Nissan March K11 - a compact and reliable hatchback that has gained popularity due to its efficiency and ease of maintenance. However, even such an unpretentious machine has weaknesses, one of which is gas distribution mechanism (GRM). Incorrectly setting the marks when replacing a belt or chain can lead to serious damage: from loss of power to valves meeting pistons.
In this article you will find detailed instructions for setting timing marks for engines CG10DE (1.0 l), CG13DE (1.3 l) and GA14DE (1.4 l), which were installed on March K11. We will figure out where the marks are, how to align them correctly, what tools are needed and what Even experienced mechanics often make mistakes.. You will also learn the consequences of ignoring this procedure and how to check the operation of the mechanism after assembly.
Why is it important to correctly set the timing marks on the Nissan March K11
The gas distribution mechanism is responsible for synchronizing the operation of the crankshaft and camshaft. If the marks are knocked down, the valve timing is disrupted, which leads to:
- 🔥 Engine knock — the fuel mixture ignites spontaneously, which destroys the pistons and cylinders.
- 🚗 Loss of power — the car accelerates poorly, “stumbles” when picking up speed.
- 💥 Impact of valves on pistons - the most serious consequence requiring major repairs.
- ⚡ Unstable operation at idle — the engine stalls, stalls or runs jerkily.
On Nissan March K11 with engines CG series (1.0/1.3) and GA14DE (1.4) It is easier to set the timing marks than on more modern engines with a phase change system. However, even here there are nuances: for example, on GA14DE the mark on the flywheel is often hidden under the boot, and on CG10DE you need to take into account the position of the distributor.
⚠️ Attention: If after replacing the timing belt the engine does not start or runs intermittently, don't try to start it again - this can worsen the damage. Check the alignment of the marks first!
What tools will you need for the job?
To independently set timing marks on Nissan March K11, prepare:
- 🔧 Set of sockets and keys (10, 12, 14 mm are the most popular sizes).
- 🔩 Socket wrench for crankshaft (usually 19 or 22 mm).
- 📏 Caliper or ruler — to check the position of the marks.
- 🔦 Flashlight or lamp — marks on the flywheel are often difficult to see.
- 🖌️ Marker or proofreader - to mark the position of the marks before disassembling.
- 🛠️ Puller for crankshaft pulley (if you plan to remove it).
May also be useful torque wrench to tighten the bolts to the correct torque (especially important for the crankshaft pulley). If you have an engine GA14DE, prepare additionally special camshaft retainer (can be made from a metal plate).

Where are the timing marks on the Nissan March K11
The location of the marks depends on the engine type. Below is a table with a description for each modification:
| Engine | Mark on camshaft | Mark on the crankshaft | Additional labels |
|---|---|---|---|
| CG10DE (1.0 l) | The protrusion on the camshaft gear should coincide with the mark on the rear timing cover. | The mark on the crankshaft pulley is aligned with the mark on the front cover (0° TDC). | Mark on the flywheel (visible through the inspection window on the gearbox). |
| CG13DE (1.3 l) | Likewise CG10DE, but the mark on the cover is shifted 2 mm to the left. | Same as on CG10DE. | The mark on the distributor (should point to the first cylinder). |
| GA14DE (1.4 l) | The two marks on the camshaft gears (intake/exhaust) are aligned with the protrusions on the rear cover. | Mark on the crankshaft pulley + mark on the flywheel (visible through the hatch on the gearbox). | The camshaft lock is required during assembly! |
On all engines March K11 label TDC (top dead center) the first cylinder is indicated by a mark on the crankshaft pulley. However, in practice, many mechanics rely on the flywheel mark, since it more accurately shows the position of the piston.
How to find the mark on the flywheel?
On engines CG10DE/CG13DE the mark is hidden under a rubber plug on the gearbox (flywheel side). Remove the plug with a screwdriver - you will see a mark inside, which should coincide with the triangular cutout on the gearbox housing. On GA14DE the mark is visible through the plastic hatch (you will have to remove the air duct).
Step-by-step instructions: how to set timing marks
The tagging process is the same for most engines. Nissan March K11, but there are nuances for each motor. Let's consider a universal algorithm:
- Remove the upper timing cover (unscrew 4-6 bolts). On GA14DE Additionally, remove the plastic casing.
- Crank the crankshaft clockwise (by the pulley bolt) until the mark on the pulley aligns with the mark on the front cover.
- Check the mark on the flywheel — it should coincide with the cutout on the gearbox. If not, rotate the crankshaft another 360°.
- Lock the camshafts (on GA14DE be sure to use a retainer!). The marks on the gears should match the ridges on the back cover.
- Put on the timing beltstarting at the crankshaft, then tension it through the tension roller (on CG series the roller is automatically tensioned by a spring).
- Turn the crankshaft 2 turns and check the alignment of the marks. If everything matches, assemble the mechanism.
On engines CG10DE/CG13DE after installing the belt it is necessary adjust valve clearance (norm: 0.20–0.25 mm on inlet and 0.30–0.35 mm on exhaust). On GA14DE The gaps are regulated by hydraulic compensators, but after replacing the belt they are worth checking.

