I am trying to replace my ac exspanion valve in my 2005 Honda CR-V.
I can't find it and I was wondering if someone on here had a procedure and diagram on replacing it?
Can one of you all help me please?????
Really would make my wife happy....

Thank's my96Hondadriver........

 

It's bolted to the evaporator core, and you've gotta' pull the core to do the job.

cut the plastic piece where the marks are

You first need to know how you are going to re-service the AC system, I assume that you want to do this part of the job yourself but you will have it professionally recycled. You can have a shop remove what freon is in the system and that freon will remain yours if its not contaminated. YOu should get a credit for that amount on the recharge when you are done with the TXV replacement. You need new Orings and put a touch of AC oil on them, do not overtorque any fittings you put back together, the Orings do most of the work.

You would be best served to have the system made operable, unless the TXV is completely blocked, put some dye in and let it run for some time and sit for some time to try to find out if the evaporator is leaking when you remove it, the shop can take a quick look at it once you pull it out, then they can survey the rest of the system to see if you need any further work done also.

 

 

are you sure it needs replaced what were you high and low side pressure cuz the tend to make a hooting type noise when low on refridgerant .

 

Excellent blog post, I look forward to reading more.
Thank you for bringing more information to this topic for me.

 

probably because it did the typical crv thing where the compressor explodes and shoots shrapnel everywhere and kills the entire system the technical term is black death

 

o yeh those thing look like a granade went off in side the compressor we get 7.5 hour for compressor clutch coil both hoses (high and low) and reciver dryer and a sys flushand recharge
