Cold Start Valve
WARNING: This page is about a different car, the 1984 Volvo 760, 1984 Volvo 245, 1984 Volvo 244, and 1984 Volvo 242. However, it is still accessible from the selected car via links, so may be relevant.
The cold start valve is mounted on the intake manifold and sprays fuel during starting. It enriches the mixture so the engine will start easily. The valve is powered through the starter circuit and grounded through the thermo-time switch so it operates for only a short time while the engine is being cranked.
