The Mercury Diverter Valve provides smooth power to turbocharged engines by diversion of the excess boost, safeguarding the turbo while retaining the acceleration sharp. Mercury was born in 1938 and gained a reputation of having plush rides, sharp styling and cabins that were such that a normal conversation could be carried on even at highway speed. Its vehicles such as the Cougar and the Grand Marquis had a balanced suspension system and real world value that allowed users to have a comfortable ride without having to empty their wallets. Over the decades, Mercury continued to add user friendly feature, such as refined interiors that absorbed the noise during a road drive to the controls being where a new driver wanted to be. Engines live longer with the aid of the parts inspired by the art of Mercury. Performance fans today are retrofitting the last chapter of the Mercury technology with the intelligent Diverter Valve we were talking about, a small item that diverts pressurized air into the intake as soon as the throttle is closed to avoid compressor surge and reduce the turbo lag. Installation of the Diverter Valve is necessary to park on flat ground and allow the engine to cool down before the installation. Unscrew the battery, and trace the unit on the turbo piping. Get the surrounding intake tubes out of the way, unplug the vacuum line, and unbolt the original Diverter Valve without disturbed the gasket. Install the new part in the same orientation, install the O-ring, and hand tighten the bolts evenly and then snug up. Reassemble hoses and sensors, reconstruct intake path, reconnect battery, start engine, and check for leakages. Boost and surge shall be ensured by a short road test.
