L-shaped by pass hose from top center front of the engine attaches to a metal tube along the passenger side of the engine. It then connects to a pass through sensor/valve. Mine had the plastic hose nipple broke off and needs replaced. It looks like it has a wire rather than vacuum but I will be digging into it tonight. Truck does have electronic temperature control (AC/Heat).
What is that sensor/valve called so I can order a new one.
