Timing belt Nissan Cube AZ10 (2002–2008, engines HR15DE And HR16DE) is a critical element, the accuracy of which determines the performance of the motor. Broken marks lead to disruption of valve timing, which can lead to collision of pistons with valves (especially on engines with a high compression ratio). In this article we will look at where the timing marks are located on Cube AZ10, how to set them correctly, and what mistakes are most often made when replacing a belt.
Owners Nissan Cube often encounter problems after replacing the timing belt: the engine stalls, loses power, or does not start at all. The reason in 90% of cases is incorrectly aligned marks. We will look at the process in detail using an example 1.6 liter HR16DE, but the principles are also relevant for HR15DE. You will also learn how to check the marks without disassembling the engine and what to do if the belt has jumped 1-2 teeth.
Where are the timing marks on the Nissan Cube AZ10
On engines HR15DE/HR16DE timing marks are located on three key elements:
- 🔧 Crankshaft — the mark on the pulley (notch or dot) must coincide with the pointer on the cylinder block.
- 🔄 Camshafts — on each of the two shafts (intake and exhaust) there are grooves that align with the protrusions on the rear timing cover.
- 🔗 Oil pump - an often forgotten mark, but failure to comply with it leads to an imbalance in the operation of the lubrication system.
Feature Cube AZ10 - lack of a traditional “window” for checking crankshaft marks (as on many Nissan). Instead it is used block pointer, which is visible only when the crankshaft pulley is removed. This makes it difficult to diagnose without disassembly, but makes it easier to accurately install when replacing the belt.
The marks on the camshafts represent semicircular grooves, which should be directed straight up and coincide with the protrusions on the plastic cover. If at least one of the grooves is knocked down, the valve timing is disrupted, which leads to misfires or loss of compression.

Timing mark diagram for HR15DE and HR16DE
Below is a table with the location of the marks for both engines. Please note that on HR16DE used two-stage phase change mechanism (VTC), which adds an additional mark on the intake shaft.
| element | HR15DE (1.5 l) | HR16DE (1.6 l) |
|---|---|---|
| Crankshaft | Notch on the pulley → indicator on the block (12 o'clock) | Point on the pulley → mark on the block (12 o'clock) |
| Intake camshaft | Groove up → protrusion on cover | Groove up + VTC mark (gear) |
| Exhaust camshaft | Groove up → protrusion on cover | Groove up (same as HR15DE) |
| Oil pump | Mark on the gear → mark on the body | Mark on the gear → mark on the body |
On HR16DE pay special attention VTC mechanism (Variable Valve Timing Control). His mark is on intake shaft gear and must coincide with the groove on the body. If this mark is knocked down, the engine will operate unstably at idle, and Check Engine will give an error P0011 (wrong camshaft position).
⚠️ Attention: On HR16DE after 2006, the crankshaft mark may be shifted by 5° relative to the old version. Always check the manual for your year of manufacture!
Signs of broken timing marks on a Nissan Cube
If the timing marks are on Cube AZ10 are installed incorrectly, the engine gives clear signals. Here are the key symptoms:
- 🚗 Engine won't start or starts with difficulty (requires several attempts).
- 🔥 Treble and vibration at idle, especially after replacing the belt.
- ⚡ Power Loss — the car accelerates poorly, “does not pull” at high speeds.
- 🛑 Errors P0011, P0014, P0340 - indicate a mismatch in the phases of the camshafts and crankshaft.
- 💨 Popping sounds in the exhaust system - a sign of late ignition due to broken marks.
If at least one of these symptoms appears after replacing the timing belt, stop using immediately car. Long-term work with broken tags leads to:
- 🔩 Bend of valves (in a collision with pistons).
- 🛢️ Accelerated wear of guide bushings.
- 🔥 Engine overheating due to disruption of the combustion process.
For diagnostics without disassembling the engine, you can use strobe or diagnostic scanner (For example, Launch X431). The scanner will show the actual position of the camshafts relative to the crankshaft. If the values differ from the reference values by more than ±5°, the labels need to be reinstalled.
If the engine does not start after replacing the timing belt, try turning the crankshaft 360° (a full turn) and re-adjusting the marks. Often the belt is installed offset by one tooth, which blocks starting.
Step-by-step instructions: how to set timing marks on a Nissan Cube AZ10
To replace the timing belt and set the timing marks you will need:
- 🔧 Set of sockets and keys (10, 12, 14, 17 mm).
- 🔗 A special key for the timing belt tensioner (or a homemade analogue from an M8 bolt).
- 📏 Probe for checking belt tension (thickness 0.3–0.5 mm).
- 🔍 Flashlight for illuminating marks on camshafts.
Tag installation process:
- Remove the right front wheel and plastic fender liner to access the crankshaft pulley.
- Loosen the crankshaft pulley bolt (you will need to keep the shaft from turning through the window in the clutch housing).
- Remove the alternator belt, crankshaft pulley and upper timing cover.
- Turn the crankshaft clockwise until the mark on the pulley aligns with the pointer on the block.
- Make sure the camshaft marks are pointing up and coincide with the protrusions on the cover.
- Lock the camshafts a special retainer (or a homemade device made from a metal plate).
- Install a new timing beltstarting with the crankshaft, then pull it over the camshafts and pump.
- Adjust the belt tension using a tension roller (the deflection should be 5–7 mm when pressed with a finger).

