How do you replace the orifice tube on a 2000 Mercury Marquis
It doesn't have an orifice tube. It has an expansion valve that is located inside of the evaporator box. The evaporator assembly will have to be removed and taken apart to replace the expansion valve.
To remove the orifice tube on a 1999 Dodge Ram 3500 you need to cut the tube out of the liquid line. Kits are available at your local auto parts store to replace the orifice tube once you have removed it.
1995 nissan pickup has a expansion valve rather than a orfice tube and is located on the evap.
An orifice tube can be removed on the 1999 Dodge Ram 3500 by cutting it out of the liquid line. It is actually easier to replace the whole evaporator tube than just the orifice tube.
It is located inside of a line that routes off of the condenser and splits between the front and rear A/C sections. The line with the orifice tube heads to the firewall on the passenger side of the vehicle. You'll see a crimped area on the line, where the orifice tube is located. I don't believe you can easily replace the orifice tube without cutting/repairing the line or replacing the whole line assembly. The line has several bends negating pulling the orifice tube out. Pretty inconvenient. The rear A/C uses an expansion valve.
Most orifice tubes are placed in the high pressure line to the evaporator at the fire wall connection. You will have to empty the freon from the system to replace the orifice tube which is not very expensive (the tube, that is).
Best way is to replace the entire line , alternate methode is to cut the orifice out of the line and replace it with an orifice tube repair kit. Personally i change the whole line.
If you mean the orifice tube, it is in the low pressure line. If there is a hex nut in the line, you can separate the two parts and remove the orifice tube. If there is no nut, just a crimp, the line must be cut and a repair kit installed to contain the new orifice tube.
