The following is verbatum from the mitsu engine overhaul manual... Steps 7 and 8 are a bit cryptic, but it seems like after you tighten the bolts to 20nm in the CORRECT PATTERN... you then go around tightening 1/4 turn through the pattern, then a final 1/4 turn through the pattern... do NOT tighten each bolt to 20, the 1/4 then another 1/4 before going to the next bolt, the idea is to get EVEN tightening across the head, so tighten her three times around the pattern! Now for the verbiage from Mitsu's overhaul manual...


(1) When installing the cylinder head bolts, check that the
shank length of each bolt meets the limit. If the limit is
exceeded, replace the bolt. - Limit: Max. 96.4 mm (3.79 in.)
(2) Install the washers.
(3) Apply engine oil to the bolt threads and washers.
(4) According to the tightening sequence, tighten the bolts to
75 Nm (54 ft.lbs.).
(5) Loosen the bolts completely.
(6) Torque the bolts to 20 Nm (14.5 -ft.lbs.)
(7) Tighten the bolts l/4 turns (90”) more.
(8) Tighten the bolts l/4 turns (90”) additionally.

What is the cylinder head bolt torque settings fir a 4g69 mitsubishi engine ?


BOLT INSTALLATION


Apply engine oil to the thread of the bolts and to the washers.
Tighten the bolts to the specified torque, using the tightening sequence shown.
Tightening torque: 54 ft-lb +/- 2 ft-lb
Loosen all bolts fully in the reverse order of tightening.
Re-tighten the loosened bolts to the specified torque in the tightening sequence shown.
Tightening torque: 15 ft-lb +/- 1 ft-lb
This step is to make it easier to ensure you are making 90 degree turns. Make a paint mark across each bolt head and cylinder head.
Tighten the cylinder head bolts 90 degrees in the specified order.
Tighten the bolts another 90 degrees in the specified order and check that the paint marks on the cylinder head bolts are aligned with the paint marks on the cylinder head.

Head torque specs for 92 honda accord with f22a1


Thanks for using FixYa.

To install:
  1. Install a new head gasket on the engine, making certain it is positioned correctly. The cylinder head dowel pins and the oil jet must be in place. Refer to the illustrations if necessary.
  2. Install the head. Lower it straight down onto the block, aligning it correctly.
  3. Apply clean engine oil to the bolt threads and the contact face of the bolt head. Install the head bolts finger-tight.
  4. On all models except 1988-89 DOHC Prelude and 1992-95 Preludes with 2.3L and VTEC engines, tighten the head bolts following sequence A. On 1988-89 DOHC Preludes, use sequence B. Use sequence C on 1992-95 Preludes with 2.3L and VTEC engines.
    1. On 1984-89 Accords and 1984-91 Preludes, tighten the bolts in two passes. The first pass should bring the bolts to about 22 ft. lbs. (30 Nm). On the second pass, tighten the bolts to their final torque of 49 ft. lbs. (68 Nm).
    2. On 1990-93 Accords, tighten the bolts to 29 ft. lbs. (40 Nm) on the first pass, 51 ft. lbs. (70 Nm) on the second pass, then tighten the bolts to their final torque of 78 ft. lbs. (108 Nm).
    3. On 1994-95 Accords and 1992-95 Preludes, the bolts are also tightened in three passes. Tighten the bolts to 29 ft. lbs. (40 Nm) on the first pass, 51 ft. lbs. (70 Nm) on the second pass, then tighten the bolts to their final torque of 72 ft. lbs. (100 Nm).

  6. If applicable, install the cam, rockers and camshaft holders.
  7. If equipped, install the EGR crossover and air suction pipes.
  8. Connect the exhaust pipe to the manifold using new nuts.
  9. Install the timing belt.
  10. Install the valve cover.
  11. Install the cylinder sensor (if equipped) and the distributor.
  12. If applicable, install the alternator.
  13. Install the power steering pump, then connect the inlet hose to the pump.
  14. Install the accessory drive belts. Adjust the belt tensions.
  15. Install the heater hoses.
  16. Install the cruise control actuator if it was removed.
  17. Connect the spark plug wires. Connect all the wire harnesses and vacuum hoses to the cylinder head, intake manifold and throttle body/carburetor.
  18. Connect the throttle control cable and/or accelerator cable at the throttle body.
  19. Connect the fuel lines.
  20. Install the brake booster, PCV and charcoal canister vacuum hoses.
  21. Install the air cleaner and intake duct.
  22. Refill the engine coolant. It is recommended that the engine oil be changed whenever a cylinder head is removed.
  23. Connect the negative battery cable.
  24. Start the engine, allowing it to idle. Bleed the cooling system. Check the work area carefully for any signs of fluid leakage or any indication of the timing belt rubbing or slapping the covers.

Can you tell me the torque spec.on head bolts for a 1985 ltd 3.8 thank you


Six IN LINE - 6L

zjlimited_510.jpg

Fig.: Cylinder head torque sequence - 6 -cylinder engine



Cylinder head torquing should proceed in three steps and in the prescribed order. Tighten them first to 50-55 ft. lbs. (65-71 Nm), then give them a second tightening to 60-65 ft. lbs. (78-84 Nm). The final step is to 70-75 ft. lbs. (91-97 Nm), at which they should remain undisturbed.


Six IN V - 6V

Fig.: Cylinder head bolt torque sequence - 6 -cylinder engine

Tighten the head, according to the illustrated sequence in three progressive steps. Tighten the bolts to 50-55 ft. lbs. (68-74 Nm), then 60-65 ft. lbs. (81-88 Nm) and finally to 75 ft. lbs. (102 Nm).


Hope this helps (remember to rate and commene this answer).

What is the right Torque Specification of the cylinder head bolt,main bearing and connecting rod bearing for a 1997 Ford F 150 4.2 liter? Thank you...


Cylinder heat bolt torque:
Torque sequence --------- front | 7 3 1 5 | | 8 4 2 6 | --------- Step 1: Torque all bolts in sequence to 14 Ft/Lbs Step 2: Torque all bolts in sequence to 29 Ft/Lbs Step 3: Torque all bolts in sequence to 36 Ft/Lbs Step 4: in the sequence, loosen the cylinder head bolts three turns. Step 5: Tighten short bolt to 15 - 32 Ft/Lbs Step 6: Tighten long bolt to 30 - 36 Ft/Lbs Step 7: Tighten all bolt to 175- 185 degree note: Do not loosen all of the cylinder head bolts at one time. Each cylinder head bolt must be loosened and the final tightening prior on the next bolt in the sequence.
Main bearing torque:
Torque sequence: Step 1: torque bolts to 91 Ft/Lbs with the exception of the rear main bearing cap Step 2: torque rear main bearing cap bolts to 88 Ft/Lbs Step 3: torque brace bolts to 40 Ft/Lbs
Connecting rod torque:
Torque sequence Step 1: Torque to 29 Ft/Lbs Step 2: Turn an additional 90 degrees
