Replacing the timing belt on Nissan Almera G15 1.6 (K4M): instructions from A to Z

Replacing the timing belt (timing belt) on Nissan Almera G15 with engine K4M (1.6 l) is a critical procedure that many owners put off until the last minute. Meanwhile, a broken belt on this engine almost always leads to valve bending and major repairs. The official regulations require changing the belt every 60–90 thousand km, but the actual period depends on operating conditions: in the Russian climate with its temperature changes and poor-quality roads, it is better to reduce the interval to 50–60 thousand km.

In this article you will find step-by-step instructions with photos, a list of necessary tools, consumables and unique timing marks for the K4M engine, which are often confused with analogues from Renault. We will also analyze common mistakes (for example, why you cannot turn the crankshaft counterclockwise) and give advice on choosing spare parts - from budget Gates up to bonus Contitech. If you have never done such work, the article will help you assess the complexity of the task and decide whether it is worth taking on it yourself or whether it is better to trust the service.

When to change the timing belt on Almere G15: signs of wear and regulations

Manufacturer Nissan indicates in the manual the interval for replacing the timing belt in 90,000 km, but this period is relevant for ideal conditions: moderate climate, high-quality fuel and original spare parts. In the realities of Russian operation, the belt wears out faster due to:

• 🌡️ Temperature changes — rubber material loses elasticity in frosts below –20°C and cracks in heat above +30°C.
• 🛣️ Bad roads — vibrations and shocks accelerate belt stretching and roller wear.
• ⛽ Low quality oil — if the oil “leaves” into the engine, its vapors corrode the rubber of the belt.
• 🔧 Non-original spare parts - cheap belts (for example, Trialli or Fenox) can stretch out after 30–40 thousand km.

In addition to mileage, the need for replacement is indicated indirect signs:

• 🔊 Whistling or rustling noise on the drive belt side (may indicate wear on the tensioner pulley).
• 🚗 Jerks when moving at low speeds - a signal about belt slipping.
• ⚠️ Check Engine with errors P0340 (camshaft position sensor) or P0335 (crankshaft sensor).
• 🔧 Cracks or delaminations on the belt (visible upon visual inspection).

⚠️ Attention: If there are signs on the timing belt transverse cracks (even small ones) or cord threads are sticking out - replacement must be carried out immediately. On the engine K4M A broken belt is guaranteed to lead to valves meeting pistons and repairs costing 100+ thousand rubles.

To accurately determine the condition of the belt, remove the upper timing cover (three 10mm bolts) and inspect it in good light. Normal belt should be free of cracks, with a clear tooth pattern and without traces of oil. If you notice at least one of the defects, get ready for replacement.

What spare parts and tools will you need?

To replace the timing belt with Almera G15 will be required set of spare parts And special tool. Don’t skimp on consumables—cheap analogues often cause breakdowns. Below is a table with verified articles and estimated prices (for 2026):

Name	Article (original/analogue)	Price, ₽	Notes
Timing belt	Nissan 130C1-4M505 / Gates 5631XS / Contitech CT1179	2 500–4 000	The original comes complete with rollers
Tensioner roller	Nissan 13070-4M500 / SKF VKM 35600	1 800–2 500	It is better to take one with a metal case
Bypass roller (parasitic)	Nissan 13090-4M500 / INA 531 0331 10	1 200–1 800	Often comes with a belt
Pump (water pump)	Nissan 21010-4M505 / Hepu P967	3 500–5 000	It is recommended to change it together with the timing belt
Pulley bolts	Nissan 11026-01M02 (set)	300–500	Disposable, always new!

For tools you will need:

• 🔧 Head set (10, 13, 16, 18 mm) and extension.
• 🔨 19 mm socket wrench for the crankshaft pulley (you need a powerful wrench).
• 🔩 Torque wrench (for tightening bolts with a torque of 20–50 Nm).
• 📏 Vernier caliper or a ruler to check belt tension.
• 🔗 Special key for tensioner (can be replaced with two nails and pliers).
• 🔦 Flashlight and a mirror for inspecting marks.

⚠️ Attention: If you buy timing kit, check that it contains all three videos (tension, bypass and parasitic). Some sellers give out incomplete sets, passing them off as complete ones. For example, in the set Gates K015631XS There is no deflection roller - you will have to purchase it separately.

Also prepare consumables:

• 🧴 Sealant (For example, Loctite 574) for the pump cover.
• 🧼 Carburetor Cleaner to remove dirt from marks.
• 🛢️ Antifreeze (1–2 liters) for topping up after replacing the pump.
• 🧤 Gloves and rags - dirty work!

