Wow thanks a bunch Phil!  Now I know enough to be dangerous.  Good pointers on 
maintenance intervals.  
Best regards

Open the frunk, you'll clearly see a big plastic panel between the windshield 
and frunk "tub".  This will just unsnap, so grab a side and yank upwards.

Here's what it looks like with all the plastic removed, including the frunk tub:

Upper right you can see the brake master cylinder (DOT4).  Middle right, the 
12v AGM battery, Middle left, is the "superbottle" that holds all the glycol 
(G48 coolant ONLY).  Lower left is the "super manifold" for the heat pump that 
has the Liquid-cooled condenser, the receiver/dryer, the chiller, and all the 
expansion valves and "octavalve" and pumps for the glycol.  To the lower right 
is the HVAC compressor.  (newer ones like yours will have a black foam covering 
for NVH.  Far upper left you can see the 2 glycol lines for cooling the ICE 
(Car/Autopilot computer) that's on the other side of the firewall, and upper 
middle are the 5 R1234yf refrigerant lines that run into the cabin for HVAC.  
In between this and the 2 glycol lines for the ICE is the air intake plenum.  
Normally there is a big duct here that sucks air from the windshield base 
plenum.

The only thing you should ever need to do under here is replace the 12v battery 
or the DOT4 brake fluid.  I recommend every 2 years in a humid/coastal climate, 
or every 5 years otherwise.   Brake fluid is highly hygroscopic.   Expect 2-7 
years for the 12v battery depending on climate and usage.

The G48 glycol coolant (blue stuff) never needs replacement.

I'd replace the drive unit lubricant every 5 years if I was planning on keeping 
it forever.  (You should probably let Tesla do this, mainly as it's unobtanium.)
