99 Mitsubishi Montero Sport 3.0

BIG on Sat May 09, 2009 2:48 PM User is offline

Where is the expansion valve or orifice tube (which one does it have?) located on my 99 Montero Sport?
I can't easily tell from looking under the hood so I was wondering if it might be under the dash close to the evaporator.

Thanks for your help.

Should be an expansion valve, and should be located inside the evaporator box..Hope this helps..

Are you familiar with these Montero Sports enough to know what, in particular, has to be removed to get to the expansion valve to replace or repair it. I just wonder if the entire dash has to be removed or if it is accessible simply by removing the glove box? Also, is it possible that the expansion valve can get stopped up or isn't working properly such that it is restricting the flow of refrigerant back to the compressor? I have terrible vent temps all the time but they are better (colder air) at idle. When the car is running higher rpms down the road with good air flow through the condensor my vent temps go up slightly. I thought I might have a restriction. Thanks for any info or comments.

Pretty straight foward. One or two bolts removal from inside vehicle (one is at the top of box). Remove refrigerant lines and wiring connectors.

It seems the evaporator is all enclosed in a plastic housing. Do I have to remove the dash and this plastic from around the evaporator to get to the expansion valve? Also, is it possible (common?) that my expansion valve could be stuck or working improperly and preventing refrigerant from getting back to my compressor?

Pressures would help us help you, no one can say you have a stuck expansion valve without knowing what the problem is.. The evap case is under the dash, but not hard to remove. a subscription to Alldata for your car is a great investment and will give you the step by step procedure for changing the expansion valve, but you really should give us more information before digging into it...

I will get some pressure on my car this weekend and post them. I have the factory (OEM) Repair manual on CD for my car but just haven't been able to find detailed info on the AC system such as removal procedure for the expansion valve, etc. It must be there though since this is what appears to be the complete Mitsubishi manual to the vehicle.
