Jeep 4.0 Head Bolt Torque Specs and Sequence
Jeep 4.0 Head Bolt Torque Specs and Sequence with application boundaries, staged installation guidance.
For the 2001 Jeep Cherokee 4.0L, tighten all 14 head bolts to 22 lb-ft and then 45 lb-ft in sequence; finish bolts 1–10 and 12–14 at 110 lb-ft, while bolt 11 finishes at 100 lb-ft.
For the 2001 Jeep Cherokee 4.0L, tighten all 14 head bolts to 22 lb-ft and then 45 lb-ft in sequence; finish bolts 1–10 and 12–14 at 110 lb-ft, while bolt 11 finishes at 100 lb-ft.
These stages apply to the documented 2001 Cherokee 4.0L VIN S factory-bolt procedure. Other years, remanufactured engines, replacement castings, gaskets and aftermarket studs require their exact documentation.
Bolt 11 is deliberately lower than the others and must not be overtightened. The manual also requires a 45-lb-ft verification pass, a final sequence check, and replacement of bolts already carrying a paint mark from an earlier service operation.

Jeep 4.0 Head Bolt Torque Spec
| APPLICATION / ITEM | SPECIFICATION | NOTES |
|---|---|---|
| Pass 1 — all 14 bolts | 22 lb-ft | 30 N·m; exact sequence |
| Pass 2 — all 14 bolts | 45 lb-ft | 61 N·m; then verify all at 45 |
| Final — bolts 1–10 and 12–14 | 110 lb-ft | 149 N·m |
| Final — bolt 11 only | 100 lb-ft | 135 N·m; do not overtighten |
| Previously paint-marked bolts | Replace | Per covered factory procedure |
Bolt 11 is deliberately lower than the others and must not be overtightened. The manual also requires a 45-lb-ft verification pass, a final sequence check, and replacement of bolts already carrying a paint mark from an earlier service operation.
How to use this specification correctly
- 01
Identify the engine code, model year, casting, gasket and exact fastener kit before disassembly.
- 02
Clean and inspect threads, bolt holes and mating faces using the component manufacturer's limits.
- 03
Follow the exact staged pattern with the specified lubricant or sealant; record torque and angle completion.
The complete 2001 Jeep 4.0 tightening stages
Run all 14 positions through 22 lb-ft, then 45 lb-ft in the factory sequence. Verify every bolt is still at 45 lb-ft before the final pass. Bolts 1–10 and 12–14 then finish at 110 lb-ft; bolt 11 alone finishes at 100 lb-ft.
The lower value for bolt 11 is deliberate. Applying 110 lb-ft to it because most of the row uses that figure directly contradicts the manual's caution and can damage the joint.
Bolt identification and reuse control
The covered manual uses 12-point-drive head bolts for rocker-cover clearance. It instructs the technician to paint-mark each bolt after final verification and to replace bolts that already show an earlier service paint mark. That is a service-history control, not decoration.
Keep bolt 11 visibly identified throughout cleaning and installation. Earlier Jeep service information also calls out thread sealant at this special location; confirm the complete 2001 installation section and the selected gasket instructions before applying any chemical.
Checks that torque cannot replace
Inspect the long iron head and block deck to the factory flatness limits, clean the bolt holes, and verify dowels and gasket orientation. If a bolt produces an abnormal feel or reaches its setting before the head is seated, stop and find the cause.
After the final values, check every position in sequence without loosening it. Finish the valve train, manifolds, fluids and initial start according to the full Cherokee procedure; this chart covers the head-bolt stages, not the entire repair.
Why 2001 Cherokee 4.0L Inline-Six identification changes the specification
These stages apply to the documented 2001 Cherokee 4.0L VIN S factory-bolt procedure. Other years, remanufactured engines, replacement castings, gaskets and aftermarket studs require their exact documentation.
Bolt 11 is deliberately lower than the others and must not be overtightened. The manual also requires a 45-lb-ft verification pass, a final sequence check, and replacement of bolts already carrying a paint mark from an earlier service operation.
Assembly controls that prevent false torque
- Use the specified thread condition and lubricant.
- Separate main bolts from small or special-position fasteners.
- Use an angle gauge where torque-to-yield stages are specified.
- Stop if a fastener reaches the setting before the joint seats normally.
Jeep 2001 Cherokee 4.0L Inline-Six specifications can change by model year, engine, platform, wheel, and installed component. Confirm the VIN or engine identity, part numbers, fastener condition, and the current manufacturer instructions before service.
Jeep 4.0 Head Bolt Torque Specs and Sequence FAQs
What are the 2001 Jeep 4.0 head-bolt stages?+
All 14 bolts receive 22 and 45 lb-ft passes. Bolts 1–10 and 12–14 finish at 110 lb-ft; bolt 11 finishes at 100 lb-ft.
Why is Jeep 4.0 head bolt 11 different?+
The factory procedure deliberately assigns bolt 11 a lower 100-lb-ft final value and warns not to overtighten it.
Can previously marked Jeep 4.0 head bolts be reused?+
Not under the covered procedure. It directs replacement when bolts already carry paint from an earlier service operation.
Do aftermarket Jeep 4.0 studs use these stages?+
No assumption is safe. Follow the stud manufacturer's procedure and specified lubricant.
