The download I received was a complete waste of my money. Was not even close to what it was represented as. I thought I was getting a proper service repair manual. What I got was a collection of service bulletins. I sent an email to your company right after I looked through it requesting my money back. Have yet to hear a response. Terry Muich

It was much larger than i expected. 5 documents at 12k pages each. Its not something ill actually be able read but its easy enough to find what you need..
The Ford F250 manual is much easier to navigate at just over 8000 pages.
If i spend the money for Adobe Acrobat Professional ill be able to break it down into manageable bits.
Both manuals area great value for the money.

would rather have a maintenance manual. have a parts manual from parts vu company. only difference is that your parts manual has all together whereas the parts vu had to download the differsections individually.

Our original order was supposed to be for our 2014 Subaru Outback, yet the manual came up as Forester. We did have to purchase a new manual in order for them to send us the correct manual. We hope it will help us repair our Subaru.

Trims

  • 80th Anniversary Crew Cab Pickup
  • High Altitude Crew Cab Pickup

Known issues on the 2021 Gladiator. Five recalls are on federal record for this model year: two power-train recalls for overheated clutch components that can increase the risk of a fire, a rearview camera that does not display an image and reduces the driver's rear view (crash risk), a gasoline fuel-pump fault that can cause an engine stall, and a diesel fuel-pump failure that can also stall the engine — both raising crash risk. Owners have filed 424 complaints and 682 technical service bulletins are on record for the year.

From a routine service interval to a hard-to-trace wiring fault, it keeps you on the factory procedure and the correct specification for your specific 2021 Gladiator.
