I HAD WHAT SEEMS TO BE A SIMPLE COOLANT LEAK BUT IT TURNED OUT TO BE THE PLASTIC INTAKE MANIFOLD CRACKED. PUTTING A PLASTIC PART ON TOP OF A MOTOR SEEMS TO ME A FAILURE OF ENGINEERING ON THE PART OF FORD. I DID NOT RECEIVE ANY CALL BACK FOR THIS PART. I DID SOME SEARCHING ON THE WEB AND FOUND THAT MANY FORD OWNERS HAD THE SAME PROBLEM. I PLAN TO CALL FORD COMPANY ON MONDAY. DO YOU HAVE ANY INFO FOR ME ON THIS SUBJECT. THANK YOU. *TR
