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.

Ineed the torqu specs on a 1998 gmc jimmy 4.3litet for the rod and main bearing and oil pump bolts


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

2004 mazda 6 3.0L V6 main bearing caps(bootom end) has 16 bolts need torgue specs please!


Okay, the main bearing caps only have 10 bolts, i think your looking for the connecting rod caps, they have 16 bolts, i will list them both, theres a tightening sequnce for the main bearing caps, these are the caps that hold the crankshaft to the engine block, the connecting rod caps hold the pistons to the crank and they have 16 nuts,For a 2004 mazda 6 with the 3.0 engine the torque specs are as follows.
Connecting rod bolts step 1) 19.2 - 23.6 ft lbs.
step 2) tighten an additional 80 - 100 degrees

Main bearing caps step 1) 32.5 - 33.9 ft. lbs.
step 2) tighten an additional 175 -185 degrees.
heres a diagram for main caps to tighten in order.
hope this is helpful.fc3bff9.gif
