Isuzu's Injector Sleeve Replacement Tool 

This kit includes the tools necessary for both removing & properly re-installing the injector sleeve.  This is a critical tool if you are servicing 4HK-1 & 6HK-1 engines.  If the proper tools are not used the injector sleeve will likely leak oil & or coolant.

This tool allows the cylinder head to remain installed on the block to perform this service.
