Toyota Diesel 2L-T/2L-TE Head Gasket 11115-54084-F0

Product Overview

Genuine Toyota cylinder head gasket 11115-54084-F0 for the 2L, 2L-T, and 2L-TE 2.4L (2,446cc) SOHC diesel engines, built with a multi-layer steel (MLS) core, 1.55mm compressed thickness, and a 93.5mm sealing bore. This is the current F0 revision of a gasket Toyota issued under five sequential catalog numbers over its production life (11115-54080 through 11115-54084).  This single gasket covers an unusually wide range of Toyota and VW-badged diesel trucks, SUVs, and vans built on the 2L/2L-T platform, from the 1997-2001 Hilux and HiAce through the early Land Cruiser Prado, 4Runner II, Dyna, and even the UK Metrocab taxi and VW Taro. 

OEM & Cross-Reference Part Numbers

• 11115-54084-F0 (Toyota OEM, current revision — this listing)
• 11115-54083 (Toyota OEM, previous catalog number, same gasket)
• 11115-54082 (Toyota OEM, previous catalog number, same gasket)
• 11115-54081 (Toyota OEM, previous catalog number, same gasket)
• 11115-54080 (Toyota OEM, earliest catalog number in this series; also quoted against the early Land Cruiser Prado LJ78 2L-TE in some owner parts lookups)

 

Key Features & Benefits

• One gasket, broad platform coverage: The same physical part sold under five Toyota catalog numbers (54080 through 54084), so this single listing covers Hilux, 4Runner, Land Cruiser Prado, HiAce, Dyna, and several export-market diesel applications.
• Multi-layer steel construction: MLS design seals more consistently across repeated heat cycles than single-layer composite gaskets, which matters on a diesel engine family known for cooling-related head failures.
• Confirmed sealing geometry: 1.55mm compressed thickness and 93.5mm bore matched to the 92mm cylinder bore of the 2L/2L-T/2L-TE block, with 2 locating holes for correct alignment during installation.
• Matched to a specific piston protrusion range: Correct for engines measuring 0.78mm to 0.87mm piston protrusion, a useful reference point if you're unsure which gasket thickness your rebuild needs.
• Avoids the direct-tappet versus rocker-arm mismatch: Built specifically for the later direct-tappet 2L/2L-T head design, so you're not stuck with a gasket that looks right on paper but doesn't match your engine's valvetrain generation.

Installation & Maintenance

Installation Difficulty: Advanced / Expert
Tools Required: Torque wrench with the correct head bolt sequence, timing belt tools, feeler gauges for valve clearance, straightedge for head flatness verification, complete diesel engine toolkit
Professional Installation: Strongly recommended. Getting the torque sequence and head flatness check right matters just as much as the gasket itself on this engine family.

Maintenance Tips:

• Always install new head bolts with a new head gasket.  Diesel head bolts are stretch-type fasteners, and reusing them is a common cause of early gasket failure.
• Measure piston protrusion before final installation to confirm it falls within the 0.78mm to 0.87mm range this gasket is built for.
• Have the head checked for flatness before reinstalling, even if it looks undamaged.
• Fully bleed the cooling system after reassembly. Trapped air pockets are a common cause of comeback overheating complaints on 2L/2L-T engines.

 

Frequently Asked Questions

Q: What does the F0 suffix mean on Toyota part number 11115-54084-F0?
A: F0 is the specific revision mark Toyota currently issues for this gasket. It's the version supplied under the 11115-54084 catalog number today, as opposed to earlier revisions or the four earlier catalog numbers (54080 through 54083) that cover the same physical part.

Q: Does this gasket fit both naturally aspirated and turbo engines?
A: Yes. It's confirmed for the 2L naturally aspirated diesel, the 2L-T turbo diesel, and the 2L-TE turbo diesel with electronic injection, as long as the engine uses the direct-tappet head generation described above.

Q: Will this gasket fit my early 2L or 2L-T engine from the 1980s?
A: Possibly not. Toyota switched this engine family from a rocker-arm valvetrain to a direct-tappet design partway through production, and this gasket is built for the direct-tappet generation. An early rocker-arm head is not a confirmed match even if the model and year look close. Check your head casting or the Mark letter on your old gasket before ordering.

Q: My vehicle isn't in the fitment table. Could this gasket still be correct?
A: It's possible. This gasket is cross-referenced to a wide range of Toyota and VW-badged diesel platforms, and we deliberately left out a few applications, including certain Land Cruiser Hardtop/wagon and export sedan/van listings, where we couldn't confirm a reliable year range. Email us your VIN or engine code, and we'll check before you order.

Q: Is this a genuine Toyota part?
A: Yes. This listing is a genuine Toyota OEM part 11115-54084-F0, not an aftermarket equivalent. 

Q: What piston protrusion is this gasket designed for?
A: 0.78mm to 0.87mm. If your measured piston protrusion falls outside that range, a different gasket thickness may be required. Measure before you order if you're unsure, or contact us with your measurement.

Related Toyota Parts You May Need

• Head Bolt Set — stretch-type diesel head bolts should never be reused once torqued down.
• Timing Belt Kit — the 2L/2L-T uses a rubber timing belt; replace it while the front of the engine is already apart.
• Thermostat & Housing Gasket — inexpensive to replace while the cooling system is already open for bleeding.
  
• Glow Plugs — diesel-specific; commonly replaced during a head-off service since access is already open.

 

Common Symptoms That Point to a Head Gasket Problem

• White smoke from the exhaust, especially on cold start
• Coolant disappearing with no visible external leak
• Milky or foamy oil on the dipstick or filler cap
• Overheating that returns shortly after topping off coolant
• Bubbling or gurgling in the radiator or overflow tank with the engine running
• Rough idle or noticeable power loss under load
