Replace orifice tube on 1996 chevy caprise - 1996 Chevrolet Caprice Classic

The orifice tube is inside the tubing of the A/C. Most likely in the bottom tube that comes out of the firewall.

this will help.Thanks.

best advice is the method i would use to located the orifice tube in the 2000 chevy venture. check the automotive repair book section in your local library. Most libraries have repair manuals on their automotive shelf section. find the a/c manual for your year and model car. make a copy of the page that has the information you need. you will need to make a copy because the library will not let those manuals be checked out. you might want to google for the location of the orifice tube location. I hope this helps.

Usually the orifice tube is in the lower metal line going to the condenser, possibly behind the grille. The line is bulged out wider where the tube is.

How do I remove the orifice tube without damaging my evaporator core

WHERE IS ORIFICE TUBE ON 1999 CHEVY TAHOE 5.7 LITER ENGINE.

Its a pretty tight fit..make sure theres no damage to the line its going in..put plenty of oil on the o-rings it should go

The orifice tube restricts the flow of refrigerant to the evaporator. This restriction allows high pressure liquid freon to change into low pressure freon before entering the evaporator. The orifice tube is located inside the hose running between the condenser and the evaporator. You'll need an orifice tube removal kit if you are looking to remove it.

It is located inside the condensor tube running to the evaporator.

Here are the removal/installation instructions as per alldata:

TOOLS REQUIRED

J 39400-A Halogen Leak Detector
J 26549-E Orifice Tube Remover

REMOVAL PROCEDURE
-Recover the refrigerant. Refer to Refrigerant Recovery and Recharging.
-Remove the air cleaner assembly.
-Remove the vacuum brake booster.
-Remove the condenser tube.
-Use J 26549-E in order to remove the expansion orifice tube. IMPORTANT: DO NOT use any solvents or chemicals to clean the porous plastic inlet filter of the expansion orifice tube.
-Inspect the expansion orifice tube for the following conditions and clean or replace with a new tube as indicated:
-Broken plastic frame (1); replace the tube.
Inlet filter (3) damaged or plugged with fine gritty material; replace the tube.
Inlet filter (3) coated with metal chips, flakes, or slivers; remove the coating with low pressure shop air ONLY and reuse if the filter is cleaned satisfactorily. Do NOT reuse the O-ring seals (2).

INSTALLATION PROCEDURE

IMPORTANT: Lubricate the new O-ring seals (2) with mineral base 525 viscosity refrigerant oil.
If you reuse the orifice tube, install new O-ring seals (2).
Carefully grasp the edge of the expansion orifice tube (1) without touching the inlet filter (3) and insert the expansion tube into the condenser tube until fully seated.
-Install the condenser tube.
-Install the vacuum brake booster.
-Install the air cleaner assembly.
-Evacuate and recharge the A/C system. Refer to Refrigerant Recovery and Recharging.
-Leak test the fittings of the component using J 39400-A.

there is two charge hoses that enter the firewall (engine side)
the orifice tube is inside the one on top

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.
   
   
   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.
