Timing belt broke but there's more Ford Escort ZX2
So I was driving along and I've been having some
problems with the heating and it would go hot and
cold and then it would stay hot for a good hour on
one of my longer drives and then it would just go
freezing cold all the sudden so I'm thinking OK it's
a cable in the cooling system blowing and coolant
came out from underneath the car but I started the
car back up and it drove and it drove for another
10-15 miles before all the sudden a clacking tin like
sound started happening and it stalled out and I
was on the side of the road found on road dead
anyway I was told by a mechanic friend of mine
who also runs a tow truck company that it is the
timing belt that broke after he replace spark plugs
because I thought that might be it but of course I
was wrong and now it sits up at a shop waiting for
morning so that they can look at it my question is
why would any coolant come out of the vehicle if
the timing belt broke is that in something that
would normally happen or is it because my stupid
brother in law over filled the coolant in the actual
radiator please help me I am so fed up with this car
it has 117 k and everything works inside and out
except for the timing belt and the Heat no I thought
about it being the heater core but it doesn't make
sense so if anybody can explain this conundrum I
would really appreciate it I've already put a lot of
money into this car and I don't have the means to
continue doing so especially after this fix
supposed to be moving into an apartment this
weekend and I don't know if that's going to happen
but I am freaking out about this stupid situation
please help and I'll give you a free tattoo I swear
