Green liquid on engine block
 

I have a small amount of bright ish green liquid on the block of my hyundai trajet, at first I thought it was coolant but..

my coolant is pink (halfords advanced, full flush 1-2k miles ago)
screen wash is pink

what could it be please?,

From a quick look, I cant see any leaks, but I have lost a v small amount of coolant (1/2 to 1cm in the coolant bottle from the max line) over the last few k miles

thanks

Dead alien. :wonder:

Iirc some Korean and Japanese cars use weird coloured rust proofing spray on the underside of the drivetrain components (subframe, gearbox, engine block etc. )

The latest Uk Sti is the same.

Could be oil that has leaked from the aircon system, it carries a fluorescent dye so leaks can be traced easily.

Yeah I forgot about the UV dye. It glows if ultraviolet light is shone at it, if it ever gets near the cooling fan it goes absolutely everywhere.

Yeah I use it in work, disaster if it gets on skin and clothes! And yes, UV would be correct lol. I was just awake when I typed the first post!

good call on the air con fluid, Ill check it out some more

thank you
