Thermostat Housings & Water Necks

Thermostat housings and water necks for Holden 6 cylinder and V8, Ford Windsor and Chevy SBC and BBC engines, mostly in polished chrome die-cast finishes. Options include straight, 45 degree and swivel outlets, twin outlet designs, and kits with gaskets, O-rings or thermostats included. Confirm engine variant and year range, outlet angle and seal type before ordering.

To pick the right housing, confirm three things: the engine variant and year range, the outlet angle, and the seal type. Holden sixes and V8s, Ford Windsors and Chevy small and big blocks each use different bolt patterns, and Ford Windsor housings changed between the 1962-1978 and 1979-2002 ranges. Outlet angle matters for hose routing: straight, 45 degree, 90 degree and swivel designs each suit different radiator positions, and twin outlet housings carry heater or bypass connections. Some housings seal with a paper gasket, others with an O-ring, and several kits include the gasket, bolts or a thermostat, so check what is in the box before adding extras.
