Pt cruser 2004 what could it be?

Need alittle brain power my way on
what this could be I purchased a 04pt
cruiser (‍♀️) had a slight wrattle
coming from engine was told it was a
bracket that was loose/broken from
exaust so I purchased it might I just
add I had my ex look at her too and
he said it was a easy fix lol (ex for a
reason) so I was driving her fine
down the road the wrattle started
getting louder then I heard a clunk
then scraping sound so I quickly
turned into Bunnings and parked her
got out and went to look when I
noticed she was peeing coolant all
over the ground! Tryed to put more
water in her but she leaks everywhere
like my grandma when laughing! She
didn't over heat there is no water in
oil etc yet she turns over but does not
start now??
