I recently bought a 2003 chevy v6 vortec
blazer. And when going to change the oil I
noticed I was leaking coolant. It didn't leak
to bad at first but by that time the next day
I had taken it over to my buddy's garage
where when we filled the radiator mad
overflow with coolant it drained in around
10 to 15 minuets. See now I had not only
my self but my father my mechanic buddy
and brother in law looking to find where the
leak was coming from. It seems to be
coming from under the motor block but still
can't find the leak. Anyone have similar
issues or know what it could be.?
Check the intake manifold gaskets. It may be leaking from there and running down. Use a pressure tester and pressurize the cooling system. You'll be able to at least hear the leak by the hissing sound where the leak is. HTH. -Jim
Oh and check the freeze plugs. One may be rusted through. HTH. -Jim
Did you find out what it was? I have same problem.
