Ok have you used it in a car like mine?

 

I used 8 oz mineral oil in a 90 EX I owned and used R12 to recharge.

I used 8oz ester oil in my 94EX to repair. The 94 is still cooling well 8 yrs later. I had to add a small amount of R134a this year.

good luck

 

can you give a brief write up on how you removed the evaporator to clean it?

I am getting ready to overhaul my A/C system next week and would like to be as complete as I can.

 

Removing evaporator:
1) Discharge system
2) Disconnect high/low connections on engine side of firewall
3) Remove glove box and glove box frame.
4) Disconnect ac thermostat
5) Removing retaining bolts/nuts on evaporator box (7)

Once box is removed, open box to access expansion valve and evaporator.

Avoid getting PAG oil on styrofoam evap shroud, it will melt the foam.

Process is well described and illustrated in shop manual.

good luck

What if all I want to do is clean any leaves . junk in there?
Could I just remove glove box and the 7 screws and get the hose to a shop vac up there?

 

I don't think you would be able to clean it in the car, but I may be wrong. Mine had a lot of leaves and acorns. On the left side of the evaporator box there is a gap so maybe you could fit a adapter to your shop van and clean most of it.

If your system doesn't work it only takes about 20 minutes to remove, at least it did for me. I spent more time detailing it then removing and installing.

Hope that helps.

 

You will not be able to remove the plastic casting to access the evaporator core without removing the whole unit from under the dash. There are some screws holding the two half together and some clips.

It really isn't much work to remove the 5/7 nuts that hold it in place.

 

ok sounds like I am going to remove it all, I will post up my results next week.

 

Remove the evaporator box. It's not that hard. You may find the evaporator has leaks.

good luck

 

Heres what my manual says:



When it says per line, how many lines are there, I counted something like 8 or 9 so if that is then it is 8oz or so
