Step by step instructions on Expansion valve.

[troutdog]

This was from my 2002 Montero Sport 3.0 2WD. I was trying to help anyone with this problem. I give you Step be Step instructions on how to change your expansion valve.
If you can change brakes you can do this. My Expansion valve WAS clogged. It was making my compressor kick on and off. My AC is now Ice Cold.

Here are the instructions:

Awesome Job!!! Trout Dog... Also good note about having your system evacuated prior to disassembly.

Thanks, I wanted to give a little more information but I could only have so many words on photobucket. I hope my spelling was correct, .

How often did your compressor kick on and off. Mine kicks on and every about every 30 seconds.

My system was full of freon and still cut on\off bout every 2 sec. Over about a month it started doing it every 5 min, then every 2 min, then every 30 sec,, till it so bad it was doing it every 2 sec.
Also the hose coming from the condenser was shaking violently, like there was a restriction in the system. Here is a video of what it was doing before I changed the expansion valve.

sure helped me. although my symptoms were different. my compressor would seize up due to the expansion valve being clogged... the belt would slip and make an embarrassing squeal. Not to mention the air would be warm at that point. New shraeder valves, expansion joint and 134a was much cheaper than a possibly destroyed compressor.
