Keep engine vacuum routed where it belongs as the engine warms up with the Standard Ignition Ported Vacuum Switch PVS170. This Ford Ranger switch is a direct-fit replacement for the 1987 Ford Ranger. See the Buyer's Guide tab for engine details.
A ported vacuum switch is a temperature-actuated valve. Its thermal element opens or closes vacuum ports as engine temperature changes, which controls when vacuum reaches the components connected to it. Standard builds this switch with specially designed thermal elements, and it is constructed with brass and a high-temperature plastic housing.
- Quality control throughout: Standard is a global manufacturer of emission components and keeps quality control in place across production, from individual components to the finished switch.
- Brass and high-temperature plastic housing: Carefully constructed to OEM specification for precise fit and performance.
- Specially designed thermal elements: Intended to deliver improved performance.
- Feature-rich design: Built with feature-rich design and componentry.
Signs this part may need replacing include a cracked housing, damaged vacuum ports, a vacuum leak at the switch, or vacuum that does not switch as the engine reaches operating temperature. Other vacuum-system components can cause similar symptoms, so diagnose the cause before replacing.
