| Description: | Electric Water Valve Assembly | Model: | Titan, Armada, and Quest |
| OEM: | Nissan | Model Year: | 2005 |
| System Supplier: | Cooper-Standard Automotive | Generic Resin Type: | PPA |
| Molder/Processor: | Klum | Resin Trade Name: | Zytel |
| Toolmaker: | Klum | Grade: | HTN 51G35 HSLR |
| Material Supplier: | DuPont Automotive | Other Innovative Features: | The valve incorporates an integrated plastic bracket and features Cooper-Standard's innovative over molded hose connection technology. Light weight construction, dual functions, and accurate control. The valve drives with a polarity controlled voltage at a low amperage provided by the Engine Control Unit. |
| Most Innovative Feature: | First single package, multi-function underhood water valve assembly to use overmolded joints assembly module to delivery better heat/AC performance with lower cost and weight. | Forming Process: | Injection molding, overmolding, heat staking, thermo riveting, and ultrasonic welding |
| Weight Savings: | 40% savings | First Time Process Used? | No |
| Cost Savings: | 15% savings | Previous Process: | Previously, the valve was manufactured out of metal that increased its weight. Constant tension clamps were required at all hose connections contributing to a higher overall cost. |
| Cost Avoidance: | 95% less current draw allows removal of vehicle control relay. | Transferable to Other Vehicles: | Yes, This product is designed to perform to global customer specifications. |
| Benefits to Consumer: | |||
| Yes, the consumer is able to obtain a vehicle that performs better overall due to improved AC and heater performance. Additional efficiencies are achieved through weight reduction impacting fuel economy. | |||
