The ŠKODA Kodiaq is one of the most popular crossovers in Russia, but even such a reliable car requires regular maintenance. Cooling liquid (antifreeze) is not just a consumable, but a critical component on which the life of the engine, gearbox and even the heating system of the cabin depends. An error in the choice or untimely replacement can result in overheating, corrosion of aluminum parts or failure of the pump.
In this article we will look at Official ŠKODA Antifreeze Requirements for Kodiaqincluding specifications VW TL 774-G and G13Volumes for different engines (1.5 TSI, 2.0 TSI, 2.0 TDI), as well as the nuances of replacement - from draining old liquid to pumping the system. We will also focus on the myths (for example, “Can G12++ and G13 be mixed?”). Unique recommendations for the selection of analogues that will not lead to loss of warranty.
Official antifreeze specifications for ŠKODA Kodiaq
The manufacturer clearly regulates what antifreeze can be poured into Kodiaq These are liquids that meet the standard VW TL 774-G. Under this designation there are two types of coolants:
- 🔹 G12++ (purple) - a hybrid formula based on ethylene glycol with organic and inorganic additives. Suitable for all gasoline and diesel engines Kodiaq until the 2018 release.
- 🔹 G13 (yellow or orange) - an evolutionary version with the addition of glycerol, more environmentally friendly and durable. It is recommended for cars from 2019, but it is compatible with older models.
Important: The color of antifreeze is non-indicator of compatibility. For example, some brands (for example, Motul or Liqui Moly) produce G13 in blue. The main thing is the availability of a certificate VW TL 774-G on the packaging.

- Analogue (Motul, Liqui Moly)
- G12++ (purple)
- I don't know what's in there
- Other
ŠKODA also allows the use of original antifreeze. VW G13 (article G 013 A8J M1) which is sold in concentrated form (diluted with 1:1 distilled water) or ready-to-use liquid. The cost of the original is higher than its counterparts, but it is guaranteed to meet all the requirements of the manufacturer.
⚠️ Attention: Antifreeze G11 (green) and G12 (Red) is strictly prohibited for Kodiaq. Their additives are incompatible with aluminum parts of modern engines.EA888andEA288This leads to corrosion and blockage of the cooling system channels.
Antifreeze volume for different ŠKODA Kodiaq engines
Total volume of cooling system Kodiaq It depends on the type of engine and the availability of additional options (for example, engine heater). Below is a table with exact data:
| Engine | System volume (l) | Recommended antifreeze | Notes |
|---|---|---|---|
1.5 TSI (150 hp) DADA) |
6.5–7.0 | G13 (VW TL 774-G) | With engine heating - +0.5 liters |
2.0 TSI (190/245 hp), DKXA/DLBA) |
7.5–8.0 | G13 or G12++ | For the RS version (245 hp) – only the G13 |
2.0 TDI (150/190/240 hp), DFGA/DBGA) |
8.0–8.5 | G13 | Diesel engines are more sensitive to antifreeze quality |
When completely replacing antifreeze, keep in mind that only ~80-90% of the liquid is drained - the residues remain in the engine unit and the heater radiator. For full-wash Special equipment will be required (e.g., the device) HEPU P901) which is on the official STO.
If you don’t know which antifreeze was previously filled, use it. VW G13 - It's compatible with G12++ It won't cause a chemical reaction. But before the pour, be sure to check the level in the expansion tank on a cold engine!
When to change antifreeze in a ŠKODA Kodiaq: regulations and signs of wear
ŠKODA regulations require replacement of antifreeze every time 5 years or 250,000 km (Depending on what comes first.) However, these terms are only relevant to the original VW G13. For analogues (for example, Febi 32600 or Ravenol J1A2001) the interval shall be reduced to 3–4 years or 150,000 km.
Signs that antifreeze requires urgent replacement:
- 🔥 A darkening or turbidity of the liquid (indicates the breakdown of additives).
- 💨 The appearance of sediment or flakes in the expansion tank.
- 🌡️ Frequent engine temperature jumps (especially in traffic jams).
- 🚗 The smell of burns or sweetish aroma in the cabin (leakage through the stove).
If these symptoms are ignored, the consequences can be critical, from overheating of the cylinder head to the destruction of pump bearings. For example, in engines. 2.0 TSI (EA888 Gen3) overheating often leads to deformation of the aluminum cylinder head, the repair of which costs 150–200 thousand rubles.
What happens if you don't change the antifreeze?
Old coolant loses its anti-corrosion properties, which leads to the formation of scale on the walls of the channels. This impairs heat transfer, increases the load on the water pump and can cause the thermostat to jam. In diesel Kodiaq (for example, 2.0 TDI) Contaminated antifreeze often causes failure of the exhaust gas recirculation (EGR) system.
Step-by-step instructions for replacing antifreeze in a ŠKODA Kodiaq
Replacing antifreeze with Kodiaq requires accuracy and consistency. You will need:
- 🛠️ New antifreeze (8–10 liters for a complete replacement).
- 🔧 Set of wrenches (13mm socket for drain plug).
- 💧 Distilled water (5–10 liters for rinsing).
- 🧤 Gloves and container for draining (minimum 10 l).
Algorithm of actions:
- Draining old antifreeze:
- Place the car on a level surface and let the engine cool.
