The first thing that greets the owner when opening the hood Skoda Yeti, is an amazing layout for a car of this class. Despite the compact dimensions of the body, engineers have accommodated powerful power units and a complex cooling system typical of larger VAG models. Understanding exactly where key components are located is critical for self-service and quick troubleshooting on the road.
Many beginners mistakenly believe that under the hood Yeti everything is simple and accessible. In fact, especially in versions with turbocharged engines, access to some elements may be difficult due to plastic casings and dense hoses. Regular inspection engine compartment allows you to detect oil or antifreeze leaks at an early stage, which will save you from expensive engine repairs.
General layout and location of main components
Looking at the engine compartment Skoda Yeti The dominance of the power unit in the center is immediately noticeable. In front, behind the radiator grille, are the main heat exchangers, and on the sides are fluid tanks. The right side (passenger side) typically houses the battery and fuse box, while the left side houses the intake components and throttle body.
A special feature of the design is the presence of a voluminous plastic casing covering the upper part of the engine. This element not only performs an aesthetic function, but also reduces noise levels and also protects parts from dust and moisture. However, to check the spark plugs or the condition of the drive belts, it will have to be removed, which requires care not to break the plastic clips.
It is important to note that the location of the components may vary slightly depending on the type of engine: naturally aspirated 1.6 MPI, turbocharged 1.2 TSI or diesel 2.0 TDI. In diesel versions, there is also a coarse fuel filter under the hood, which requires regular replacement and drainage.
- 🔧 The fuse and relay box is located in the right niche, behind the decorative cover.
- 🌡️ The coolant expansion tank has a distinctive black cap with pressure markings.
- 🔋 The battery is located in a special compartment, access to which often requires removing plastic covers.
Cooling system and liquid levels
Cooling system Skoda Yeti works in harsh conditions, especially when operating in off-road conditions or in the summer heat. Expansion tank is a key element for visual monitoring of antifreeze levels. The fluid level should be between the marks MIN and MAX on a translucent flask. If the level drops, it may indicate a faulty radiator, pump or head gasket.
When checking the cooling system, it is necessary to take into account that opening the reservoir cap on a hot engine is strictly prohibited due to high pressure in the system. This can result in serious burns from steam or boiling antifreeze. Always allow the engine to cool to a safe temperature before handling the cap in any way.
Owners of diesel versions should pay special attention to the condition of the pipes, as engine vibration 2.0 TDI may loosen the clamps over time. You should also regularly inspect the radiator for contamination with lint, leaves or dirt, which critically affects cooling efficiency.
⚠️ Attention: Mixing antifreeze of different colors or types in the cooling system Skoda Yeti may cause sludge formation and engine overheating. Always use fluid meeting the G12++ or G13 specification.
To monitor the tightness of the system, it is useful to know what the normal condition of the pipes looks like. They must be elastic, without cracks or signs of leakage at the joints with the engine. Any oil stains on the surface of rubber hoses are a signal for immediate replacement.

Electrics, battery and charging system
Electrical system Skoda Yeti includes not only a standard set of wires, but also complex control units located in the engine compartment. Battery in most configurations it is located in a hard-to-reach place, which complicates the replacement procedure. However, this is where the main power connectors and starter relays are located.
The generator, driven by the belt of the attachment equipment, is located at the bottom of the engine. Checking its operation is usually reduced to measuring the voltage at the terminals of the battery when the engine is running. The normal level should be in the range of 13.8 up to 14.5 volts. Deviations may indicate a malfunction of the diode bridge or voltage regulator.
Particular attention should be paid to the state of terminals and contacts. In conditions of high humidity and road salt, oxidation of contacts is possible, which leads to poor engine start-up. Regular cleaning and lubrication of terminals with special compounds will prolong the life of the electrical system.
- 💡 Check the integrity of the insulation on the high-voltage wires of the ignition coils.
- 🔌 Examine sensor connectors, especially mass air flow (MARD), for moisture.
- 🛡️ Make sure that the plastic battery protection is not damaged or touches the terminals.
Where is the engine control unit (EBU) located?
The engine control unit (ECU) in the Skoda Yeti is most often located in a niche next to the battery, behind a protective plastic casing. Access to it is limited, but necessary for diagnosis and flashing.
Maintenance: Filters and Belts
Regular maintenance of the under-hood space Skoda Yeti includes the replacement of air, cabin and fuel filters, as well as the inspection of drive belts. Air filter It is in the plastic body to the right of the engine. Its replacement is simple and does not require special tools, it is enough to unfasten the latches and remove the old element.
The attachment belt, which drives the generator, hydraulic power pump and air conditioner, requires careful inspection for cracks and stratification. The tension of the belt is regulated by an automatic tensioner, which also needs to be checked for backlashes and wear of the bearing. When a whistle appears when starting the engine or working at idle speeds, most likely, the problem is in the belt.
Replacing the fuel filter is critical for diesel engines, as the quality of diesel fuel in some regions leaves much to be desired. A clogged filter can lead to loss of power and difficult start-up. In gasoline versions with direct injection, it is also important to monitor the state of the fuel ramp and injectors.
☑️ Planned maintenance of the under-hood space
Do not forget about the spark plugs. Although access to them is often blocked by plastic parts, replacing them is a must-have procedure to maintain optimal fuel consumption and vehicle dynamics. For engines TSI This is especially true, since turbocharged engines are sensitive to the quality of spark formation.
Ventilation system and heater
In the rear part of the hood space, at the partition of the engine compartment, there is a heater body and a ventilation system of the cabin. This is where the cabin filter is located, which cleans the air entering the car. Clogging of this element can lead to fogging of glasses and reduce the efficiency of the oven in winter.
Temperature and pressure sensors located in this zone transmit data to the climate control unit. Any mechanical damage to the sensors or their contamination can lead to incorrect operation of the air conditioning system. It is important to monitor the integrity of the corrugated ducts to avoid foreign objects entering the system.
Also in this area are air conditioning tubes, which can be subject to vibration wear. Checking for traces of oil in the joints of the tubes will help to detect a leak of refrigerant in time. Leaking freon not only deprives you of air conditioning, but can also damage the compressor.
⚠️ Note: Do not try to refuel the air conditioner yourself without checking the system for leakage. Moisture entering the circuit can destroy the compressor and require a complete replacement of the unit.
Visual inspection for leaks and damage
Regular visual inspection is the easiest and most effective way to prevent serious breakdowns. Oil leaks often appear in the connection of the pallet of the crankcase with the cylinder block or around the crankshaft. Oil traces at the bottom of the engine compartment or on the suspension details may indicate an engine problem.
Pay special attention to the condition of the radiator body and expansion tank. Cracks in plastic, especially in the attachment sites of the pipes, can lead to a sudden loss of coolant. In winter, the risk of rupture of plastic parts increases due to the expansion of the freezing liquid.
During the inspection, also check the condition of the exhaust gas recirculation system (EGR) hoses and vacuum tubes. These elements are often exposed to high temperatures and become brittle over time. Failure of vacuum tubes can lead to unstable operation of the engine at idle speeds.
