Engine coolant

[hmmmm]

Noticed my coolant is nearing the 'low' mark and going to top it up. Got some coolant from Halfords i've had for years. Can i just use that or does it have to be the same make as Skoda use? If so then what one does Skoda use?

The manual is very specific about using the right specification coolant, needs to be G12 spec, also known as TL774D iirc.

You had G12 then G12+ then G12++ and now G13. You can mix them OK though.

Extract from the Octavia Owner's manual:

Cooling system

Coolant

The job of the coolant is to cool the engine.

The cooling system does not require any maintenance under normal operating condi- tions. The coolant consists of water with a concentration of coolant additive of 40 %. This mixture not only provides antifreeze protection down to -25°C but also protects the cooling and heating system from corrosion. It also prevents the formation of scale and significantly increases the boiling point of the coolant.

You must therefore not reduce the concentration of antifreeze agent in the coolant by adding water, also not during the summer months or in countries with a warm climate. The concentration of coolant additive in the coolant must be at least 40%.

You can increase the amount of antifreeze in the coolant if a higher concentration of antifreeze is necessary for climatic reasons but only up to 60% (antifreeze protection down to approx. -40°C). The antifreeze protection tails off above that concentration.

Vehicles exported to countries with a cold climate (e.g. Sweden, Norway, Finland) are already factory-filled with a coolant which offers antifreeze protection down to about -35°C. In these countries the concentration of coolant additive should be at least 50%.

Coolant

The cooling system is factory-filled with coolant (purple in colour), which complies with the specification TL-VW 774 G.

We recommend that you use the same coolant additive - G13 (purple in colour) - for topping up the system.
