The filler neck comes off the top of the housing and can be used to relocate the radiator cap to a higher point on the engine itself.
The Filler Neck is also available with standard 1.25" hose or in 12AN and 16AN sizes and was designed for use with an OEM 92-00 Honda Civic radiator cap.
This part will be very helpful on an engine that already has a bad reputation for coolant bleeding.
No instruction included.