⚠️ Attention: On GA14DE Do not turn the crankshaft counterclockwise after removing the belt - this may shift the valve timing. Always turn in the direction of rotation!
Common mistakes and how to avoid them
Even experienced mechanics sometimes make mistakes when installing timing marks on Nissan March K11. Here are the most common of them:
- 🔄 The crankshaft was turned not 2 turns, but 1. — the marks will coincide, but the phases will be out of alignment by 180°. The engine will not start.
- 🔧 Camshafts not fixed on GA14DE — after tightening the gears, they can turn, which will lead to valve impact.
- 📏 Ignored the mark on the flywheel — we were guided only by the crankshaft pulley, which gives an error of ±5°.
- 🛠️ The tension roller was not replaced — the old roller may jam, which will lead to belt slipping.
- 🔩 Tightened the crankshaft pulley bolt - this deforms the thread and can lead to bolt breakage.
To avoid problems, always check the labels at least twice and use a torque wrench to tighten the bolts. On GA14DE After assembly, be sure to check the compression in the cylinders - if it is below 10 bar, it means the valves are bent.
If after replacing the timing belt the engine does not start, but the starter turns, try removing the distributor cover (on CG series) and turn its slider 180°. This often helps if the marks were set incorrectly.
What to do if the tags are knocked down: symptoms and solutions
If the timing marks are on Nissan March K11 knocked down, the engine will behave abnormally. Here are the main signs and diagnostic methods:
| Symptom | Probable Cause | Solution |
|---|---|---|
| The engine does not start, but the starter turns | The marks are off by 180° (phases are shifted) | Rotate the crankshaft 360° and re-align the marks |
| The engine is shaking, popping noises are heard in the exhaust system | Mark mismatch by 5–10° | Set the marks accurately, check the compression |
| Engine knocking during operation | The valves touch the pistons (critical mark displacement) | Urgently remove the cylinder head, check the valves and pistons |
| Loss of power, jerking during acceleration | The marks are knocked down by 2–3 teeth of the belt | Reinstall the timing belt with precise marks |
If you suspect that the marks are knocked down, don't start the engine — it’s better to immediately remove the timing cover and check the position of the shafts. On CG series You can try to correct the marks by turning the crankshaft manually. On GA14DE at the slightest suspicion of valve shock, engine disassembly is required.

FAQ: Frequently asked questions about timing marks on the Nissan March K11
Is it possible to set timing marks without special tools?
On engines CG10DE/CG13DE you can do without clamps, but GA14DE Without them, the risk of camshaft misalignment is very high. As a last resort, you can make a retainer from a metal plate using a template.
How often should timing marks be checked?
The marks are checked every time the timing belt is replaced (every 60–80 thousand km). It is also worth checking them if the engine starts to run unstable or after an impact in the front of the car (the crankshaft pulley may move).
What happens if the timing belt jumps 1 tooth?
On CG series This will lead to loss of power and unstable operation. On GA14DE can bend the valves, since the gap between them and the pistons is minimal. In both cases, you need to urgently reinstall the belt.
Do I need to change the rollers when replacing the timing belt?
Yes, necessarily. The tension and idler rollers wear out along with the belt. If you leave the old ones, they can jam, which will lead to a broken belt and serious engine damage.
Is it possible to start the engine with the timing belt removed?
No! Without a belt, the camshafts will not rotate and the valves will remain in the open position. When cranking the crankshaft, the pistons will hit the valves, which will lead to their deformation.
