Engine coolant

Introduction

390

Only perform work on the engine cooling system if you are familiar with the necessary activities and the general safety

precautions, and if the correct operating equipment, ﬂuids and suitable tools are available. Work performed incorrectly can

result in serious injuries ⇒

. Have all work performed by suitably qualiﬁed professionals if necessary. Volkswagen

recommends contacting an authorized Volkswagen dealer or authorized Volkswagen Service Facility.

Information about warning and indicator lights can be found in the troubleshooting section at the end of the chapter

⇒ Troubleshooting.

WARNING

Engine coolant is poisonous. Contact with coolant, especially swallowing coolant, may result in serious or fatal injuries.

If you swallow coolant, seek urgent medical help.

If you have health problems after working with coolant, seek medical help.

Always store engine coolant out of the reach of children and only within the sealed original container.

Never use empty food cans, bottles, or other containers to store engine coolant, because someone could drink the

engine coolant by mistake.

Avoid regular contact with coolant to prevent damage to your skin.

Protect your skin, face, and particularly your eyes when working with coolant.

Do not eat, drink, or smoke when working with coolant.

Wash your skin with soap and water after working with coolant.

WARNING

In extremely low temperatures, the coolant can freeze and the vehicle could break down. This can cause the heating to

stop working in the vehicle. Vehicle occupants could die of exposure if they do not have sufﬁcient warm clothing.

Make sure the coolant additive is always adjusted according to the ambient temperature.

Only use coolant additive approved by the manufacturer.

Coolant and coolant additives can pollute the environment. Catch any leaking operating ﬂuids and dispose of them

correctly according to environmental regulations.

Engine coolant speciﬁcations

Please read the introductory information and heed the Warnings and Notice ⇒

Safety precautions for working in the

engine compartment.

The cooling system is ﬁlled at the factory with a mixture of specially prepared water and at least 40% coolant additive G12evo

(TL 744-L).

The proportion of coolant additive must always be at least 40% to protect the engine cooling system. If greater freeze

protection is needed due to the climate, the proportion of coolant additive can be increased. However, the proportion of

coolant additive must not exceed 55%, because otherwise the freeze protection will be reduced and the cooling effect will be

decreased.

The engine coolant additive can be recognized by its violet color. The mixture of water and coolant additive provides freeze

protection down to approx. -25 °C (approx. -13 °F), protects the light-alloy parts in the cooling system against corrosion,

prevents calcium deposits and signiﬁcantly increases the boiling point of the coolant.

If the engine coolant is being topped up, a blend of distilled water and at least 40% of the G12evo engine coolant additive mus

391

be used to ensure optimum corrosion protection ⇒

.

NOTICE

The coloring of the engine coolant results from the mixture of the purple coolant additive and distilled water. If the ﬂuid in

the coolant expansion tank is not purple, but for example brown, the engine coolant has been mixed with another non-

suitable coolant. This may result in serious malfunctions or damage to the drive and cooling system.

Only use coolant additive approved by the manufacturer.

If the coolant turns brown, have it changed immediately by an authorized Volkswagen dealer or authorized

Volkswagen Service Facility. Volkswagen recommends contacting an authorized Volkswagen dealer or authorized

Volkswagen Service Facility.

Never mix original Volkswagen coolant additives with coolant additives that are not approved by Volkswagen when

topping up.

Engine coolant and coolant additives can harm the environment.

1. Catch any leaking operating ﬂuids and dispose of them correctly according to environmental regulations.

WARNING

Escaping hot steam or hot coolant and hot components may cause serious burns.

Never open the engine hood if you can see or hear steam or coolant escaping from the engine compartment.

Always wait until you can no longer see or hear steam or engine coolant escaping from the engine compartment.

WARNING

The engine cooling system is under pressure when the engine is hot. If the cover is opened carelessly, coolant may spray

out and cause serious burns or fatal injuries.

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

Always protect your face, hands and arms from hot coolant or steam with a large, thick cloth if you have to open the

cover of the coolant tank.

Slowly and very carefully turn the cap on the coolant expansion tank counterclockwise while pressing down lightly

on the cap.

Checking the coolant level

Fig. 172 In the engine compartment: markings on the engine coolant expansion tank.

