Ok, I called the fine folks at Glen Ray. They got me what I needed! The long end pipes are fitted in with o-rings....and the darn thing just pulls right out with some warming and WD 40. Done deal
First pic, this pipes are bolted on. You have the bolts out. And they have o-rings inside where they hat are now rock hard. To remove they pull straight out, but it’s not easy to do. Don’t twist because there are 2 pipes and they can break. Try a heat gun, try to spray some lube in there but not much room for that.
It worked like a charm. I'm pretty sure one of the leaks was coming from this area.....and the others were from the old heater hose fittings. I think the core is good to go. The temp valve is suspect also......
Keeping it rolling in the last day of 2021 how do we get the condenser out? the drain tubes seem to be hanging me up
There is a ferrule over the drain tubes. You have to remove them to pull the evap core out of the case
These A/C boxes area pain, I've done some myself. my two cents of advice is send your heater core and evaporator to Glen-ray for a pressure check and flush after you have them removed from the case.
I'm going to flush and clean them here....and try to perform a pressure test....both static and with temperature. I think RC and team over at Glen Ray are just fantastic.....but its the shipping that scares me. UPS and Fed ex are getting to be just as terrible as USPS and frankly, could care less about your products.
Adding a few pics of the box deconstructed. Take note of the OE insulation and it’s color . A lot of kits out there have great replacement insulation DMT s kit is really good
Nearly done with unit. Pretty unbelievable how gross these things get, and how much documentation you need to do to put it back together
I'll note the DMT kit is very good, and with a few tweeks....will be perfect. I've saved the foam bits and seals from this unit to send them for R&D.
So before I re-install this unit, I'm going to real time test it by hooking up the heater hoses while its sitting on a stand next to the car. I already tested the core ect...but feel its wise to run it up to temperature in a way that I can control and observe. There are a few fairly interesting area's that can leak on these and truth be told.....the o-ring seals on the inlet/exit pipes segment are interesting and the heater valve that's connected via two heater hose segments is also a possible leak spot too. The original speed clamps that I took off are still awesome so I re-used them.. I warmed up the hoses a bit when I installed them to get them to form up a bit. If this all works out well, I'll try to get a lot more pics uploaded for those that want to attempt a A/C heater box rebuild. I really could not find a good vid on YouTube to document this process.....so on my next rebuild I may film it.
