Get Checking and filling -> Checking and filling engine coolant Guide for Volkswagen Atlas SUV First Generation (2018-2023)

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.

Serious malfunctions or damage to the engine and cooling system could occur!

Immediately have the engine coolant changed by suitably qualiﬁed professionals. Volkswagen recommends contacting an authorized Volkswagen dealer

or authorized Volkswagen Service Facility.

Never mix Genuine Volkswagen coolant additives with coolants that are not approved by Volkswagen when topping up.

Engine coolant and coolant additives can harm the environment. Catch any leaking operating ﬂuids and dispose of them correctly according to environmental

regulations.

Checking and ﬁlling engine coolant

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

Safety precautions for working in the engine compartment .

Preparations

1. Parking the vehicle on a level, secure surface.

2. Allow the engine to cool ⇒

3. Open the hood.

The coolant expansion tank is identiﬁed with the

red symbol on the cap ﬁg. 192.

Fig. 192 In the engine compartment: cap on the engine coolant expansion tank.

WARNING

Hot steam and hot engine coolant can cause serious burns.

Never open the engine hood if you can see or hear steam or coolant escaping from the engine compartment. Wait until you can no longer see or hear

steam or coolant escaping. Hot components can cause burns if touched.

WARNING

The engine cooling system is under pressure when the engine is hot. Never open the cap on the coolant expansion tank when the engine is hot. Engine coolant

could spray out and cause serious burns or other injuries.

Slowly and very carefully turn the cap counterclockwise while pressing down lightly on the cap.

Always protect your face, hands, and arms from hot coolant or steam by placing a large, thick cloth on the coolant expansion tank cap.

Checking the coolant level

314

Fig. 193 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 rea

off the engine coolant level accurately, contact a suitably qualiﬁed professional. Volkswagen recommends contacting an authorized Volkswagen dealer or

authorized Volkswagen Service Facility.

1. When the engine is cold, check the coolant level using the markings on the side of the engine coolant expansion tank ﬁg. 193.

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 is 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. 193.

4. Install the cap securely.

5. Check the coolant level after one day. If the level of the engine coolant tank drops below the “min” minimum marking again, 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.

6. If there is no engine coolant available that conforms to the speciﬁcation, do not use any other engine coolant additive in an emergency

⇒

NOTICE

If there is too much engine coolant, it will escape from the cooling system under high pressure when the coolant warms up, which can result in damage.

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

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.

Stop driving and do not top up with engine 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 water that is not distilled is added, have the ﬂuid in the cooling system changed immediately by a qualiﬁed workshop. Volkswagen recommends

contacting an authorized Volkswagen dealer or authorized Volkswagen Service Facility.

NOTICE

The use of incorrect ﬂuids can cause serious malfunctions and damage to the engine.

When topping up ﬂuids, make sure the correct ﬂuids are added to the correct reservoirs.

Troubleshooting

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

Safety precautions for working in the engine compartment .

Engine coolant

The red warning light blinks. The coolant temperature is too high or the coolant level is too low.

Do not continue driving! Engine damage could result.

1. Stop the vehicle as soon as it is safe to do so ⇒ Parking.

2. Stop the engine.

3. Allow the engine to cool.

4. Check the engine coolant level on the Coolant expansion tank ⇒ Checking and ﬁlling engine coolant .

5. If the warning light does not turn off, do not continue driving or let the engine run, even if the engine coolant is at the correct level.

6. Contact an authorized Volkswagen dealer or authorized Volkswagen Service Facility for assistance.

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 may 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.

To reduce the risk of poisoning, never store brake ﬂuid in beverage containers or other containers. A person could mistakenly drink from the container,

even if the container is marked.

Always store brake ﬂuid in the sealed original container and keep it out of the reach of children.

NOTICE

Spilled or leaking brake ﬂuid damages vehicle paint and tires.

Immediately wipe up any spilled or leaking brake ﬂuid that comes into contact with vehicle components.

Brake ﬂuid can pollute the environment. Collect spilled brake ﬂuid and dispose of it correctly.

Brake ﬂuid speciﬁcations

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

Safety precautions for working in the engine compartment .

Volkswagen has developed a special brake ﬂuid that is optimized for the vehicle's brake system. For optimum performance of the brake system, Volkswagen

recommends only using brake ﬂuid that complies with the “VW standard 501 14”.

Before using brake ﬂuid, check that the brake ﬂuid speciﬁcation on the bottle matches the vehicle requirements.

Brake ﬂuid that complies with the VW standard 501 14 can be obtained from an authorized Volkswagen dealer or authorized Volkswagen Service Facility.

If brake ﬂuid that meets this speciﬁcation is not available and another high-quality brake ﬂuid must therefore be used, brake ﬂuid that complies with the speciﬁcation
