Bulkhead
[1] A structural partition that separates compartments. This is generally a metal wall that extends from one side of a vehicle to the other. In the engine compartment, you would find a
radiator bulkhead near the front and a
firewall near the back. Another bulkhead separates the passengers from the
trunk. The dashpanel is also a bulkhead.
