The Coolant Expansion Tank
Fit the tab on the post of the Coolant Expansion Tank Cap into this larger notch of the post on top of the Coolant Expansion Tank Top:
Secure these together from below with one (1) HP screw:
Push this Coolant Expansion Tank Top assembly into the opening of the Coolant Expansion Tank, aligning the tabs and notches, as shown.
One tab of the Coolant Expansion Tank Top is wider than the other, so this will only fit together one way. It is also just a press-fit:
Fit the curved end of the Coolant Hose into the open notch under the Coolant Expansion Tank Cap and push the two pins of the Coolant Hose into the matching holes of the Coolant Expansion Tank, as shown.
There are three holes in the tank for the pins of this Coolant Hose:
First, I pushed the bottom two pins in:
Then, made sure the top curved end was under the Coolant Expansion Tank Cap:
Retrieve your Chassis assembly. Place this Coolant Expansion Tank assembly onto this support flange at the right side of the Chassis, aligning the D-shaped pin on the bottom of the Coolant Expansion Tank to the matching rear hole in the flange, as shown.
The bottom of the Coolant Expansion Tank has this D-shaped pin:
That pin matches the shape of this hole in the Chassis flange:
When you fit the tank, it should look like this:
Secure the tank to the Chassis from below with one (1) KP screw:
