Hey all.. I just purchased my 07 H3 not long ago & i'm getting close to the 100k mark & was wondering what all I need to change clean check etc. for my 100k mile service.. Thanks in advance

 

Look it up in your owners manual. If you don't have a manual type "Chilton" in the search and look up the maintenance.

 

Or, put Tricia and or Peggy in the search bar....

 

The 100K service is a minor service. Oil and filter change and safety check. At 100K miles though you may find wear and tear items with the visual inspection. Belts, hoses, bushings, motor mounts, leaks, etc are all possible with that type of mileage and use.

 

CORY: Here is a good place to start and what service have you done to your H3 so far??? https://www.hummerforums.com/forum/h...tune-up-24820/

According to the manual 100K service should include the normal oil & Filter plus T-case fluid. If you have not already changed your front and rear diff. fluids now might be a great time to change them. Then you can visually inspect inside!
