Installation Notes and Tips

Verify the connector shape, terminal count, port size, and mounting hole layout before installation. This valve uses a rectangular connector with 2 male terminals, 2 ports, and no vacuum ports. On some Toyota Land Cruiser applications, the part is located in the engine compartment, so confirm access and hose routing before service. Compare the original valve to Dorman 911-488 to ensure the inlet and port dimensions match the vehicle’s EVAP plumbing.

Quality Assurance

Dorman designs this purge valve as a direct replacement component for the original equipment part and states that it fulfills government emissions requirements for the application.
