LS Conversion Thermostat Housing

The first OEM-style thermostat housing for LS swapped muscle cars and trucks! This 6061 die-cast aluminum housing is a direct bolt-on for LS1, LS2, and LS3 engines and points the water inlet toward the lower radiator hose connection. This routes the lower radiator hose away from frame rails, around belt drive systems and eliminates the need to run an excessively long radiator hose! Made with die cast 6061 aluminum, heat treated and CNC machined to index the housing for the original style LS thermostat. Made in the USA.
