Nissan Juke under the hood: photos, design and engine secrets

Under the hood Nissan Juke hiding not only the engine, but also a whole range of technical solutions that define the character of this compact crossover. Owners and potential buyers often ask questions: what does the engine compartment of different generations look like, where are the key components located, and what to look for during inspection? In this article we will look at the engine compartment Juke using the example of the most popular modifications, we will provide current photo with captions, and also reveal the nuances that even the official manuals are silent about.

Feature Nissan Juke — its non-standard layout under the hood, due to the front-wheel drive platform Nissan B (for the first generation) and modular architecture CMF-B (for the second one). There is no usual symmetry here: the battery may be located under the trunk floor, and the expansion tank may be in an unexpected place. If you are planning to do the maintenance yourself or just want to understand the car, this article will become your guide. We will also compare the engine compartments of petrol and diesel versions, point out typical problems and give advice on diagnostics “by eye”.

Photo of the engine compartment of Nissan Juke: general view and key components

Let's start with a visual acquaintance. Below are real photos engine compartment Nissan Juke first (F15, 2010–2019) and second (F16, from 2019) generations. Pay attention to differences in layout - they affect the accessibility of components during repair.

📌 Nissan Juke F15 (2010–2019) with HR16DE engine (1.6 l, 117 hp):

• 🔋 Battery — located under the trunk floor (on the right), access through the hatch in the cabin.
• 🛢️ Oil filler neck — on the right (in the direction of travel), closed with a black lid with the inscription 1.6.
• 🔥 Ignition coils — hidden under the decorative engine cover (removal required to replace spark plugs).
• 💧 Coolant expansion tank — on the left, next to the shock absorber strut.

📌 Nissan Juke F16 (from 2019) with HRA0 engine (1.0 l, turbo, 117 hp):

• 🔋 Battery — moved to the engine compartment (left), but access is complicated by the air duct.
• 🌀 Turbocharger — located on the right, next to the exhaust manifold (requires cooling after a trip!).
• 🛢️ Oil filler neck — moved closer to the windshield, the cover is yellow.
• ⚡ Fuse box — is now located under the cover next to the battery.

🔍 What do both generations have in common? Regardless of the engine, under the hood Juke always crowded: engineers Nissan sacrificed ease of maintenance for compactness. For example, Replacing spark plugs on HR16DE requires removing the intake manifold, which takes up to 3 hours in the service.

Location of the main elements under the hood: diagram and description

In order not to get confused in the intricacies of tubes and wires, we have compiled interactive diagram engine compartment Nissan Juke with the designation of key nodes. For convenience, we divide them into groups:

Knot	Location (F15)	Location (F16)	Notes
Battery	Under the trunk floor	Left in the engine compartment	On F16, access is complicated by the air duct
Oil filler neck	Right, black cover	Left, yellow cover	On F16 the neck is higher, it is more convenient to fill in oil
Coolant expansion tank	Left, at the counter	On the left, but closer to the center	On F16 the tank is transparent, with marks MIN/MAX
Fuse box	Inside, to the left of the steering wheel	Under the hood, next to the battery	On F16 the block is divided into 2 parts
Turbocharger	Missing	On the right, next to the collector	Requires cooling after the trip!

⚠️ Attention: On diesel versions Nissan Juke (engine K9K) under the hood added diesel particulate filter (DPF) and system AdBlue (if any). Their location varies depending on the year of manufacture. For example, on restyled F15 models (after 2014) the tank AdBlue moved under the spare tire, and the level sensor - in the trunk.

💡 Advice: Before any work under the hood Juke be sure to take it off decorative engine cover (it is secured with 4 latches). Underneath it are hidden the ignition coils, valve cover and part of the fuel system. On turbo engines HRA0 the lid also prevents access to intercooler.

Nissan Juke engines: features and pitfalls

Nissan Juke was equipped with several types of engines, each of which has unique features - both positive and problematic. We will analyze them in detail so that you can assess the risks when purchasing or using them.

🔹 HR16DE (1.6 l, 117 hp) - atmospheric gasoline:

• ✅ Pros: Simplicity of design, reliability (with timely maintenance), absence of a turbine.
• ❌ Cons:
  • 🔥 Timing chain problems — stretches to 150–200 thousand km, requires replacement with tensioners.
  • 💧 Oil leaks through the valve cover and crankshaft oil seal (especially on runs over 100 thousand km).
  • ⚡ Ignition coils — they fail every 60–80 thousand km (symptom: tripping when cold).

