Not just the coolant. I plugged in about 6 vacuum lines. I also cleaned the gunk from the throttle body plate and cleaned the idle air control valve which both contribute to a smoother feeling engine. But my car doesn’t have a high idle at lights anymore after getting warm. The coolant bypass is a retarded mod. It serves absolutely no good purpose as far as I can tell.
