2008 HONDA CIVIC SI Engine Problems

COOLANT LEAK FROM THE RADIATOR. NEW HEAD GASKETS, NEW SEALS. MYSTERY COOLANT LEAK, COOLANT PUSHES FROM THE RADIATOR TO THE OVERFLOW, LEAVING RADIATOR LOW COOLANT. NEW SEALS AND NEW WATER PUMP, NO DRIPS OR INDICATION OF LEAKING

MY 2008 HONDA CIVIC SI HAS BEEN LEAKING COOLANT FOR THE PAST COUPLE WEEKS. IT IS CURRENTLY AT AROUND 115,000 MILES. I NOTICED ALL OF THE EXTENDED WARRANTY INFORMATION ABOUT THE 06-09 HONDA CIVICS AND CONTACTED BOTH THE DEALERSHIP AND CORPORATE MYSELF. THEY TOLD ME THAT BECAUSE MY MODEL WAS NOT THE BASE MODELS BUT THE SI THAT IT WAS A DIFFERENT ENGINE AND THAT THEY COULD NOT HELP ME. HOWEVER I AM GOING TO GET THE CAR BACK FROM MY MECHANIC TODAY WHO ESTIMATED THE REPAIRS WOULD BE $4500 TO COMPLETELY REPLACE THE ENGINE. HE ALSO BROUGHT UP THIS EXTENDED WARRANTY ISSUE AND SUGGESTED I CONTACT HONDA AGAIN BECAUSE THE PRESSURE FRACTURES ARE IN THE EXACT SAME PLACE AS THEY ARE ON THE BASE MODEL 06-09 ENGINE BLOCKS. FROM MY KNOWLEDGE AND THE MECHANICS THE ENGINES MAY NOT BE THE SAME BUT THE BLOCK IS MADE OF THE SAME...
