Features / advantages

Increased clearance: These replacement housings are close to half the total height of the original and are so slim that they sit level with their mounting studs, also there is a flat step on the top of one side to give extra clearance where it's needed the most on many conversions.

Direct replacement: Our part directly bolts in the place of the original with the same fasteners. The only modification requires is a slight shortening of the oil drain hose with a knife.

Heater option / connection: There is provision for a single port which gives the individual the choice of running with or without a heater. This is placed in the right hand side to face directly where many common models would have their cars current heater hose fit. This allows for the hoses to be near hidden and ran in a very direct path.

Simplification: On the 3SGE Beams engine in it's original form has two heater lines routed over the top of the cylinder head with a metal hose fitting at their ends. When our housing fitted and the original metal coolant line under it is shortened these two hoses and fitting can be completely removed from the top of the head. The throttle coolant feed has also been removed which is redundant for any quad throttle conversion.

Appearance: These may be supplied in a bright billet finish or with a light bronze / gold textured tint.

Supplied components

Each housing is provided with a new replacement gasket and for the buyers choice of heater connection both a 16mm outlet barb and a plug. Many different size barbs are also available on request.


When the heater outlet barb is fitted the OEM water return pipe needs to be shortened, this is located under the housing and originally goes down the side of the engine block and around the back. For cars such as Corollas and Sprinters this is ideally cut just before the bend at the back of the block which lets a hose curve up and hook on to the heater core.
