what does a thermal expansion valve look like

Bal`thzar · 01-28-2010, 2:11 AM

First thanks for all of the help in my first thread. Now that I have a service manual I am having a hard time idenifying the thermal expansion valve.

my airconditioner works then all of the refridgerent gets trapped on the other side of the valve and it doesn't let it bleed back into the compressor unless I turn it off and let the car sit.

so looking through the service manual I can't seem to find the thermal expansion valve. that is the term used here in New Zealand. I am hoping maybe its known under a different name in the service manual. I know its in the dash.

anyone can give me a hand on a different name or a description of what it looks like, I have the diagrams of the heating and cooling system, but still having a hard time.

Part No. 13 in the diagram is the expansion valve.

Note, the expansion valve could be faulty or debris could be intermittently blocking the valve. If it's debris, the system may need to be flushed to clear the debris, else a replacement expansion valve may not fix the problem. In the case of debris, the evaporator needs to be replaced as it's difficult to effectively flush, and same for the condensor.

This sounds harsh, but less harsh than going through an extensive repair and winding up w/ same problem.

Here in states, used parts are an effective method of reducing repair costs dramatically compared to purchase of OEM parts. I've had excellent results w/ used AC parts.

good luck

The 013 and the 023 are the same, too.

anyone got a link to the schematic that has part 13 on it because i can't find it in the service manual

I have found 3 different parts that are listed to work, 2 of the expansion valves have a thermostat and a secondary connector and one just has a thermostat. here is a link

I am not sure of the difference. I am wondering if the secondary connector connects to the console thermostat if there is an internal one.

any ideas guys

From diagram, your expansion valve has both a pressure bias tube and a thermal sensor tube. Only connections are to the evaporator. Sensor bulb is pushed into fins of evaporator to sense evap temp.

good luck
