2003 TOYOTA 4 RUNNER Engine And Engine Coolingengine Problems

2003 4 RUNNER V6 HAS LOUD TICKING NOISE COMING FROM ENGINE CONMPARTMENT. I RAN IT BY THE DEALERSHIP 1 WEEK AFTER PURCHASE TOO SEE WHAT THE PROBLEM WAS. SERVICE MANAGER SAID IT WAS NORMAL. APPROXIMATLY 2 MONTHS LATER REAR SEAT WAS SQUEAKING. MADE APPOINTMENT WITH DEALER HAD THEM FIX THE SEAT AND DIAGNOSE THE NOISE COMING FROM ENGINE COMPARTMENT AGAIN. THEY FIXED THE SEAT AND WAS TOLD IT WAS THE INJECTORS MAKING THE NOISE. I TOLD THE SEVICE MANAGER THAT I WAS NOT HAPPY WITH THE QUALITY. THE 2002 4 RUNNER IS VERY QUIET. I AM PLANNING A RETURN TRIP TO THE DEALER WHEN I FIND ENOUGH INFORMATION ON THE PROBLEM.*AK

WHEN ACCELERATING THE ENGINE MAKES AN ODD NOISE THAT SOUNDS LIKE THERE IS AN EXHAUST LEAK. I ALSO INTERMITTENTLY HAVE THE "ROTTEN EGG" SMELL INSIDE THE VEHICLE. I TOOK IT TO THE DEALER TO HAVE IT EXAMINED AND AFTER THE SERVICE MANAGER DROVE THE VEHICLE FOR 1.6 MILES, HE TOLD ME "THEY ALL SOUND LIKE THAT." IT SEEMS ODD TO ME THAT A VEHICLE DESIGNED TO BE SO QUIET WOULD MAKE SUCH AN ALARMING SOUND WHEN ACCELERATING. I ALSO FIND IT ODD THAT, IF THERE WERE NO EXHAUST LEAK, WITH ALL THE WINDOWS CLOSED, THE ROTTEN EGG SMELL OF EXHAUST IS STILL ABLE TO SEEP INSIDE THE PASSENGER COMPARTMENT. I HAVE READ OTHER COMPLAINTS STATING CUSTOMERS SHOULD USE A "BETTER QUALITY" OF FUEL. I HAVE ONLY USED HESS AND MOBIL 93 OCTANE IN THE 3 WEEKS THAT I'VE OWNED THE VEHICLE. I ASSUME THIS IS A GOOD QUALITY GASOLINE, BUT...

WHEN ENGINE IS COLD THE BELTS MAKE A LOUD SCREECHING NOISE UNTIL THE CAR WARMS, THEN THE CAR MAKE A TICKING SOUND. TRUCK IS A V6 MODEL AND HAS BEEN IN FOR THIS REPAIR 4 TIMES, DEALER SAYS TOYOTA IS AWARE OF THE PROBLEM AND DOES NOT HAVE THE PROPER SOLUTION YET, THEY SAY IT HAS TO DO WITH THE BELTS AND TENSIONER SET UP. UNACCEPTABLE RESPONSE FROM TOYOTA. *NLM

ENGINE MAKES A TICK, TICK, TICK NOISE WHILE RUNNING. SOUNDS LIKE SOMETHING KNOCKING INTERNALLY IN THE ENGINE OR AN EXHAUST LEAK. DEALERS REPAIR SHOP SAYS ITS NORMAL. I DON'T BELIEVE THEM. I SUSPECT A FUTURE PROBLEM OR FAILURE OF A COMPONENT. *JB

2003 TOYOTA 4-RUNNER V6 LIMITED GENERATES THIS UNUSUAL (TICK, TICK, TICK) ENGINE NOISE ESPECIALLY WHEN ACCELERATING. IT SOUNDS LIKE A LOOSE PART IN THE ENGINE BLOCK. THIS NOISE IS ESPECIALLY NOTICEABLE WHEN THE 4-RUNNER, DRIVEN BY MY WIFE, ACCELERATES BY ME OR WHEN I DRIVE WITH THE WINDOW OPEN NEXT TO A WALL. WILL THIS NOISE AFFECT ENGINE PERFORMANCE AND SHORTEN ENGINE LIFE? VERY CONCERNED CUSTOMER. *JB
