11115-30040-D0 OEM Cylinder Head Gasket For Toyota 2KD-FTV 2.5 D-4D — 4-Notch 1

Product Description

The Cylinder Head Gasket with OEM reference number 11115-30040-D0 is a verified direct-fit replacement for the Toyota 2KD-FTV 2.5L D-4D common rail turbo-diesel engine-. This gasket is a critical sealing component that sits between the engine block and cylinder head, creating a seal that withstands extreme temperatures and pressures.

The 2KD-FTV engine is a 2.5L four-cylinder, 16-valve, common rail diesel engine widely used across Toyota's global lineup, including the Hilux (KUN25/KUN35) , HiAce (H100/H200) , Dyna / Toyoace (KDY230) , and Land Cruiser Prado. It is a powertrain renowned for its durability, fuel efficiency, and pulling power in commercial, off-road, and heavy-duty appliions.

The cylinder head gasket serves to separate the cooling and oil passages while sealing the combustion chamber. A failing head gasket can lead to serious engine issues including loss of compression, reduced engine power, mixing of coolant and oil, engine overheating, or white smoke from the exhaust. This OE‑spec replacement gasket restores proper engine sealing and performance.

Manufactured as a Multi-Layer Steel (MLS) gasket, this gasket offers superior strength and sealing capabilities under high pressure and temperature conditions — ideal for modern turbo-diesel appliions. This particular variant is identified by 4 notches or holes (Mark D) , indiing a thickness of 1.05 mm-1-5.

Vehicle Compatibility

Primary Appliions (Toyota 2KD-FTV 2.5 D-4D Engine):

Engine Family Details:

• 2KD-FTV — 2.5L, 4-cylinder, 16-valve, DOHC, common rail direct injection, turbocharged, intercooled diesel

• Also compatible with 1KD-FTV (3.0L) appliions where the same gasket family is used

⚠️ Important Thickness Selection:

This gasket is available in multiple thickness grades identified by notches/holes-3-7:

⚠️ Verify the correct thickness for your specific engine appliion before ordering. The required thickness depends on the cylinder head and block machining specifiions. Always consult your vehicle's workshop manual or measure the old gasket.

Installation & Maintenance Recommendations

⚠️ IMPORTANT: Cylinder head gasket replacement requires mechanical competence and proper torque procedures. Professional installation strongly recommended.

When to Replace:

• Engine overheating or coolant loss

• White exhaust steam (coolant burning)

• Oil/coolant cross-contamination (milky substance on oil cap)

• Loss of compression or reduced engine power

• During complete engine overhaul or rebuild

Installation Guidelines (Reference Toyota workshop manual for complete steps):

1. Safety first — allow engine to cool completely before starting work

2. Drain engine oil and coolant

3. Remove cylinder head following manufacturer sequence

4. Thoroughly clean both the cylinder block and cylinder head sealing surfaces — remove all old gasket material

5. Inspect the cylinder head and block for flatness — warpage beyond specifiion requires machining

6. Check cylinder head bolt threads — clean and inspect for damage

7. Verify correct thickness — confirm that 4-notch (1.05mm) is the correct grade for your specific engine

8. Place the new cylinder head gasket on the cylinder block — ensure correct orientation

9. Install cylinder head and torque bolts to manufacturer specifiion in the correct sequence

10. Reassemble all components, refill with fresh oil and coolant

11. Start engine, check for leaks, and perform break-in procedure

Pro Tips:

• Always use new cylinder head bolts (torque-to-yield type must be replaced)

• Have the cylinder head checked for cracks or warpage by a machine shop

• Use the correct torque specifiions — improper installation can negate even the highest-quality gasket
