A valve that is opened and closed using a solenoid (a cylinder pushing a piston that is electrically or hydraulically powered).
The heater valve is located behind the dash above and to the right of the accelerator pedal. The heater core is right beside it. It is operated by a linkage to the slider on the heater control panel.
Your water shutoff valve is typically located near the main water line where it enters your home. It is often found in the basement, crawl space, utility room, or near the water heater.

Valve shutoff classifications refer to the ability of a valve to completely stop the flow of a fluid. The classifications include "tight shutoff," which means the valve can fully stop the flow, and "loose shutoff," which indicates some minimal leakage may occur even when the valve is closed. Different valve types and designs offer varying levels of shutoff capabilities based on their intended use and operating conditions.
The heater control valve can stick open or closed, as it is operated by an electrical solenoid. Clean old valve, or a new one. Located under bonnet, near bulkhead
