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. Two versions are available, one has a 1.5" barb fitting that accepts a factory size inlet hose and the other 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.