- Remove the engine protection (4 x 13 bolts).
- Place a container under the drain plug on the radiator (lower left corner) and unscrew it.
- Open the expansion tank cap to speed up draining.
- Flushing the system (optional if antifreeze is heavily contaminated):
- Close the drain plug and fill with distilled water.
- Start the engine and let it idle for 5-10 minutes.
- Drain the water and repeat the procedure 2-3 times.
- Refilling with new antifreeze:
- Tighten the drain plug and fill in new antifreeze through the expansion tank.
- Start the engine, turn the heater on to maximum and add fluid to the level
MAX. - Bleed the system by squeezing the radiator pipes (this will remove air pockets).
Make sure the engine is cool (temperature < 50°C)|Prepare a container for drainage (≥10 l)|Buy antifreeze with VW TL 774-G certificate|Check the integrity of the pipes and clamps|Have distilled water on hand for flushing-->
After replacement, check the antifreeze level after 1–2 days of operation. If it drops, top it up to normal - this is normal, since the air does not completely leave the system immediately.
⚠️ Attention: On Kodiaq with engines 2.0 TSI (EA888 Gen3) after replacing the antifreeze, be sure to reset the adaptations of the engine control unit via a diagnostic scanner (for example, VCDS or ODBEleven). Otherwise, false errors in the cooling system are possible.
Top 5 analogs of original antifreeze for ŠKODA Kodiaq
Original VW G13 costs ~1,500–2,000 rubles for 1.5 l, but there are high-quality analogues on the market that meet the specification VW TL 774-G and are cheaper. We tested and selected the 5 best options:
| Brand and article | Type | Volume (l) | Price (rubles) | Features |
|---|---|---|---|---|
Motul Inugel Optimal (106377) |
G13 (yellow) | 1.5 (concentrate) | 1 200 | Contains glycerin, compatible with G12++ |
Liqui Moly KFS 2001 Plus (3806) |
G13 (orange) | 1.5 (ready) | 1 100 | Suitable for diesel engines with particulate filter |
| Febi 32600 | G13 (purple) | 1.5 (concentrate) | 900 | Low price but short service life (3 years) |
| Ravenol J1A2001 | G13 (blue) | 5 (ready) | 3 500 | Improved cavitation protection for turbo engines |
CoolStream Premium (CS010-005) |
G13 (yellow) | 5 (concentrate) | 2 200 | Approved VW Group, suitable for Kodiaq RS |
When choosing an analogue, pay attention to compliance with standard VW TL 774-G, and not by color. For example, Febi 32600 cheaper than the original, but its service life is lower - when used in difficult conditions (frequent traffic jams, towing a trailer) it is better to choose Motul or Liqui Moly.
For engines 2.0 TDI (especially with a diesel particulate filter) it is critical to use low silicate antifreeze. Optimal choice - Liqui Moly KFS 2001 Plus or Ravenol J1A2001.
Common mistakes when replacing antifreeze and how to avoid them
Even experienced car owners make mistakes that reduce the life of the cooling system. Here are the most common:
- 🚫 Mixing incompatible antifreezes. For example, G12++ and G11 form a gel-like residue that clogs the radiator. Always check the label!
- 🚫 Using tap water to dilute the concentrate. Salts and impurities cause corrosion. Only distilled water!
- 🚫 Incorrect bleeding of the system. Air pockets lead to local overheating. After replacing antifreeze, be sure to compress the radiator hoses while the engine is running.
- 🚫 Ignoring leaks. If the antifreeze level drops more than once every 2 months, check the tightness of the system (frequent leaks are on Kodiaq: thermostat pipe and pump).
Another typical problem is antifreeze overflow. In the expansion tank Kodiaq there are marks MIN and MAX, but when heated the liquid expands. If you fill it to capacity, at operating temperature the excess will splash out through the valve of the reservoir cap, which will lead to a loss of antifreeze and pressure in the system.
FAQ: Answers to popular questions about antifreeze for ŠKODA Kodiaq
Is it possible to mix G12++ and G13?
Yes, but only if both antifreezes meet the standard VW TL 774-G. G13 - this is an improved version G12++ with added glycerin, so they are compatible. However, mixing reduces the life of the fluid - after this, a complete replacement is recommended after 3 years.
What antifreeze is included in the new Kodiaq from the factory?
Since 2019, the conveyor has been using VW G13 (yellow or orange). Cars from 2017–2018 could have G12++ (purple). You can check the type by looking at the sticker on the expansion tank or in the service book.
What to do if antifreeze gets into the oil?
This is a critical malfunction that requires immediate engine shutdown. Signs: emulsion on the dipstick, white smoke from the exhaust pipe. Reasons: broken cylinder head gasket or crack in the block. The car cannot be operated in this condition - repairs are required.
How often should I check the antifreeze level?
At least once a month, and also before long trips. On Kodiaq The level is checked on a cold engine - it should be between MIN and MAX. If antifreeze is lost more than once every 3 months, leak diagnostics are necessary.
Can I use antifreeze from other brands (such as Toyota or Hyundai)?
No. Antifreezes from Asian manufacturers (for example, Toyota Long Life Coolant) have a different additive package and do not meet the standard VW TL 774-G. Their use will cause corrosion of aluminum parts and void the warranty.
