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.

I believe the orifice tube on this model requires the a/c pipe to be cut to install a new tube. You need to discharge the system, replace the tube, then evacuate miosture with a vacuum pump, then recharge with R134A refirgerant. Not a job for a non technical person.

The oriifce is in the line just before the evaporator that is in your car a/c heater case. It is where the liquid refrigerant turns into a vapor as it comes out of the orifice and then it absorbs heat from the air going into you car, thus blowing cold air. Moisutre in the warm air condenses and as he iar gets cold and it drains out of your evaporator and out the drain & onto the ground

SOURCE: Instructions to replace sheared off lugs / studs - 1997 Chevy

You need to remove the wheel of course. It depends on if the silverado is like the 1997 GMC 3/4 ton K2500 4x4. If so, then the easiest way is to remove the hub with the rotor because on the GMC the lug bolts go through both making them one unit. I just changed out the lugs on a 1997 GMC as mentioned above while replacing the ABS / wheel bearing hub assembly in which I had found to be the easiest procedure. Place the unit on the bench and look to locate the back of the lug nuts so you can see if there is anything else you may want to do to make things easier and then drive the lugs out in the steps that follow. If the lugs are part of the rotor and not driven through the hub assembly and into the rotor, then you would simply remove the rotor and lay it on something flat, clean and sturdy and use a drift or center punch with a persuasion tool such as a hammer to drive them out by placing the punch on the face of the sheered side of the stud and smack the punch with a hammer driving it out the back side. You then you put the new one on by pushing it through the hole from the back side of the rotor and tap it in until fully seated. Put everything back together and safe travels.

Good Luck.

Sounds like a bad ignition coil. Check for spark right after it quits Coils can and do quit working after they get hot. Also check magnetic pick up coil in distributor. After reaching operating temp computer will move the coil and a broke corroded wire loses connection. Then when engine back to cold wire is back in contact and working. Hope this helped.

Show me where the orifice tube located

Same post again? Look at two AC pipes entering heater box. One is low side (large) and one is high side (smaller). Disconnect the high side pipe union and inside the pie going into heater box is the orifice tube.

Where is the orifice tube on 99 gmc sonoma pickup

The AC orifice tube is located in one of the metal portions of your hoses. It may be identified by about a few inches from the nut you shall see four small indentations around the surface of the tube. This filter is located inside the tube and usually needs a special extractor to remove.

Good Luck

Where is the location of the ac orifice tube on 06 chevy silverado

The orifice tube is located in the line of the high pressure side of the system it maybe at the condenser or in the high pressure line. You should be able to feel a crimp in the line and the is the stop for the orifice. I believe the o6 is in the line and as I said there is a crimp in the line where the orifice is located.

What is the purpose, and what is the proper location of the orifice tube in the air conditioning system on my 1991 chevy silverado?

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.

Orfice tube location

the fixed orifice is located in the inlet tube to the evaporator core, this is where the small high pressure AC line from the compressor connects to the tube sticking out of the engine firewall, u will most likely need a special tool to remove it, here is a web link to the tool, don't damage the evaporator core by trying to remove the orifice tube without this if it is stuck down in the tube.

I have a 2003 chevy Pickup 1500 5.3. When I start the car the air is cold. I drive a few blocks then it blows warm air. What coluld the problem be

low charge or too high of a charge.
the low side should read 25 to45 psi at idle.
But, if the a/c behaves this way, there might be a restriction in the orifice tube near the firewall

Good luck to you in fixing this problem.
