A/C Evaporator Core - Replacement

[Mopar1973Man]

Ok Gang... I just got my replacement evaporator core from the local NAPA store. (Lifetime warranty - No cost) So when I go to pull the dash out I'm going to grab the video camera and record out the whole affair. Show you that pulling the dash is really easy on a Dodge Ram!

Yes I did last year at this same time... But the core has failed... It's leaking... I pressureized the system with compressed air and ran the A/C to move the dye around. Then shut it all down and watch with a black light in a dark shop and never found any green dye in the engine bay area. So this means the evaporator is leaking again... I even pulled a vacuum back on it and checked and it loses 5 in/mg in about 10 minutes time. So it a good sized leak... So now that I got the new core I'll grab the video camera and record the re-do of this... And you guys will find out its easy as pie to do... (Serously!)

CoolHoe that's not what's wrong with mine as it was Midas in Missouri that did the work Good to see video especially which bolts and clips to get it out ;)

Video is done...

It's 350 MB long and will take me a bit of time tonight to upload to YouTube. Now the video is from the re-assembly process so I'm sure you guys and gals could see how it comes apart and goes back together. So the video start from the point of the new evaporator core was installed in the HVAC box and re-assembly from that point to done...

So hopefully I remember to upload the file before I head to bed.

So was the evaporator toast ??? Is there a pic or schematic that shows the evaporator and heater core together ? thx for the video

[Mopar1973Man]

Well as for the evaporator both of then shown no sign of dye on the outside.

Notes

Remember the UV dye only last a few hours after being exposed to air. The green will dissappear in about 4 hours after leaking out of the system.

I remember you saying that (the dye) ..... so I rubbed some of mine on my battery cover ..... and its still visable after 2 weeks ...... must have the "aussie strength" - hahaha *joke* Yeah thanks for the pics - I remember that now from the 1st time - So the blower is actually closest to the evaporator - I would have thought it blows directly over the heater core - but guess its more elaborate than that. So is it holding a vacuum now all said and done ??

[Mopar1973Man]

Haven't bother to put a vacuum on it yet...

Thanks VERY much for this video Mike! :thumb1:I've got a blend door issue that I'll probably need to access the top of the box to deal with, if not remove the box, so it's very good news to see it's really not a 37 hour job entailing complete dash and cluster removal. My only pain point will be that I didn't make my shifter stick removable, I've got to pull my cover plate and pull it off the trans. Maybe a good excuse to fix that. Anyway, thanks again!
