Timing belt in Nissan Almera Classic (models B10 And N16) is a critical element, the health of which determines the operation of the engine. An error when setting marks or ignoring belt wear can lead to valve bending, engine overhaul and expensive restoration. In this article we will look at where the timing marks are located on Almera Classic, how to set them correctly, and also consider the signs of belt wear and the nuances of replacement.
Engine Features GA14DE (1.4 l) and GA16DE (1.6 l), installed on Almera Classic, is interference design, where pistons and valves occupy the same space. If the belt breaks or the marks fail, they collide, which is guaranteed to lead to breakdown. Therefore, checking and replacing the timing belt must be carried out strictly according to the regulations - every 60–80 thousand km (or once every 4–5 years, even if the mileage is small).
What engines does the Nissan Almera Classic have and their features?
On Nissan Almera Classic series gasoline engines were installed GA with timing belt drive:
- 🔧 GA14DE (1.4 l, 87 hp) - the base engine for the markets of Europe and Asia. Has
16 valvesAnd single camshaft (SOHC). - 🔧 GA16DE (1.6 l, 100–109 hp) - a more powerful version with a similar design, but increased piston stroke.
Both engines are equipped hydraulic compensators, which simplifies the adjustment of valve clearances, but complicates the diagnosis of timing faults. For example, knocking sound under valve cover may indicate both wear on the rollers and problems with the hydraulic compensators. Main feature - no marks on the flywheel (unlike many other cars), which requires care when installing the belt.
On Almera Classic with engine GA16DE (after 2003) sometimes found double camshaft (DOHC), but in most cases it is SOHC-version. You can determine the engine type by the VIN code or markings on the cylinder block.

Where are the timing marks on the Nissan Almera Classic?
Timing marks on Nissan Almera Classic located on three key elements:
- Crankshaft pulley — a mark in the form of a dot or marks on the ring gear, combined with the ebb on the cylinder block.
- Camshaft pulley — the mark on the gear must coincide with the protrusion on the rear timing cover.
- Oil pump (for some versions) - an additional mark on the pump gear, but it is auxiliary and is not always used.
Feature Almera Classic — no mark on the flywheel, which complicates verification. Instead, they focus on crankshaft mark And camshaft. To access tags you need:
- 🔧 Remove right engine mount (for convenience).
- 🔧 Dismantle valve cover (to see the camshaft mark).
- 🔧 Remove timing belt guard (top and bottom parts).
On GA16DE (DOHC) The camshaft marks must coincide with each other and with the crankshaft mark. On SOHC-version, it is enough to align the camshaft mark with the protrusion on the cover and the crankshaft mark with the ebb on the block.
How to check the marks without removing the casing?
On some copies, the crankshaft mark can be seen through the technological hole in the lower part of the casing (next to the generator pulley). To do this you will need a flashlight and a mirror. However, this method does not guarantee 100% accuracy - it is better to remove the casing.
Signs of a faulty timing belt and rollers
Worn timing belt or rollers on Nissan Almera Classic manifests itself with the following symptoms:
- ⚠️ ticking sound from the timing drive side (especially on a cold engine). Most often indicates wear and tear tension roller or pump bearing.
- ⚠️ Vibration at idle, which disappears as the speed increases. Can talk about belt slippage due to weak tension.
- ⚠️ Power dips and unstable engine operation is a sign knocked down marks or a stretched belt.
- ⚠️ Oil leak from under the timing cover - often accompanies wear of the camshaft seals, which accelerates the destruction of the belt.
Critical malfunction: if the timing belt on the Almera Classic breaks, the engine will stall and will not start. An attempt to start will lead to the pistons hitting the valves and deforming the latter. In this case, it will be necessary to replace the valves, and sometimes the piston group.
To diagnose the condition of the belt without disassembling, you can use bench test:
- Stop the engine and open the hood.
- Remove the oil filler cap and try to turn the crankshaft by hand (using the pulley bolt).
- If you feel jamming or backlash, this is a sign of wear on the rollers or belt.
On Almera Classic with a mileage of more than 100 thousand km, it is recommended to change not only the timing belt, but also pump, even if it doesn't flow. Its lifespan often coincides with the lifespan of the belt, and replacement after a break will cost more.
Step-by-step instructions for replacing the timing belt
Replacing the timing belt with Nissan Almera Classic Requires accuracy and precise adherence to marks. Below is the instruction for the engine GA16DE (SOHC) - the most common option.
Required tools:
- 🔧 Set of sockets and keys (10, 12, 14, 17 mm).
- 🔧 Special key for the tension roller (or puller).
- 🔧 Jack and engine support.
- 🔧 Valve cover sealant.
Work order:
- Preparation:
- Disable
negative battery terminal. - Remove right engine mount and jack up the engine.
- Dismantle generator and its bracket for access to the crankshaft pulley.
- Disable
- Removing the old belt:
- Install the piston of the 1st cylinder in TDC (align the marks).
