When to change the timing belt on a Nissan Almera G15: regulations and signs of wear
Manufacturer Nissan recommends replacing the timing belt every 100–120 thousand km or once every 5–6 years (whichever comes first). However, these figures are relevant for ideal operating conditions: moderate climate, no overloads and high-quality consumables. In reality, the belt may become unusable much earlier.
Factors that reduce the service life of the timing belt by Almera G15:
- 🔥 Extreme temperatures: Frequent driving in traffic jams in summer or frost in winter accelerates the aging of rubber.
- 💦 Oil or antifreeze ingress: even a small leak of oil seals or pumps destroys the structure of the belt.
- 🚗 Aggressive driving style: sudden starts and braking increase the load on the drive.
- ⚙️ Poor quality rollers or tensioner: Bearing wear leads to belt misalignment.
Signs that the timing belt requires urgent replacement:
- 🔊 Whistling or squeaking from the drive side when starting the engine.
- 🔄 Uneven motor operation at idle (may indicate slippage).
- 🛑 Cracks, delamination or scoring on the surface of the belt (visible upon visual inspection).
- 💥 Extraneous knocks in the timing area - breakage or critical wear of the rollers is possible.
⚠️ Attention: On Nissan Almera G15 with engine HR16DE broken timing belt in 90% of cases it leads to bending of the valves. This means that in addition to replacing the belt, the cylinder head will need to be repaired (cost: from 50 thousand rubles). Don't take risks!
What spare parts and tools are needed to replace the timing belt?
Before starting work, prepare everything you need. It’s not worth saving on spare parts: a low-quality belt or rollers can break after 20–30 thousand km. Optimal kits for Almera G15:

Tools you will need:
- 🔧 Set of sockets and keys (10, 12, 14, 17 mm).
- 🔩 Torque wrench (for tightening bolts to the required torque).
- 🔗 A special key for the timing belt tensioner (or a homemade one made from two nails).
- 🔍 Flashlight or lamp for illuminating hard-to-reach places.
- 📏 Vernier calipers (to check the protrusion of the piston of the 1st cylinder).
- Every 20 thousand km
- Just before replacement
- Never checked
- I don't know how to do this
If you plan to replace your pump, additionally prepare:
- 🧰 Sealant for gasket (
Loctite 574or equivalent). - 💧 Antifreeze (about 5 liters for
HR16DE). - 🧽 Rags and container for draining coolant.
⚠️ Attention: When purchasing a timing belt, check its authenticity! Fake belts Gates or Contitech often sold with incorrect markings and can break after 10–15 thousand km. The original belt must have a holographic sticker and a clear identification number.
Preparing the car: draining antifreeze and dismantling components
Before replacing the timing belt, it is necessary to ensure access to the mechanism. On Nissan Almera G15 To do this you will need to remove:
- Right headlight (disconnect the power connector!).
- The battery and the platform under it.
- Air filter with pipes.
- Generator (disconnect the terminals and unscrew the fasteners).
- Timing cover (upper and lower).
If you plan to replace the pump, drain the antifreeze first:
- Place the car on a level surface.
- Remove the engine protection (if equipped).
- Place a container under the drain hole on the radiator.
- Unscrew the plug on the radiator and cylinder block (14 mm wrench).
- Wait until the liquid is completely drained (about 10–15 minutes).

Important point: before removing the timing belt be sure to tag! This will save you from assembly errors. On Almera G15 the marks are located:
- On the crankshaft pulley (must match the mark on the block).
- On the camshaft sprocket (aligned with the mark on the cover).
- On the flywheel (visible through the inspection window in the clutch housing).
If the marks do not match, rotate the crankshaft with a 19 mm wrench (clockwise) until they align. Do not use a starter for this!
Step-by-step instructions for replacing the timing belt on a Nissan Almera G15
Now let's move on to the main stage. Follow the instructions strictly in order to avoid mistakes.
Step 1. Fixing the crankshaft and camshafts
After aligning the marks, secure the crankshaft and camshafts with special clamps (or homemade devices). This will prevent them from turning when removing the belt. On HR16DE to fix the camshafts, you can use a 5 mm thick plate inserted between the teeth of the sprockets.
Step 2. Removing the old belt
- Loosen the tensioner bolt (14 mm wrench) and move the roller to the side.
- Remove the belt from the camshaft sprockets and crankshaft.
- Check the condition of the rollers: they should rotate without play or noise.
Step 3: Install a new belt
Place the new belt on the crankshaft sprocket, then on the pump (if you are not replacing it), the idler pulley and the camshafts. Make sure belt movement direction matches the arrows on it (usually indicated on the outside).
Step 4: Belt Tension
Use a special tensioner wrench (or two nails inserted into the holes). Turn the tensioner counterclockwise until the marks on the body align, then tighten the bolt to torque 20–25 Nm.
Step 5: Check marks and test run
Turn the crankshaft 2 turns clockwise and check that the marks match. If everything is correct, reassemble the components in the reverse order, fill in antifreeze and start the engine. For the first 5–10 minutes, monitor the operation of the motor: there should be no extraneous noise or vibration.
If after replacing the timing belt the engine shakes or runs unevenly, check the valve timing. The tags may have been set incorrectly. In this case, repeat the belt tensioning procedure.
Typical mistakes when replacing timing belts and how to avoid them
Even experienced professionals sometimes make mistakes that lead to serious consequences. Here are the most common of them:
1. Incorrect placement of labels
If the marks on the crankshaft and camshafts do not match, the engine will run erratically or may not start at all. Always check them twice before launch!
2. Belt over-tightening or under-tightening
Too much tension accelerates wear on the belt and bearings, while too little tension causes slippage. Use a torque wrench and follow the manufacturer's recommendations (20–25 Nm for tensioner).
3. Ignoring replacement of rollers
Many people save by leaving old videos. This is a big mistake: worn bearings can jam, which will lead to belt breakage. The rollers always change along with the belt!
4. Dirt or oil on the belt
Before installing a new belt, thoroughly clean all surfaces. Even a small amount of oil or dust will shorten its service life by 2-3 times.
5. Use of low-quality spare parts
Do not buy timing belts from unknown brands! Optimal options for Almera G15 — Gates, Contitech or original Nissan.
What to do if the engine does not start after replacing the timing belt?
If the starter turns, but the engine does not start, check:
1. Timing timing marks coincide (perhaps the belt has slipped off).
2. Connection of the crankshaft position sensor (may be damaged during dismantling).
3. Presence of spark and fuel supply.
If the marks are knocked down, re-disassemble the mechanism and align them according to the instructions.
Cost of timing belt replacement: comparison of self-repair and car service
Timing belt replacement price Nissan Almera G15 varies depending on region and service level. Let's look at the average prices:
| Service/Spare part | On your own (RUB) | Car service (RUB) |
