When changing out the AC evaporator is it necessary to change out the above.

The receiver/dryer is considered a disposible item. Anytime the A/C system is serviced, it's recommended it be replaced. In fact, most recommend it be changed out every 3 years for maximum efficiency of the system...but who the hell does that?

The dryer is like a sponge designed to soak up moisture in the system. Any moisture in an A/C system is death to the system, so that's why this part is so critical. Over time, moisture naturally finds it way in so this part begins to become saturated. If the system is open to atmosphere, it begins to soak in moisture like a sponge. When installing a new one, it's typically done as the final step and then left capped for as long as possible before connecting. Then, a GOOD vacuum should be pulled for 1 hour minimum.

In the past, i've gotten away with NOT replacing it by pulling a good vacuum for 24 hours or more. I just hook up my vacuum pump and walk away for a day. Water in a vacuum will boil off, but it takes time to make sure it's all evacuated properly. I usualy try to save the drier on friends cheap *** cars, or if i'm trying to do a cheap repair.

On an decent car, or a repair where you already have several hundred dollars invested, i wouldn't skip out on it.


Is a shop recommending it be replaces as a repair done to a leaky evap core?? If so...it's not BS, they are doing it right.

 

Not sure this helps, but when I replaced my AC compressor/clutch with one from RockAuto, it was required to replace the receiver/dryer at the same time for warranty purposes.

Thanks guys, I ordered an after market one, better safe than sorry. The evaporator has to be changed. Seems to me I read the whole dash comes out and even maybe the front seats..Sounds like a huge job for the home handy man..

Hey there

I realize this post is really old but I'm hoping someone is able to see my response and help me out.

This will sound like a total newbie question but can anyone give me the location of the Receiver/dryer on my '06 Coupe? I have to replace the high pressure line and the receiver due to the aftermarket intake rubbing through the line.. sigh..

Problem is.. I've never done this work before and have no idea where the receiver is located. I'm going to have a shop do the evac on the system and then recharge it myself to save some coin.

Any help would be greatly appreciated!! There are no dumb questions right!!?

Thanks
Ty

 

Service manuals for '06 coupe here:
http://www.nicoclub.com/FSM/G35/Coupe/2006_G35_Coupe/
"atc" is the AC section.

 

Right thank you! I have this already but I don't see where it refers to the replacement of the receiver.. that's why I posted the question.. Maybe I'm just looking in the wrong place in the document. It's about 160 pages long..

Thanks again!

 

Maybe it's called something else in the manual? I've seen it called accumulator, receiver, drier... so I'm not sure..

 

I think receiver drier is in the engine bay around the front of the car like behind the grille but double check. Attached is PDF for ac lines and receiver drier.

Thank you!! Yes I saw that part you circled and was just looking at it on my car thinking that it must be it. It's a lot larger than I was expecting actually so was looking for something small back by the firewall.

I really appreciate the help

Cheers

Correct, the circled part is the receiver drier.

Make sure after you replace it you have a shop pull a high vacuum on the system if you don't have the means to yourself

 

Thanks again for the help guys. I unfortunately don't have a compressor suited to evac the system properly so I'm going to have a shop do that and then recharge the system on my own.

Anything special I need to consider when I replace the receiver drier?

 

Don't do it on a humid day, and try to keep the new one exposed to atmosphere as short of a time as possible.

 

Without a micron gauge, you can never pull a vacuum too long. I would suggest 1 hour minimum with a 6-8 cfm vac pump.
