What is the torque on 2001 buick regal v6 3.8 head bolts

Replace the transmission gasket and rear engine seal. Might check out turbo gaskets too.

Assuming about cylinder head...



Fig. Front cylinder head bolt torque sequence - 3.5L (VIN H) engine

1. Install the cylinder head with a new gasket.
   
2. Install new M11 bolts and M6 bolts.
   
3. Torque the M11 bolts in sequence to:
   1. Step 1: 30 ft. lbs. (40 Nm).
      
   2. Step 2: 100 degree turn.
      
   3. Step 3: 100 degree turn.
      
   
   
4. Torque the long M6 bolt to 22 ft. lbs. (30 Nm).
5. Torque both shorter M6 bolts to 106 inch lbs. (12 Nm).
6. Install or connect the following:
   Lifters Rocker arms Camshafts Primary chain
7. Remove the timing chain holding tool.
8. Install or connect the following:
   Camshaft covers. Torque the bolts to 80 inch lbs. (9 Nm). Exhaust manifold. Torque the bolts to 22 ft. lbs. (30 Nm). Coolant crossover pipe. Torque the bolts to 18 ft. lbs. (25 Nm). Intake manifold. Torque the bolts to 62 inch lbs. (7 Nm). New oil filter Negative battery cable

Hope helps.

for the head

Step 1: Bolts 1 - 8 to 61 N·m (45 ft. lbs.)

† Step 2: Bolts 1 - 8 to 88 N·m (65 ft. lbs.)

† Step 3: Bolts 1 - 8 (again) to 88 N·m (65 ft. lbs.)

† Step 4: Bolts 1 - 8 turn an additional 1/4 Turn.

(Do not use a torque wrench for this step.)

NOTE: Bolt torque after 1/4 turn should be over 122
N·m (90 ft. lbs.). If not, replace the bolt.

Intake Manifold

Bolts . . . . . . . . . . . . . . . . . . . .23 N·m (200 in. lbs.)

Intake Manifold Gasket Retaining

Screws . . . . . . . . . . . . . . . . . .12 N·m (105 in. lbs.)

Intake Manifold Plenum
Bolts . . . . . . . . . . . . . . . . . . . .28 N·m (250 in. lbs.)
the pivot arm ? whats that

I would not recommend doing this work at home. It requires specialized tools, such as a torque wrench, piston ring compressor,and a good manual for torque sequence and values. Furthermore, most blown gasket mishaps require bringing the head surface back to flat and true.

3.8L V6

cylinder head bolts

step 1 37 ft lbs.

step 2 an additional 130 degrees

step 3 4 center bolts an additional 30 degrees

for the 2.2L OHV:
(pully 8 4 1 5 9 <-- long bolts @ 63Nm (46ft/lb)
side ) 7 3 2 6 10 <-- short bolts / 10 is the stud @ 58Nm (43ft/lb)

for the 2.4l dohc are as follows:
(pully 9 3 1 5 7
side) 10 6 2 4 8
bolts 1-8 torqued to 65Nm (40ft/lb)
bolts 9-10 torqued to 40Nm (30ft/lb)

then (either engine) give each an additional 90° (¼) turn

it's best to do the tightening in stages, you don't want to go completely tight on the first pass or there will problems and you'll get to do it all over again

the procedure is too complicated to write in, get a good manual, drain all the fluids, you will have to bringtheheads to a machine shop for inspection, get new head bolts, a good torque wrench and angle meter, buy a complete gasket kit , intake, head, exhaust ,and such, and acouple of days time, mark all the bolts and brackets as you remove them, good idea to take pics as you go along

1. Install the cylinder head gasket. Ensure the arrows point towards the front of the engine. The left cylinder head gasket has the letter L stamped next to the arrow.
   
2. Notice
3. This bolt is designed to permanently stretch when tightened. The correct part number fastener must be used to replace this type of fastener. Do not use a bolt that is stronger in this application. If the correct bolt is not used, the parts will not be tightened correctly. The system or the components may be damaged.
   
   
4. Install the cylinder head.
5. Install new cylinder head bolts. Tighten
   Tighten the cylinder head bolts to 50 N·m (37 lb ft) in sequence.
   
6. Use the J 36660-A to rotate each cylinder head bolt 120 degrees in sequence. Use the J 36660-A to rotate the four center cylinder head bolts an additional 30 degrees in sequence. Refer to Notice Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.
