coolant color

[poppies]

dear members,

my car is one and half year old. if i'm right, i remember being able to

see the coolant through its plastic shell as blue/green.

my car doesn't go out a lot; i was unable to drive for quite long and she stayed

in the garage; as i'm back and drive it again, i noticed that the coolant's colour

tend to look green/yellow through the plastic container.

i'm not strong enough to open the container for now :( and can't tell you

exactly what the colour is.

Anyway, I would be curious to know if the colour mutation is normal, from

this blue to a yellow/green. Knowing that in theory, the liquid doesn't have

to be changed, I find this disturbing. :help:

thank you to let me know what you've experienced

I am aware of the stupidity of this topic. Anyway, could someone would

be kind enough to tell me if the color varaition is normal?

Thank you.

Zach.

This is the original coolant from when I replace the tank on my 1997 Boxster last year.

This is what new coolant looks like.

Thank you for the photos Tool Pants. It's interesting to see the degradation of those colours.

I hope the coolant fluid keeps its function, I mean the whole chemistry of the fluid remains

intact; if I am correct, the coolant lifetime is supposed to be equal to the car's. Still, I wonder...

I was told by a European friend "lifetime" meant 100,000 km (60,000 to those of us in the USA). Has anyone else heard that?

The Porsche service manual says:

The engine cooling system is factory-filled with a coolant which does not need to be changed. The coolant should not be mixed with other coolants.

Only Original Porsche anti-freeze should be used when changing or topping up the coolant.

Hi Loren,

Thank you for your very accurate extract. I was on the verge to change the coolant... :notworthy:

Just a note, I would suggest using Mobil one's latest generation coolant, its chemistry is advcanced in both anti corrosion and thermal transfer properties. There are also other common sense advantages
