Original factory marks ?

[pv-camaro]

hi,

I have a European 2001 3.8V6 Camaro with 36.000km (about 22.000miles), and i bought the car from the first owner (about 2,5 year ago).

My question, in the engine compartment are some marks, and letters written on it (see photo's), are these assembly marks ?
they are on the steering fluid reservoir, some hoses, and the airlid.
colors in white, green and red.

i doubt it bro. it's something i've seen more often from a junk/salvage yard part. nothing wrong with that, but it's just what i've experienced. it could be factory markings, but i don't have anything like that on any parts OEM on my car. could it be a V6 thing?

Mechanics usually do that after a parts inspection or service