- Loosen the tension roller and remove the belt.
- Installing a new belt:
- Place the belt over the pulleys, starting at the crankshaft.
- Tension the belt with a roller (tightening torque -
20–25 Nm). - Rotate the crankshaft 2 turns and check that the marks match.
☑️ Check before starting the engine
Important! On GA16DE (DOHC) The order of installation of the belt is different - first it is put on the intake camshaft pulley, then the exhaust camshaft, and only then on the crankshaft. Also required to use camshaft clampsto avoid turning them.
Diagrams and photos of timing marks
Below are diagrams of the location of marks for engines GA14DE And GA16DE (SOHC):
| Engine | Crankshaft mark | Camshaft mark | Additional labels |
|---|---|---|---|
| GA14DE | The point on the pulley is aligned with the ebb on the block | Mark on the camshaft gear - with a protrusion on the cover | No |
| GA16DE (SOHC) | Same as GA14DE | Mark on the gear + additional protrusion on the back cover | Oil pump gear mark (optional) |
| GA16DE (DOHC) | Point on crankshaft pulley | The marks on both camshafts (intake/exhaust) coincide with the protrusions | Camshaft clamps are required |
Photo of marks (symbol):
On DOHC-camshaft mark versions must be symmetrical relative to the axis of the block head. If one of the marks is knocked down, this will lead to a violation of the valve timing and unstable engine operation.
On an Almera Classic with a GA16DE (DOHC) engine, you cannot turn the crankshaft with the belt removed - this will lead to the pistons hitting the valves!
Common mistakes when replacing a timing belt
Even experienced craftsmen sometimes make mistakes that lead to serious damage. Here are the most common:
- ❌ Incorrect belt tension:
Weak tension leads to slippage and tag failure, and excessive accelerated wear belt and rollers. The optimal tension is checked by deflecting the belt between the pulleys (there should be
5–7 mmwhen pressed with a finger). - ❌ Ignoring the oil pump mark:
On some GA16DE There is an additional mark on the pump gear. If it is not combined, it can lead to insufficient lubrication and engine jamming.
- ❌ Reusing an Old Tensioner Pulley:
The roller wears out along with the belt, and it definitely needs to be changed every time the timing belt is replaced. Savings of 500–800 rubles can result in a major overhaul.
⚠️ Attention! On Nissan Almera Classic with air conditioning, the timing belt must be removed when replacing compressor pulley. If this is not done, the belt may catch on it and break during the first start.
Another common mistake is failure to check engine operation after replacement. After assembly you need:
- Rotate the crankshaft by hand 2 turns and make sure that the marks match.
- Start the engine and listen to it idle (there should be no extraneous noise).
- Check oil pressure (on the dashboard) - if it does not rise, the oil pump gear may be installed incorrectly.
Cost of replacing a timing belt and where is the best place to do it
Timing belt replacement price Nissan Almera Classic depends on the region and type of service:
| Service | Cost (RUB) | Notes |

- 🔧 Specialized service for Nissan — the best option (price/quality).
- 🔧 On your own - only if you have experience and tools (savings up to 50%).
When choosing spare parts, give preference to the following brands:
- 🏆 Gates - best price/quality ratio.
- 🏆 Contitech - original supplier for many cars.
- 🏆 Dayco - a budget option, but the quality is lower.
⚠️ Attention! There are many fake Gates brand timing kits on the market. The original packaging has hologram and serial number, which can be checked on the manufacturer's website.
FAQ: Frequently asked questions about timing marks on Nissan Almera Classic
Is it possible to drive if the timing belt begins to “eat up” on one edge?
No! One-sided belt wear indicates pulley misalignment or roller bearing wear. Further operation will lead to belt breakage and valve bending. It is necessary to urgently diagnose the cause (most often it is tension roller or pump).
How to check timing marks without removing the cover?
On Almera Classic this is almost impossible due to the design of the casing. The maximum that can be done is to check the crankshaft mark through the technological hole (if there is one). For accurate diagnosis be sure to remove the cover.
What happens if the marks are not aligned when replacing the belt?
If the marks are off 1–2 teeth, the engine will operate unstably (trouble, jerk). When there is a discrepancy by 3 teeth or more will happen collision of pistons with valves, which will lead to bending of the latter and the need to repair the block head.
Do I need to change the pump when replacing the timing belt?
On Almera Classic The pump is driven by a timing belt, so its lifespan coincides with the lifespan of the belt. If the car's mileage exceeds 100 thousand km, pump definitely needs to be replaced, even if it doesn't flow. Otherwise, the risk of belt breakage due to a jammed pump increases significantly.
What timing belt tension is considered normal?
Normal tension is checked as follows:
- Pull the belt between the crankshaft and camshaft pulleys.
- Turn it with your finger - the deflection should be 5–7 mm.
- If the deflection is greater, the belt is loose; if it is less, it is overtightened.
For fine adjustments, use torque wrench (roller tightening torque - 20–25 Nm).
