Description Aussiespeed  Holden 6 cylinder red motor cast aluminium thermostat housing base.  These are a hand made sand cast housing not a diecast machine made housing that is CNC machined not linished on a belt. It is recommended that a corrosion inhibitor be used in the cooling system. They will bolt to red motor, blue motor and black motor cylinder heads that are not using the factory water hoses for manifold heating or need to run water outlets without adding extra fittings.   The base is 10mm thicker on the head face so a thermostat housing base spacer is not required when fitting an Aussiespeed rocker cover.It is supplied without bolts and gasket, AS0602R-K includes additional gaskets and hardware and is available in our online store. These can be used to replace WOB77 Kilkenny Castings part number . Aussiespeed offer both top and bottom housings and can be purchased as kit including gaskets and bolts in our online store. Add a custom touch by painting the thermostat housing a color to match your engine or engine bay.
