You DO have a sandwiched cooling system.
Let's start at the "front": engine, fan and fan shroud, CAC (Charge Air Cooler), radiator, back grill.
And the air flows in just that way front to back.
You have to clean it from the front, since the front of the CAC is the "filter" that catches the vast majority of the debris.
You have to access it from the bedroom or closet-- you need access to the front of the fan housing, as you will be spraying soap and water in the front of the fan shroud/between fan blades.
To check on the condition of the front of the CAC, use a strong flashlight (best after dark). Shine it from the bedroom/closet into the front of the fan shroud. Verify that the perimeter, particularly lower perimeter is as clean as the center (the fan blades sling the dirt to the perimeter).
Also make sure that your crankcase breather hose has been extended to behind the fan shroud. Will cost about $10 in "parts" if you want to do this yourself.
I would NOT recommend the use of high pressure on the front of the CAC or radiator-- way too easy to bend fins.
