Help your vehicle's vacuum-operated controls respond to engine temperature as designed with the Standard Ignition switch PVS83, a ported vacuum switch built to OEM specification. It is a direct-fit replacement for many Chrysler, Dodge and Plymouth vehicles, including the 1985-1987 Dodge B150, the 1984-1987 Dodge B250 and the 1985-1987 Dodge D100.
A ported vacuum switch uses a thermal element to open, close or redirect vacuum between its ports as engine temperature changes. This switches vacuum-controlled systems in or out at the intended point.
Signs this part may need replacing include a cracked housing, vacuum leaks at the switch, or vacuum-operated controls that don't change over as the engine warms. These symptoms can have other causes, so diagnose the cause before replacing.
See the "Vehicles it fits" section for the full list of applications and engine details.
