Replacing the cylinder head gasket on a Nissan Cube: instructions with photos, errors and tips

Cylinder head gasket (cylinder head) Nissan Cube - a detail that often becomes a source of headaches for owners. Its breakdown leads to engine overheating, mixing of oil with antifreeze and even water hammer. In this article we will look at how replace the cylinder head gasket yourself on Cube (including models K12 And K13 with engines HR15DE And HR16DE), without contacting the service. You will learn about the symptoms of malfunction, the necessary tools, the step-by-step disassembly and assembly process, as well as critical errors that can ruin the engine if installed incorrectly.

Feature Nissan Cube - compact engine compartment, which complicates access to the cylinder head bolts. But with the right preparation and patience, the task is doable even in a garage. We will dwell in detail on points that are often missed in standard instructions: how crimp the gasket correctly, which bolts require replacement, and why sealant cannot be used on some models. If you notice white smoke from the exhaust pipe, oil in the expansion tank, or constant “eating” of antifreeze, this article is for you.

Signs of a broken cylinder head gasket on a Nissan Cube

The cylinder head gasket does not fail instantly - it is usually a gradual process that can be detected by indirect signs. On Nissan Cube with engines HR series The most common symptoms are:

• 🔥 Engine overheating for no apparent reason (the fan is working, the thermostat is working, but the temperature is creeping up). This is due to exhaust gases entering the cooling system.
• 💨 White thick smoke from the exhaust pipe, especially when starting cold. A sign of antifreeze getting into the combustion chambers.
• 🛢️ "Mayonnaise" under the oil filler cap or on the dipstick. An emulsion is formed when oil is mixed with coolant.
• 🚗 Antifreeze level drop no external leaks. The fluid goes into the cylinders or crankcase.
• 🔧 Unstable engine operation (trips, misfires) due to compression failure.

On Cube K13 with HR16DE One more specific sign is often found: bubbles in the expansion tank with the engine running. This indicates a breakthrough of exhaust gases into the cooling system through a damaged gasket. If you ignore the problem, the consequences can be critical: from corrosion of liners to water hammer and major repairs.

⚠️ Attention: On Nissan Cube with an automatic transmission, a breakdown of the cylinder head gasket can simulate an automatic transmission malfunction (jerking, kicking). This is due to the fact that the engine control unit (ECU) corrects the operation of the transmission in case of unstable compression. Don't rush to change the box - check the gasket first!

Tools and materials for replacement

To replace the cylinder head gasket with Nissan Cube you will need a specialized tool. Do not try to make do with “improvised means” - this can lead to the bolts breaking or improper tightening. Here's the full list:

Category	Name	Notes
Main tool	Torque wrench	Required! The tightening torque of the cylinder head bolts is 100–120 Nm in 3 stages.
Specialized tool	Camshaft puller	Needed to secure the shafts when removing sprockets.
Consumables	Cylinder head gasket Nissan (item: 11044-JM00A)	Original or high-quality analogues: Elring, Ajusa.
Additionally	Sealant Loctite 574 (or equivalent)	Only for oil channels! Do not apply to surfaces in contact with antifreeze.
Other	Socket heads 10 mm, 12 mm, 14 mm	Extended heads for hard to reach bolts.

Also prepare:

• 🔧 Screwdriver set (including JIS for Japanese bolts).
• 🧴 Carburetor cleaner or WD-40 to remove old sealant.
• 📦 Plastic bags and a marker for marking disassembled parts.
• 🔦 Bright LED lamp - in the engine compartment Cube It's dark even during the day.

⚠️ Attention: Cylinder head bolts on HR15DE/HR16DE - disposable! They must be replaced with new ones (article: 11026-JM00A). Reusing old bolts will result in uneven tightening and repeated gasket failure.

