Reference my 3.3L Korean built Sonata. Built Nov 1 2006. I've been reading on another forum about aluminium particle contamination in the coolant. Also read here,
Would anyone know if,
1) The particles cause any mechanical damage (water pump?)? 2) The particles clog-up the radiator? 3) A system back-flush would clean all the particles out? 4) Then refill with clean coolant would be an end to the matter?cheers, nn
