Timing belt (timing belt) in Nissan Almera G15 (aka Nissan K15 for some markets) is a critical element, the failure of which leads to collision of pistons with valves and engine overhaul. Despite the official replacement regulations every 90–120 thousand km, the actual service life depends on operating conditions: city traffic jams, temperature changes and low-quality spare parts reduce it by 20–30%. This article contains a detailed analysis of the process of replacing the timing belt with your own hands, taking into account the pitfalls that are specific to Almera G15 with motors HR15DE And HR16DE.

If you have never worked with a timing belt, you should think three times before replacing it yourself. An error in installation even by one “tooth” will lead to a failure of the valve timing, and this means floating speed, loss of power, or the worst scenario: bending of the valves at the first start. But with the tools, patience and these instructions, the task is quite doable. We will analyze not only the replacement steps, but also how to check the coincidence of marks without special devices, what analogues of belts fit better than the original, and why on Almera G15 after 2016, additional tensioner adjustment may be required.

When to change the timing belt on a Nissan Almera G15: signs and timing

Official regulations Nissan for Almera G15 (including restyled versions) requires replacing the timing belt every 90,000 km or 6 years - whichever comes first. However, these figures are relevant for “ideal” conditions: moderate climate, high-quality oil and fuel, no overloads. In the realities of Russian roads and operation, the period is reduced to 70–80 thousand km, and in some cases - up to 60 thousand km.

Indirect signs that the belt requires replacement already now:

  • 🔊 Whistling or rustling noise from under the hood on a cold engine (may disappear after warming up).
  • 🔧 Cracks or fringe on the surface of the belt (visible upon visual inspection).
  • 📉 Power dips or unstable idle speed (may indicate belt slippage).
  • 🚨 Check Engine with errors in camshaft sensors (P0340, P0345).
⚠️ Attention: On Almera G15 with motor HR16DE (1.6 l) timing belt break guaranteed valve bending — this is a “plug-in” engine. On HR15DE (1.5 l) the risk is lower, but still present. Don't skimp on replacements!

Check the condition of the belt every 20–30 thousand km through the technological hatch in the protection (if there is one). On Almera G15 After 2015, the hatch is often missing - you will have to remove the right engine mount for inspection.

📊 How often do you check the condition of the timing belt?
  • Every 10 thousand km
  • Every 30 thousand km
  • Only when replacing
  • Never checked

What spare parts and tools are needed for replacement?

To replace the timing belt with Nissan Almera G15 you will need not only the belt itself, but also set of rollers (tension and bypass), as well as new bolts. Below is a table with article numbers of original parts and proven analogues:

Detail Original article Analogs (recommended) Note

Crankshaft pulley bolt 11026-4M50A Febi 27286, TRW JTS1001 Disposable! Tightening 100–120 Nm

Of the tools you will definitely need:

  • 🔧 Torque wrench (for the crankshaft pulley bolt and tension roller).
  • 🔨 Special key for tensioner (or homemade from two M6 bolts).
  • 🔩 Socket heads at 10, 12, 14, 17 and 19 mm (deep and standard).
  • 🔧 5 mm hexagon for fixing camshafts.
  • 🛠️ Circlip remover (to remove the pump pulley).
💡

Before purchasing a timing belt, check it for rotation direction arrow and marks for alignment. On fakes they are often missing, which leads to installation errors.

Preparing the car: draining the antifreeze and removing the protection

Replacing the timing belt with Nissan Almera G15 more convenient to carry out on lift or inspection hole, but in the absence of such, a jack with reliable stops will do. First of all disconnect the battery (remove the negative terminal) and drain the antifreeze - you will have to partially drain it to get to the lower protection.

Procedure:

  1. Set the car to the handbrake and place chocks under the rear wheels.
  2. Remove right headlight (unscrew the 3 10 mm bolts and disconnect the connector).
  3. Unscrew the fastening bolts bumper on the right (2 10 mm bolts and 2 pistons).
  4. Drain the antifreeze through lower radiator hose (loosen the clamp and place the container).
  5. Remove right engine mount (3 bolts of 14 mm and 1 bolt of 17 mm).
⚠️ Attention: On Almera G15 after 2017, the engine mount can be bolted with thread lock (red). When unscrewing, apply force strictly perpendicularly so as not to break the threads in the block!

After removing the support, the engine will rise - secure it jack through a wooden spacer under the pallet. Do not lean on the oil pan!

Removing the old timing belt: step-by-step instructions

Now we move on to the most important stage - removing the belt. Main rule: do not rotate the crankshaft or camshafts after removing the belt, otherwise the marks will be lost and you will have to set the phases again.

Algorithm of actions:

  1. Remove alternator drive belt (loosen the tensioner with a 14mm wrench).
  2. Unscrew the bolt crankshaft pulley (you will need an extension and a 19mm socket). To lock the crankshaft, engage 5th gear and apply the brake (or use a special stopper).
  3. Remove the crankshaft pulley and lower timing cover (4 bolts x 10 mm).
  4. Expose timing marks:
    • The mark on the camshaft (intake) pulley should coincide with the protrusion on the cover.
    • The mark on the crankshaft pulley should be opposite indicator on the oil pump.
  • Loosen the tension pulley bolt (14 mm wrench) and remove the belt.

