The cowl is the part of a car body between the engine compartment and the dash face. The cowl includes the firewall, cowl top panel, and upper & lower dash panels -- but not the dash itself. For the Datsun 1200, the cowl is where fresh air for ventilation is drawn.

Firewall & Dash
The steering post bracket bolts to the firewall.
These parts make up the Cowl:
- Cowl Top
- Dash-Upper
- Dash-Lower
- Dash-Side
The dash-side has openings for the optional speaker and the upper and lower door hinges
View from engine compartment:
View from inside cabin:
The water box is also known as the ventilation plenum -- it is where air enters the cabin. The large oval hole in the center is for the heater (or ventilator). The cowl vents are located at the base of the windshield due to aerodynamic reasons.
Cabin air Inlet
Normally, rainwater goes in through the top through the Cowl vents and falls onto the topside of the Upper Dash panel. From there it runs out a vent hole on the outside of the panel near the guards (fenders).
Lower Dash panel:
In this photo, the Reinforcement has been removed, and you can see how the hoodledge joins with the firewall and radiator panel to form the engine compartment:
How the hoodledge (inner fender) ties in to the A-pillar:
The dash unit mounts via three brackets welded to the firewall
Insulation
- Low-density Fibreboard (LDF) insulation is used on the inside of the firewall.
- Medium-density fibreboard is used on the Kick Panel

Repairing Water Box
Water comes in though the vents behind the bonnet, then runs down to a hole that is there to let it out. If this is rusted, it will instead leak down onto the fenders.
