Installation Notes and Tips

Verify engine code and application details before ordering, since fitment notes vary by model and year. This kit includes chain guides and a tensioner, but gaskets are not included and the drive sprocket is not included. For Saturn Vue and certain Saturn Ion, L300, L200, and LW200 applications, review the listed configuration notes carefully before installation. Professional timing service procedures should be followed to confirm cam and crank timing alignment during assembly.

The brand’s kit design focuses on replacing the wear items commonly serviced together, helping reduce the chance of repeat timing work on the same engine.
