Custom water neck fitting for Ecotec style engines (2.0L, 2.2L, and 2.4L). This water neck is CNC machined from a solid block of 6061-T6 aircraft grade billet aluminum. It bolts in place of the factory angled unit and deletes the heater core and recirculating lines. The inlet type is a -16AN fitting that accepts -16 after market hose.
Our block is already drilled and tapped to accept an 1/8" sender and also the factory coolant temp sensor. It also utilities the factory seal for the outlet hose and heater line block. This unit is designed for off-road use only and does not accept a thermostat.
Coolant temp sensor sold separately.
