Description
The Bowman FH420-2938 engine mounted header tank is suitable for Ford 6 cylinder 250 BHP newer engines, such as the Ford 2704 ET engine. The header tank features an aluminium LM6M body, a cupro nickel tubestack and naval brass end covers with 32mm raw water input and output connections. The Bowman header tank measures 574mm long and has M8 x 12 fixing holes. This FH420-2938 header tank will replace the Bowman FH420-2928 header tank.
Bowman recommend NOT fitting zinc anodes because the tubes used in the construction of the heat exchangers are copper-nickel alloy, and as such they do not require a zinc anode. It is possible that if a zinc anode is fitted it can actually destroy the copper-oxide film built up by the tube as a natural defence, which can allow the tube material to be attacked.