Preparation for replacement: draining fluids and removing the attachment

Before getting to the cylinder head, it is necessary to drain all technical fluids and dismantle interfering components. On Nissan Cube this process takes 3–4 hours for beginners and 1–1.5 hours for experienced craftsmen. Follow the algorithm:

1. Drain the antifreeze. Remove the cap on the radiator (lower right corner) and cylinder block (rear of the engine, under the manifold). Use a container with a volume of at least 8 liters.
2. Remove the air filter and throttle assembly. Disconnect all connectors (even those that seem unnecessary) and mark them with tape.
3. Remove the exhaust manifold. On HR16DE it is attached with 4 bolts to the cylinder head and 2 nuts to the exhaust pipe. Bolts often stick - use penetrating lubricant in advance.
4. Remove the timing belt. To do this, fix the crankshaft and camshafts (use a puller or homemade clamps made of metal plates).

Pay special attention timing marks. On Nissan Cube with HR16DE they must match:

• 🔄 Crankshaft (mark on the pulley and block).
• 🔄 Camshafts (two marks on the sprockets and cylinder head).

If the marks are off, after assembly the engine will not start or will run intermittently. Take a photo of their position before removing the belt!

Removing the cylinder head: step-by-step instructions

Now we move on to the most important stage - dismantling the cylinder head. On Nissan Cube this process has its own nuances due to the compact engine compartment. Follow the instructions:

1. Disconnect all pipes and connectors. On HR15DE/HR16DE this:
   • 🔌 Coolant temperature sensor.
   • 🔌 Knock sensor (mounted under the intake manifold).
   • 🔌 Ignition coil connector.
2. Remove the camshafts. To do this:
   • Unscrew the bearing caps (sequence: from edges to center!).
   • Carefully remove the shafts without damaging the seals.

Unscrew the cylinder head bolts. Use a socket 12 mm and lever. Important: loosen the bolts in the reverse tightening sequence (see diagram below).

After unscrewing the bolts, remove the block head. It may “stick” - don’t hit it with a hammer! Use a block of wood and even force. If the head does not budge, check that all bolts are unscrewed (at HR16DE there are 10 of them).

Inspect the surfaces of the block and head for:

• 🔍 Contortions (check with a ruler and feeler gauge - tolerance is no more than 0.05 mm).
• 🔍 Corrosion (especially in coolant passage areas).
• 🔍 Remnants of the old gasket - they must be completely removed with a scraper.

What to do if the block head is bent?

If the curvature exceeds 0.05 mm, the head must be ground by machine. On Nissan Cube The maximum permissible metal removal is 0.2 mm. After grinding, check the height of the combustion chambers: if it is less than 9.5 mm, the head will have to be replaced.

Installing a new gasket and assembling

This is the most critical stage. Errors here lead to repeated gasket failure or damage to the cylinder head. Follow the algorithm:

1. Clean surfaces. Use carburetor cleaner and a plastic scraper. Metal brushes are prohibited - they scratch the aluminum!
2. Check the new gasket. There should be marks on it TOP (top) and FRONT (before). On Cube gasket with article number is installed 11044-JM00A (for HR15DE/HR16DE).
3. Apply sealant. Only for oil channels (see diagram in the instructions for the gasket)! Apply sealant to water channels it's impossible — it will clog the cooling system.
4. Install the gasket. She should lie down without effort. If you have to press, check the cleanliness of the surfaces.

Now let's move on to tightening cylinder head bolts. This is done in 3 stages with intermediate exposure:

1. 1st stage: 40–50 Nm (pre-tightening).
2. 2nd stage: 70–80 Nm (10 minutes after the 1st stage).
3. 3rd stage: 100–120 Nm (in another 10–15 minutes).

The tightening pattern is from the center to the edges (see picture). Use a torque wrench - “by eye” is unacceptable here!

Common mistakes and how to avoid them

Even experienced craftsmen sometimes make mistakes when replacing the cylinder head gasket with Nissan Cube. Here are the most common:

• 🔧 Using old bolts. They stretch out when tightened and do not provide the required force. Result: gasket breakdown after 1–2 thousand km.
• 🔥 Failure to comply with the tightening torque. Weak tightening leads to gas breakthrough, excessive tightening leads to deformation of the head.
• 💧 Sealant getting into oil channels. This causes clogged oil lines and oil starvation.
• 🔄 Incorrect installation of timing marks. The engine will not start or will run intermittently.
• 🚗 Forgotten sensor connectors. For example, an unconnected knock sensor will cause an error P0327.

