As surprising as it may seem, my local dealer does not have a flow diagram, and the parts diagram is useless.
As you have confirmed, its quite complicated under there. In addition to the (3) radiators with their hoses & metal lines that run from back to front and return, the heating system also makes its own run up to the front and back again. Plus there is a bypass circuit that runs over to the Coolant Expansion tank on the Rear Left corner.
I am converting a 911 SC chassis to take a water cooled 996 motor. I want to make sure I have all the essential lines and eliminate any that are not needed.
For the heater, I want to tap off the main coolant lines up front, like the V8 conversion guys do.
It looks like I wiil have to buy a $1200 Renegade Hybrids radiator system for the car, but I want to learn as much as possible about the 996 design before I make that decision. I really want to keep it as much a P car as possible.
Thanks in advance for any and all help w this.
