Parts for your 2022 Mitsubishi Eclipse cross-Head gasket

2022 Mitsubishi Eclipse Cross head gasket: what it is, why it matters, and when to act

Based on technical sources, a head gasket is absolutely relevant and fitted to the 2022 Mitsubishi Eclipse Cross. The Mitsubishi Motors Workshop Manual for Eclipse Cross (GK/GL series, Engine Mechanical sections for the 1.5‑litre turbo 4B40 and the 2.4‑litre PHEV engine) specifies a cylinder head gasket and torque‑to‑yield head bolts. The Mitsubishi ASA/OEM parts catalogue likewise lists a “gasket, cylinder head” for these engines. So yes, this model runs a conventional multi‑layer steel (MLS) head gasket between the cylinder head and block.

In the Eclipse Cross, the head gasket seals three critical zones at once: the high‑pressure combustion chambers, the engine oil galleries, and the coolant passages. On the 1.5T direct‑injection engine (and the 2.4 PHEV petrol engine), that MLS gasket copes with turbo boost, temperature swings, and the constant expansion and contraction under the bonnet. When it’s healthy, there’s solid compression, clean oil, and stable coolant temps. When it’s not, owners may see overheating, rough running, or contaminated fluids.

The head gasket isn’t a scheduled service item, it’s replaced only if there are symptoms or if the head is removed for other work. Sensible maintenance greatly reduces the risk of trouble. Keeping the cooling system spot‑on is the big one—fresh coolant to the correct Mitsubishi spec, a sound radiator and cap, a working thermostat and fans, and never driving on an overheat. Quality fuel and timely oil changes also help by minimising knock and hotspots that can stress the gasket.

• Watch for warning signs: unexplained coolant loss, sweet‑smelling white exhaust, pressurised hoses from cold, milky oil, overheating, or a persistent misfire after start‑up.
• If a gasket job is needed, a proper fix includes: confirming with chemical/block tests, checking head and block flatness, cleaning decks meticulously, fitting an OEM‑quality MLS gasket, replacing torque‑to‑yield head bolts, and following the exact torque/angle sequence from the workshop manual.
• It’s smart to renew related bits while in there—thermostat, radiator cap, and any tired hoses—so the repair lasts.

A well‑maintained Eclipse Cross should see the head gasket last the life of the engine. If any of the tell‑tales appear, a quick chat with a Mitsubishi dealer or a trusted independent in Australia or New Zealand can save a lot of grief (and coin) down the track.

FAQ

Does the 2022 Mitsubishi Eclipse Cross actually have a head gasket?
Yes. The Mitsubishi Motors Workshop Manual for the Eclipse Cross (GK/GL) and the Mitsubishi ASA parts catalogue both list a cylinder head gasket for the 1.5‑litre turbo petrol and the 2.4‑litre PHEV engines, along with torque‑to‑yield head bolts. It’s a standard MLS design used to seal combustion, oil, and coolant passages.

What are common signs the head gasket might be failing?
Tell‑tales include overheating, unexplained coolant loss, white steam from the exhaust, foamy or milky oil, hard upper radiator hoses from cold, or a lingering misfire on start‑up. Any of these warrant cooling‑system checks and a block test before the situation escalates.

Should head bolts be replaced during a head gasket job on this model?
Yes. Both the 1.5T and 2.4 PHEV engines use torque‑to‑yield head bolts. Best practice is to replace them, then follow the exact torque/angle sequence from the workshop manual. Skipping new bolts or the correct procedure risks an early repeat of the job.
