Parts for your 2013 Nissan Pulsar-Head gasket

2013 Nissan Pulsar head-gasket — what it does and when to replace it

The 2013 Nissan Pulsar uses a conventional cylinder head-gasket. Both the B17 sedan (typically MR18DE 1.8 petrol) and the C12 hatch (MR18DE or MR16DDT 1.6 turbo) are alloy head/allow block designs sealed with a multi-layer steel (MLS) head-gasket. This is confirmed in Nissan Factory Service Manuals for B17/C12 in the Engine Mechanical “Cylinder Head” section, and by parts listings in Nissan FAST/ASA and major gasket catalogues (Permaseal, Victor Reinz, Fel‑Pro), all of which specify a head-gasket for these engines.

The head-gasket’s job is simple but critical: it seals combustion pressure between the head and block, and keeps engine oil and coolant in their own passages so they don’t mix. On the Pulsar’s MR-series engines, the MLS gasket copes with heat cycles and boost (for MR16DDT) while maintaining clamp with torque‑to‑yield head bolts.

It’s not a scheduled service item, so the best “maintenance” is looking after the cooling system to avoid overheating—the number-one killer of head-gaskets. Under the bonnet that means fresh Nissan‑spec long‑life coolant at the right mix, a healthy radiator cap, clean radiator and condenser fins, fans that kick in, and a thermostat that opens on cue. Regular oil changes also help keep internal temps and deposits in check.

• Typical warning signs owners watch for:
  • Unexplained coolant loss, pressurised hoses after cool-down, or bubbles in the overflow
  • Sweet exhaust smell, white steam after warm-up, or milky contamination on the oil cap/dipstick
  • Misfire on cold start, overheating under load, or a rising temp gauge

If replacement is needed on a 2013 Pulsar, a workshop will usually compression/leak‑down test first, then perform a cooling‑system pressure or chemical block test. During the job they’ll check the head and block for flatness and cracks, prepare surfaces to the finish spec in the manual (critical for MLS), fit a new OEM‑quality gasket, and always use new head bolts (they’re one‑time‑use). Correct torque‑angle sequences from the FSM are non‑negotiable. It’s smart to renew the thermostat, radiator cap and any tired hoses, then refill with the correct blue long‑life coolant and bleed the system properly. After the first heat cycles, a quick recheck for leaks and coolant level settles the job. Done right, an MLS gasket on these engines will go the distance for many years and kilometres.

Popular questions about 2013 Nissan Pulsar head-gaskets

What are the common symptoms of a blown head-gasket on a 2013 Pulsar?
Owners most often notice persistent coolant loss with no external leak, overheating under load, or white steam from the exhaust once warm. A misfire on cold start and a pressurised upper radiator hose after sitting overnight can also point to combustion gases in the cooling system.

A quick cooling‑system pressure test and a chemical block test (for hydrocarbons in coolant) are typical first checks before pulling anything apart.

How much does a Pulsar head-gasket replacement usually cost in AU/NZ?
Pricing varies with engine (MR18DE vs MR16DDT), machine work, and what else is replaced. As a ballpark, professional repairs can range from mid‑to‑high four figures AUD/NZD when machining, bolts, fluids, thermostat and incidentals are included. Getting an itemised quote that specifies OEM‑quality MLS gaskets and new head bolts is the best approach.

Can it be driven with a suspected head-gasket issue?
It’s not recommended. Even short trips can escalate damage by overheating, warping the head, or washing bearings with coolant‑contaminated oil. If symptoms appear, keep trips short, avoid boost/load, and book a test promptly to prevent a small issue turning into a full engine rebuild.
