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.

Applications

This Toyota 15B-FTE cylinder head gasket directly replaces the factory sealing component in the following configurations:

Dyna / ToyoAce Commercial Chassis

Chassis / Series	Model	Years	Engine Variant
BU400, BU410, BU420, BU430	Toyota Dyna / ToyoAce	08.1999 - 06.2004	15B-FTE

Mega Cruiser Off-Road Vehicle

Chassis	Model	Years	Engine Variant
BXD20V	Toyota Mega Cruiser (KC-BXD20V)	1999 - 2001	15B-FTE

Coaster Bus (B40 / B50 Series)

Chassis	Model	Years	Engine Variant
B40 / B50	Toyota Coaster Bus	1999 - 2004	15B-FTE, 15B-FT

Features & Benefits

Multi-Layer Steel (MLS) Construction: Withstands sustained cylinder pressures of high-compression diesel operation with stainless steel fire rings that resist corrosion and maintain spring force at high temperatures.

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

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
