Parts for your 2016 Mitsubishi Outlander-Head gasket

2016 Mitsubishi Outlander head gasket: what it does, when to replace, and how to look after it

Yes, a head gasket is used on the 2016 Mitsubishi Outlander. Mitsubishi’s own technical sources confirm it: the Outlander GF/GL Workshop Manual includes cylinder head gasket removal/installation and head-bolt torque procedures for the 2.0L and 2.4L MIVEC petrols, the 3.0L V6, the 2.2L turbo-diesel, and the PHEV’s 2.0L engine. The Mitsubishi Electronic Parts Catalogue (ASA/EPC) also lists head gaskets as service parts for these engines. So, for any 2016 Outlander variant, the head gasket is very much relevant.

In an Outlander, the head gasket sits between the engine block and the cylinder head, sealing three critical things at once: the combustion chambers, the coolant passages, and the engine oil galleries. Its job is to keep compression where it belongs, stop coolant and oil from mixing, and prevent leaks to the outside world. Modern Outlanders use multi-layer steel (MLS) gaskets designed to cope with thermal cycling and high combustion pressures, which is why correct surface prep and bolt torque are essential during any repair.

There’s no scheduled replacement interval for a head gasket, it’s a fix-as-needed item. Typical warning signs include unexplained coolant loss, overheating under load, white exhaust steam once warm, rough cold starts, bubbles in the radiator/expansion bottle, or milky contamination under the oil filler cap. If that’s happening under the bonnet, it’s time for testing (cooling system pressure test, chemical block test, and compression/leak-down checks).

Replacement on a 2016 Outlander is a proper workshop job. The cylinder head must come off, mating surfaces checked for flatness, and the correct torque sequence followed—often with new torque-to-yield head bolts, as specified in the factory manual. The mechanic will typically:

• Inspect and machine the cylinder head if required, and check the block deck for warpage.
• Fit an OEM-quality MLS gasket dry (unless the manual calls for a specific sealant).
• Renew coolant, thermostat, and any tired hoses while they’re in there.

Good preventative care helps the gasket live a long life: keep the cooling system in top nick, use the correct spec coolant, resolve overheating straight away, and stick to the recommended service intervals. If a gasket does fail, expect labour to be the main cost driver, with pricing varying by engine (petrol, diesel, or V6) and whether machining is needed.

Popular questions about 2016 Mitsubishi Outlander head gaskets

What are the common signs of a blown head gasket on a 2016 Outlander?
Look for persistent overheating, loss of coolant with no visible leak, white steam from the exhaust after warm-up, a sweet smell from the exhaust, rough running at start-up, or milky residue under the oil cap. A cooling system pressure test and a chemical test for combustion gases in the coolant can confirm the diagnosis.

Do the head bolts need replacing when doing the gasket?
Most 2016 Outlander engines use torque-to-yield head bolts that stretch once torqued. The workshop manual generally specifies replacing them rather than reusing. Always follow the correct torque and angle sequence—skipping this risks repeat failure.

How much does a head gasket replacement typically cost in Australia or New Zealand?
It varies with engine type and machine work, but a ballpark for professional repair is often in the AUD/NZD $1,500–$3,500 range. Diesel and V6 variants can sit toward the upper end. A precise quote needs an inspection to see if the cylinder head requires machining and what ancillary parts are due.
