Product Description
Cylinder Head Gasket 11115-58151 For Toyota 15B-FTE 4.1L Diesel
The cylinder head gasket carrying Toyota OEM number 11115-58151 (also 1111558151) seals the interface between the cylinder head and engine block on Toyota's high-durability 15B-FTE 4.1L inline-four turbo-diesel engine. This gasket is the 1.4mm thickness grade in Toyota's multi-thickness system for the 15B engine family.
| Part Number: | 11115-58151 | Product Name: | Cylinder Head Gasket |
| Car Model: | Toyota Dyna Mega Cruiser Coaster | Engine Model: | Toyota 15B-FTE 4.1L Diesel |
| Condition: | 100% Brand New | Size: | Standard |
| Material: | Multi-layer steel (MLS) | Thickness: | 1.40 mm |
Thickness Grades - 15B Diesel Family
The Toyota 15B diesel engine uses three different head gasket thickness grades depending on piston protrusion measurement. The correct thickness is determined by the highest protrusion measurement across all four cylinders.
| OE Number | Thickness | Notes |
|---|---|---|
| 11115-58130 | 1.20 mm | Thinnest - for lowest piston protrusion |
| 11115-58140 | 1.30 mm | Medium thickness |
| 11115-58151 | 1.40 mm | Standard thickness for 15B-FTE - this product |
Selecting the correct thickness is essential for proper engine performance and valve clearance.

1.4 mm Thickness - Factory Specification: Delivers compressed thickness of 1.4 mm as confirmed by Japanese notation 厚さ＝１．４０ in Toyota parts catalogue.
Precision 109.5 mm Gasket Bore: Designed specifically for 108 mm pistons with dimensions of 109.5 mm diameter × 197 mm width × 503 mm length.
OE-Grade Replacement: Exact Toyota part number for 15B-FTE engines in Dyna, Mega Cruiser, and Coaster vehicles.
Genuine Toyota OEM - Japanese Quality: Manufactured to original engineering specifications with "Made in Japan" origin assurance.
Quality Control & Verification
| QC Item | Verification Method |
|---|---|
| Fire ring bore alignment | Laser measurement - 109.5 mm ±0.03 mm tolerance |
| Gasket thickness (compressed) | Digital micrometer - verified against 1.40 mm specification |
| Layer registration | Optical inspection - all MLS layers align within 0.2 mm |
| Fire ring material | Spectrographic analysis - stainless steel grade confirmed |
Installation & Maintenance Recommendations
⚠️ IMPORTANT: The 15B-FTE uses torque-to-yield (stretch) cylinder head bolts. These are single-use fasteners and must be replaced with new units whenever the cylinder head is removed.
Why thickness selection matters: The 15B-FTE is a high-compression diesel engine (17.8:1). Correct head gasket thickness is determined by piston protrusion measurement.
Recommended Replacement Indicators
| Symptom | Diagnosis |
|---|---|
| Gradual coolant loss with no visible external leak | Coolant escaping past fire ring into combustion chamber |
| White or grey steam from exhaust | Coolant burning in combustion chamber |
| Bubbles in coolant overflow bottle | Combustion gases entering cooling system |
| Milky oil residue under filler cap | Coolant mixed with engine oil |
Maintenance Schedule
| Service Item | Interval |
|---|---|
| Replace engine coolant | Every 4-5 years or 80,000-100,000 km |
| Check for coolant loss and pressurized hoses | Monthly |
| Change engine oil and filter | Every 5,000 km |
