This was done on a 1991 LS 400. I bought the Dryer/Receiver for $28.90 at Advance auto parts.


First remove the passenger side Headlight.






Now Remove these 3 bolts. (just release the tension on the 3rd bolt on the right for the canister to slide up)


Slide it out like butter.

I have a 95 LS 400. is the AC dryer in the same place ? Thanks. I actualy posted a thread not long ago trying to find this part.

TriniLex

It should be on the left side. I know the SC Lexus its under Driver side Headlight.

GOod luck

Wow, this is fantastic. Thank you so much.

If you don't mind, I have a couple quick questions.

1. After the work you have done, I assume you are going to take the car to a shop and have them evacuate and charge the A/C charge. Is this correct?

2. Aside from the parts you have shown being replaced, are there any other mechanical parts involved in the a/c?

So far I have:
Evaporator
Compressor
Receiver/dryer
Expansion valve

Of course there are the associated lines and motors/servos, but are there any other major mechanical parts I am missing?

Thanks again and I hope you were able to solve your problem!

TriniLex

Thats all you need. You might want to replace all the O rubber rings around all the fittings.

TriniLex

Also yes I am planning on taking the car to get recharged up.

fencera

Awesome. Thanks again for the great tutorials and pictures.

Let us know how it works when you get it recharged!

TriniLex

NO Prob. This is my first time ever atempting this. But it was relatively easy you just need patience.

are there any o-rings on the fittings for the 2 tubes that attach to the dryer?

Heepspo

Why did you replace it?

Was there a detectable problem indicating that it needed replacement?

it's safe to say there is a problem with my dryer. even brake cleaner didnt cut through all the mineral oil that came out of the system. i bought a replacement dryer and ended up snapping the bolt that connects to the dryer-to-condenser tube during installation. i'm waiting for another replacement to continue on the path to climate controlled comfort.

i'm fortunate to have a relative in the hvac business. i already evacuated my system (before trying to replace any parts) and found it was loosing vacuum after a few hours. once i find and fix all of the leak, i'll purge and evacuate a few times, add some more oil and fill with refrigerant.

it doesnt hurt to have access to a quality manifold gauge, 2 stage vacuum pump rated at 5 cfm and 40 microns, and a tank full of r12.

TriniLex

Yes there are 2 which should be replaced. When you buy the dryer it should come with 2 of them.
Thanks

AC was blowing hot. THE evap was leaking.
