The Snap-on 1/2" Drive 6-point 15/16" Particulate Matter Sensor Socket, No. SWR5, allows technicians to access particulate matter/soot sensors found in 2018 to present Freightliner trucks equipped with Detroit Diesel engines. This off-set crowfoot wrench-designed socket, manufactured in Tennessee, provides users with the access and leverage needed to loosen and free sensors frozen in place with corrosion. It also features a clearance slot that allows service without cutting the sensor wire, saving technicians time and effort.
