven't left anything out, and that this helps you. Let me know if there's anything else I can help with.

You will need a manual if hes never done one before. The whole dash has to come out to get to it.

I have a 1992 olds 98 regency need a evaporator core to be taken out and install a new one.How can I get the schematic diagram to do the job. ...


in my experience finding specific directions on how to do that are nearly impossible to find due to the strict EPA regulations on the use of refrigerant. but when i replaced the evaporator core on my tahoe i found it helpful to go on to youtube and search how to remove the dash. once the dash is out disconect the lines going to the evaporator core and the heater core from the engine side of the firewall. from inside the vehicle remove all screws securing the heater box to the firewall. you have to search for one or two hidden screws. looking from the engine side may make them visible. the heater box should pull out easily if not you missed a screw. once out of the vechicle remove all screws hold the box halves together, mine had about fifteen going all the way around it. open it up remove the evaporator core, clean any dirt, leaves etc. out of the box. replace core and reinstall. honestly not a very difficult job, but it is time consuming. hope this helps.

Where exactly is the orifice tube located at on a 1996 (DOHC v6)?


it's in the high pressure liquid line.

A/C Evaporator Core Orifice The A/C evaporator core orifice (19D990) should be replaced whenever the A/C compressor (19703) is replaced for lack of performance (internal damage). The A/C evaporator core orifice, located in the condenser to evaporator tube (19835), cannot be serviced in detail as a component of the line. If replacement is necessary, follow the procedure outlined for Liquid Line Removal and Installation. An orifice tube replacement service kit may be used as an optional service procedure. Refer to Section 12-00 for information regarding the use of an A/C Evaporator Core Orifice Replacement Kit E5VY-19D695-A.
-----------------------------------------------------------------------------------
A/C Evaporator Core Orifice Replacement Kit Installation
  1. Discharge A/C refrigerant system. Refer to System Discharging and Recovery as outlined.
  1. Remove condenser to evaporator tube (19835) from vehicle.
  1. Locate A/C evaporator core orifice (19D990) by three indentations or a circular recess in metal portion of the condenser to evaporator tube.


    A/C Evaporator Core Orifice Location
32c58e1.gif
  1. Note angular position of ends of condenser to evaporator tube so that it can be reassembled in correct position.
  1. Cut a 63.5 mm (2.5 inch) section from condenser to evaporator tube at A/C evaporator core orifice location. Do not cut closer than 25.4 mm (1 inch) from start of a bend in tube.


    A/C Evaporator Core Orifice Section Removed From the Liquid Line

  1. Remove contaminants from the two pieces of the condenser to evaporator tube.
  1. NOTE: The inlet half of the condenser to evaporator tube will be positioned against the A/C evaporator core orifice tabs when correctly assembled.

    Lubricate fitting with clean refrigerant oil and assemble orifice tube kit (with A/C evaporator core orifice installed) to condenser to evaporator tube. Make sure flow direction arrow is pointing toward evaporator end of the condenser to evaporator tube, and taper of each compressor ring is toward compression nut.

Leaking heater core coolent smell through the a/c


The same thing happened to my '99. I found an 'off' brand heater core locally then seached the internet to find direction on how to install. I don't remember the link, but someone had posted pictures of the step by step. Although I must say the sticking point for me was removing the screw holding the heater core to the pipes coming from the front of the car then removing the core holder.
It took me a couple of hours, not really knowing what I was doing, but went real smooth. It's fixed for around $140! And NO MORE ANTIFREEZE SMELL!!