    • On Almera G15 with motor HR16DE there is a nuance: second camshaft (exhaust) also has a mark, but it is less noticeable. Use a mirror or flashlight to check.

    What to do if the labels don't match?

    If the marks do not match when removing the belt, it means that it was installed incorrectly earlier or has slipped. In this case:

    1. Rotate the crankshaft until the mark on it aligns.

    2. Make sure that both camshafts are in the “closed-open” position (cams of the 1st cylinder point up and down).

    3. If the marks do not match, you will need a special tool for fixing the camshafts (or homemade devices made from bolts).

    Installing a new timing belt and tensioning

    Before installing a new belt thoroughly clean all pulleys and rollers remove dirt and oil (use a lint-free cloth and brake cleaner). Oil on the belt or pulleys reduces its life by 2-3 times!

    Installation procedure:

    1. Install new tension roller (do not fully tighten the bolt).
    2. Place the belt on the crankshaft pulley, then on the pump and camshaft pulley (observe the direction of rotation indicated by the arrows on the belt!).
    3. Tighten the tension roller bolt firmly 20–25 Nm.
    4. Turn the crankshaft to 2 full turns clockwise and check that the marks match.
    5. If the marks match, tighten the roller bolt completely (40–45 Nm).

    To check the belt tension, use special key (or long nose pliers). The correct tension is when the belt can be rotated 90° between the camshaft and crankshaft pulleys.

    💡

    On Almera G15 with motor HR16DE after 2016, the tension roller may have automatic mechanism - it does not need to be adjusted manually, but a check is required after 1000 km.

    Assembly and testing: how to avoid mistakes

    After installing the timing belt, reassemble everything in reverse order, but pay attention to the key points:

    • 🔧 Crankshaft pulley bolt tighten in 2 stages: first 50 Nm, then bring it to 100–120 Nm.
    • 🔩 Engine mount install only after complete assembly, so as not to warp the block.
    • 🚗 Antifreeze Fill through the upper radiator pipe to avoid air locks.
    • 🔍 Check engine operation at idle speed there should be no vibrations or extraneous sounds.
    ⚠️ Attention: After replacing the timing belt with Almera G15 avoid the first 500 km sudden acceleration and rpm above 3000 — the belt should “grind in” to the pulleys.

    If after starting the engine the Check Engine, check the error codes. Common mistakes after replacing the timing belt:

    • P0011 — camshaft phase shift (marks do not match).
    • P0340 — malfunction of the camshaft position sensor (check the connector).
    • P0300 - random misfires (may indicate incorrect belt tension).

    Common mistakes and how to avoid them

    Even experienced craftsmen sometimes make mistakes when replacing the timing belt with Nissan Almera G15. Here are the most common:

    1. Label mismatch due to the rotation of the camshafts after removing the belt. Solution: fix the shafts with gears or a special tool.
    2. Belt that is too tight or too tight. Solution: use a torque wrench and check the tension according to the manual.
    3. Using an old crankshaft pulley bolt. Solution: The bolt is disposable - always use a new one!
    4. Forgetting to replace the deflection roller. Solution: change all the rollers as a set, even if they “seem to be normal.”
    5. Oil on the belt due to a leaking crankshaft oil seal. Solution: check the oil seal and replace if necessary.

    Another typical problem is incorrect installation of the timing cover, causing her to rub against the belt. On Almera G15 The cover is attached to 4 bolts, and if it is skewed, the belt will wear out faster. Before final tightening of the bolts, check the gap between the cover and the belt (must be at least 5 mm).

    FAQ: answers to frequently asked questions

    Is it possible to replace only the timing belt and leave the old rollers?

    No, it's highly not recommended. The rollers wear out along with the belt, and if you leave the old ones, they can jam, which will lead to the breakage of the new belt. This is especially true tension roller - its bearing is often the first to “die”.

    Which timing belt is better to choose: original or analogue?

    Original belt (13028-4M51A) reliable, but expensive. Of the analogues, the best reviews are from:

    • Gates 5670XS — optimal price/quality ratio.
    • Contitech CT1179 - softer than the original, less noisy.
    • Dayco 94938 - tougher, but more durable.

    The main thing is to avoid cheap brands like Fenox or Finwhale, they often have problems with the resource.

    What happens if the timing belt breaks on a Nissan Almera G15?

    On the motor HR16DE (1.6 l) belt break 100% valve bend — this is a “plug-in” engine. Repairs will cost 80–120 thousand rubles (replacement of valves, grinding in, diagnostics). On HR15DE (1.5 l) the risk is lower, but also high. In both cases, the cylinder head may be damaged.

    Do I need to change the pump when replacing the timing belt?

    On Almera G15 the pump is driven by a timing belt, but its service life is usually 150–180 thousand km. If the pump does not leak or play, it is not necessary to change it. However, if the car's mileage is more than 100 thousand km, it is better to replace the pump prophylactically — its jamming also breaks the timing belt.

    Is it possible to drive with a cracked timing belt?

    No! Even small cracks on the outside of the belt indicate critical wear. The inner layers of the belt could already delaminate, and a break would occur at any moment. Replacement must be carried out immediately.
