I totally agree with that super annoying piece. I am always like Ugh! I wish pictures are here in this great thread!

Before you order an evaporator, make sure you check to see which manufacturer you have. I made that mistake, ordered a new evaporator for a Behr box and it didn't fit my Siemens box. I ended up getting a whole box out of the wrecking yard and another evap from a forum member. I used wrecking yard one and kept the forum member on as a spare.

Great information! Do you know where to look for a brand marking on the evaporator box by chance?

You may want to figure it out quickly. Pics are worth a thousand words and help you communicate. Pics may possibly have saved you from some of the mishaps.

Here's the liquid line before I mail it out to be rebuild. I already got most of the gunk out of it last night, but was still able to get a bit more out today. There's a bit of corrosion inside the hose, as well as where the O ring sits. Edit: a bit on where the hose o ring seats as well.
I'm pretty much going to have to re-use this as well as the other metal pieces, such as the metal parts of both suction lines. I wonder if it's worth soaking them in a rust converter then flushing them really well after I cut the rubber hoses off of them?

If you pull it the whole HVAC apart, you'll see a large Siemens casted on the top of the evaporator case.

If you are not pulling it apart, it is harder for the untrained eye by looking at the shape of the box. But you can also tell by pulling and checking the blower, if it's original to the car. The Behr blower will have a caged center on the fan. The Siemens blower fan is solid in the middle.

What kind of flush agent did you use and how did you insure none was left in the system? I have heard some flush agents can cause problems if even a little was left in the system. Not saying that is what happened to you. Just like to know the cause of the R4's demise. How far back did the casing slide back? Do you have a better pic than the one you posted that would show it?

From someone who has never posted a pic as far as I know.

Remember, I have no apps on my smart phone.

Edit... I am sure I posted pics of my homemade / bent ' bent wrenches' for valve adjusting..

So you can't tell unless the blower is the original to the box? If I post a pic of the underside of the box that's in the car, can you tell which box I have?

DeliveryValve 07-26-2016 10:53 AM
Go ahead and post a pic, I'll see if I can identify it.

Here are 2 shots with camera zoomed out all the way, hard to get a wider angle due to space limitation. Let me know if you need other views/ angles.

If you can take a long shot picture of the expansion valve area, that may help more. But looking at current pictures, I would guess to say you have a Behr evaporator.

Is this one better?

I think it's a Behr. One more picture of expansion valve facing the side of the box please.
