Outlet choice

This housing has provision for a water feed on either or both sides. For those who have a vehicle such as an AE86, AE71 or KE70 then the original right hand outlet direct (towards inlet) is correct as it needs to be directed towards the heater flow control tap. But for the earlier Corollas and Celicas without the tap a left hand is required instead. A second choice is a non heater option in which both holes have a plug in them. Many custom options are also available on request, such different heater outlet sizes or a combination of a heater outlet on one side and a turbo water feed on the other.

Each housing is also supplied with a barb and two plugs to either block off the outlets for no heater option or alternatively use the barb to connect a 16mm (I.D) heater hose. Other options on request.

There is no provision for the throttle coolant line supply however a T-piece could be used for it’s connection if required.

 

Sensor provision

On the top of this housing are two threaded ports which suit the same sensors as per the OEM part this replaces. These are for the ECU water temperature sensor and the injector cold start sensor switch.
