BelGEE S50: what engine is under the hood and how to choose it correctly?

Company BelGEE (joint venture GEELY and BelAZ) released the model BelGEE S50 as an affordable alternative to Chinese and European crossovers. This car attracted attention not only with its design, but also with its reliable power units. However, potential buyers and owners often have a question: what engine is on the BelGEE S50, what are its characteristics and how does it perform in operation?

In this article we will analyze all the engine options that were installed on BelGEE S50 in different years, their technical parameters, service features and typical problems. You will also learn how to determine the type of engine by VIN code, what oils and spare parts are suitable for replacement, and what to consider when buying a used car. If you are planning repairs or tuning, here you will find useful recommendations from experts.

All BelGEE S50 engines: official versions and their differences

During production (from 2017 to 2023) BelGEE S50 was completed three main types of engines, two of which are petrol and one is diesel (for some markets). All of them are developed on the basis of units Geely, but adapted to local operating conditions. Let's consider each option in detail.

Important: BelGEE S50 has never been equipped with hybrid or electric powertrains - all engines are exclusively internal combustion engines. It is also worth noting that after 2020, the diesel version was no longer supplied to Russia and Belarus due to changes in environmental standards.

• 🔧 1.5L JL4G15 (gasoline, 109 hp) — base engine for most trim levels. Atmospheric, with distributed injection, meets the standard Euro 5.
• ⚡ 1.8L JL4G18 (gasoline, 133 hp) - a more powerful version with improved dynamics. Also naturally aspirated, but with a modified gas distribution system.
• ☁️ 1.5L JLD-4G15 (diesel, 105 hp) - economical option for commercial use. Turbocharged, with system Common Rail.

The most common on the secondary market is 1.5 liter petrol engine - it was installed on 70% of cars produced. The diesel version is extremely rare and mainly among corporate clients.

Technical characteristics of BelGEE S50 engines in comparison

To understand which engine is best suited for your needs, let's compare their key parameters. Below is a table with basic technical data. Please note power, torque and fuel consumption - these are critical indicators when choosing.

Parameter	1.5L JL4G15 (petrol)	1.8L JL4G18 (petrol)	1.5L JLD-4G15 (diesel)
Volume, cm³	1498	1794	1498
Power, hp (kW)	109 (80)	133 (98)	105 (77)
Torque, Nm	140 at 3800 rpm	170 at 4200 rpm	235 at 1800–2600 rpm
Fuel consumption (combined cycle), l/100 km	6.8	7.2	5.1
Fuel type	AI-92/AI-95	AI-95	DT (Euro-5)

Critical point: the diesel version of the JLD-4G15 requires mandatory replacement of the timing belt every 60,000 km, while gasoline engines can travel up to 90,000 km without replacement (according to factory regulations). Neglect of this rule leads to belt breakage and valve bending - repairs will cost 150–200 thousand rubles.

If acceleration dynamics are important to you, choose 1.8 liter engine — it provides better traction at high speeds. To save fuel, a diesel engine is suitable, but keep in mind that its maintenance is more expensive due to the specifics of the fuel system Common Rail.

How to determine which engine is in your BelGEE S50?

There are several reliable ways to find out the type of engine without looking under the hood. The most accurate - check by VIN code. It is indicated on the registration certificate (CTC) or on a plate under the windshield. In the VIN the engine is coded 8th character:

• 🔢 5 — 1.5L JL4G15 (gasoline)
• 🔢 6 — 1.8L JL4G18 (gasoline)
• 🔢 D — 1.5L JLD-4G15 (diesel)

The engine type can also be determined by:

1. Sticker under the hood - there is usually a marking on the valve cover or cylinder block (for example, JL4G15).
2. Car documents — the engine size and model are indicated in the vehicle title or service book.
3. External signs:
   • 🔍 Diesel has turbocharger (visible from the pipes) and the fuel filter under the hood.
   • 🔍 The 1.8-liter petrol engine is different increased block size and other location of the generator.

Where else can I find information about the engine?

If the VIN code is erased or documents are lost, try:

1. Request data from the traffic police (through the government services portal).

2. Contact an official BelGEE dealer with the body number.

3. Use a diagnostic scanner (for example, ELM327) to read information from the ECU.

⚠️ Attention: On the secondary market there are altered VIN numbers or “reflashed” ECUs, where engine data may be fake. Before purchasing, be sure to check the markings on the cylinder block with the documents!

For gasoline engines it is critical to use approved oil API SN or ILSAC GF-5. For diesel - standard required ACEA C3 or API CJ-4.

⚠️ Attention: Never mix oils of different manufacturers or types (for example, synthetic with semi-synthetic). This leads to the formation of sediment and blockage of oil channels, which leads to oil starvation and engine wear.

Tuning and modifications of BelGEE S50 engines: what can be done?

If standard power isn't enough for you, there are several ways to improve engine performance. Let's consider the most effective and safe options.

For gasoline engines (1.5L and 1.8L)

• 🔧 Chip tuning — flashing the ECU to increase power by 10–15%. Cost: 15–25 thousand rubles. Recommended firmware: Malpassi or Dimsport.
• 🔧 Installing a direct exhaust manifold (spider) — improves exhaust gas removal, adds 5–7 hp. Cost: 8–12 thousand rubles.
• 🔧 Replacing the air filter with a zero filter - for example, K&N 33-2304. Adds 3-5 HP, but requires frequent cleaning.

For diesel engine (1.5L)

• 🔧 Intercooler installation — reduces the temperature of the charge air, increases power by 10–12 hp. Cost: 25–35 thousand rubles.
• 🔧 ECU firmware for Euro-2 — removes restrictions on the particulate filter, adds 15–20 hp. Minus: the car will not pass inspection.
• 🔧 Replacing the turbine with a more efficient one - for example, Garrett GT1544. Increase: up to 20–25 hp, but requires modification of the exhaust system.

⚠️ Attention: Any engine tuning removes the car from warranty (if it is still active) and can lead to accelerated wear details. For example, chip tuning without strengthening the transmission often leads to gearbox failure.

What happens if you install a turbine on a 1.5-liter gasoline engine?

Such a modification is possible, but will require:

1. Reinforcement of the piston group (replacement with a forged one).

2. Installation of intercooler and oil cooler.

3. Complete flashing of the supercharged ECU.

Cost of work: 150–200 thousand rubles. In this case, the engine life will be reduced to 100–150 thousand km.

FAQ: Frequently asked questions about BelGEE S50 engines

Is it possible to put 92-octane gasoline into a 1.8-liter engine?

The manufacturer officially recommends AI-95, but short-term use of the 92nd is acceptable. However, if you constantly drive on 92 gasoline, it is possible detonation, which leads to wear of the piston group. If there is no choice, add an additive Liqui Moly Oktan Plus (1 bottle per 50 liters of fuel).

What is the service life of BelGEE S50 engines?

With proper maintenance:

• 1.5L petrol - 250–300 thousand km;
• 1.8L petrol - 300–350 thousand km;
