where does orfice tube go show diagram
If the low side has too much pressure and the system isn't cooling properly that would be one sign that the orifice is plugged up. Removing the orifice tube and inspecting it would be the best way. If the orifice tube is loaded with metal trash, the compressor is probably on its way out. Replace the compressor, accumulator and orifice now before the compressor fills the system with trash, this you don't want to happen.
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.
The oriface tube on this vehicle is crimped into the liquid line that is located on the passenger side. The whole line must be replaced, but it is relatively cheap. Just did mine this weekend with a new dryer and compresssor.
Why, did you break your tube? The best way to fix this is to go to a salvage yard and get another tube. The diameter size of the tube is about 1/2".
On the front unit, the orifice is located in the inlet tube of the evaporator core. Find the line that runs from the condensor to the evap core. Undo that connection, and the orifice is inside the evap core tube right there.On the rear unit. there could be either an expansion valve or an orifice. I am looking at the Ford service manual, and it doesn't say. But either one will be accessed the same way. Remove the left quarter trim, and look at the lines going into the evap core. If there is an expansion valve, you will see it right away on the inlet tube(small diameter tube). If there is an orifice, it will be located inside the inlet tube of the evap core, just like the front unit.
The orifice tube is between the condenser at the radiator, and the evaporator at the firewall. The O-ringed short end goes toward the evaporator/ firewall, the longer tapered end is toward the condenser / radiator.
To choose and install a tire tube for a bike, first, determine the correct size by checking the tire sidewall. Then, select a tube that matches the size and valve type. To install, deflate the tire, remove the wheel, and insert the tube into the tire. Carefully align the valve with the hole in the rim before inflating the tube slightly. Finally, reattach the wheel and inflate the tube to the recommended pressure.
Remove tire, remove tube. Buy better rim strip. Install better rim strip. Install tire half way. Repair or buy a new tube. Install tube, Finish installing tire. Inflate tube. Stick wheel back in bike. Check the brakes/chain as needed. Go ride the bike.
You need special tools to remove the orifice. The best way is to purchase the line its in and replace it in one piece (less likely to leak too).
the tube is located in the liquid line (high pressure)line that goes from the evaporater to the condenser in front of the radiator. the high pressure line is the smaller diameter line of the 2 lines.usually on the passenger follow the thinnen a/c line until you reach a connection where it meets the lime that goes to the condenser core in front. after draining all Freon and pressure you will have to separate this connection as the orifice tube is inserted into the a/c line that goes back to the evap in firewall grab thetube firmly with a good pair of needlenose pliers.purchase the tube first so you get a idea of the size of the part you are pulling from inside the a/c line. pull and twist a bit back and forth to work the tube out make sure you get the whole tube out or new one will not install. notice all the dirt and filings stuck in the filter. get some compressor oil and wipe some on the new tube make sure you put it in the way it came out. pushit in with your thumb as much as you can then grab the tail piece of the new tube with nn pliers and push till it seats in. you should install a new oring at the connection you separated if not wipe the seal with oil
If I'm not mistaken Toyota uses expansion valves, not orifice tubes. The two airconditioned Toyotas I've owned have been that way. The expansion valve will be located inside the evaporator unit behind the dash/glove compartment. Probably not accessible without removal of the evaporator unit.
As always, the a/c system has to be completely discharged. Remove the air cleaner housing/windshield wash tank because it is also holding down the engine coolant reservoir. remove the bolts holding the reservoir in place as well as the nut holding the accumulator to the reservoir (so that both components may be shifted out of the way) the orifice tube connection should now be exposed (close to the firewall). Hold the entire connection with an adjustable wrench as the 13mm nut is removed. Once the lines are split, a pair of needle nose pliers can be used to remove the orifice tube that is tucked inside the line. good luck luck.
