Parts for your 2018 Volkswagen Amarok-Head gasket

2018 Volkswagen Amarok head gasket — what it does and when to sort it

Yes, the 2018 Volkswagen Amarok uses a head gasket. This is confirmed in Volkswagen’s erWin workshop manuals for the Amarok (MY2018) covering the 3.0 L V6 TDI EA897 engine under “Cylinder head – removing and installing,” and in the ETKA parts catalogue listing for “Gasket set, cylinder head” (group 103). Volkswagen Self‑Study Programmes for the EA897 V6 also describe the cylinder head, block and multi‑layer steel (MLS) head gasket interface. Earlier 2.0 L TDI four‑cylinder Amaroks use a conventional head gasket as well.

On the 2018 Amarok V6, the head gasket sits between the aluminium cylinder heads and the compacted‑graphite‑iron block. Its job is threefold: it seals combustion pressure in the cylinders, keeps engine oil and coolant in their own galleries without mixing, and maintains precise clearances so the engine runs efficiently and reliably. Volkswagen employs an MLS design for durability under diesel combustion pressures and thermal cycling.

While a head gasket isn’t a routine “service item,” keeping it happy is all about prevention. The big one is temperature control—avoid overheating at all costs. Stick to the correct G12/G13‑spec coolant, replace coolant on schedule, and make sure the radiator, viscous fan/electric fans, thermostat and water pump are all doing their bit. Clean oil at the right grade also helps manage heat and reduces deposit build‑up around fire rings.

• Watch for tell‑tales: unexplained coolant loss, white exhaust steam after warm‑up, pressurised hoses stone‑cold, milkiness under the oil cap, misfires on start, or a sweet smell from the exhaust.
• If any of these show up, stop driving and have it pressure‑tested and sniff‑tested. Catching issues early can save the heads and turbo.

When a head gasket does need doing on an Amarok V6, it’s a precise job. A proper workshop will follow the Volkswagen tightening sequence and torque‑angle specs, always fit new stretch bolts, check head flatness, and pressure‑test the heads. It’s smart to replace ancillary bits while access is good—intake and EGR gaskets, coolant hoses that look tired, the thermostat, and often the water pump if it’s near due. Finish with fresh oil and filter, a full coolant flush, and a correct bleed so there are no air locks. Using OEM‑quality MLS gaskets and components matters here
