FIGURE 15 NYLON TANK VACUUM BRAZED ALUMINUM RADIATOR - F SERIES & BRONCO WITH GASOLINE ENGINE
The crossflow fin and tube design radiator used on F Series and Bronco vehicles with a gasoline engine is constructed with a vacuum brazed aluminum
core and nylon end tanks (Figure 15). The nylon end tanks are attached to the aluminum core by bending tabs on the core header over the edge of the
nylon tank. An O-ring gasket is placed between the nylon tank and the radiator core header to achieve a seal between the tank and the header. The nylon
tanks are a molded one-piece design with the mounting brackets part of each tank.

REMOVAL AND INSTALLATION
Radiator Tank - Removal
The radiator tanks are molded, glass-filled nylon and are attached to the core header by bending the header tabs (Figure 16) over the edge of the tank.
When removing a nylon tank, a screwdriver or one of the various special tools available can be used to open the header tabs. Some of these tools,
including a screwdriver, may cause a small section of the header side to bend with the tabs as they are opened. This slight deformation is permissible,
provided the tabs are opened only enough for tank removal. The header sides will usually return to the normal position when the tabs are crimped during
tank installation.
Procedures are given for tank removal using a screwdriver or a Burroughs Tool BT-8260. Follow the manufacturer's instructions for other radiator tab
opening and closing tools.
