newbie with radiator prob

Wondering if anyone has had this problem before? After getting my car back from getting a new timing belt, noticed a fine green spray under my hood, on the engine, intake, battery etc. Fine green mist now puddles of green on top of the radiator fans and spots everywhere. I don't know what happened! Thanx for any help!!

maybe leaky hoses ,cap etc.

I thought it was just the cap at first, but now it seems to be from all the way across the radiator. I'm gonna double check everything, maybe I missed something. Thanks for the advice!

cracked radiator? plastic ones are easy to crack

Hey thanks for all the advice. Turns out there was a small leak in the seal at the top of the radiator. But I get a dope new one so I guess its ok.
