Multi-Layer Steel (MLS) Cylinder Head Gasket with 0.3mm Compressed Thickness for

The cylinder head gasket carrying Toyota genuine part number 11115-23042 (also 1111523042) seals the interface between the cylinder head and engine block on Toyota's compact petrol engine family — specifically the 2SZ-FE 1.3L and the related K3-VE 1.3L found across Toyota and Daihatsu platforms.

The 2SZ-FE is a 1,296 cc inline-4 DOHC 16-valve VVT-i engine with a 72 mm × 79.6 mm bore and stroke and a compression ratio of 11.0:1, producing approximately 86 hp (64 kW) at 6,000 rpm. The K3-VE (Daihatsu variant) shares the same 1,298 cc displacement, a compression ratio of 10.1:1, and produces around 86 hp (63 kW) with 120 Nm of torque. Both engines feature an aluminium cylinder head and aluminium cylinder block with cast-iron liners.

This gasket is constructed from multi-layer steel (MLS) — multiple precision-stamped embossed stainless steel layers with an elastomer coating on the outer surfaces. The MLS design is specifically chosen for modern compact engines to handle thermal expansion differences between components.

This Toyota 2SZ-FE cylinder head gasket 11115-23042 directly replaces the factory sealing component in the following configurations:

• Multi-Layer Steel (MLS) Construction: Precision-stamped embossed layers of stainless steel with elastomer coating for consistent clamping force through thermal cycles
• Precision 73 mm Fire Rings: Stainless steel fire rings sized to 73 mm cylinder bore for gas-tight combustion sealing
• 0.3 mm Compressed Thickness: Standard OE specification for factory 2SZ-FE and K3-VE engines
• Elastomer Coating: Heat-activated coating seals oil and coolant passages without additional sealants
• Direct OE Cross-Reference: Carries exact Toyota part number 11115-23042 with related OE and aftermarket equivalents
• IATF 16949 / ISO 9001 Certified Manufacturing: Highest automotive industry standards for component production

Procedural notes:

• Confirm correct gasket thickness before ordering (standard is 0.3 mm)
• Always replace cylinder head bolts with new genuine-spec bolts
• Check cylinder head and block surfaces for warpage
• Clean and chase all bolt holes in cylinder block
• Install gasket dry - no additional sealants required
• Install cylinder head within 15 minutes of applying seal packing
• Flush cooling system and fill with fresh coolant
• Consider professional installation for specialized tool requirements

Common failure symptoms:

• Individual packaging: Sealed in anti-static VCI bag, foam-lined carton
• Carton dimensions: Approximately 25 × 20 × 2 cm (10 × 8 × 1 inch)
• Net weight: Approximately 0.3-0.5 kg
• Master carton: 50 units per export carton (palletisable)
• Lead time: 3-7 working days for stock orders; 15-25 days for production orders above 200 pieces
• Minimum order quantity: 1 piece (sample order available)
• Shipping methods: FedEx, UPS, DHL for sample quantities; sea freight (LCL/FCL) from Shanghai, Ningbo, or Guangzhou ports
• H/S Code: 8484.10

The Toyota cylinder head gasket 11115-23042 is an OE-specification MLS (multi-layer steel) replacement for the 1.3L petrol engines in Toyota Yaris/Vitz (1999-2012), Echo, Belta, and multiple Daihatsu models. Stainless steel fire rings sized to the 73 mm cylinder bore, elastomer coating, and a compressed thickness of 0.3 mm deliver gas-tight sealing under the engine's compression ratio of up to 11.0:1.

The gasket is cross-referenced with OE numbers 11115-23041, 11115-97401, 11115-97403 and aftermarket equivalents BGA CH1558, ELRING 473.480, AJUSA 10151900.

Before ordering: The standard thickness for these 1.3L engines is 0.3 mm. If the cylinder head has been resurfaced, measure piston protrusion before ordering. For the vast majority of standard factory engines (no previous resurfacing), this gasket is the direct fit.