After assembly manually turn the crankshaft 2 full turns and check the alignment of the marks again. If everything is correct, you can start the engine. If the marks are lost, repeat the procedure.
⚠️ Attention: On HR16DE with VTC system, after installing the belt, it is necessary to reset the phase adaptations using a diagnostic scanner! Without this, the engine will operate unstably.
Common mistakes when installing timing marks
Even experienced craftsmen make mistakes when replacing a timing belt with Nissan Cube AZ10. Here are the most common of them:
- 🔄 Rotate the crankshaft counterclockwise - this leads to weakening of the tensioner and displacement of the marks.
- 🔧 Ignoring the oil pump mark — without its combination, the lubrication system does not work correctly.
- 📏 Incorrect belt tension — weak tension leads to slippage, excessive tension leads to accelerated wear of the rollers.
- 🔍 Confusion with VTC labels on HR16DE — many people forget about the additional mark on the intake shaft.
- 🛠️ Using an old tension roller — it always needs to be changed along with the belt!
One of the most dangerous mistakes is installing the belt with a 1 tooth offset. On HR16DE this results in an error P0011, and on HR15DE may cause detonation due to improper ignition timing. To avoid this, always secure the camshafts before installing the belt.
Another problem - incompatibility of spare parts. For example, a timing belt from Nissan Note (with the same engine) may not be suitable due to different tooth lengths or profiles. Always use original parts or analogues with verified catalog numbers:
- 🔗 Timing belt:
Nissan 13028-4M51A(for HR16DE) or13028-4M50A(for HR15DE). - 🔄 Tension roller:
Nissan 13070-4M50A. - 🛠️ Detour video:
Nissan 13091-4M50A.
What happens if you ignore the oil pump mark?
A displacement of the oil pump mark leads to asynchronous operation of the lubrication system and timing belt. As a result, oil pressure drops at high speeds, which causes oil starvation camshafts and accelerated wear of their journals. In the worst case, this leads to shaft jamming or broken timing belt due to increased resistance.
How to check timing marks without disassembling the engine
If you suspect that the timing marks are broken, but do not want to disassemble the engine, there are several diagnostic methods:
- Strobe test:
- Connect the strobe light to the wire of the first cylinder.
- Direct the beam at the crankshaft pulley.
- When the engine is running, the mark on the pulley should “stand” motionless. If she “walks”, the phases are out of whack.
- Diagnostics with a scanner:
- Connect the scanner (for example, ELM327 or Launch).
- Check the settings
Ignition timingAndCamshaft position. - Deviation more
±5°indicates a problem with the labels.
- Compression check:
- Measure compression in all cylinders.
- Scatter more
1 barbetween the cylinders may indicate missing phases.
If you don't have a scanner, you can use using the “twisting candles” method:
- Remove all spark plugs.
- Rotate the crankshaft by hand until the piston of the 1st cylinder is at TDC (top dead center).
- Check whether the valves of the 1st cylinder are closed (they should be closed at TDC). If not, the marks are knocked down.
This method does not provide a 100% guarantee, but it helps to identify gross errors in belt installation.
If, after replacing the timing belt, the engine starts but runs unstably, in 80% of cases the problem lies in an incorrectly installed intake camshaft mark (especially on HR16DE with VTC).
Frequently asked questions about timing marks on Nissan Cube AZ10
Is it possible to drive with broken timing marks?
For a short time (before the workshop) - yes, but it’s not worth the risk. Driving for a long time with broken marks leads to:
- 🔥 Engine overheating due to disruption of the combustion process.
- 🔩 Collision of pistons with valves (on HR16DE the risk is higher due to the high compression ratio).
- 🛢️ Accelerated wear of valve guide bushings.
If the engine stalls or has difficulty starting, it is better to immediately check the marks.
How often should I change the timing belt on Cube AZ10?
Official regulations Nissan - every 100,000 km or 5 years (whichever comes first). However, in Russian conditions it is recommended to reduce the interval to 80,000 km due to:
- 🌡️ Temperature changes (in winter the belt gets dull, in summer it overheats).
- 🛣️ Bad roads (vibrations speed up the wear of the rollers).
- 🛢️ Low quality spare parts (risk of running into a fake).
What is the difference between the labels on the HR15DE and HR16DE?
Main differences:
- HR15DE:
- Simpler timing mechanism (no VTC system).
- The crankshaft mark is a notch on the pulley.
- HR16DE:
- Additional mark on the intake shaft for VTC.
- The crankshaft mark is a dot, not a notch.
- It is necessary to reset the phase adaptations after replacing the belt.
Is it possible to set timing marks without camshaft clamps?
Technically yes, but it's risky. Without clamps, the camshafts can turn when the belt is tensioned, which will lead to an error of 1-2 teeth. If there are no latches, use alternative methods:
- 🔧 Tighten the camshaft bolts firmly
100 Nm(this will create enough friction). - 📏 Check the marks 3 times before starting the engine.
On HR16DE It is almost impossible to do without clamps due to the VTC mechanism.
What errors does the ECU produce when the tags are knocked down?
Typical error codes:
P0011— incorrect position of the camshaft (intake).P0014— incorrect position of the camshaft (exhaust).P0340— camshaft position sensor error.P0300— multiple misfires (indirect sign).
If after replacing the belt the Check Engine, check the marks first, and then the sensors.
