Parts for your 2014 Subaru Exiga-Head gasket

2014 Subaru Exiga head gasket — purpose, servicing and replacement advice

Yes, the 2014 Subaru Exiga does use head gaskets. Technical references that confirm this include the Subaru Global Service Manual for the YA-series Exiga (Engine > Cylinder Head section, which details head gasket removal/installation and bolt torque/angle), Subaru’s technical information system used by dealers, and the Subaru FAST electronic parts catalogue, which lists cylinder head gaskets for the EJ20 and FB25 engines fitted to Exiga trims around 2014. As a boxer four, the Exiga’s engine has two cylinder heads, so it uses a head gasket on each side.

The head gasket’s job is to seal the combustion chambers while keeping engine oil and coolant in their proper passages. On these engines, a multi-layer steel gasket sits between the aluminium cylinder head and the block, coping with heat cycles and clamping loads while preventing cross-leaks. When it’s healthy, compression stays strong, oil stays clean, and coolant does its cooling without sneaking into places it shouldn’t.

For ongoing servicing, the best defence is heat management and clean fluids. Keep coolant changes on schedule with the correct Subaru-approved long-life coolant, ensure the radiator cap holds pressure, and fix any leaks quickly. Don’t ignore an overheating event, shut it down and sort the cause before driving again. Regular checks of coolant level, the condition of hoses, and the presence of any residue around the head/block join help spot issues early.

If replacement is on the cards, it’s a job for a competent workshop. The heads should be pressure-tested and checked for warpage, surfaces cleaned properly, and the correct torque sequence and angles followed exactly as per the Subaru workshop manual. Use genuine or high-quality MLS gaskets and replace single-use fasteners if specified. On EJ20-equipped Exiga models (timing belt), it’s smart to renew the timing belt, idlers and water pump while access is open. On FB25-equipped vehicles (timing chain), the chain is generally not routine-replacement, but guides, tensioner condition and front cover sealing should be verified. Bleeding the cooling system thoroughly after reassembly is critical to avoid hot spots or air pockets.

• Good add-ons during head work: thermostat, radiator cap, key coolant hoses, spark plugs, and fresh engine oil/filter.
• Watch for warning signs: persistent coolant loss with no obvious leaks, overheating, white exhaust vapour on warm start, milky oil, or bubbling in the overflow bottle.

Popular questions

Does the 2014 Subaru Exiga definitely have a head gasket?
Yes. Subaru’s Global Service Manual for the Exiga YA-series and the Subaru FAST parts catalogue list head gaskets for the EJ20 and FB25 engines used in 2014 Exiga variants. As a flat-four with separate heads and block, it relies on a head gasket on each bank.

How long should a head gasket last on a 2014 Exiga?
With correct coolant, proper bleeding, and no overheating, many Exiga head gaskets run well past 150,000–250,000 kilometres. Heat is the main killer, so maintaining the cooling system and driving gently if temperatures spike will help it go the distance.

What does a head gasket replacement usually cost in Australia or New Zealand?
Pricing varies with engine, machining needs, and what’s replaced while you’re in there. As a ballpark, workshops often quote roughly AUD/NZD 2,000–4,500. EJ20 (belt) jobs can trend higher if the full timing set and water pump are renewed at the same time.
