the coolant in my 2006 2.0 tdci is an orangey/pink colour. Can i assume that with the colder mornings coming in that i have a strong enough concentration of anti freeze in there? Or should waste money and buy a tester?

cheers

There is probably someone about who will check it for you FOC, but [u]do[/u] get it checked, colour is a rough guide only. When I was a lad we used to test it by taste do not try this, it is poisonous and not a good guide.
I'm not sure about present recommendations for your car, but it is usually to have A/F changed every 2 years, has yours been changed? I believe this is more related to anti corrosion properties than anti freeze properties.
