Grand Caravan Condenser R&R

newton5 on Sun July 08, 2012 4:00 PM User is offlineView users profile

Year: 2003
Make: Dodge
Model: Grand Caravan
Engine Size: 3.3L
Refrigerant Type: R134a
Country of Origin: United States


When my brother called about the AC in his 2003 Grand Caravan, I had visions of leaky evaporators in my head.
Turns out the compressor had a major failure internally and is locked up solid. Not good, but I'm thankful to not have to pull the instrument panel.

I'll be doing the whole ball of wax. Compressor, condensor, R/D and both metering blocks along with flushing the lines and evaporators.
I've never done a condenser on one of these, it looks like it comes out from the bottom. I'm wondering if someone can tell me if the condenser will come out by itself, or does the cond. and radiator need to come out as an assembly?

Thanks for any input or tips,
Tom

If it's the one I'm thinking of It comes out the top. You remove the Radiator, Condenser and fans as a unit then seperate them on the bench.

UGHH! Not what I wanted to hear, Chris, but Thank You much for your input.
Baby Brother is going to owe me, big time...

As it turns out, the condenser can be replaced from above. Remove the bumper cover/grille (4 screws and a bunch of push pins), 6 bolts, 2 fittings and you're done.

However, I totally dropped the ball when adding oil back into the system. (I've been distracted lately with some personal issues). I'm still wondering WTH was I thinking?!?!

-I forgot to check for oil in the new compressor (it shipped with 8 oz). I always drain new comps. and go from there. Not this time.
-I added 14 ounces during assembly of the various parts after flushing. (The spec amount for a Dual system).
-I THEN added 14oz AGAIN while charging!! (Realized what I did just about the time the cycle finished).
I've never seen an MVAC system that requires 36oz of oil. Needless to say, it didn't work too well. The compressor was very well lubed, though.

I won't go into the slippery, slimy details of fixing my brain fart, but if I ever see a Chrysler Minivan in my shop again I may need a straight jacket.
