Re: IML: 1967 Thermostat

["mike and cindy" <mbecker30@xxxxxxxxxxx>]

my 67 vert did that , I flushed the system twice and had the radiator redone 
, it still tended to get hot, not as bad, but it would still get hot. ended 
up removing the engine, pulled out the freeze plugs,used coat hangers and 
such with the waterhose. turns out the lower 1/2 of the block was full of 
rust/sand? choking off the water flow . did a cleaning/ inspection and 
rebuild of the engine and trans, never got past 1/3 on the temp gauge after 
that.
