heater core pipes

Guessing not too many people have replaced their heater core but I'm halfway through the job. Old heater core is out and i'm trying to pull out the aluminum heater core pipes that run from the core to the firewall since the o-rings at the firewall need to be replaced - they're leaking down the firewall.

i've studied real oem and i'm wondering if anybody know if i can remove these pipes from the cabin side? they seem to be stuck and it's hard to tell if i should be able to pull them out.

iirc there should be o-rings on both sides of #22

it does bolt in, but i am not certain if there is a retaining bracket for them or not that is attatched on the inside...

can check and see as i have an entire heater box (almost) out on the parts car.

parts #22 and #11 are on the engine bay side of the firewall, #11 bolts to #22 and #22 is secured to the hvac box via a nut. Was about to unbolt #22 to get to the bottom of this but i need a extra long 10mm socket which i don't happen to have. oh well i have to remove both parts anyway. one of the hose barbs on #11 had broken off. stupid plastic cooling/heating parts grrrr

yeah, the pipes are bolted into the hvac box by a bracket, and the other end by the inlet. there is a long bolt that shouldn't be too tight, so an open end wrench shouldbe able to get it.

i have some pics of what i pulled out today for reference.

^thanks so much for taking the time to take pictures, very considerate of you, i just kept plugging away and figured it out myself in the mean time

found a deep socket (doesn't need to be extra long - just a **** up on my part where i forgot about some more sockets i had) and it turns out to re o-ring the pipes you just need pull off the connection flanges on the engine bay/cowl side and do it from there. There isn't enough room to pull remove the pipes without taking the whole hvac box out, which is another huge job. i thought that i'd need to do so as it as that was the case when i did it on my old e30 a couple years ago.

i got the pipes out with the box still in place, but the dash and column bracket were removed.

and since it's a parts car it's not like i am worried about it going back togethere again...

Old thread, sorry. Are those pipes replaceable without yanking the entire dash?

My heater core isn't leaking, but those pipes are at the firewall
