Replacing the timing belt with Nissan Cube - a procedure that requires not only accuracy, but also exact adherence to the marks of the gas distribution mechanism. An error in setting even one tooth can lead to serious consequences: from loss of power to collision of pistons with valves and major engine overhaul. In this article we will look at where the timing marks are located on Cube different generations, how to set them correctly, and what to look for when replacing a belt or chain.
Feature Nissan Cube - a compact engine with a unique layout, which complicates access to the timing mechanism. Depending on the year of manufacture and type of motor (for example, HR15DE or KR15DE) the marking scheme may differ. We will look at both options in detail, and also give recommendations on diagnosing belt wear and signs of belt failure.
What engines were installed on the Nissan Cube and their timing features
Nissan Cube was produced from 1998 to 2019, and during this time several types of engines were installed on it. The most common:
- 🔧 HR15DE (1.5 l, 109 hp) - naturally aspirated gasoline with timing belt drive. Installed on models from 2008 to 2014. Feature: the marks on the crankshaft and camshaft pulley are visually poorly contrasted, which makes them difficult to find.
- 🔧 KR15DE (1.5 l, 110 hp) - modification with the system Dual Injector. The timing drive is also belt driven, but the marks are clearer. Used in Cube third generation (2014–2019).
- 🔧 CG13DE (1.3 l, 87 hp) - an outdated engine, found in early versions (1998–2002). Here the timing chain drive is used, but the life of the chain often does not exceed 150–180 thousand km.
Important: on Cube with motors HR/KR It is recommended to change the timing belt every 90–100 thousand km or once every 5 years (whichever comes first). Neglecting this rule can result in belt breakage and valve bending - HR15DE And KR15DE are intervention engines (when a break occurs, the pistons hit the valves).
Chain drive on CG13DE less critical to replacement timing, but requires monitoring of the tensioner and damper. If extraneous noise appears (a rattling sound on a cold engine), the circuit must be checked immediately.

Where are the timing marks on the Nissan Cube: diagram and photo
Timing marks on Nissan Cube located on three key elements:
- Crankshaft pulley — a mark in the form of a dot or marks, combined with the pointer on the oil pump.
- Camshaft pulleys (inlet and outlet) - marks in the form of protrusions or holes that should look straight up when in the correct position.
- Rear timing cover - often has additional indicators for visual control.
Below is the diagram for the motor HR15DE (similar to KR15DE):
| element | Label | Combination with |
|---|---|---|
| Crankshaft | Point on the pulley | Protrusion on oil pump (bottom) |
| Camshaft (intake) | Protrusion on gear | Hole in the back cover (up) |
| Camshaft (exhaust) | Hole on gear | Index on the cover (up) |
| Tension roller | — | Arrow on the body (to check tension) |
In practice, the marks on Cube often difficult to see due to dirt or corrosion. Before work, clean the pulleys and timing cover with solvent, and for better visibility, use a flashlight or marker to highlight the marks.
What do the marks on the camshafts look like?
On the intake camshaft, the mark is a small protrusion (about 2–3 mm), and on the exhaust camshaft, it is a round hole with a diameter of 5 mm. Both should be directed straight up and coincide with the grooves on the rear timing cover.
Step-by-step instructions: how to set timing marks on a Nissan Cube
To work you will need:
- 🔧 Set of sockets and ratchet wrench (10, 12, 14 mm).
- 🔧 A special key for the tension roller (or pliers with thin jaws).
- 🔧 Jack and supports (for lifting the front of the car).
- 🔧 Marker and flashlight.
Algorithm of actions:
- Preparation: Remove the right front wheel and plastic mudguard. Disconnect the negative terminal of the battery. Remove the alternator and air conditioning compressor belt.
- Removing the timing cover: Unscrew the 6 bolts securing the top and bottom covers (10 mm socket). Be careful - there may be residual sealant under the lid.
- Checking labels: Rotate the crankshaft clockwise (by the pulley bolt, 19 mm socket) until the mark on the crankshaft aligns with the pointer on the oil pump. Make sure the camshaft marks are facing up.
- Fixing camshafts: If the marks do not match, loosen the belt tensioner and carefully tighten the camshafts to the correct position. To fix, use a special tool or homemade devices made from metal plates.
- Belt replacement: Remove the old belt, check the condition of the rollers and pump. Install the new belt starting at the crankshaft, then tension it through the tensioner pulley (clockwise).
- Tension check: After installation, rotate the crankshaft 2 turns and check the alignment of the marks. The belt tension should be such that it can be rotated 90° between the camshaft pulleys.
☑️ Pre-assembly checklist
⚠️ Attention: On motors HR15DE/KR15DE After replacing the timing belt, be sure to reset the ECU errors using a diagnostic scanner. Otherwise it may catch fire Check Engine due to a mismatch between the signals from the crankshaft and camshaft sensors.
