Looking for location of expansion valve f150 a/c

Newer units don't use an expansion valve, but instead just an orifice tube, usually located in the junction of the high side hose to the evaporator under the hood.

Vehicle is equipped with an expansion valve. It looks like this located on the passenger side fire wall

the expansion valve (TX valve) is located at the inlet side pipe of the evaporator under the dash

The expansion valve is always located at the evaporator core inlet and outlet pipe.

Here's a video from Scotty showing you how to replace your expansion valve,had mine replace not long ago,had Midas do mine. Replacing An Expansion Valve In Your Car ,hERE'S A NEW PART. Expansion Valve at AutoZone com Best Expansion Valve Parts for Cars Trucks...

Yours has a

thermal expansion valve (TXV). no orifice tube . look at fire wall where the a/c pipes go in look for this part .



The thermal expansion valve is located in the liquid line between the condenser and the evaporator. The thermal expansion valve is the dividing point for the high and the low pressure sides of the A/C system. As the refrigerant passes through the thermal expansion valve, the pressure of the refrigerant is lowered. Due to the pressure differential of the liquid refrigerant, the refrigerant will begin to vaporize at the thermal expansion valve. The thermal expansion valve also meters the amount of liquid refrigerant that can flow into the evaporator.

That valve is located just in front of the evaporator. You can look for the location that the high side connection uses to go through the firewall and it is either there or just on the other side in the plenum. However, if you replace it, you are looking at a long complicated process that should not be undertaken as a do it yourself project because it requires tools and training that you cannot short cut.

You didn't say what model 1992 Toyota it is on, so I'll have to be general. The expansion valve is usually behind or beside the condenser. I don't know if you are familiar with what those parts look like, so please don't be offended by my description. The condenser looks like a small radiator, and the expansion valve looks like a square piece of metal with a round hat on it.

Kia Sedona expansion FRONT valve located under dash, behind glove box, fan and coil. Evacuate freon first. Disconnect Freon lines from firewall., Lay right front seat back to flat horizontal position and lay on top or totally remove the seat for easier working access. Remove under dash cover, fan, glove box, coil housing, remove coil mounting bolts, remove old expansion valve. (Inspect old valve, if debris inside, blow out coil before installing new valve. If visible debris best to consider replacing REAR expansion valve and DRIER/FILTER in front of radiator too and blow out all lines and coils while servicing.) Use compressor oil to lubricate "O" rings on new FRONT or REAR expansion valve, install valve bolts, reinstall coil bolts to FRONT firewall or REAR frame, reconnect freon lines to firewall in engine compartment. Evacuate AC system, install freon (35 1/2 ounces, nominal 3 pounds), check system for leaks, check for proper operation, enjoy.

can find it under the dash with the evaporator. this is the expansion valve look like, the original.