Another typical problem is head misalignment when tightening. To avoid this, use a criss-cross pattern and make sure the head sits evenly on the block. If after assembly the engine misfires or overheats, check:

• 🔍 Compression in the cylinders (should be 12–14 bar, spread no more than 1 bar).
• 🔍 Antifreeze leaks (especially at the junction of the cylinder head and the block).
• 🔍 Error codes (P0300 - misfires, P0171 - lean mixture due to air leaks).

First start after replacement: what to check

After assembly, do not rush to start the engine. First:

1. Check oil and antifreeze level (must be at maximum).
2. Make sure that all connectors are connected and the pipes are not pinched.
3. Crank the engine with the starter (without starting) for 5–10 seconds to distribute the oil throughout the system.

On first launch:

• 🔍 Follow oil pressure (the lights on the tidy should go out after 2-3 seconds).
• 🔍 Check it out temperature - it should not rise above 90°C in 5 minutes.
• 🔍 Inspect the cylinder head joint for antifreeze or oil leaks.

In the first 500 km after replacing the gasket:

• 🚗 Avoid high speed (not higher than 3000 rpm).
• 🚗 Control antifreeze level (hidden leaks are possible).
• 🚗 Follow exhaust color - white smoke indicates antifreeze has entered the cylinders.

If everything is in order, after 1000 km you can carry out control check: measure compression and inspect the spark plugs (there should be no oil deposits on them).

What should I do if after replacing the gasket the engine stalls?

Troubleshooting after replacing the cylinder head gasket with Nissan Cube may be caused by:

• 🔧 Incorrect tightening of bolts (check the torque with a torque wrench).
• 🔥 Breaking the new gasket (inspect it for damage).
• 💡 Malfunction of ignition coils (swap them - if the cylinder has changed, the coil is to blame).
• 🛢️ Antifreeze entering the cylinders (you need to blow air or replace the spark plugs).

Check the compression first. If in one cylinder it is lower by 30% or more, the gasket is broken again.

Is it possible to drive with a broken cylinder head gasket?

Briefly - no. Even a small breakdown leads to:

• 🔥 Engine overheating and risk water hammer (if antifreeze gets into the cylinder while the engine is running).
• 🛢️ Mixing oil and antifreeze, which leads to scoring on the cylinder walls.
• 💨 Loss of power and increased fuel consumption.

If the breakdown is small (for example, only an external oil leak), you can carefully get to the garage, but no more than 50–100 km. Watch the temperature!

How much does it cost to replace a cylinder head gasket on a Nissan Cube at a service center?

The cost of work in the service depends on the region and level of the service station:

• 🔧 Self-replacement: 3–5 thousand rubles. (cost of gasket + bolts + sealant).
• 🔧 Service replacement:
  • In the regions: 8–12 thousand rubles. (without spare parts).
  • In Moscow/St. Petersburg: 12–18 thousand rubles.

If head grinding is required, add another 3–5 thousand rubles. Spare parts (original gasket + bolts) will cost 4–6 thousand rubles.

How often do you need to change the cylinder head gasket on a Nissan Cube?

The cylinder head gasket is not a consumable, and during normal use it serves 150–200 thousand km. However, its replacement is required when:

• 🔧 Engine overhaul.
• 🔥 Engine overheating (even once!).
• 💧 Oil or antifreeze leaks at the cylinder head joint.
• 🛠️ Removing the cylinder head (for example, to replace valves).

On Nissan Cube with a mileage of more than 150 thousand km, it is recommended to check the gasket at every maintenance (inspect the joint for leaks and monitor the color of the exhaust).

Is it possible to use a non-original cylinder head gasket?

Yes, but with reservations. Good analogues:

• 🔧 Elring (item: 763.570) - German quality, often better than the original.
• 🔧 Ajusa (item: 10144200) is a Spanish brand popular in Europe.
• 🔧 Nipparts (item: N5110515) is a Japanese analogue, close to the original.

Avoid cheap, unbranded pads - they often become tanned after the first heating. Also check that the kit includes metal stops (they prevent the gasket from being squeezed out).
