The 2.2 engine head bolt tightening sequence typically follows a specific pattern to ensure even pressure across the cylinder head. Start tightening from the center bolts and work your way outward in a spiral pattern, usually in several stages. First, snug the bolts to the specified torque, then tighten them to the final torque specification in the same sequence. Always refer to the manufacturer's service manual for the exact torque values and sequence for your specific engine model.

This sequence appears to be generated by adding the previous two numbers to get the next number. Starting with 2 and 6, we get 2 + 6 = 8. Then, 6 + 8 = 14, 8 + 14 = 22, and 14 + 22 = 36. This pattern follows the Fibonacci sequence, where each number is the sum of the two preceding ones.

For the Opel Corsa 1.8 GSI, the head bolt tightening sequence typically follows a specific pattern to ensure even distribution of pressure. The sequence usually starts from the center bolts and moves outward in a crisscross pattern. The initial torque setting is generally around 30 Nm (22 lb-ft), followed by a further tightening to about 90 Nm (66 lb-ft), and then an additional angle turn of 90 degrees. Always refer to the vehicle's service manual for precise specifications and procedures.
The head bolt torque settings for the Fiat Ducato 1.9 TDI typically require an initial torque of 40 Nm (30 lb-ft) followed by a further tightening to 90° or 180° depending on the specific engine variant. It's important to follow the correct sequence when tightening to ensure an even distribution of pressure. Always consult the vehicle's service manual for the precise specifications and any specific procedures related to the model year.
For the 1999 GM 5.7 Vortec engine, the head torque sequence involves tightening the head bolts in a specific pattern to ensure even pressure across the cylinder head. Typically, the sequence starts from the center bolts and works outward in a crisscross pattern. The initial torque specification is usually set at 22 lb-ft, followed by a further tightening to 44 lb-ft, and finally, a final torque angle of 90 degrees. Always refer to the specific service manual for precise specifications and sequences.
Cylinder head bolt tightening sequence Intake side of engine (Rear) left to right (pass to driver) 8 4 1 5 9 Intake side (frount) left to right 7 3 2 6 10 This is the cylinder head bolt tightening sequence for a 1.9 DOHC engine. Torque as follows: Step 1-First torque=48 ftlbs Step 2-Remove bolts (using the opposite of the tightening sequence) Coat the threads with engine oil reinstall bolts. In sequence tighten first to 22 ftlbs, then to 37 ftlbs. Step 3-Finally tighten all bolts an additional 1/4 turn. Torque Specs for intake: 22ftlbs. The bolts in the rear of the engine (passenger to driverside) are 8 4 1 5 9 In the frount of the engine it is 7 3 2 6 10. It should be a clockwise spiral.
for v6: 8 5 9 12 4 1 13 11 7 3 2 6 10 Step 1) 22 ft-lbs (all) Step 2) Short bolts +55 degrees Medium bolts: +65 degrees Long bolts: +75 degrees
For the 1996 Saturn SL1 1.9 liter 4-cylinder, the torque in sequence one is 22 ft/lbs. In step two, torque in sequence to 37 ft/lbs. In step three, turn all the bolts 90 degrees and double check the final torque in the sequence.
for b16a jdm and b16a2 usdm its 22 lbs first then 63 lbs finall start in middle and work you way out
For a 1999 Chevy Metro, the head bolt torque specifications typically involve a two-step process. First, the bolts should be torqued to 22 lb-ft (30 Nm), and then they should be tightened an additional 90 degrees. It's important to follow the manufacturer's specifications and sequence when tightening to ensure proper sealing and prevent warping. Always consult a repair manual for the most accurate and detailed instructions.
30 nm or 22 inche lbs first run then tourqe 90 degrees third run an aditional 90 degrees all in the proper sequence
If you label the bolt position in the following order: 1 (left/front) - 2 - 3 - 4 - 5 (right/front) 6 (left/rear) - 7 - 8 - 9 - 10 (right/rear) The torque sequnce is: 8 - 3 - 7 - 4 - 9 - 2 - 10 - 1 - 6 - 5 Use 22 foot-pound on the 1st pass, 49 foot-pound on the 2nd pass.
The torque setting for the cylinder head on a Yamaha QT50 is typically around 18-22 ft-lbs (24-30 Nm). It's important to follow a specific tightening sequence and to ensure that the head is torqued evenly to prevent warping. Always consult the service manual for the most accurate specifications and guidelines specific to your model.
