The Aeroflow Performance remote thermostat housing allows you to remote mount a thermostat in the cooling system away from the engine itself. This is useful for cars that have no room to allow the thermostat to be on the engine itself such as a blower manifold. This remote thermostat housing also allows you to locate the filler neck at the highest point of car with low mount radiators to help bleed air out of the system. It is designed to adapt a Chevy thermostat housing along with a Chevy thermostat. Made from billet aluminium with two female -12 ORB ports on both sides and 3/8 UNC mounting holes. Comes in three colour options blue, black & silver.
