TracTuff K24Z Rear Wheel Drive K Swap Filler Neck – Ex Side Outlet

Description

The K24Z filler neck for exhaust side outlet hose routing is the smartest way to add a filler to the highest point in the cooling system.

If you haven’t already read the product description of the K24Z Water Neck Flange and would like to know how it came to be and what makes it special, please take a moment to read its product description.

A 90° filler tube is added to the unused -16 ORB port opposite the outlet, eliminating the need for a -16 ORB plug, and adding a convenient way to burp the cooling system. Just choose the type of connection you would like to make at the remaining -16 ORB port and whether or not you would like a heater core nipple added. An ECT sensor port is included, but it has been moved from the OEM location. The hardware kit includes four M8 socket head bolts, your choice of 1.25″ hose barb or -16 male flare port fitting, and two OEM o-rings.

NOTE: The cap bung features a 1/16″ NPT port for connection to an overflow and is compatible with early model Honda radiator caps, such as those used on 88′-91′ Civic/CRX or 90′-93′ Integra models. A minimum of 1.99″ of space is required between the firewall and the water neck mounting surface to accommodate this setup.

Also, if you choose to have a heater port added, it will be placed on the filler neck side and in the bend at approximately 45°. I recommend a -10 to push-lock style fitting (shown below) to make the necessary change in direction.
