- Remove the mounting hardware and lift out the old reservoir.
- Compare the notched side with the cruise-control module location.
- Transfer serviceable pump and sealing components as required and install the selected cap.
- Refill the system, operate the washer and check every connection for leaks.
Is this reservoir limited to TPI engines?
The current official product page lists the part by Firebird year and tank configuration rather than limiting it to TPI only. Verify the notched reservoir shape and engine-compartment layout.
Why is one side of the tank notched?
The notch provides clearance for the Firebird-specific cruise-control module location.
What is the factory-correct year range?
The current listing identifies 1985-1988 as the correct OEM-style application.
Can it be used in a later Firebird?
The product page states it can fit 1985-1992 Firebird models, but it is the correct style for 1985-1988.
What causes washer tanks to fail?
Age, heat, chemical exposure, impact and overtightened mounting points can crack or discolor the molded plastic.
