Kelley's Works in Progress
Bolt Torque Tables
Since this sort of thing gets asked a lot on the various fora that I visit, I thought I'd collect all of this in one place.
There are, obviously, going to be a number of pages to make this work - it's a lot of information! I've elected to break this down as a single model per page, the you'll find the charts on each page organised by model year and by system. I'll also be generating a page for each engine - and possibly for other components as well.
Naturally, I'll add more as I find it. My library of factory literature is still incomplete, and I'd prefer to use factory/manufacturer literature for critical specifications like this.
Please note that there may be some "odd" inclusions in the torque table - for instance, I'm reasonably certain that the AMC 2.46L I4 was not offered in the SJ. However, until reserach yields a definitive answer, I shall continue with such inclusions - I'd sooner err on the side of caution and have information that is unneeded than to have to add it later... It's easier to delete rows in a table!
In order to simplify matters, I have elected to organise the tables first by vehicle model/year, and then organise the individual charts by system. I will probably have to revise these a few times, since it is logical to repeat certain values in different sections. However, you should be able to find what you need.

Abbreviations -
- ABS - Antilock Braking System. Used in "Brakes" section to denote ABS-Specific hardware, which can be ignored if you don't have ABS.
- AIR/A.I.R. - Air Injection Reactor (system.) This is what the underhood "air pump" or "smog pump" does - shoot frexh air into the ehxuast system to provide extra oxygen to complete combustion of HC and CO emissions.
- ECU - Electronic Control Unit. Typically used in the "Brakes" section
- EGR - Exhaust Gas Recirculation. Used to identify EGR system components
- HCU - Hydraulic Control Unit. Always used in the "Brakes" section
- LHD - Left-hand Drive.
- RHD - Right-hand Drive. "Dispatcher" (mail Jeep) and British market production vehicles
Explanatory Notes
- Cells highlighted in white have no data available
- Cells highlighted in blue have no verified data available. This is generally reserved for bolt/screw/nut sizes, and if you can provide measurements, I'd like to get them!
- Items under 20 pound-feet/240 pound-inches of torque are given in both units, where they come out in even pound-feet. This allows the use of a pound-foot or pound-inch calibrated torque wrench, depending on what you have available.
- Rows and values highlighted in red are listings for conditions other than "clean, dry" threads. Lubricant specified is given after the application in parenthesis.
- If you use engine oil or grease to lubricate "clean, dry" threads on assembly, reduce given torque values by one-quarter.
- If you use some form of anti-seize compound to lubricate "clean, dry" threads on assembly, reduce given torque values by one-half.
- No change is necessary to given torque values when a threadlocker compound is used on the threads.
- Rows highlighted in green are separators for various systems, to make torque values easier to find.
