In the history of the domestic automotive industry of the early 2000s Tagaz Tager It's a very special place as an attempt to create an affordable SUV with a recognizable design. SsangYong KorandoThe car was the first acquaintance of many Russians with a frame SUV of the budget segment, the heart of which was a gasoline power unit, which, despite its simplicity, required careful attention from the owner to ensure long service.
The main source of energy for all modifications was engine D23DTThis is a 2.3-liter atmospheric four-cylinder engine that was originally designed to meet the harsh conditions of use, and in those years, the presence of an injection system was already considered the standard, but it was the simplicity of the design that allowed it to be repaired in the field, which was critical for remote regions.
As it becomes increasingly difficult to find a working unit, understanding the technical nuances of the power unit comes to the fore. Many owners face a shortage of original parts, which forces them to look for alternative solutions or engage in deep restoration of existing units. Competent diagnosis and knowledge of weak points allow you to extend the life of the unit and avoid expensive overhaul.
Technical specifications of the power unit
Basic D23DTThe TAGAZ Tager has a four-cylinder inline layout, with a displacement of 2,295 cubic centimeters, which allows for 141 horsepower at 5,500 rpm, torque of 210 Nm in the range of 4000-4,500 rpm, which provided acceptable dynamics for a car with a framed structure and plug-in all-wheel drive.
The cylinder head design includes two camshafts and 16 valves, which was the cutting edge solution for a budget SUV of the time. The power system operates on a multipoint distributed fuel injection controlled by an electronic unit. The gas distribution mechanism is driven by a gear belt, which requires strict adherence to replacement regulations to avoid a cliff.
⚠️ Attention: When the timing belt breaks, the valves are bent on this engine, which leads to expensive repairs to the cylinder head.
The engine cooling system is pressurized and equipped with a thermostat, which often causes overheating when failure occurs. It is important to monitor the condition of the pipes and radiator, since the vibrations characteristic of frame SUVs can lead to their rapid wear.
Replace antifreeze strictly according to the regulations and use only the recommended types of coolant, as mixing different compositions can lead to the formation of precipitation and corrosion of cooling channels.
Design features and device
The cylinder block is made of cast iron, which ensures high strength and maintainability, can be squandered if necessary to maintain the size of the engine, which prolongs the life of the engine even after serious damage to the cylinder-piston group. The knead shaft is forged, installed on five support necks, which ensures stable operation of the crank-shaft mechanism at high loads.
The intake manifold is made of aluminum alloy and has complex geometry to optimize cylinder filling. However, over time, the channels can accumulate charcoal, especially when using low-quality fuel. Regular cleaning of the throttle and intake tract helps to maintain thrust at the proper level.
The ignition system is based on individual coils for each candle, which increases the reliability of spark formation. ignition candles require selection with the correct potassium number specified in the technical documentation. Incorrectly selected candles can cause detonation or potassium ignition, which destroys pistons.

Typical malfunctions and methods of their elimination
One of the most common problems is idling instability, often caused by contamination of the idler regulator or the sucking of unaccounted air through cracks in the intake manifold, and the diagnosis begins with checking the intake tract tightness and cleaning the sensors.
Another common problem for TagAZ Tager owners is the failure of the crankshaft position sensor. When it fails, the engine stalls and stops starting, as the ECU loses synchronization. It is recommended to always have a spare sensor in the trunk, especially on long trips.
Oil leaks are also not uncommon in the age group, butter can seep through the valve cover glands, the GBC gasket, or the front crankshaft oal, and timely replacement of the seals prevents oil levels from falling and subsequent oil starvation.
⚠️ Note: Operation of the engine with oil level below the minimum mark on the probe is strictly prohibited, as this leads to the twisting of the liners and bullies in the cylinders.
Cooling problems often involve jamming the thermostat in the closed position, which leads to rapid boiling of antifreeze and deformation of the cylinder head, and at the first sign of overheating, you need to stop and check the circulation of fluid in the system.
Fuel consumption and economy
The issue of fuel efficiency for TagAZ Tager is quite acute, given its aerodynamics and weight. In a combined cycle, the engine consumes from 11 to 13 liters of AI-92 gasoline per 100 kilometers. In urban mode with frequent traffic jams, the consumption can reach 14-15 liters, which should be considered when planning the budget for maintenance.
On the road at 90-100 km/h, you can reduce the consumption to 9-10 liters. However, increasing the speed to 120 km/h and above dramatically increases the aerodynamic drag, and the flow rate increases again. Driving style also plays an important role: sharp acceleration significantly increases the appetite of the engine.
Factors affecting fuel consumption
Not only are the engine's technical parameters affected, but the chassis condition is also affected, and jammed brake calipers, incorrectly exposed wheel-declination angles and deflated tires can increase fuel consumption by 15-20%.
Using higher octane gasoline, such as the AI-95, does not produce significant power gains, but it may slightly improve the elasticity of the engine at high revs. However, it is more cost-effective to use quality AI-92 from proven suppliers.
Maintenance and replacement of consumables
Regular maintenance is key to the longevity of the TagAZ Tager engine. The engine oil should be replaced every 8-10 thousand kilometers, since in active operation and dusty roads, the degrade oil properties are faster.
The filter element of the oil filter must be changed with each oil change. The air filter is checked every 5,000 km and changes as the vehicle is polluted, especially if the vehicle is operated in dusty conditions. A clogged air filter leads to the mixture being over-enriched and power drops.
The belt requires replacement every 60,000 kilometers or every 4 years, whichever comes first, and the tension roller and pump change with the belt, because their life is about the same.

Opportunities of tuning and refinement
There are several ways for owners to upgrade to improve their performance, and the chip-tuning system can adjust their performance by removing low-speed dips and increasing power slightly, but it's not a miracle, because the atmospheric motor has physical limitations in the air.
A more radical method is to install a turbocharging, but it requires serious intervention in the design: replacing the piston group with a forged one, installing an intercooler and flashing the brains, which must be performed by qualified specialists, otherwise the engine life will fall to a minimum.
A simple but effective way to improve performance is to install a direct-flow exhaust and a zero-resistance filter, which will make it a little easier to breathe at high speeds and add a nice sound, but at low speeds, the effect may be invisible or even negative due to the loss of exhaust inertia.
