Yes you can drive it as long as the two heater hoses connect back to one another like you said, and from what I know of this job its a royal pita,but hopefully someone will stop by while you are using the search function and shed some light on that subject,but your fine to drive.

thanks .. i know i couldnt find anything on the search button lol .... umm its driving fine as of now but if im tearing the dash board apart to do it i mind as well rid of the dummy lights as well

Yes you could throw the full set of gauges in it.I think 97 thru 01 will work but again get that verifid cause Im not 100 percent on it.

does this seem to be about the gist of stuff to do for it ?

Just did both heater core and evaporator core in my 2001 about 3 weeks ago. It's really not as bad of a job as it seems. If you give me your e-mail I can send you PDF files of the sections of the manual you need to do the job.

I would recommend replacing the evaporator while you're in there also. They tend to be leak prone and it's right next to the heater core. My evaporator was leaking but I did the heater core also since I was there. I found the evaporator cheapest at NAPA and the heater core was lower priced at O'Reilly. You will need disconnect tools to unhook the A/C lines, I think they are around $20 at NAPA. If you replace the evap, you will need to add the proper oil. If I remember right I think it was 2 oz of PAG oil. The decal under your hood that lists the refrigerant charge has the proper type of oil listed and the HVAC section in the manual lists the amount.

A little tip to keep from making any bigger antifreeze or oil mess inside the Jeep when you remove the heater box. Pump enough grease from your grease gun into the tubes of the cores to seal the liquid in, then push it a bit with a wad of paper towel to keep the grease in. DON'T do this if you plan to reuse either core, you'll never get all the grease out.

If you want the PDF's sent let me know before about 3pm today. I'm working out of town this week and I don't know if the campground I'll be at has internet available.
