Question about Air Tools & Compressors

1 Answer

I have broken off a Orifice tube in a 99 blazer and can't get it out. Any suggestions? It is all the way at the back of the tube. Do I need to change out the evaporator and how do I do that?

Replace the whole thing. There are retrofit kits for it. You may have to cut the tubing to do it. Then you put in the kit and make sure all the seals are tight. Otherwise you may need to use a set of oring picks to see if you can get it out. Be careful that you dont mar the inside of the tube though

Changing ac expansion valve on 05chevy trail blazer

Late models do not have an expansion tube as such, I think. Rather you have an orifice tube, usually located in the line where the high side line goes into the evaporator fitting under the hood near the firewall.

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 orifice tube located in the a/c system

Hi, Orifice tubes are located in the high pressure line where it goes into the evaporator (close to firewall) or the condenser ( close to radiator) or in the line itself. I believe in my jimmy (about the same as a blazer) it was near the firewall where the high pressure line unscrews. Unscrew the line (think its a large coupler) and it should be inside there. Clean the cavity of any dirt or debris well and note the direction of the old orifice for installation.

Ac cycles on 92 blazer ,new compressor,low switch bad?

Did you replace the dryer,and the orifice tube?If the orifice tube was not replaced,this is most likely the problem,what are the pressures while it is running,and how much freon is in the system?If the system does not have enough freon it it,it will do this,but if it does,the cycling ac compressor is because of the orifice tube,if the system was not flushed out,and there was a new orifice tube installed ,then it is stopped up again.Let me know something so I can help.

Where is the orifice tube located in the a/c system?

The orifice tube should be located inside of the metal AC line from the condenser. The discharge hose (from the compressor) connects to the top on the condenser (inlet). The orifice tube mounts in the bottom of the condenser (outlet to the evaporator). The outlet tube of the condenser has a 45º upward angle. If it is not in that location it will be farther out on the same line where it connects. Here is a diagram that might help.

When changing A/C compressor on 99' chevy suburban 1500 what all needs to be changed or done besides the flush, vacuum and freon.

there is either an orifice tube or a expansion valve. both do the same job. however, the orifice tube should be replaced. it will filter small particles from the system and gets clogged. i would also replace the accumulater or receiver/dryer and condensor. if your compressor went bad chances are there is a lot of debris in the system. flushing doesn't always remove the debris. there is much more info on the internet regarding this subject. as well as videos on you tube
