Another Valeo Question

[Magnum]

Hello There,
Cleaning the engine bay of my 06.12.2004 C270cdi avantgarde saloon with auto box today when I took off the nice plastic covers over the engine I saw what appeared to be old water staining marks and surface rust particularly around what I take to be the water pump area at the front top of the engine.also surface rust on the first three injectors, some parts had what appears to be light blue paint lines (only small) on them these apear to be newer looking parts.
Also on closer inspection I saw the word VALEO on top of the radiator surround,(one of three radiators) please tell me I havent bought a Duck egg.
I didnt think Valeo radiators were put in 2004 vehicles.

Your car is much to late to have a problem.
Even if it has a Valeo rad the crimping was changed, modified rads have a white spot on the oil cooler, but I do not no if this is the original ones fitted
