Volkswagen Golf Mk7 Owners Manual: Introduction

Never work on the Volkswagen Golf Mk7 engine coolant system without knowing the requisite procedures — this introduction sets that safety boundary directly before the warning display, specification and level-checking pages that follow, since the system runs under pressure when hot.

This chapter contains information on the following subjects:

 → Warning lamp and coolant temperature display  

 → Coolant specification  

 → Checking the coolant level and refilling coolant  

Never carry out any work on the engine coolant system if you are not familiar with the requisite procedures, or if you do not have access to the correct tools, operating equipment and fluids  . The work should be carried out by a qualified workshop if you are uncertain. Volkswagen recommends using a Volkswagen dealership for this purpose.

Serious injuries can be caused if work is carried out incorrectly.

Additional information and warnings:

  • Towing a trailer
  • Preparation for working in the engine compartment
  • Accessories, modifications, repairs and renewal of parts

WARNING

Engine coolant is toxic.
  • Engine coolant should only be kept in sealed original containers in a safe place.
  • Never store engine coolant in empty food containers, bottles or any other non-original containers as people finding these containers may then drink the engine coolant.
  • The engine coolant must be stored out of the reach of children.
  • Please note that the amount of correct coolant additive used must be sufficient for the lowest ambient temperature that you expect the vehicle to be exposed to.
  • Coolant can freeze at extremely cold outside temperatures, causing the vehicle to break down. Vehicle occupants with inadequate winter clothing could then freeze to death as the heating will also no longer function.

Coolant and coolant additives can pollute the environment. Spilt operating fluids must be collected and disposed of properly and with respect for the environment.

    Questions & answers

    Introduction — Volkswagen Golf Mk7

    Why is correct coolant important for the Golf Mk7?
    It prevents freezing in winter, raises the boiling point in summer, and contains corrosion inhibitors that protect the engine and radiator. Incorrect coolant can cause overheating and internal corrosion.
    Can I mix different coolant types in the Golf Mk7?
    Only use G 13 or a VW-approved equivalent. Mixing incompatible coolants can form sludge that blocks the radiator and heater matrix.
    Does the Golf Mk7 coolant need changing?
    Yes. It degrades over time. Volkswagen specifies a replacement interval in the service schedule — typically every few years.
