2013 Mazda Premacy Head Gasket — What It Does and How to Look After It

The 2013 Mazda Premacy (Mazda5, CW series) does use a head gasket. Mazda’s factory workshop documentation for the CW platform lists cylinder head gasket removal/installation and head bolt torque procedures for both the LF-VE MZR 2.0 and the PE-VPS SKYACTIV-G 2.0 engines. See: Mazda Workshop Manual (CW, Engine Mechanical) “Cylinder Head” and “Cylinder Head Gasket Replacement” sections, plus the SKYACTIV-G service procedures describing a multi‑layer steel (MLS) gasket and torque‑to‑yield head bolts. These technical sources confirm the part is fitted to this vehicle.

On the 2013 Premacy, the head gasket’s job is simple but critical: it seals the combustion chambers while keeping engine oil and coolant in their own lanes. Sandwiched between the alloy cylinder head and the engine block, the MLS gasket copes with heat, pressure, and the different expansion rates of the metals. Whether the car’s running the LF-VE MZR 2.0 or the PE-VPS SKYACTIV-G 2.0 (market dependent), the concept’s the same — airtight combustion, no coolant-oil mingling, and stable compression so it pulls cleanly up the motorway.

It’s not a regular “service item”, but the best way to look after the head gasket is to keep the cooling system spot on. Use the correct Mazda FL22 long‑life coolant, keep the radiator and cap in good nick, and don’t ignore an overheating light. Overheating is the fast track to a cooked gasket on any alloy‑head engine. If you spot sweet‑smelling steam, white exhaust on warm start, unexplained coolant loss, pressurised hoses when cold, milky oil, or a rough idle after warm‑up, it’s time for a proper pressure and combustion‑gas test.

If replacement is needed, it’s a fair‑dinkum engine job. Best practice includes:

• Use a quality MLS gasket and always fit new torque‑to‑yield head bolts as specified in the Mazda manual.
• Have the head checked for flatness and cracks, skim only if it’s out of spec.
• Clean mating surfaces meticulously, don’t slather sealant on an MLS gasket unless the manual calls for it.
• Follow the exact bolt tightening sequence and angle stages, this matters heaps for sealing.
• Renew coolant (FL22), bleed the system properly, and consider a fresh thermostat and any tired hoses while you’re there.

Because timing components, fuel, and emissions gear need to come off, many owners leave this to a reputable workshop. Done right, the new gasket will be set for many more kilometres of easy motoring.

Popular questions about 2013 Mazda Premacy head gaskets

Does the 2013 Premacy definitely have a head gasket?
Yes. Mazda’s CW workshop manual for both the LF‑VE MZR 2.0 and PE‑VPS SKYACTIV‑G 2.0 engines includes cylinder head gasket replacement and head bolt torque procedures, confirming an MLS head gasket and single‑use (torque‑to‑yield) bolts are specified.

What usually causes head gasket failure on these?
Overheating is the big one — low coolant, an ageing radiator, a dud thermostat, or a non‑functioning cooling fan can push temps up and stress the alloy head. Keeping to proper coolant (FL22), fixing leaks early, and ensuring good airflow through the radiator massively reduces the risk.

Can a competent DIYer replace it at home?
It’s doable for an experienced DIYer with the right tools, space, and the Mazda workshop procedure, but it’s not a quick shed job. Expect precise timing alignment, strict torque/angle sequences, and a lot of refitting and bleeding. Many owners opt for a specialist to guarantee sealing and reliability.
