Most auto parts stores should be able to print off a spec sheet for the torque specs. They will need to know the year and model it came out of if not original engine.
First you need to know the diameter of the bolts and the type of thread ie 3/8 N/C or 5/16 N/F then look at the type of bolt ie plain steel or high tensile SAE grade 3, 4, or 6, once you know this go to a general purpose bolt torque chart, and derive the torque spec info.
If the engine block is cast iron use the full torque specification.
If the engine block is alloy then reduce the torque spec 10%
Below is an example of a general purpose bolt / nut torque chart
Exhaust Manifold To Cylinder Head - 9.58 ft lbs
Exhaust Pipe To Exhaust Manifold - 20 ft lbs
you can check it out here, also all other torque specs for your engine. Torque Specs Database
INSTALL OIL COOLER
-clean the oil cooler contact surface on the oil cooled mounting
-install a new O-ring to the oil cooler.
-temporarily install the oil cooler with the nut
-apply a light coat of engine oi on the threads and under the head of the relief vale
-install the plate washer and union bolt. torque 78Nm (800kgfcm, 58 ft lbs.)
-tighten the nut,torque 8.8Nm (90kgfcm, 78 inch lbs.)
-connect the 2 water bypass hoses to the oil cooler.
The torque settings is more know as torque spec's, and it just means an exact measurement of how tight a paticular part is tightend. With a new engine, many differnt parts have differnt specs, but hands down the single most important thing would be the cylinder head to engine block torque. This is often done in a 3 step process, using a torque wrench, and a torque angle gauge. Are you planing on installing an engine yourself? I can get specs for you.
Head Bolt Torque
For your 1994 Oldsmobile Cutlass Supreme (3.4L SFI DOHC):
Foot pounds (Final torque)
Note:
Torque sequence --------- | 6 2 3 7 | | 5 1 4 8 | --------- Step 1: torque in sequence to 33 Ft/Lbs Step 2: turn an additional 90 degrees Recheck final torque in sequence *** CAUTION ***engine uses Torque To Yield head bolts (TTY) thatpermanently stretch during the initial installation.New head bolts must be used when cylinder head isreplaced or re-installed to obtain proper torque.