When new vehicles are delivered or after repairs to the cooling system, the coolant level may be above the marked area. This

is normal. The coolant does not need to be extracted.

The coolant level cannot be checked exactly for every model, because the view of the ﬂuid level in the coolant expansion tank

may be obstructed. If you cannot read off the engine coolant level accurately, contact a suitably qualiﬁed professional.

Volkswagen recommends contacting an authorized Volkswagen dealer or authorized Volkswagen Service Facility.

393

1. When the engine is cold, check the coolant level using the markings on the side of the engine coolant expansion tank

ﬁg. 172. The coolant level must be between the markings.

2. If the ﬂuid level in the coolant expansion tank is below the minimum mark (“min”), have coolant added. When the engine i

warm, the engine coolant level may be slightly above the upper marking.

3. If no coolant is visible in the coolant expansion tank, do not add coolant ⇒

.

Filling the coolant

1. Carefully unscrew the cap ⇒

.

2. Only add new coolant that conforms to the Volkswagen speciﬁcation ⇒ Engine coolant speciﬁcations.

If there is no engine coolant available that conforms to the required speciﬁcation, initially only top up with distilled water.

Then have the correct mixture ratio using the speciﬁed coolant additive restored as soon as possible by an authorized

Volkswagen dealer or authorized Volkswagen Service Facility. Volkswagen recommends contacting an authorized

Volkswagen dealer or authorized Volkswagen Service Facility ⇒

.

3. Top up the engine coolant to the upper ﬁll level marker. After topping up the engine coolant, the coolant level must be

between the markings on the coolant expansion tank ﬁg. 172.

4. Install the cap securely.

5. Check the coolant level after one day. If the ﬁll level of the coolant reservoir again drops below the “min” minimum

marking, contact an authorized Volkswagen dealer or authorized Volkswagen Service Facility and have the cooling

system checked. Volkswagen recommends contacting an authorized Volkswagen dealer or authorized Volkswagen

Service Facility.

NOTICE

Coolant expands when it heats up. If coolant is topped up above the marked level, excess coolant may leak out and

cause damage to the vehicle.

Do not reﬁll the system with engine coolant above the upper edge of the marked area of the engine coolant tank.

NOTICE

If there is no more engine coolant in the coolant expansion tank, air can get into the cooling system. This could result in

damage to the engine.

Do not continue driving.

Do not top up the coolant.

See an authorized Volkswagen dealer or authorized Volkswagen Service Facility for assistance.

NOTICE

The chemical components contained in water that is not distilled can cause considerable corrosion damage in the engine.

This can cause engine malfunctions.

Only use distilled water for reﬁlling the system!

If you have added water that is not distilled, have the ﬂuid in the cooling system changed completely by an

authorized Volkswagen dealer or authorized Volkswagen Service Facility. Volkswagen recommends contacting an

authorized Volkswagen dealer or authorized Volkswagen Service Facility.

Brake ﬂuid

Introduction

Brake ﬂuid absorbs moisture from the air over the course of time. Too much water in the brake ﬂuid causes damage to the

brake system. Water lowers the boiling point of the brake ﬂuid. If the water content in the brake ﬂuid is too high, vapor lock ma

form in the brake system during heavy braking and full braking. Vapor lock reduces the braking efﬁciency, increases the

braking distance considerably, and can lead to a total failure of the brake system. Your own safety and the safety of others on

the road depends on your brake system functioning correctly at all times.

WARNING

Brake ﬂuid is poisonous. Contact with brake ﬂuid – in particular, if brake ﬂuid is swallowed – may result in serious injury or

death.

If you swallow brake ﬂuid, seek urgent medical help.

If you have health problems after working with brake ﬂuid, seek medical help.

Always store brake ﬂuid out of the reach of children and only within the sealed original container.

Never use empty food cans, bottles, or other containers to store brake ﬂuid, because someone could drink the

brake ﬂuid by mistake.

Avoid regular contact with brake ﬂuid to prevent damage to your skin.

Protect your skin, face, and particularly your eyes when working with brake ﬂuid.

Do not eat, drink, or smoke when working with brake ﬂuid.

Wash your skin with soap and water after working with brake ﬂuid.
