Torque depends on the size of the bolt as you have already specified grade 8.8.
Here are some recommended settings:
M8 (13mm across the flat head) 25Nm
M10 (17mm across the flat head) 49Nm
M16 (24mm across the flat head) 210Nm
18 ft/lbs for the nuts 11 ft/lbs for the bolts http://www.zenitram-inc.com/Manuals/PhazerCrank.jpg
the main caps are 75 pounds of torque. but i dont know the rod breaing specs.
Tightening the bolts in the typical order from the middle out, the upper intake bolts torque in first pass at 44 in lbs, the second pass at 88 in lbs. The lower intake bolts start with 27 in lbsfor the first pass, 106 in lbs for the second pass and 133 in lbs for the last pass.
* 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.)
The torque specifications for the cylinder head bolts on a 1994 Plymouth Voyager with a 3.0L engine are typically around 65 ft-lbs (88 Nm). It's important to follow a specific tightening sequence and to ensure that the bolts are torqued in stages if required. Always consult a repair manual for the exact procedure and specifications to ensure accuracy.
The torque specifications for the Ford Festiva 1.3 engine vary depending on the component. For the cylinder head bolts, the typical torque is around 60-65 ft-lbs (81-88 Nm), while the main bearing caps usually require about 50-55 ft-lbs (68-75 Nm). Always refer to the vehicle's service manual for the most accurate and specific torque settings.
2.4L * First All to 34 N·m (25 ft. lbs.) * Second All to 82 N·m (60 ft. lbs.) * Third All to 82 N·m (60 ft. lbs.) CAUTION: Do not use a torque wrench for the following step. * Fourth Turn an additional 1/4 Turn, 3.3L, 3.8L * 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.)
AnswerIf this is the V-6, then you must have a common problem...lower intake leaks coolant.The torque spec for the lower manifold is:First pass: 60 inch poundsSecond pass: 110 inch poundsLast (outer bolts only): 18 foot poundsUpper intake is a total 88 inch pounds in at least two steps.Randy
For a 1991 Geo Metro, the cylinder head bolt specifications typically include a torque setting of 65 ft-lbs (88 Nm) for the bolts. It's important to follow the proper tightening sequence and to use a torque wrench for accuracy. Additionally, it’s advisable to use new bolts, as they can stretch and lose their effectiveness over time. Always refer to the vehicle's service manual for the most accurate and detailed specifications.
The torque specifications for the Isuzu 3LB1 engine cylinder head bolts typically require a torque of 58-65 ft-lbs (79-88 Nm) in several stages, often involving a sequence of initial lower torque followed by a final tightening. It's essential to follow the specific tightening sequence recommended by the manufacturer to ensure even pressure across the head. Always consult the service manual for the most accurate and detailed specifications for your particular model.
for 88 thru 95 Step 1. Tighten all 10 bolts in sequence to 14 ft/lbs (20 Nm). Step 2. Tighten all 10 bolts in sequence to 36 ft/lbs (49 Nm). Step 3. Tighten all 10 bolts in sequence to 49 ft/lbs (67 Nm). Step 4. Tighten bolts 1 and 2 to 49 ft/lbs (67 Nm) again.
sequence is from the center out. torque in 3 stages. first 25 ft lbs second tighten 90 degrees [1/4] turn third tighten 90 degrees [1/4] turn. you're done.
