[dodgenfox]

Had mine done at the dealer but I also wanted the dash replaced. Took a big chunk out of my wallet though. Good post.

Thank god I found this post. My heater core just went out and it is not covered by my warranty. The service guy called and told me this today. So my first question was "Okay, how much to get it replaced then?" he responds with "Are you sitting down?" and pauses,I think OH SH** and then reply "Yea I am" then he came back with "$982 plus tax" I laugh and say "Kiss my a**, I will be there in a minute to pick it up. I will just check the Dodge board and do it myself."

Can anyone posts the pics that are now missing from earlier in the post??

It my turn to replace my evap

[krs7272]

Just did mine on my 2001 yesterday took about 4 hrs. Not to bad at all if your mechanically inclined.

Now question I have I replaced my evap and accumulator also. And decided and bought a recharge kit that came with 2 18oz cans of refrigerant. I added one can and per the instructions set the gauge that is inline with the can to the low pressure side to the chart ambient outside temp and filled until the gauge read 40psi concurrent with what the instructions said. Drove around today and is blowing about 45-50 degrees out of the vent.

The under hood tag states 1.875 of freon is needed. But I have only 18oz in currently and want to know should I add more as I don't have 1.875 in there? I don't wantto overfill but need some clarification before I add any more?

Thanks

What tool did you use to seperate the lines?

I followed these instructions yesterday and I found only one step missing and I took some pics. I however forgot to get a pic of the unit out of the truck. Some pics aren't here, if you need pictures for the steps that don't have them, you should be taking this to the mechanic.....I forgot to circle things in the pics, I will throw down with some MSPAINT soon to have the parts stand out.

1) Disconnect battery cable

2) Remove first screw on door sill both sides (these are the pieces that hold your carpet down)

3) Remove kick panels and panel under steering wheel.

4) Remove two nuts holding up steering wheel.



5) Remove five screws where dash meets the windshield.

6) Remove 2 bolts on the left and right side of the dash up against the side of truck (under kick panels)





7)Dashboard can now be pulled free toward seat.

8)On passenger side of dash tie rope or wire to flange where bolt went into side of truck and lift dash up to expose fan box. Secure rope to handle on side of A-post



9) Remove vacuum lines and unclip electrical connections. (Hint: temperature control cable has to be removed with pliers by pulling straight up, removing the entire clip.)



10) Now the secret: there are two screws holding the box to the firewall on the inside (one has ground wire attached.) The other is in the upper right hand corner facing up.




11)There are four nuts holding it from the engine side of the firewall (one nut is accessed by removing the electrical panel on passenger side.) Remove all four nuts.

12)Remove heater hoses by removing clamps. Mine were stuck so I just cut the hoses and got new ones.

13)Release A/C freon from LP side with gages and disconnect A/C lines from firewall exit. ( This requires a simple 5 dollar tool that disconnects fueland A/C connections.



14) The heater box will now come free!

15) There are several screws holding heater box together. It will come apart in two halves. Go ahead
and replace your heater core because you dont want to do this again in a month!

16)You may want to replace your accumulator as well (its fairly cheap)

17) Reassemble /reinstall box. Draw vacuum on A/C system for 30 mins. recharge with 134a.

Just wanted to say thanks to everyone!!!

I would have been lost without the pictures... seriously....

It took me about 6 hours with air tools, my laptopon the work benchand a hangover.

I still have to charge the system and replace the two heater hoses (I had to slice them off).

This post was one of the most helpful to me on this site!!!

I think the only thing missing here is the fact that the cable for the shifter should also be removed.You know the one for P R N D 2 1
