What all did you do to the A/C to get it working? What were the issues prior?

Since this is a older car and it has been sitting in a garage for the past 9 years. I cleaned all the AC lines, condenser and evaporator. I also checked the condenser and evaporator for leaks. Replaced all the O rings. Installed a rebuilt AC compressor and new Drier and expansion valve. The expansion valves are pretty much always dirty and clogged on old cars (the expansion valve on this Galant was clogged). Vacuumed down the system and checked for leaks. I check for leaks by letting it sit over night under vacuum and see if the pressure holds.
The AC system on these Galant's are really simple and easy to work on. Even the evaporator was pretty easy to get out. I can say that this car is very well engineered, I would compare its design with the 80s model Mercedes. Over built and designed to be easily repaired. /ubbthreads/images/graemlins/worthy.gif

I have driven the car about 200 miles now and I always like to go back and re torque the head studs.(the oil on the valve cover is when I spilt some when topping her off) I also installed the new the hood heat shield.

I need to fix AC on mine. Can you share which drier and expansion valve you went with? Did you convert to r134?
Thanks

Same. I bought a new expansion valve for 1837, just haven't installed it yet.
If Bobby could put up the list of parts he used/ordered, I think that would be helpful.

All the parts for the AC system I got from Rock Auto. The expansion valve and drier are pretty much universal parts for those years and also the O ring kit is universal. And yes I did convert the system to R134. I also downloaded the factory manual which has a very detailed section on the HVAC System on these cars. And always change the Valve Cores.
Parts I used rebuilding AC system
Drier- FOUR SEASONS 33575
Expansion Valve- FOUR SEASONS 39491
O Ring Kit- FOUR SEASONS 26764
AC compressor- click
I did have to put the pulley from my old compressor on to the new one since they where different sizes. The pulley is held on by about 6 little bolts

Waiting for my Wife in the grocery store for about 15 minutes in 98 degree Houston heat with the AC on and the temp stays right in the middle.

If my temp gauge gets anywhere near the location yours is in I start checkin stuff. That is why I have an aftermarket Coolant Temp gauge

Do you run a thermostat???

On every 6G Galant I've had the temp gauge always reads just a fraction under half at operating temp. I believe the gauge is wired that way so the needle doesn't fluctuate so much, and that it gives the illusion that it warms up quick and is stable. Ie, let's say at 190-220F it's going to read the exact same on the stock temp gauge.

My gauge always stays in the middle no matter what temperature it is outside. Also the fan dose not come on until the temp gauge starts moving past the middle. It could be that have the temp senor on the thermostat housing instead of the radiator...

Mine and my two sons are also located on the Thermostat housing. None of ours ever hit the middle until the temps start getting to high. It could be that the needle is a little off on that gauge

Same here, Thom. I set my CEL to come of at 206 through ECMlink instead of having a separate gauge. On really hot days when sitting in traffic is starts to flicker a bit when getting close to that temp. As I get back up to speed and get some air flowing through the radiator it will turn back off. It's worked nicely for me like this for years now.

In also have link set, lol. I take the temp for the gauge from the upper hose. Let's me know if the fans are doing their job

Working on my AC system now. What convert kit did you use? can't find the correct one.

Nice build!So I am starting to see the finish line on this project and pretty excited to drive it.
Today, I replaced the expansion valve on the evaporator and vacuumed down the AC system and checked for leaks. I also installed a aftermarket EVO 3 aluminum radiator, OEM hoses and a Spal Fan. I wanted to upgraded the cooling system because of this SE Texas Heat!
Did you have to remove dash in order to remove evaporator and replace expansion valve?
