Cylinder Head Gasket 11115-54073-F0 1111554073F0 For Toyota Land Cruiser/Hilux 3L 2.8L Diesel — OEM Multi-Layer Steel (MLS) F-Grade (Thickest) 1.65mm

The Cylinder Head Gasket with Genuine Toyota OEM number 11115-54073-F0 (also listed as 1111554073F0) is a verified direct-fit replacement for the Toyota 3L (2.8L) diesel engine. This critical component provides a seal between the engine block and cylinder head to contain combustion pressure and prevent oil and coolant mixing.

If your cylinder head gasket is failing, you may experience:

• Engine Overheating: Temperature gauge consistently rising above normal
• Coolant Loss: Unexplained drop in coolant level with no visible external leaks
• White Smoke from Exhaust: Steam-like white smoke indicating coolant entering combustion chamber
• Oil Contamination: Milky or frothy appearance on oil dipstick or oil filler cap
• Loss of Engine Power: Significant reduction in engine performance due to compression loss

How to Determine the Correct Gasket:

• Check the mark (B, D, or F) stamped on your original gasket
• The correct gasket thickness is determined by the piston protrusion from the cylinder block upper surface
• Always verify with your vehicle's engine code and VIN for precise identification

Compatible Models — Toyota:

As a Genuine Toyota OEM part, each head gasket meets Toyota's stringent quality standards.

Replacing a cylinder head gasket requires proper torque specifications, correct gasket positioning, and thorough engine component inspection.

Pre-Installation Checklist:

• Verify gasket mark matches the original — confirm F-Grade designation
• The cylinder head gasket thickness is determined by the piston protrusion from the cylinder block upper surface
• Inspect cylinder head and engine block sealing surfaces for warpage or damage — resurface if necessary
• Clean all sealing surfaces thoroughly — any debris can cause premature gasket failure
• Check cylinder head bolt threads and replace if damaged
• Use new cylinder head bolts as recommended by the workshop manual

Installation Guidelines (Reference Toyota workshop manual):

1. Ensure the engine is completely disassembled with the cylinder head removed
2. Clean the cylinder head and engine block sealing surfaces with appropriate solvent
3. Check the flatness of both surfaces using a precision straightedge and feeler gauge
4. CRITICAL: Position the new gasket correctly — ensure the F-mark orientation matches OEM specifications
5. Install the cylinder head onto the gasket
6. CRITICAL: Follow the angular tightening method specified in the Toyota workshop manual
7. Torque cylinder head bolts in the correct sequence and to the specified torque values
8. Reassemble remaining engine components
9. Refill with fresh coolant and engine oil
10. Start the engine and check for leaks
11. Perform a cooling system pressure test to verify seal integrity

Maintenance Schedule:

• Inspection: During any cooling system service or if overheating symptoms appear
• Replacement: Immediately if failure symptoms appear. Also recommended during major engine overhauls

• Packaging: Each cylinder head gasket is securely packed in Genuine Toyota OEM packaging
• Suitable for: Wholesale distributors, engine rebuild shops, 4×4 specialty shops, commercial vehicle repair shops, and fleet owners
