What It Helps Address

Installation Notes and Tips

Confirm hose diameter and port count before installation. Match the existing vacuum hose routing to the original layout, and inspect nearby hoses for cracking, soft spots, or oil contamination before installing the new valve. For fitment verification, use the vehicle application list and compare the original part number to DV158.