🔹 HRA0 (1.0 l, turbo, 117 hp) - modern turbo engine:

• ✅ Pros: Efficiency (consumption 5.5–6.5 l/100 km), dynamics thanks to the turbine, compliance with eco-standards Euro 6d.
• ❌ Cons:
  • 🌀 Turbocharging - sensitive to oil quality (synthetics required 5W-30 with permission Nissan).
  • 🔥 Overheating - due to the compact radiator and cramped engine compartment.
  • 🛑 Expensive repairs — replacing a turbine or intercooler costs 100–150 thousand rubles.

🔹 K9K (1.5 l, diesel, 110 hp) - rare version for Europe:

• ✅ Pros: Low consumption (4.5–5.5 l/100 km), high torque (260 Nm).
• ❌ Cons:
  • 🚫 Diesel Particulate Filter (DPF) — gets clogged during city use and requires cleaning every 80–100 thousand km.
  • 💰 AdBlue system - costs 20–30 thousand rubles when replacing a tank or sensor.
  • ❄️ Starting problems in winter — glow plugs fail every 3–4 years.

⚠️ Attention: If you are considering Nissan Juke with mileage, be sure to check service history for changing oil and timing chain. On naturally aspirated engines HR16DE oil change interval - every 15 thousand km, on turbo engines HRA0 — every 10 thousand km. Missing even one replacement can lead to oil starvation of the turbine and its failure.

How to independently diagnose problems under the hood?

It is not always possible to contact service, especially if the malfunction appears on the way. We have collected list of symptoms and methods for diagnosing them “by eye” and “by ear”, which will help identify problems under the hood Nissan Juke without special equipment.

🔍 Visual inspection:

• 💧 Oil leaks - check:
  • Valve cover (gasket often leaks).
  • Crankshaft oil seal (oil on crankcase protection).
  • Turbine (at HRA0 — oil on the intercooler).
• 🔥 Overheat: if the temperature gauge is over 90°C, check:
  • Coolant level (reservoir should be between MIN And MAX).
  • Fan operation (should turn on when warming up to 100°C).
  • Condition of the radiator (clogged honeycombs or leaks).
• ⚡ Electrical: oxidation of battery terminals, melted fuses, cracked wires.

👂 Sound diagnostics:

• 🔊 Knock on startup — the timing chain may wear out (on HR16DE) or piston group.
• 🌀 Whistle when revving up - turbine malfunction (at HRA0) or alternator belt.
• 💥 Popping sounds in the exhaust system — the manifold gasket is burnt out or there are problems with the ignition.

🛠️ Practical tips:

1. To check the timing chain for HR16DE Remove the valve cover and check the alignment of the marks on the sprockets.
2. On HRA0 After the trip, let the turbine idle for 1-2 minutes - this will extend its life.
3. If the engine stalls, swap the ignition coils - if the cylinder has changed, the coil is to blame.

How to check compression without a compression gauge?

If you don’t have a tool, you can roughly estimate the compression by eye:

1. Unscrew all spark plugs.

2. Crank the engine with the starter (without starting).

3. If the air coming out of one cylinder is weaker, there is low compression (perhaps wear of the rings or valves).

Attention: the method is not accurate, but it will help identify obvious problems.

Nissan Juke maintenance: what can you do yourself?

Despite the tightness under the hood, some of the maintenance work Nissan Juke you can do it yourself. We have compiled step by step instructions for the most common procedures, taking into account the nuances of each generation.

🔧 Changing the oil and filter (for HR16DE):

1. Warm up the engine to operating temperature (the oil will become less viscous).
2. Remove the crankcase protection (4 bolts on 10 mm).
3. Unscrew the drain plug (key on 14 mm) and drain the oil into a container.
4. Replace the oil filter (located on the right, next to the pan).
5. Fill in new oil through the filler neck (volume: 4.3 l for HR16DE, 4.0 l for HRA0).

⚠️ Attention: On HRA0 The oil filter is integrated into the housing - a special puller is required. Also after changing the oil be sure to reset the service interval via the on-board computer menu:

Настройки → Техническое обслуживание → Сброс

🔋 Battery replacement (for F16):

• Disconnect the negative terminal (key on 10 mm).
• Remove the air duct (snap off the 2 clips).
• Unscrew the battery mount (bolt on 12 mm).
• Install a new battery (recommended capacity: 60–70 Ah).
• Reset the electronics (open/close the door, turn on the ignition for 10 minutes).

