@  Fast86GN : (04 March 2019 - 07:05 PM)

I don't think it would that loud probably depends on the mufflers used?

Heater core went in my wife's 2000 GS.  Just bought her a 2016 GS so not in a hurry to repair, but would like to get it fixed so I can drive it from time to time.  

 

I don't have a service manual and other than seeing where the heater hoses go into the firewall have not really looked at it.  For anyone that's done this repair, what's the best way to go about it?   Hoping I can just remove the panels below the dash and get to it from there, would rather not have to remove the entire dash.  Already ordered a Delco replacement core, hoping to work on it sometime in the next few weeks.  Any information appreciated.

if it was only so easy.  step one pull both front seats. then the covers under the dash the console is next,  now you can see the black hvac box, start taking out all the screws iirc theres two layers of crap to remove from the bottom, you need to pull the carpets back to get the rear heat ducts out.  

 

once you get all that crap off and see the core, go under the hood take the hoses off might want to try to blow the core free of coolant if its holding any,  theres a bolts between the two hoses, remove that, cant recall if theres a bolt on the bottom supporting it but look first then wiggle and pull it out,

Wow, the seats and entire console have to come out?  That sounds awful.  I remember hearing the front seats are not bolted down and there is a trick to remove them, is that true?

Nevermind, found info on removing the seats.  This does not sound like a fun job, thought I could get away with just removing panels under the dash but doesn't look like that's the case.

If you need any of those other sections imaged, such as 8C, let me know.

Checked Alldata and adding R&R on the console is 3.2 hours on labor.
So that means it would take me 6
0 to do it. LoL

If you wouldn't mind scanning Section 8C for removing the console I would appreciate it.  Pretty sure I can figure out how it comes out, but with the plastic being old and brittle at this point I'd rather do it properly and not break anything.  Thanks in advance, really appreciate it.

Thank you, appreciate it.  It doesnt mention mention removing the upper dash trim that goes all the way across and covers the radio.  I hate removing that part so hopefully the lower will come out without removing that.   Thanks again.

Got the heater core done today, pretty easy compared to most cars.  Removed the console and the heater core cover was right there, came out in about 15 minutes.  Disconnecting the hoses at the firewall was a pain, but doable.  Didn't start the car or bleed the system yet, just filled it with coolant and will finish another day.  Total time was about an hour and a half.

Thats not to bad, in the event I buy my 4th regal and it has that issue, I at least will know that its not that long of a process, replacing the passenger air bag however... is a pain in the butt!

Yea, it certainly wasn't the most fun repair but really not that bad.  Way better than in my old Fox Body Mustangs, that was a nightmare!   I definitely can imagine the air bag being a huge pain since you'd most likely have to remove the entire dash support panel to get it out.  

 

Got the car all back together Sunday and bled the system, nice hot heat and no more leak.  Interesting note, it's usually a real pain for me to bleed the system but for some reason it was relatively painless this time.  Took much less time than a water pump or even thermostat replacement.  Thinking I just got lucky, but the car started blowing hot as soon as the temp came up and got a steady stream out of the thermostat housing shortly after.
