Those values and most everything else you need for DIY work are contained in the Haynes manual for your vehicle. We have one with each of our vehicles and not only give you the info needed to do repairs yourself but also get an idea of how much work a specific repair should (or shouldn't) cost.

You can also buy these from auto parts stores for a few dollars less and sometimes on eBay for even less.

Hello rdt452428,

For the bearing cap bolts there are two methods.
The preferred method is two steps:

Step one, torque cap bolts to 15 ft.lbs.
Step tow tighten an additional 73 degrees.

The optional method is to torque all cap bolts to 77 ft.lbs.

For the connecting rod nuts its a two step process:

Step one, torque nuts to 20 ft.lbs.
Step two, tighten an additional 70 degrees.

The oil pump to the rear crankshaft bearing cap is torqued to 66 ft.lbs.

I hope this help.

Regards,

netvan
