“I was driving home when I smelled coolant. When I got home and checked for leaks I found that the intake manifold was cracked and leaking coolant it to the engine valley. My moms '96 cougar and friends '98 mustang did the same thing. They had to have the manifold replaced.”
NHTSA complaint #10074545, filed 2004-05, 62,000 miles“We took our 1998 6 cylinder mustang in for an oil change. It has about 90,000 miles on it. We were told that it is leaking fuel and that it is a safety hazard. We now have to spend $1000 to replace the fuel rail, both valve gaskets, valve cover gaskets and fuel injector o rings. Plus a significant amount on labor. We were told that our car/engine will catch fire, if we do not replace these parts. This is my daughter who is in college's car. How can they have such a horrible design and if we replace the parts is this going to be repeated? …”
