HI, at the bottom of my car right in front of the driver side, there is a pinkish liquid leaking and it's coming in small quantities and one drop at a time. I'm suspecting that maybe that liquid is radiator coolant, If not what do you think it could be? Maybe the valve seal for the radiator coolant reservoir is broken and needs to be replaced. Can you please advise me of what I should tell the mechanic to look for when I get it into a garage so he can get to it right away. Any help will gladly appreciated. Thanks so much for your time.
