Standard Ignition DV87 Diverter Valve

Standard Ignition DV87 Diverter Valve

Standard Ignition DV87 is a vacuum system diverter valve for emission control service on select Cadillac applications. It is built with high-grade materials and tested at the end of the production line to help maintain consistent performance and fitment.

• Emission control diverter valve for vacuum system repair
• 1 connector with pin terminal type
• 3 hose connections for 1/4", 5/8", and 3/4" hose sizes
• Hose sizes listed in both inches and metric: 7 mm, 16 mm, and 18 mm
• Standard Ignition DV87 for direct replacement service

Fitment and Application

Compatible with 1987-1990 Cadillac Brougham and 1986 Cadillac Fleetwood. This Standard Ignition DV87 diverter valve is a fitment-based solution for Cadillac Brougham and Cadillac Fleetwood vacuum system repair where the original emission control valve has failed.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Fix

• Vacuum leaks caused by a worn diverter valve
• Emission control system faults related to vacuum routing
• Rough idle or drivability issues tied to vacuum loss
• Failed valve operation in the Cadillac Brougham or Cadillac Fleetwood vacuum system
• Incorrect air management in the emission control circuit

Installation Notes

Verify hose diameter and connector style before installation. Match the pin terminal connection and confirm the hose routing against the vehicle’s original vacuum layout. For 1987-1990 Cadillac Brougham and 1986 Cadillac Fleetwood applications, inspect adjacent vacuum lines and fittings for cracks or hardening before replacing the valve.

Quality Assurance

Standard Ignition states that each DV87 diverter valve is end-of-line tested and manufactured with high-grade materials. As a global emission components manufacturer, Standard Ignition maintains quality control through the production process from component parts to finished valve.