Common mistakes when replacing a timing belt and how to avoid them
Even experienced craftsmen sometimes make mistakes that lead to serious damage. Let's look at the most common ones:
- ❌ Misalignment of marks on camshafts. If the crankshaft marks match, but the camshafts are turned incorrectly, the engine will stall or will not start. Always check the position both camshafts!
- ❌ Belt that is too tight or too tight. Excessive tension accelerates wear on the rollers and belt, while weak tension leads to slippage and phase failure. Use a torque wrench for the tensioner (torque: 40–45 Nm).
- ❌ Ignoring pump status. On Nissan Cube The pump often fails at the same time as the timing belt. If you do not replace it in advance, after 20–30 thousand km antifreeze may leak into the oil sump.
- ❌ Damage to the crankshaft position sensor. When removing the crankshaft pulley, it is easy to hit the sensor, which will lead to an error
P0335. Before work, disconnect the sensor connector.
To avoid problems, follow the rule: "Three checks":
- Check the labels to removing the old belt.
- Check the labels after installing a new belt (before cranking).
- Check the labels after two full revolutions of the crankshaft.
If after replacing the timing belt the engine does not start or runs erratically, do not try to “get used to” the problem. Remove the timing cover and check the marks again - most likely, one of the camshafts has shifted by 1-2 teeth.
Signs of timing belt wear: when is it time to change
Timing belt on Nissan Cube wears out gradually, and its condition can be tracked by indirect signs:
- 🚗 ticking sound from under the hood at idle speed - indicates wear on the belt teeth or rollers.
- 🚗 Engine vibration at low speeds (1000–1500 rpm) - valve timing failure is possible.
- 🚗 Power dips when accelerating, the belt slips and the valves open at the wrong moment.
- 🚗 Oil leak from the timing cover side - often accompanied by oil getting on the belt, which accelerates its destruction.
Visually inspect the belt through the inspection window (if equipped) or by removing the top cover. Critical defects:
- Cracks on the inside of the belt.
- Detachment of rubber from the cord base.
- Oily or traces of antifreeze (indicates a pump leak).
- Wear of teeth (they become “sharpened”).
⚠️ Attention: If traces of oil are found on the timing belt, simply replacing the belt is not enough. It is necessary to find and eliminate the source of the leak (crankshaft oil seal, cover gasket or oil pump), otherwise the new belt will last no more than 10–15 thousand km.
Chain vs timing belt: which is more reliable on Nissan Cube
Owners Nissan Cube They often argue which timing drive is better: chain drive (CG13DE) or belt (HR15DE/KR15DE). Let's look at the pros and cons of each option:
| Criterion | Timing belt | Timing chain |
|---|---|---|
| Resource | 80–100 thousand km | 150–200 thousand km (with working tensioners) |
| Replacement cost | Low (repair kit ~5–7 thousand rubles) | High (chain + tensioners ~15–20 thousand rubles) |
| Noisiness | Silent | May rattle when cold when worn |
| Consequences of a cliff | Bent valves (intervention engine) | The risk is minimal (but damage to the dampers is possible) |
| Service | Regulatory replacement | Tension control every 60 thousand km |
Conclusion: the timing belt is cheaper to maintain, but requires strict adherence to regulations. The chain is more reliable, but its wear is more difficult to diagnose, and replacement is more expensive. If you buy Cube with mileage, be sure to check:
- On belt motors - the date of the last belt replacement (there must be an entry in the service book).
- On chain motors - the presence of extraneous noise during a cold start and the condition of the tensioner.
On HR15DE/KR15DE engines, the timing belt is a “zero-tolerance consumable”. Even if it looks normal outwardly, after 100 thousand km or 5 years of operation it must be replaced, regardless of its condition.
Frequently asked questions about timing marks on Nissan Cube
Is it possible to set timing marks without special clamps?
Yes, but it requires caution. Instead of using the factory retainers, you can use metal plates or even screwdrivers to lock the camshafts in the correct position. The main thing is to prevent them from turning when the belt is tensioned.
What should I do if the marks on the camshafts do not match after installing the belt?
Loosen the tension roller, remove the belt and manually tighten the camshafts until the marks align. Then reinstall the belt, starting at the crankshaft. Turn the engine by hand 2 turns and check the coincidence again.
How can you tell if the timing belt is broken?
If the belt breaks, the engine immediately stalls and it is impossible to start it. When you try to start, a metallic knock will be heard - this is the pistons hitting the valves. In this case, it is necessary to disassemble the engine and replace the valves (and often the pistons).
Do I need to change the rollers and pump when replacing the timing belt?
Yes, the rollers (tensioner and bypass) must be replaced - their service life is comparable to that of a belt. It is recommended to change the pump at every second belt replacement interval (every 180–200 thousand km), but if it starts to leak or play, it is replaced immediately.
Is it possible to drive with a worn timing belt if there are no signs of failure?
No. The belt may look intact, but its cord base is already weakened. The risk of breakage increases under high loads (for example, during towing or sudden acceleration). Replacement according to regulations is the only way to avoid serious damage.
