Before he designed theP38 heater core location, with particular attention to the accessibility to said units “O” rings, he worked at Chrysler.
Try and understand his last video presentation before departing for Solihull, UK.....
As Spock would say... “facinating”

Interesting video: I think I saw this chap once in a Vauxhall stealership explaining to a lady 'just' why her 'standard' service was £800+.....

Nice to know that sometimes they can get it right though; https://mars.nasa.gov/raw_images/13/?site=insight

As Kirk (or possibly Matt Damon) might say; "Let's strip it for parts and build a better P38 BECM...."

The O-rings are easy, you can do them in about 45 minutes. If you've got a left-hand drive version it ought to be even easier, since the pedals aren't in the way.

Heater cores are always buried in the dash and dashboards are always tedious to remove :(
When I rule the world, all cars will have maintenance hatches for any component that isn't guaranteed for the life of the owner!

Tell that to Renault! I've spent this weekend underneath an Espace to get to the heater fan, as they have located the fan, heater core and resistor pack under the drivers seat with access from below.

Probably preferable to removing the dash though.

Remember they have to start somewhere. Of the many cars I've owned in the past on one they started with the handbrake cable and assembled everything else around that and on the other they started with a wiper motor. There is always going to something that was fitted into the shell before everything else went in making it an absolute bastard to get to.

I can recall someone I knew with a broken clutch cable on a Citron Xantia being quoted 7 hours to replace it - Due to a lack of space around it where it came through the bulkhead you had to move the engine to allow access. The 7 hours being for the RHD version and Citroen's own times for the job, LHD was 45 minutes!. All due to a broken plastic fitting on the end of it.

7hrs or 45 minutes, sounds like the rear rh exhaust manifold bolt on a p38, lol.

I remember the first set of heads I did on one of mine, I was determined to get all the heat shield bolts, took 2 days, not any more, 20 minutes both sides

I wish I could have gotten mine off in 20 minutes! Didn't quite take me 2 days but it still took longer than I would have liked.

If they ever have to come off again it should be nice and easy. After hammering and shaping the shields back in to an acceptable shape new holes were drilled in them and some stainless steel rivnuts and stainless steel bolts were fitted.

I do need to replace the bonnet release cable as the plastic handle/lever in the cabin snapped at the weekend. I hope it's not as difficult as the Citroen clutch cable!

In reality, the heat shields only need the 2 bolts on the brass studs, they don’t rattle, and heat is deflected away from the ht leads, I looked at redoing with rivnuts, but never got round to it, ..

Heater core on a series Landrover is just a bit easier to access...
Last heater matrix I did was on a Zafira, relatively easy but still not piece of piss, never any fun working on stuff buried under dashboards. I ran Chrysler Grand Voyagers for years, matrix access on the early ones was a dash out job but on post 2000 models can be easily accessed from passenger footwell. I think it was the same story with heater resistor packs (well, transistor drive pack on post 2000 ones) and same with blend motors (which I've done on later ones).
