Little sisters 1994 pontiac firebird v6 3.4l at 120k miles.
Brown sludge buildup in her radiator, I replaced her thermostat and filled/bled a completely empty radiator and reservoir 3 months and 12k miles ago. Almost no smoke coming from the tailpipe and im not getting any cylinder misfires or codes.
