The following is a general removal procedure of A/C evaporator core. The evaporator is removed differently from different vehicles.
For example, a 1994 Ford Taurus/Mercury Sable instructs you to, "Using a hot knife, cut the top of the air conditioning evaporator housing between the raised outline."

Use a hacksaw or a hot knife to cut the case. Reprinted with the permission of Ford Motor Company.
But a 1993 Ford Probe manual says to simply remove the blower motor and assembly screws before separating the case halves and removing the evaporator.




The following procedure assumes that access to the evaporator has been determined.

  • Recover the refrigerant.
  • Drain the radiator if the heater hose(s) has to be removed to gain access.
  • Remove the heater hose(s), if necessary.
  • Remove any wiring harness, heat shields, brackets, covers, and braces that may restrict access to the evaporator core.
  • Remove the liquid line at the thermostatic expansion valve (TXV) or fixed orifice tube (FOT).
  • Remove the suction line at the evaporator or accumulator outlet.
  • Gain access to the evaporator core as outlined in the service manual.
  • Lift the evaporator from the vehicle.
  • Drain the oil from the evaporator into a calibrated cup.
  • For replacement, reverse the preceding procedure. First, replace the oil with the same amount and type you previously drained.

Where do you add oil after replacing AC evaporator for Saab 2001 9.3?


there most likely is no need to replace the oil as oil travels with the gas
it is normally put in through the compressor but the amount is critical as excessive oil will block the TX valve
now that you have replaced the evaporator, take it to an auto ac specialist shop , have the system evacuated right down , any oil required to be added and the correct amount of gas to be installed

How to replace evaporator ?


On what? Front or rear? You will have to evacuate the AC system using a recovery machine. Most evaporator cores are labor intensive involving the entire dash assembly of the vehicle to be removed for access/replacement. Not a job for anyone who does not have mechanical experience in Ac repairs

Where is expansion valve located


The Expansion valve is located in the evaporator box

On this year Nissan it's not to bad of a job. The dash doesn't need to be removed like the newer cars.

  1. To replace the expansion valve, you will need to discharge the AC system. Remove the two AC lines from the evaporator.
  2. Then you will need to remove the glove box
  3. Then you will need to unbolt the evaporator box
  4. Tip it back and remove.
  5. Once you have the evaporator box removed, then you can replace the expansion valve. I would also clean the evaporator box as well since you will have it removed.

Where is evaporator coil located in 2008 saturn outlook. How much should this cost to fix


Evaporator coils (evaporator) is the unit inside the car that the cold air come from in the air conditioner. They are expensive and in most instances need the dash to be removed to have them replaced. Fortunately they are seldom prone to failure, but suffer from blockage in the fins from dust build up and leakage at the pipe fittings . They have a TX valve at the inlet end which may block up but this is a replaceable unit . Get an opinion from an accredited ac specialist shop before replacing the evaporator.

I have a 1999 Toyota Rav4 that has evaporator leak so the air conditioning system is not working. How do I repair or replace the evaporator and what tools and chemicals do I need for repair?


You must remove the entire dash of the truck to replace the AC evaporator core. This is not really a do at home job. Time to complete is about 14 hours. You need special tools and a factory repair manual to get it all back together correctly.

Replace evaporator


ew. You chose an expensive car to have this to happen to.

Well, the evaporator is located behind the console and dashboard, and requires a complete disassembly of the dash board area.

It's possible for one technician to do it, but the last time I saw one done was at my local a/c garage. They were working on the city's vehicle, and it was a Dodge Dakota, late model.

It had the same problem as yours, a leaky evaporator.

They had about 30 hours into it at $50 per hour. The evaporator
was cheap, but the labor to change it is not.

Good luck on this one.

Which way does the orifice tube go? Orange end or white end to the firewall?


9 is the orifice. Freon is headed toward the evaporator in the car. The orifice has an arrow on it. Good luck, please rate. Thanks A/C Evaporator Core Orifice NOTE: The A/C evaporator core orifice (19D990) should be replaced whenever an A/C compressor (19703) is replaced.

The A/C evaporator core orifice has the following characteristics:
  • is color-coded orange
  • has a diameter of 1.46 mm (0.058 inch)
  • is located in the condenser to evaporator tube (19835)
  • has filter screens located on the inlet and outlet ends of the tube body
The A/C evaporator core orifice is the restriction in the refrigerant circuit that creates the pressure drop necessary for cooling by metering the flow of liquid refrigerant into the A/C evaporator core (19860), which reduces the pressure. Operation is as follows:
  • The inlet filter screen acts as a strainer for the liquid refrigerant flowing through the A/C evaporator core orifice.
  • O-rings on the A/C evaporator core orifice prevent the high-pressure liquid refrigerant from bypassing the A/C evaporator core orifice .
  • Adjustment or services cannot be made to the A/C evaporator core orifice assembly. It must be replaced as a unit.

Yes I know how to replace the evaporator core. It involves getting into the passenger side dash because it is pretty much where the heater core is for the heating system

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

  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.

  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.

Evaporator


You will need to remove the entire dash assembly to replace the evaporator core, unless you have a really good understanding about such work I would leave it to a professional, if you still want to do the job yourself post any questions you have about removal of the dash and I will try to help as much as possible.
