“I was driving on the highway and noticed that the steering was pulling to the left. After a short while I could not manage the steering. When I pulled over in the brakedown lane I noticed that the right front tire was toed in. When the tow truck came we noticed that the frame was cracked and rotted at both wheel mounts and the the right front mount was the worse. We also noticed that the motor mounts were all rotted and the overall front section of the frame was rotted which prevented any repair.”

“This is my mothers pickup but she asked me to report it and try to find an answer. She has had the pickup for years (she bought it in 2003)...she bought it from a neighbor. After a few years she started having a problem that no one (not even the dealership) has been able to fix. This has happened many, many times. Sometimes when she goes to stop, the truck will suddenly rev up and try to take off. Several times this has almost caused accidents (it has jumped out into traffic, almost rear ended other cars, etc). I've contacted the Ford company and they have told me to go to the dealership. …”

“The metal tubes for the engine choke heater, rusted out right above the aluminum head. Was told that there is no way to fix the problem, except to replace the head with a new one. The head will cost at least $250. My truck is a 1999 Ford Ranger xlt with a 3.0l. Was told the only way this tube would break was from a crash, or from rusting from the inside. I know my truck has never been in a crash, kind of odd that only the tube has rusted and not more engine parts. Anyone else have this problem.”

“I had a 1999 Ford Ranger with a 4.0 liter engine a v-6, it started running rough at 95,000 miles. I took it in to the dealer to be repaired. The next day I was told there was water in # 4 cylinder. They took both heads off and I was told that both heads had cracks in them I went to look for myself I verified that both heads were cracked in the same location a crack on # 4 cylinder and a crack on # 1 cylinder. I was then shown a cracked head off a Ford explorer with a 4.0 liter engine same crack same location. …”

“My 1999 Ford Ranger 4x4 with 3.0 liter flex fuel engine began sputtering, running rough and overheating two days ago. I took it to haldeman Ford to be checked. They told me today there was water/coolant in at least one of the cylinders and the head(s) may be cracked, and I need a new or rebuilt engine. The truck has just over 95,000 miles on it. I had oil changes, coolant flushes, etc. At regular intervals. From what I have read on your website, and heard from others, this is a problem with the six cylinder engines Ford used in rangers and explorers. …”
