1997 Jeep Wrangler engine and engine cooling problems

“1997 JEEP WRANGLER EXHAUST MANIFOLD. CONSISTENT DECREASE IN POWER, STUMBLING, AND POOR GAS MILEAGE. AFTER A WRECK I NOTICED THE MANIFOLD WAS CRACKED. BOTH THE INSURANCE COMPANY AND THE AUTHORIZED JEEP DEALERSHIP TOLD ME IT WAS NOT DUE TO THE WRECK BUT DUE TO FACT IT WAS A COMMON WRANGLER PROBLEM, AND IT PROBABLY HAD STARTED PRIOR TO THE WRECK I JUST HADN'T NOTICED IT. BUT SINCE THERE IS NOT A RECALL THEY WOULD NOT FIX THE PROBLEM. I HAVE FIXED IT. *TR”

“JEEP SUDDENLY LOST POWER ON HIGHWAYS WHILE GOING 55 MPH +., CAUSING A NEAR ACCIDENT WHILE TRYING TO COAST THROUGH LANES OF TRAFFIC TO THE MEDIAN. AFTER 10-15 MINUTES, I RESTARTED THE JEEP AND IT RAN FINE, BUT USUALLY ABOUT 20-50 MILES, IT WILL OCCUR AGAIN.. VERY HAZARDOUS. *AK”

“SAME AS EVERYONE ELSE....CRACKED EXHAUST MANIFOLD ON 4.0 L 6 CYL. JEEP HAS REDESIGNED PART. I FORMERLY WORKED WITH A 4X4 REPAIR SHOP, AND ALMOST EVERYONE THAT CAME IN WITH A 1997-2000 (OR SO) JEEP HAD SAME CRACKS. LEADING 4X4 MAGAZINES STATE "IT'S NOT IF IT CRACKS, IT'S WHEN". GIVEN THIS MANY COMPLAINTS, JEEP SHOULD BE PAYING TO FIX THEIR FLAW, NOT CONSUMERS. WILL REPLACE WITH AFTERMARKET COMPONENT, NOT JEEP'S. *JB”

“I AM IN THE PROCESS OF REPLACING THE EXHAUST MANIFOLD ON MY 1997 JEEP WRANGLER FOR THE SECOND TIME. THE FIRST ONE FAILED AT APPROX 55K MILES (OUT OF WARRANTY) AND CHRYSLER JEEP CUSTOMER SERVICE DENIED EXISTENCE OF A PROBLEM WITH THE EXHAUST SYSTEM, IN SPITE OF NUMEROUS REPORTS OF MANIFOLD FAILURE ON MANY INTERNET AUTOMOTIVE SITES. THE REPLACEMENT PART WAS SUPPOSEDLY REDESIGNED TO PREVENT RECURRENCE OF THE PROBLEM, BUT IT HAS NOW FAILED (MILEAGE IS NOW 110K, SO THESE ARE 55K PARTS!) AND MUST ALSO BE REPLACED. THE MECHANIC STATED THAT THE REPLACEMENT PARTS JUST CRACK IN A "NEW SPOT". CHRYSLER JEEP HAS BEEN TOTALLY UNRESPONSIVE TO WHAT IS OBVIOUSLY AN ENGINEERING FLAW IN THEIR PRODUCT, AND STICKING THEIR CUSTOMERS WITH THE BILL AND ANY RESULTING SAFETY ISSUES! NOT A GREAT WAY TO BUILD YOUR CUSTOMER BASE! *NM”

“CRACKED EXHAUST MANIFOLD ON 97 TO 2000 JEEP TJ WRANGLERS. MISSING EXHAUST "ACCORDING" MISSING RESULTING IN CRACKED MANIFOLD. RESULTING IN CAR FAILING US EPA SMOG GUIDELINES. IN SEARCH OF TJ OWNERS SHOWED MANY OWNERS HAVING THIS PROBLEM. *JB”

“CONSUMER NOTICEDE A LOUD NOISE WHILE DRIVING AND EXHAUST FUMES COMING INTO THE VEHICLE. CONSUMER TOOK VEHICLE TO DEALER FOR INSPECTION. DEALER INFORMED CONSUMER THAT VEHICLE HAD MULTIPLE CRACKS ON THE EXHAUST MANIFOLD, AND IT WAS NOT COVERED UNDER A RECALL. *AK *TC”