Preparing the car: draining the antifreeze and removing the drive belts

Before replacing the timing belt, you must prepare the car and provide access to the mechanism. Perform work on flat ground with the handbrake on. Here is a step-by-step algorithm:

1. Remove the negative battery terminal (10 mm wrench).
2. Drain the antifreeze:
   • Place a container under the drain hole on the radiator (bottom right).
   • Unscrew the plug (plastic) counterclockwise.
   • Unscrew the plug on the cylinder block (13 mm head) to drain completely.
3. Remove the alternator and air conditioner drive belt:
   • Loosen the tension roller (13 mm wrench).
   • Slide the belt and remove it from the pulleys.

Remove the right front wheel and plastic mudguard (4 pistons and 2 10 mm bolts).

Remove the upper timing cover (3 bolts per 10 mm).

Now you need fix the crankshaftso that it does not turn when the pulley is unscrewed. To do this:

1. Turn on 5th gear and have a helper apply the brake.
2. Or insert a screwdriver into the flywheel teeth through the hole in the clutch housing (to the right of the cylinder block).
3. Unscrew the crankshaft pulley bolt (19 mm socket + extension). Tightening torque during reassembly - 95–110 Nm.

After removing the crankshaft pulley you will see lower timing cover (fastened with 3 10 mm bolts). Remove it and clean the surface of dirt - this will make it easier to install the marks. If the lid is stuck, do not break it: water WD-40 around the perimeter and wait 10 minutes.

Installing timing marks on the K4M engine: step-by-step instructions with photos

The most important stage is mark alignment. On the engine K4M there are three of them:

1. Mark on the crankshaft (toothed pulley).
2. Mark on the intake camshaft.
3. Mark on the exhaust camshaft.

If even one mark is knocked off, the engine will not start or will run intermittently. Here's how to set them:

1. Crank the crankshaft clockwise (by the pulley bolt) until the mark on the toothed pulley aligns with protrusion on the cylinder block (see photo below). The label must look straight up (for 12 hours).
   Photo of the crankshaft mark

   There is a small protrusion on the crankshaft pulley (a tooth without a chamfer), which should coincide with the casting on the block. If the mark is not visible, clean the pulley from dirt.

2. Check the camshaft marks:
   • On intake shaft (right) label is notch on the pulley, which should coincide with tendril on the timing cover.
   • On exhaust shaft (left) label - point on the pulley, combined with the ebb on the lid.

If the marks do not match, carefully rotate the camshafts clockwise only (use a 16mm wrench).

Lock the camshafts a special retainer (for example, Mot. 1489) or a homemade device made from a metal plate. This will prevent them from turning when the belt is removed.

Important! On the engine K4M no mark on flywheel (unlike Renault Logan), so you can only navigate by the crankshaft pulley. If you are in doubt about the correct installation, take a photo of the position of the marks before disassembling.

After checking the labels, you can proceed to removing the old belt:

1. Loosen the tension pulley bolt (13 mm wrench) and remove the belt.
2. Check the condition of the rollers: they should rotate silently, without play.
3. If you plan to change the pump, drain the remaining antifreeze and unscrew it (3 bolts of 10 mm).

Installing a new timing belt and tensioning

Before installing a new belt clean all pulleys and rollers from dirt and oil (use WD-40 or carburetor cleaner). Also check condition of the seals crankshaft and camshafts - if they are leaking, replace them, otherwise the oil will quickly ruin the new belt.

Installation algorithm:

1. Place the belt on the crankshaft pulley, then to the pump (if it is new), idler roller and camshafts. Last there must be a tension roller.
2. Pull the belt:
   • Rotate the tension roller counterclockwise (use a special wrench or nails in the holes).
   • Tighten the roller bolt to torque 20–25 Nm.
   • Check the tension: the belt should rotate 90° when applying a force of 2 kg between the camshaft pulleys.

Turn the crankshaft 2 turns clockwise and check the marks again. If they match, the build was successful.

To check the tension you can use laser thermometer (heat the belt to 60–70°C and check the deflection) or a special strain gauge. If there is no such tool, focus on visual inspection:

• ✅ Norm — the belt does not sag, but is not too tight (you can turn it 90° by hand).
• ❌ Weak tension — the belt sags by more than 1 cm, a whistle is heard during operation.
• ❌ Strong tension — the belt does not turn by hand, the rollers hum.

⚠️ Attention: If you tighten the belt, it will wear out 2–3 times faster, and the roller bearings will fail after 10–15 thousand km. Weak tension is no less dangerous: the belt can skip 1–2 teeth, which will lead to a failure of the valve timing and an error P0340.

After tensioning the belt install the lower and upper timing covers, tightening the bolts to torque 10 Nm. Don't forget about new crankshaft pulley bolts - old ones cannot be used!

Assembly and first launch: what to check after replacement

After installing the timing belt, reassemble everything in the reverse order:

1. Install the crankshaft pulley and tighten the bolt to torque 95–110 Nm.
2. Put on the generator and air conditioner drive belts and adjust the tension.
3. Refill with new antifreeze (recommended Nissan Coolant L255N or equivalent CoolStream A-110).
4. Connect the battery terminal.

