And I can't even find a radiator cap! Would I be pressurizing through the reservoir??? That doesn't seem right.

But the truck has started throwing codes. Volvo couldn't tell me exactly what it was, but were able to narrow it down to the EGR. So I guess I'll be giving the truck the RAWZE treatment when I get back from Arkansas. Is there a thread with the step-by-step or do I just have to watch the videos over and over until I get it?

If you smell antifreeze with the heater on it is definitely the bunk heater probably one of the o rings. just remove the screw and slide pipes back you will see the o rings will be flat. might as well pull out heater core and check it,if it's leaking it will show on the core they are cheap.
