Review: I just flushed the lines and front Evap Core from a 2010 Dodge Grand Caravan. Fluid cleans well and evaporates fast. Evap Core was plugged, this flush broke through the plug very quickly. I didn't get any residual oily film like other users have reported. It did the job it's designed to do and did it well.
