AC delete with engine in car How hard would it be to remove the hvac box with the engine in the car? I am going to keep heat when I do this, so pulling the dash and pulling it out from the inside is not an option. Is it possible to use a cut off wheel, dremel, and or hammer and just break the box out of the bay, while keeping the stuff inside the car intact?

You must remove the dash to remove the hvac the correct way. The heater core is connected to the hvac so a hammer or cut off wheel will o my get you so far. It takes less that. 10 min to remove he dash anyway.

I just did mine with engine in the bay, it can be done. If it is only 10 minutes to remove the dash, you'd be quicker going that route than the way I did it from the engine bay with engine in. 1 hour and 15 minutes for me, so far. I am just about done maybe 10 more minutes of fine detailing.

Air ratchet and knowing where the bolts are. 7mm for the top 10mmor for the console and 13mm for the end bolts and 15mm for the column. I use the seats to rest the dash at an angle to pop the evap box out. Once the dash is out I use a 10mm swivel to remove eval box with a 12in retention.

Well I took the plunge today and did some more cutting on the car. The AC delete turned out good, my heater blows just as hard as factory. The cutting isn't too bad, just tedious, and all that fiberglass dust from the lower portion sucks!!
Now I just need to relocate the alternator and get rid of the ABS block, then hide all the wires with the next build.
I also kept the vacuum line so I can still switch the airflow to head, feet, or defrost.
After all the cutting
With the panel to re-route airflow in place
All finished up

Is there a pully to put in place of the one that was there for the compressor?
I took out the compressor of my sons camaro but unsure of how to run the belt now.

Im about to do this since the engine is out so the cutting shouldnt be to bad. If I make the passage to retain heat can I use the UMI delete panel on the engine bay side? Ive read its made for the inside of the car.
My other question is how did you attach the panel

I just did the AC delete on my car. I kept the heat and installed the UMI delete panel from the engine side of the firewall. Check out my thread on LTxtech, I used the pictures Spartan7 posted on where to cut the inside of the old HVAC box to keep the heat functional.

The UMI panel is made to be installed from the inside of the car. I had to trim one corner a little to make it fit on the engine side of the firewall. I used all the same bolts I removed from the HVAC box. There were a few holes that I had to get creative with and used some fasteners from the local hardware store. I cut an oval hole for both the heater core lines to pass through. Behind them I used some HVAC foam from the hardware store to make a gasket with plenty of RTV to seal everything up air tight.
