2003 4 CYLINDER TOYOTA HIGHLANDER. COOLANT LEAK AND SUBSEQUENT NEED FOR A NEW REPLACEMENT ENGINE DUE TO THE DEFECT OF 3 REAR ENGINE SHORT BLOCK SCREWS/THREADS. HAD LESS THAN 85K MILES ON VEHICLE, WHEN FOUND A COOLANT LEAK UNDERNEATH ENGINE BLOCK OF VEHICLE IN GARAGE AFTER HAVING NO ISSUES PRIOR WITH ENGINE, RADIATOR OR ANY ASSOCIATED ACCESSORIES TO THE COOLANT SYSTEM/ENGINE SYSTEM OF VEHICLE. TOOK TO A TOYOTA DEALER PRIOR TO ANY OVERHEATING OR VEHICLE OPERATION FAILURES OR RADIATOR FAILURE. TOYOTA DEALER PULLED ENGINE MANIFOLD AND COVER OFF TO INVESTIGATE AND FOUND THAT WHEN THEY PULLED THE THREE SCREWS THAT CONNECT THE ENGINE COVER THAT COVER THE HEADS/CYLINDERS, THE THREADS ASSOCIATED WITH THE SCREWS CAME WITH THEM. THE ONLY FIX PER DEALERSHIP DETERMINED TO BE A BRAND NEW SHORT ENGINE BLOCK AND ACCESSORY REPLACEMENT FOR $6,470. DATE ON THIS IS AUGUST/2010. HAVE ALL PAST SERVICE HISTORY OIL CHANGES/TRANSMISSION CHANGES, RADIATOR...

MY 2003 HIGHLANDER HEAT GAGE INDICATED THE ENGINE WAS STARTING TO GET HOT. I PULL INTO SERVICE STATION TO CHECK COOLANT LEVEL AND NOTICED COOLANT LEAKING ON THE GROUND. I WAITED FOR ABOUT 15 MINUTES TO ASSURE MYSELF IT WAS SAFE TO TAKE OFF THE RADIATOR CAP. I COULD NOT SEE ANY COOLANT SO, I PURCHASED A GALLON OF PRE-MIXED COOLANT AND POURED IN ABOUT 1/2 TO 3/4 GALLON TO BRING IT UP TO FULL. I MADE THE TRIP HOME WITHOUT THE CAR GETTING HOT, BUT NOTICED THE LEAK WAS STILL THERE. I HAD THE VEHICLE LOOKED AT BY A LOCAL TOYOTA DEALER AND WAS TOLD THE CAR NEEDED MAJOR REPAIRS. THERE IS A TECHNICAL SUPPORT BULLITIN ON THE ENGINE IN QUESTION. A 2.4 LITRE (4 CYLINDER) ENGINE COMMON ON CAMARYS AND HIGHLANDERS. I FEEL TOYOTA SHOULD HAVE TO REPAIR THIS VEHICLE IN LIGHT OF THE FACT TOYOTA HAS KNOWN...

VEHICLE SUDDENLY LEAKS ENGINE COOLANT TO THE OUTSIDE OF VEHICLE WITHOUT ANY WARNING OF OVERHEATING. LEAK IS COMING FROM A DEFECTIVE HEAD BOLT AND CANNOT BE FIXED. ENTIRE ENGINE BLOCK NEEDS REPLACEMENT. A VERY COMMON ISSUE AMONG 4 CYLINDER 2001-2006 TOYOTA ENGINES IN THE CAMRY,HIGHLANDER AND RAV 4 LEAKING HARMFUL COOLANT TO THE OUTSIDE OF VEHICLES THAT IS DEADLY TO HUMANS AND ANIMALS IF CONSUMED. NOT TO MENTION OVERHEATING OF ENGINE THAT CAN RESULT IN LOSS OF ENGINE POWER AND VACUUM THAT SUPPLIES POWER TO STEERING AND BRAKES. *TR

WHILE DRIVING ON THE HIGHWAY, MY ENGINE TEMP IN MY 4 CYL, 4WD 2003 HIGHLANDER SUDDENLY SPIKED HIGH. I HAD TO PULL OF THE ROAD. TOWED TO DEALER. DEALER SAID BOLTS ON SHORT BLOCK OF ENGINE WERE STRIPPED AND ALLOWED COOLANT TO LEAK OUT AND ENGINE OVERHEATED. I WAS AT 68,000 MILES, SO OVER THE WARRANTY PERIOD. I TOOK IT TO MY LOCAL DEALER AND THEY SAID I HAD A BAD WATER PUMP...I PAID TO HAVE THAT FIXED, BUT THE CAR STILL OVERHEATED. I TOOK IT BACK TO THE DEALER AND THEY THEN SAID IT WAS THE ENGINE ITSELF..THE SHORT BLOCK, SOMETHING ABOUT THE SCREWS WERE STRIPPED, THAT I HAD GOTTEN A BAD ENGINE WITH STRIPPED SCREWS. DEALERS SERVICE MANAGER TOLD ME THIS WAS A KNOWN ISSUE ON SOME 4CYL 2003 HIGHLANDER BUT COULDN'T HELP ME AS IT WAS OUT OF WARRANTY!!! THE SERVICE MANAGER CALLED ME BACK LATER AND...

THE SUV WAS OUT OF COOLANT & WATER AND MY HUSBAND TAKE THE CAR TO THE DEALER TO CHECK THIS PROBLEM AND FOR REGULAR MAINTENANCE (THE CAR ONLY HAS RECEIVED SERVICE AT THE DEALER, EXCEPT FOR TIRES). THE DIAGNOSTIC WAS THAT THE SHOCK BLOCK HAS IT THREADS SEPARATED FROM THE SCREWS (OR BOLTS). THE ENGINE HAS TO BE REMOVED IN ORDER TO CHANGE THE SHOCK BLOCK. THE REPAIR HAS COST $4701.31, BECAUSE IT WAS ALSO RECOMMENDED TO CHANGE THE OIL PUMP. PREVIOUS TO THIS REPAIR, THE SUV WAS TAKEN TO THE DEALER BECAUSE THERE WAS A RECALL TO REPROGRAM ITS COMPUTER BECAUSE THE CHECK ENGINE LIGHT TURNED ON (THIS HAPPENED TWICE). WE HAVE A FULL RECORD IN THE DEALER OF ALL MAINTENANCE CHECKS AND REPAIRS THE SUV HAD. *TR
