Coolant Type

[GT RCZ]

Hi Guys
I have sent my THP200 in for its annual service today + the heater is not getting hot.
They suspect that the heater matrix is blocked due to the wrong type of antifreeze.
The car I purchased new & has only been serviced by the selling dealer and I have only topped up with a little water.
What colour is your coolant?

Blue

Does adding water to the coolant weaken the mixture.
Is the coolant a mix to prevent internal corrosion of the cooling system and by adding water introducing a possible source of corrosion.

The coolant should be blue.

I've bought the original one for Peugeot / Citroen.

The instructions say to apply directly, without mixing water.

I do believe, however, if you only add a small quantity of water, it will make no big difference. But just a little bit!

But I do advice you, from my experience on more than one RCZ: topping the coolant level will be a regular maintenance, so just buy the official coolant, or adding water will start to be a regular thing...
