2014 Subaru XV head gasket: what it does and how to look after it

Yes, the 2014 Subaru XV does use a head gasket. Technical sources that spell this out include the Subaru Factory Service Manual (FSM) for the 2014 Impreza/XV with the FB20 engine (Engine > Cylinder Head section lists the cylinder head gasket and torque procedure), and Subaru’s genuine parts catalog (often referenced via Subaru FAST), which lists specific cylinder head gasket part numbers for the FB20. Those documents confirm the gasket is a required sealing component between each cylinder head and the aluminium block on this boxer-four.

On the XV’s 2.0‑litre FB20, the head gasket is a multi‑layer steel (MLS) seal that keeps three things where they belong: high‑pressure combustion in the cylinders, coolant in the water jackets, and oil in the lubrication galleries. Because the engine is horizontally opposed, there are two heads and two gaskets, one per bank.

It’s not a routine service item, but it absolutely benefits from good maintenance habits. Using the correct Subaru coolant (many 2014 models shipped with long‑life “blue” Super Coolant) and sticking to the factory change intervals helps protect the gasket and the alloy mating surfaces. Keeping the cooling system free of air, using the correct radiator cap and thermostat, and fixing leaks early all reduce thermal stress that can shorten gasket life.

If a replacement is needed, it’s a heads‑off job and best done by a Subaru‑savvy workshop. Both sides are typically inspected and, if one gasket has failed, many techs recommend replacing the pair. The cylinder head faces should be checked and lightly machined if out of spec, surfaces meticulously cleaned, and new MLS gaskets fitted. Follow the FSM torque‑and‑angle sequence for the FB20’s head bolts, many workshops fit new bolts or verify re‑use against Subaru’s length/spec guidance. Expect downtime of at least a full day, longer if machining or parts delays crop up.

• Tell‑tale signs: unexplained coolant loss, overheating on climbs, bubbles in the overflow, sweet‑smelling exhaust, milky residue under the oil cap, rough cold starts, or a pressurised upper radiator hose from cold.
• Preventive tips: keep the cooling system healthy, don’t ignore small leaks, and use genuine or high‑quality equivalent parts and the correct coolant mix.

Popular questions

Do 2014 Subaru XVs commonly have head gasket problems?
Compared with older EJ‑series engines, the FB20 in the 2014 XV has a better MLS gasket design and generally fares well when cooling systems are maintained. Failures can happen with age, overheating, or poor coolant care, but widespread issues are far less common than on early‑2000s models.

What are the symptoms of a failing head gasket on an XV?
Drivers often notice persistent coolant loss without obvious leaks, overheating under load, bubbles in the expansion tank, exhaust that smells sweet, milky contamination in oil, or a misfire on cold start. A workshop can confirm with a chemical block test, pressure test, and cylinder leak‑down.

How much does a head gasket job cost in Australia or New Zealand?
Prices vary with labour rates, parts choice, and whether machining is needed. As a ballpark, many owners in Australia see totals in the AU$2.5k–$5k range, and in New Zealand roughly NZ$3k–$6k. A proper quote will hinge on inspection findings and any “while you’re there” items like hoses, water pump, or timing components.