Before the first launch be sure to check:

• 🔧 Tightening all bolts (especially the crankshaft pulley and tension roller).
• 🚗 No foreign objects in the engine compartment.
• 💧 Antifreeze level (must be between MIN and MAX).
• 🔌 Connecting all sensors (especially DPRV and DPKV).

Start the engine and listen:

• ✅ Norm — smooth sound, no vibrations, stable speed (800–900 rpm).
• ❌ Problems:
  • 🔊 Whistling — low tension of the generator or timing belt.
  • 🛑 The engine stalls — timing marks are knocked off.
  • ⚠️ Check Engine light on — valve timing error (P0340 or P0335).

If the engine is running rough, turn it off immediately and check the labels. Restarting with missing phases can lead to valve bending!

Typical mistakes when replacing the timing belt on an Almere G15 and how to avoid them

Even experienced craftsmen sometimes make mistakes when replacing a timing belt. Here TOP-5 most common mistakes and how to prevent them:

1. Broken camshaft marks

   Reason: Rotating camshafts when the belt is removed or incorrect fixation.

   How to avoid: Use a camshaft lock or mark their position with a marker before disassembling.

2. Belt that is too tight or too tight

   Reason: Tension “by eye” without checking the deflection.

   How to avoid: Use a torque wrench on the pulley and check the belt deflection.

3. Ignoring pump replacement

   Reason: The desire to save money, although the pump is already worn out.

   How to avoid: If the mileage is more than 100 thousand km, the pump necessarily change - its jamming leads to belt breakage.

4. Reusing old bolts

   Reason: Crankshaft pulley and tension roller bolts - disposable.

   How to avoid: Buy a new set of bolts (part number Nissan 11026-01M02).

5. Rotating the crankshaft counterclockwise

   Reason: Ignorance of engine features K4M.

   How to avoid: Crankshaft Can only be rotated clockwise - otherwise the belt may slip.

Another common mistake is use of non-original belts. For example, belts Trialli or Fenox often stretch after 20–30 thousand km, which leads to phase failure and error P0340. If your budget is limited, choose at least proven analogues:

• 🥇 Best choice: Gates 5631XS or Contitech CT1179.
• 🥈 Middle segment: Dayco 94080 or Bosch 1 987 949 584.
• 🥉 Budget option: Quarton QZT-1018 (temporary replacement only).

⚠️ Attention: If after replacing the timing belt the engine won't start or works intermittently, don't try to "arrive" - this will make the damage worse. Immediately check the marks and belt tension. Common mistake: mark on exhaust camshaft knocked down by 1 tooth, which leads to an error P0340 and engine tripping.

FAQ: Frequently asked questions about replacing the timing belt on a Nissan Almera G15

Is it possible to replace the timing belt on an Almere G15 without removing the pump?

Technically you can, but not recommended. On the engine K4M the pump is driven by the same timing belt, and its jamming is guaranteed to break the belt. If the car's mileage is more than 100 thousand km, the pump necessarily change along with the timing belt. The exception is if the pump is new (it was changed separately less than 50 thousand km ago).

What antifreeze should I fill in after replacing the timing belt?

For Nissan Almera G15 suitable antifreeze type D (carboxylate) with approval Nissan L255N. Optimal options:

• Nissan Coolant L255N (original, green).
• CoolStream A-110 (analog, red).
• Sintec Unlimited G12++ (universal, purple).

Cooling system volume - 6.7 liters, but with a partial replacement, 4–5 liters will be enough.

What happens if the timing belt breaks on an Almere G15?

On the engine K4M (1.6 l) 100% bends valves when the belt breaks. This occurs because the pistons "meet" the open valves. Repair costs 80–150 thousand rubles (replacing valves, guides, grinding in seats, sometimes replacing pistons). In rare cases it may be necessary cylinder head replacement.

The exception is engines with grooves in the pistons (found on some versions Renault), but on Almera G15 such pistons no.

Is it possible to drive with a whistling timing belt?

No! Timing belt whistling Almera G15 means one of the problems:

• 🔧 The tension is loose — the belt slips onto a tooth, which leads to a phase failure.
• 🛠️ Tensioner pulley wear - it can jam and break the belt.
• 💧 Oil ingress on the belt (the crankshaft or camshaft oil seal is leaking).

If the whistle appears when cold and disappears after warming up - the tension roller is to blame. If the whistle permanent — urgently check the tension and condition of the belt.

How much does it cost to replace the timing belt on an Almere G15?

The cost of replacing the timing belt in service depends on the region and level of the service station:

• 🔧 Official dealer: 12,000–18,000 ₽ (with spare parts).
• 🛠️ Unofficial service: 6,000–10,000 ₽ (without spare parts).
• 🏠 Self-replacement: 3,000–5,000 ₽ (spare parts only).
