Toyota 1111522050 — Cylinder Head Gasket
Overview
Cylinder head gasket Toyota 1111522050 seals the interface between the engine cylinder block and cylinder head, preventing combustion gas leakage, coolant loss, and internal oil contamination. Manufactured from multi-layer steel (MLS) with a high-temperature elastomer surface coating, this component withstands extreme thermal cycles, cylinder pressure peaks, and chemical degradation from engine fluids. Key technical specifications include a 1.0 mm nominal thickness, 79.5 mm cylinder bore diameter, integrated stopper fire rings, and precision-stamped oil and coolant passage openings. Original equipment part number Toyota 1111522050 corresponds to cross-reference 11115-22050 and directly replaces older OEM revision 11115-22040, matching factory cylinder head mating surface tolerances and head bolt hole locations.
Fits vehicle models powered by the 1.8-litre 1ZZ-FE four-cylinder petrol engine, including Toyota Corolla E120/E130 (2001–2007), Toyota Celica ZZT230 (1999–2005), Toyota Avensis T220/T250 (2000–2008), Toyota MR2 Spyder ZZW30 (1999–2007), Toyota Matrix ZZE130 (2002–2008), and Toyota Wish ZNE10 (2003–2009). Replacement is necessary when experiencing gasket fire ring blowout, oil-coolant cross-contamination, white exhaust smoke emissions, aeration in the cooling expansion tank, compression drop across adjacent cylinders, engine overheating, or during any major engine rebuild requiring cylinder head removal.
