• Header Tank


    NEW IMPROVED C4 DESIGN!    (From 25 November 2020, baffled sensor feature).

    Here is a header tank designed especially for the stag. This can be easily fitted, and will provide crucial cooling system protection for your stag engine.  This is achieved by some unique and advantageous features:  Watch our VIDEO on YouTube

    1. Low coolant level audible warning system - protects your engine

    2. Top inlet and bottom outlet flow purges all air from the system.

    3. Tops up coolant automatically by gravity.

    4. Coolant flow automatically mixes in antifreeze additive

    The header tank featured here is a custom designed, aluminium alloy tank, and being a horizontal design fits neatly into the spare space on the front left side of the Stag engine bay and also holds more reserve coolant above the system level. Note: The tank design has recently been changed - the large hose outlet is a male AN10 screw fitting, whose position is moved to the end to make more space for a relocated alternator. The black 90 deg hose tail is supplied in the optional fitting kit.

    For your convenience, and simplicity please choose the optional fitting kit if required. This will save you time and ensure that your tank is properly installed and connected to the sytem.

    NOTE: For Mk1 systems (pressure cap on radiator) you need to purchase the 20lb pressure cap.  

    Price: £110.00
