Mono heater valves are for single heater core control. "DUO" heater valves are for cars with 2 controls, like your car. Also the valve IS under the hood beneath the plastic cover that is just behind the left headlight. IF the heater valve is stuck in a partially closed position testing WON'T reveal any problems.
