Chevrolet Onix 1.0T L3 Cylinder Head Assembly – Onix / Onix Plus / Tracker / Montana

This Chevrolet Onix 1.0T L3 cylinder head assembly is a brand new, factory-fresh replacement for the turbocharged three-cylinder Ecotec petrol engine used in the Onix, Onix Plus, Tracker and Montana ranges from 2020 onward. It is supplied with valves and camshafts fitted according to your confirmed stock configuration — the E22 turbo family houses the camshafts in a carrier assembly, and supplier configurations vary, so confirm your stock physically before ordering.

What’s Included – Fitted to the Head (Confirmed Configuration Only)

• Complete aluminium cylinder head casting — pressure-tested and flatness-checked
• 12 valves — intake and exhaust, heat-resistant (4 per cylinder) — if your stock is a complete assembly
• Valve springs, spring seats and retainers — if valves are fitted
• Valve stem seals and valve guides — fitted
• DOHC camshafts — intake and exhaust — only if your stock is a complete assembly that includes the camshaft carrier; confirm before ordering
• Camshaft bearing caps / carrier — torqued to specification — if camshafts are fitted
• Core plugs and oil gallery plugs — installed

What you transfer from your original head: camshaft carrier and valve cover assembly (if not included in your stock), hydraulic lifters, timing belt kit (wet belt, tensioner and idler), head bolts (always fit new stretch bolts), head gasket and remaining gaskets, direct fuel injectors, spark plugs, ignition coils, intake manifold, exhaust manifold, turbocharger and any sensors or brackets mounted to the head.

Vehicle Compatibility — Model and Engine Code Detail

The Short Description lists the basic model range. The fitment below is the model and trim-level detail needed to confirm the correct casting before ordering. The E22 turbo head is shared across the Onix, Onix Plus, Tracker and Montana platforms, but combustion chamber volume and valve material differ from the naturally aspirated E22-100 — never fit a non-turbo head to a turbo engine or vice versa.

• Chevrolet Onix 1.0 Turbo (2020–2025) — LT, LTZ, Premier and RS trims, manual and automatic
• Chevrolet Onix Plus 1.0 Turbo (2020–2025) — LT, LTZ, Premier trims, manual and automatic
• Chevrolet Tracker 1.0 Turbo (2020–2025) — LT, LTZ, Premier trims, automatic
• Chevrolet Montana 1.0 Turbo (select years) — confirm engine code before ordering

This cylinder head is specific to the E22-E100 turbocharged 1.0L three-cylinder petrol engine. It is NOT interchangeable with the naturally aspirated E22-100 head, the 1.2L three-cylinder engine, or any four-cylinder engine in the Chevrolet range.