💡 Replacing the air filter:

On both generations, the filter is located in a plastic housing on the right (in the direction of travel). To replace it:

1. Unhook the 4 clips on the housing cover.
2. Remove the old filter (pay attention to the direction of the arrow on it!).
3. Install a new filter (for example, Mann C 25 026 or Framm CA 10166).
4. Check the tightness of the case - air leaks lead to an error P0171 (lean mixture).

📌 Advice: When replacing the air filter with HRA0 inspect pipe from turbine to intercooler - it often cracks, which leads to loss of boost.

Typical mistakes owners make when working under the hood

Even experienced car owners sometimes make mistakes that lead to expensive repairs. We have collected TOP 5 most common mistakes during maintenance Nissan Juke and explained what they lead to.

🚫 Mistake 1: Ignoring the oil level between changes

Many people check the oil only before changing it, but HRA0 its level can drop to critical within 5–7 thousand km (due to the turbine). Consequences: oil starvation, bearing wear, turbine jamming.

🚫 Mistake 2: Using non-original spark plugs

On HR16DE Cheap candles are often used (for example, Bosch instead of NGK IFR6T11). Consequences: tripping, misfire, error P0300.

🚫 Error 3: Incorrect tightening of bolts

When replacing the crankcase protection or drain plug, many people overtighten the bolts. Consequences: broken threads in the pan (repair - welding or replacement of the pan).

🚫 Mistake 4: Neglecting to clean the radiator

On Juke The radiator quickly becomes clogged with lint and dirt (due to its compact location). Consequences: engine overheating, fan failure.

🚫 Error 5: Replacing the timing chain yourself without marks

On HR16DE The chain is changed without marking it “by eye”. Consequences: phase displacement, collision of pistons with valves, major repairs.

⚠️ Attention: If you have never worked with Nissan Juke earlier, start with simple procedures (changing filters, oil). For complex work (timing chain, turbine), it is better to contact a service center - saving on repairs can result in even greater expenses.

⚠️ Attention: Any tuning associated with changing engine parameters (chip tuning, turbine replacement) can lead to refusal of warranty service (if the car is under warranty) or problems during maintenance. Also keep in mind that more than 20% increase in power requires re-registration with the traffic police.

FAQ: Frequently asked questions about the engine compartment of Nissan Juke

🔧 Where is the engine number on Nissan Juke?

On HR16DE the number is stamped on the cylinder block right (transmission side), next to the thermostat. On HRA0 - on the front of the block, under the turbine. For inspection you will need a mirror and a flashlight.

🛢️ What oil should I put in my Juke engine?

Official recommendations Nissan:

• HR16DE: 5W-30 or 5W-40 (tolerance API SN, ILSAC GF-5).
• HRA0: only 5W-30 (tolerance Nissan Strong Save X E or ACEA C2).
• K9K (diesel): 5W-30 (tolerance ACEA C4, MB 229.51).

Oil volume:

• HR16DE: 4.3 l (with filter replacement).
• HRA0: 4.0 l.
• K9K: 4.8 l.

⚡ Why is the oil pressure light on on a Juke with an HRA0 engine?

There are several reasons:

1. Low oil level - check with a dipstick.
2. Faulty oil pump - requires diagnostics.
3. Clogged oil filter - replace with a new one.
4. Wear of crankshaft bearings - critical, requires repair.
5. Oil pressure sensor malfunction - check with a multimeter.

🔴 Important: If the lamp flashes at idle, immediately turn off the engine and do not start until the cause is eliminated!

🌀 How to check the turbine on a Nissan Juke HRA0?

Take the test:

1. Start the engine and let it warm up.
2. Press the gas sharply to 4–5 thousand rpm.
3. Listen to the sound of the turbine:
   • 🔊 Whistling — air leakage (check the pipes).
   • 💥 Grinding — bearing wear (replacement required).
   • 🔇 No sound — the turbine does not spin up (check the vacuum hoses).

Inspect the intercooler for the presence of oil (if there is, the turbine “drives” oil).

📌 Advice: For an accurate diagnosis, measure the boost pressure (normal: 0.8–1.0 bar at 3 thousand rpm).

🔋 Why does the Juke battery drain quickly?

Common reasons:

• Leakage current — check with a multimeter (norm: up to 50 mA).
• Faulty generator - measure the voltage at the terminals (should be 1
