Bonbo Professional Diesel Injector-Seat Cleaning Kit 8090S on Cylinder Heads, Including Helix Brushes, Two-Stage Brushes, Bore Brushes and Swabs (Stainless Steel, 17-Pack)

When removing fuel injectors from a high-mileage engine, do you consider the possibility of built-up debris such as rust and carbon being lodged in the injector seats? We certainly hope you do, because that residue can prevent a new injector from installing and sealing properly, and thus cause a leak. An improper seal may also allow gases, fuel, and compression to pass around the injector, creating a loss of power. So, each part of the injector seat should be cleaned whenever an injector is removed or replaced. Removing dirt and debris from injector seats is exactly what 8090S Professional Diesel Injector-Seat Cleaning Kit does. The kit features three types of brushes: Helix Brushes, Two-Stage Brushes and Bore Brushes. Each brush type is designed for cleaning specific areas of an injector seat. A driver handle with a quick-lock coupler and two extensions is also included, as is an assortment of swabs. These brushes and swabs vary in size and can be used for multiple and different applications. Helix Brushes: (1.375", 1.1875", 1.160" and 0.990") Used to easily clean the deep-seat bore. Simply inserts the Helix Brush into the injector-seat bore and turning its handle clockwise. Two-Stage Brushes: (1", 0.750" and 0.500") Used to easily clean the seat and inner-seat hole. Simply inserts the Two-Stage Brush into the injector bore and turning its handle clockwise. Bore Brushes: (8mm, 10mm, 12mm, 15mm, 17mm and 19mm) Used to easily clean the injector bore, tube wall and inner-seat hole. The different bore brushes can be used individually or in any combination needed to perform a proper cleaning. Flexible Extension: Features a flush locking screw for access into hard to reach areas. Driver Handle & Rigid Extension: Features a spring-loaded and quick-lock coupler. 1/4" Drive Hex Shaft - Allows for quick interchange of brushes, drivers, extensions and the use of low speed drills. An Assortment of Swabs: Low-lint, flexible and industrial-grade swab, ranging from 5mm to 20mm in diameter. Used to easily wipe, clean & polish the bores and seat areas after using the brushes. If a seat is really dirty, it may take more than one swab to get it completely clean. Make sure to clean the bore and the inner-seat hole completely without residue.
