Get Coolant -> Checking coolant level and refilling coolant Guide for Volkswagen Polo SUV Seventh Generation (2021-2025)

Preparations

1. Park the vehicle safely on a horizontal and firm surface (→ Parking).

2. Allow the engine to cool down →

3. Open the bonnet.

The coolant expansion tank can be recognised by the red symbol on the cap → Fig. 1.

In the bonnet space: coolant expansion tank cap

WARNING

Escaping hot steam or hot coolant and hot vehicle parts can cause severe burns.

● Never open the bonnet if steam or coolant is visibly or audibly emerging from the bonnet space.

● Always wait until you can no longer see or hear steam or coolant coming from the bonnet space.

WARNING

The cooling system is under pressure when the engine is hot. If the cap is opened carelessly, coolant can spray out and cause severe

burns or fatal injuries.

● Never open the cap of the coolant expansion tank when the engine is hot.

● If you have to open the cap of the coolant expansion tank, always protect your face, hands and arms from hot coolant or steam

with a large, thick cloth.

● Turn the cap of the coolant expansion tank slowly and very carefully anticlockwise while exerting slight downwards pressure on the

cap.

Checking coolant level

In the bonnet space: markings on the coolant expansion tank

(illustration).

The coolant may be above the marked area upon delivery of new vehicles or after repairs to the cooling system. This is normal. The

coolant does not have to be sucked off.

The coolant level cannot be checked accurately in all models as visibility of the fluid level in the coolant expansion tank may be

obstructed. If the coolant level cannot be read exactly, contact a suitably qualified workshop. Volkswagen recommends using an

authorised Volkswagen repairer.

1. Check the coolant level at the side markings of the coolant expansion tank when the coolant is cold → Fig. 2. The coolant level

must be between the marks.

2. Have coolant added if the fluid level in the coolant expansion tank is below the minimum marking “min”. If the coolant is warm,

the coolant level may be slightly above the upper mark.

3. Do not add coolant if there is no longer any coolant visible in the coolant expansion tank →

Topping up coolant

1. Unscrew the lid carefully →

2. Add only new coolant in accordance with the Volkswagen specification up to the upper level marking. (→ Coolant). After adding

the coolant, the coolant level must be between the markings on the coolant expansion tank → Fig. 2.

3. Close the cap tightly.

4. Check the coolant level after one day. If the level of the coolant expansion tank drops below the “min” marking again, visit a

suitably qualified workshop and have the cooling system checked. Volkswagen recommends using an authorised Volkswagen

repairer.

If in an emergency you do not have access to coolant in the required specification, add only distilled water initially. Then have the

correct mixture ratio with the coolant additive restored by a suitably qualified workshop as soon as possible. Volkswagen recommends

using an authorised Volkswagen repairer →

NOTICE

Coolant expands when it is heated. If coolant is added so that the level is above the marked area, excess coolant could escape and

damage the vehicle.

● Do not fill coolant above the top edge of the marked area on the coolant expansion tank.

NOTICE

Air may have entered the cooling system if there is no longer any coolant in the coolant expansion tank. This could cause damage to

the engine.

● Do not drive on.

● Do not add coolant.

● Seek expert assistance.

NOTICE

Use of water other than distilled water can cause considerable corrosion damage in the engine due to the chemical substances

contained in the water. This can lead to failure of the engine.

● Refill only with distilled water!

● If you have not used distilled water for refilling, the fluid in the cooling system should be completely replaced immediately by a

suitably qualified workshop. Volkswagen recommends using an authorised Volkswagen repairer.

NOTICE

Use of the wrong service fluids can cause serious malfunctions and damage the engine.

● When adding or replacing service fluids, ensure that you pour the correct service fluids into the corresponding openings.

The coolant temperature is too high or the coolant level is too low

The warning lamp lights up red. A message is shown on the instrument cluster display.

Do not drive on! The engine could otherwise be damaged.

The coolant temperature is too high or the coolant level is too low.

1. Stop the vehicle as soon as possible and when safe to do so (→ Parking).

2. Switch off the engine.

3. Allow the engine to cool down.

4. Check the coolant level in the coolant expansion tank (→ Coolant).

5. Do not drive on or leave the engine running if the warning lamp does not go out even though the coolant level is correct.

6. Seek expert assistance.
