Signs of a malfunctioning heater radiator

Before you start replacing, make sure that the problem is in the heater radiator. Here are the main symptoms:

• 💧 Antifreeze is leaving. without visible stains under the car (liquid evaporates in the cabin through the stove).
• 🌬️ The windows are fogging up from the inside, even in dry weather, is a sign of coolant entering the ducts.
• 🔥 The stove blows cold air with a warmed-up engine (clogging or air traffic jam).
• 🚗 Sweetish smell In the cabin - tosol or antifreeze seeps through the radiator.

If any of these signs appear, check the level of antifreeze in the expansion tank. Nana Octavia Tour with engines 1.6 MPI, 1.8 TSI or 2.0 TDI The heater is located behind the center console, and its replacement requires partial disassembly of the cabin. Don’t confuse this with a failure. stove tap (relevant for older models) or thermostat - their diagnosis and replacement are carried out differently.

⚠️ Attention: On climate-controlled vehicles (Climatronic) before replacing the radiator, it is necessary relieve pressure in the air conditioning system. If this is not done, when the tubes are disconnected, the refrigerant will break out under pressure and may damage the eyes or skin. Use protective glasses and gloves!

What tools and spare parts will be needed

To replace the heater radiator with Škoda Octavia Tour you will need:

Category	Name	Notes
Tools	Socket set (8–13 mm)	Be sure to have an extension and cardan for hard-to-reach bolts
Tools	Flathead and Phillips screwdrivers	To remove plastic clips and clamps
Tools	Plastic spatulas for removing trim	So as not to damage the latches of the instrument panel
Consumables	Heater radiator (art. no. 1K1 819 013 AN or 1K1 819 013 H)	For A5/A7, the original or analogues are suitable. Behr, Nissens, Mahle
Consumables	Clowns (4 pcs., diameter 16-22 mm)	Better to take springs - they are more reliable than regular ones

Additionally prepare:

• 🧴 Cooling system sealant (for example, Liqui Moly Kuhler-Dichter).
• 🚿 Distilled water (5-10 liters) for washing the system.
• 🧤 Rubber gloves — antifreeze is toxic!
• 📦 Refrigerant discharge tank (Not less than 6 litres in volume).

Preparing the car: draining the antifreeze and removing the panel

Before starting work necessarily Pour the antifreeze. Nana Octavia Tour the drain plug is located at the bottom of the engine cooler (right in the course of movement). Algorithm:

1. Set the machine on a flat surface and tuck the front (or use a pit).
2. Remove the engine protection (if equipped).
3. Put the container under the drain plug and unscrew it counterclockwise.
4. Unscrew the lid of the expansion tank - this will accelerate the drain.
5. After draining, twist the plug back and rinse the system with distilled water (pour, warm up the engine, drain).

Now proceed to the disassembly of the salon. Nana Octavia Tour The heater is hidden behind the center console, so you will have to remove:

• 🔧 Glove box (glove compartment) Unscrew 4 bolts from the bottom and move it to the side.
• 📻 Center console - remove the lining around the gearbox lever, then unscrew the bolts under the cupholders.
• 🚗 Instrument panel - Unplug all connectors (remember or photograph their location!).

⚠️ Attention: On models with climate control Before removing the panel, you need to turn off the battery! Otherwise, the control unit may fail due to a voltage surge when disconnecting the connectors.

Removing the old stove radiator: step-by-step instructions

After removing the panel, you will get access to the oven body. The radiator is located at the bottom and is attached to it with two bolts. Here's how to take it off:

1. Disconnect pipes from the radiator, loosening the clamps. Be prepared for the fact that the remainder of antifreeze will flow out of them - substitute a cloth.
2. Unscrew two radiator mount bolts (usually under the head by 10 mm).
3. Carefully remove the radiator from the oven body, tilting it towards the passenger. Don't use force If it doesn’t come out, check if you forgot to disconnect any connector or tube.

Check the old radiator: if it shows signs of corrosion or mechanical damage, the cause of the leak is obvious. If it is not warmed outwardly, the problem could be in honeycomb - in this case, the new radiator should be washed with a special liquid before installation (for example, Hi-Gear Radiator Flush).

What to do if the radiator mounting bolts are soured?

If the bolts don’t unscrew, use penetrating lubricant (such as WD-40) and let it last for 10-15 minutes. If this does not help, try to heat the bolt with a building hair dryer - the metal will expand, and the rust will loosen the grip. In extreme cases, you will have to cut the bolts with a Bulgarian, but this is risky - you can damage the body of the stove.

Installation of a new radiator and assembly

Before installing a new radiator, check it. seal-integrity on the pipes. If they are hardened or torn, replace them. It is also recommended to apply a thin layer of sealant to the connection of the pipes with the radiator - this will prevent leakage in the future.

Installation algorithm:

1. Insert the radiator in the body of the stove, combining the holes under the bolts.
2. Twisting the mounting bolts (do not pull - you can tear the thread!).
3. Connect the pipes and tighten the clamps. Spring clamps are better to tighten with pliers until a characteristic click.
4. Make sure the radiator sits tight and doesn't hang around.

After installing the radiator, proceed to reassemble the interior in reverse order. Pay special attention to:

• 🔌 Connecting connectors dashboards – an incorrect connection can disable the control unit.
• 🔧 Bolt tightening The center console - if they are not enough, there will be creaks.
• 🚗 Adjustment of the oven crane cable (on models without climate control) – if it is not adjusted correctly, the stove will only work in one mode.

Refilling the cooling system and checking

After assembly, fill in a new antifreeze (recommended for Škoda Octavia Tour — G12++ or G13). The volume of the system is about 6 liters, but after replacing the radiator of the stove, it may be necessary to add. The gas station algorithm:

1. Fill the expansion tank with antifreeze to the mark MAX.
2. Start the engine and warm it up to operating temperature (sensor arrow should reach the middle).
3. Distill several times to 3000 revolutions - this will help to expel the air from the system.
4. Add antifreeze to the level (it will go away when it warms up).
5. Check the operation of the stove in all modes.

If after refueling the stove is not warm enough, most likely, air remained in the system. To pit him against:

• 🔧 Unscrew vent on the pipe going to the radiator of the stove (it is on the passenger side).
• 🚗 Wait until the antifreeze goes out of the hole without bubbles, and twist the cork.

Common mistakes and how to avoid them

Even experienced car owners make mistakes when replacing a heater radiator. Here are the most common:

Error	Consequences	How to avoid
Not completely drained the antifreeze.	Pollution of the cabin, the risk of liquid getting on electronics	Rinse the system with distilled water until clear drain
Damaged the air ducts during disassembly	Screams, incorrect air distribution	Use plastic spatulas and do not apply force.
Don't blow the air out of the system.	The stove does not heat up, the engine overheats	Warm up the engine and blow air through the plug on the pipe
Used poor-quality clamps	Antifreeze leakage after 1-2 months	Take the spring-clamps from Norma or Würth

Another typical problem is erroneous assembly, because of which the lamps on the device start to burn or the backlight fails. To avoid that, Take a photo of all the connectors before disconnecting. And label them with scotch.
