SOURCE: What is the tension on cylinder head bolts for a

Would like to state the cylinder head Torque Values, Torque Pattern, and Tightening Sequence, plus additional tips.
[I know it's more than you asked for, but after you read the entire answer here, I believe you'll know why I stated it this way]

Torque Pattern:
Top of head starting from Left going Right,
8, 4, 1, 5, and 9
Bottom of head, (Exhaust manifold side), starting from Left going Right,
7, 3, 6, 2, and 10

You're supposed to use old bolts with the head cut off, (Alignment Dowels), in bolt holes 8 and 10. This way you goop the gasket, and install it, then slide the head on. Place the head bolts in, SNUG them down. Remove those alignment dowels. Then put bolts 8 and 10 in place.
After the head of the bolt is cut off, you saw a slot in the top of the bolt. Helps when you remove it. (Have any old bolts that are long enough for this, and have the correct threads?)

=>Coat No.7 bolt with thread sealant.

Tightening Sequence:
Step 1: Tighten all bolts to 22 Foot Pounds. (30Nm) (Using the above Torque Pattern)

Step 2: Tighten all bolts to 45 Foot Pounds. (61NM)

Step 3: Tighten 1 Through 6 <- to 110 Foot Pounds. (149Nm) DO NOT TIGHTEN No.7 bolt yet!

Step 4: Tighten No.7 bolt to 100 Foot Pounds. (136Nm) DO NOT TIGHTEN further! It only tightens to 100 Ft.Lbs. (136Nm)

Step 5: Tighten bolt 8 Through 10 to 110 Foot Pounds. (149Nm)

Step 6: Repeat Steps 3 , 4, and 5

SOURCE: How to remove/install a 4 cylinder jeep Yj

If you need to ask, you have never done one. I suggest that you get a chiltons or haynes manual to guide you through it. tips are: use large bolts without heads to guide the transmission back onto bellhousing so you don't need to hang the unit on the clutch disc and risk bending it. Change the pilot bearing in the back of the crankshaft if it's the least bit worn, be very careful not to damage the crank sensor on the bellhousing, and use a good pilot shaft when aligning the disc inside the clutch cover. spread some white lube on the input shaft and front guide collar on the transmission and make sure the throwout bearing has sufficient grease in the inside groove.
good luck!!!

3.1l diesel. What is the correct head gasket?


no year? Jeep? one post, and no year.
is this WG jeep say in europe. ? we dont have WG here.
WG started in Europe in 1999.
on this usa forum or in our country no 3.1 VM diesels
i do have your FSM book.
and here is what it states. (different liners used etc)
"CYLINDER HEAD GASKETS
A one piece steel cylinder head gasket is used for
all five cylinder heads.
Cylinder head gaskets are available in three thicknesses.
Identification holes or notches in the right
front corner of the gasket indicate the thickness of
the gasket (Fig. 65).
CAUTION: Piston protrusion must be measured, to
determine cylinder head gasket thickness, if one or
more cylinder wall liners have been replaced.
NOTE: If cylinder wall liners have not been
removed; the same thickness head gasket removed,
may be used.
MEASURING PISTON PROTRUSION
(1) Use special tool VM.1010 with dial indicator
special tool VM.1013 (Fig. 66).
(2) Bring the piston of cylinder no. 1 exactly to top
dead center.
(3) Zero the dial indicator on the cylinder block
mating surface.
(4) Setup the dial indicator on the piston crown
(above the center of the piston pin) 5mm (1/8 in.)
from the edge of the piston and note the measurement
(Fig. 67).
(5) Repeat the procedure with the rest of the cylinders.
(6) Establish the thickness of the steel gasket for
all four cylinder heads on the basis of the greatest
piston protrusion (Fig. 65)
buy the book,end all guessing?

Refer to torque specifications.
(8) Install 6 ignition coils. Refer to Ignition Coil
Removal/Installation.
(9) Connect electrical connectors to throttle body.
(10) Connect electrical connectors at all fuel injectors.
To install connector, refer to (Fig. 37). Push connector
onto injector (1) and then push and lock red
colored slider (2). Verify connector is locked to injector
by lightly tugging on connector.
(11) Connect necessary vacuum lines to throttle

I want torque setting for jeep 3.7l on cylinder head


Hi there:
Install the cylinder heads. Use new gaskets and tighten the bolts, in sequence, as follows:
  1. Step 1: Bolts 1-8 to 20 ft. lbs. (27 Nm)
  2. Step 2: Bolts 1-10 verify torque without loosening
  3. Step 3: Bolts 9-12 to 10 ft. lbs. (14 Nm)
  4. Step 4: Bolts 1-8 plus 1 / 4 (90 degree) turn
  5. Step 5: Bolts 9-12 to 19 ft. lbs. (26 Nm)

Just did a cylinder compression test on a 1989 jeep wrangler 2.5l the numbers I got are bad. what do you guys think? 1. 40psi 2. 0psi 3. 65psi 4. 55psi


0 psi and you have to ask? There is something terribly wrong in the second cylinder, you will have to at least remove the head to find out what.

What is the torque specs for a 1998 jeep Cherokee classic straight 6 4.0 liter? I am replacing the head gasket and need to find the lbs of torque. Thank you for any advice, pictures, etc.


Torque sequence ------------------ front | 12 8 4 1 5 9 13 | of | | engine | 11 7 3 2 6 10 14 | ------------------ Final torque must be reached in 3 equal steps Step 1: torque all bolts (except bolt 11) to 110 Ft/Lbs Step 2: torque bolt 11 to 100 Ft/Lbs Recheck final torque in sequence.

  1. Disconnect the negative battery cable.
  2. Drain the cooling system.
  3. Disconnect the hoses at the thermostat housing.
  4. Properly relieve the fuel system pressure.
  5. Remove the cylinder head cover.
  6. Loosen the rocker arms.
  7. Remove the pushrods.

The valvetrain components must be replaced in their original positions.
  1. Remove the intake and exhaust manifold from the cylinder head.
  2. Disconnect the spark plug wires and remove the spark plugs.
  3. Disconnect the temperature sending unit wire, ignition coil and bracket assembly from the engine.
  4. Remove the accessory drive belt(s).
  5. Unbolt and set aside the power steering pump and bracket. Do not disconnect the hoses.
  6. Remove the intake and exhaust manifold assembly.
  7. If equipped with A/C, perform the following:
    1. Remove the compressor and position it aside with the lines attached.
    2. Remove the compressor bracket bolts from the cylinder head.
    3. Loosen the through bolt at the bottom of the bracket.

  8. Remove the alternator.
  9. Remove the cylinder head bolts, the cylinder head and gasket from the block.

Bolt No. 14 cannot be removed until the head is moved forward. Pull the bolt out as far as it will go and suspend in place by wrapping with tape.
  1. Discard the gasket. Thoroughly clean the head-to-block mating surface.
  2. Clean and inspect the cylinder head thoroughly. Refer to the engine reconditioning portion outlined later in this section.

To install:
  1. Coat a new head gasket with suitable sealing compound and place it on the block. Most replacement gaskets will have the word TOP stamped on them.

Apply sealing compound only to the cylinder head gasket. Do not allow sealing compound to enter the cylinder bore.

Fill the oil level on a 1994 Jeep Grand Cherokee,


yes you should remove the access. This will cause the engine to drown in a sense and have to fight. It is always safe to put in not enough to too much. You onlt have a certain amount of oil that can be placed in the pan before it runs up into your cylinder heads and can break the seal on the gasket. Then you would have to pay to get the cylinder head gasket replaced.
