My 2000 Mustang gt overheated while I was driving back home, on a ten mile journey a couple days ago. Until this incident, my Mustang had never overheated. I bought the car last sept. I used hose water at gas station to cool it first on hood then once my engine looked cooler, I filled the radiator (thinking we'd flush the cooling system when I got it home) water emptied as fast as I poured it in, from intake manifold behind what looks like the thermostat housing. My car is my only transportation. Now I'm not sure what to do. Because I used all my money to buy this car. I can not afford to fix this. My situation appears identical to several on your site, such as this one I just copied from one of the complaints posted:oct 08, 2013 - lexington, SC - engine and engine cooling while driving vehicle, engine began to overheat. Steam rolled from under the hood. Discovered crack in manifold where it connects to thermostat housing. Coolant dripping on the engine; I do not know if internal components are damaged.
Vehicle was parked and turned off. Fire started in engine compartment. Witnesses said it sounded like the car was trying to start itself. Total loss. Damage was worst on the passenger side of the engine compartment centered in the area in front of the wheel. Security camera of incident shows smoke then fire starting at the front passenger side.
My car completely shuts down while driving. It has happened 4 separate occasions. The car has been serviced twice for this and the dealer's service dept is currently trying to determine the problem, but no results have arrived. This is a serious safety concern due to high potential of a fatal accident resulting by the car shutting off while driving creating no power steering or brakes. The dealer's service dept has supposedly fixed and/or replaced 2 separate parts that were the supposed culprits, but the problem continues. Incidents occurred in 2002, 2005, and 2006. This problem, as you can see by dates, is random and happens without any warning, such as "idiot" lights coming on prior or engine hesitation, and apparently is just as complicated to diagnose.
While cleaning my spark plugs, I noticed the number #3 spark plug had oil on the spark plug thread. When I put my finger into the number #3 cylinder hole oil showed on my finger. The number #3 plug was also fouled compared to the other new plugs. This could lead to engine damage or a fire in the engine area. I heard that Ford had a service bulletin on this problem, but I called Ford and they said there is no service bulletin on my car for this problem. I was told by many owners that Ford had a valve cover buffle to pcv valve problem on 1999 and 2000 Mustang 3. 8, but they will not do any thing to correct the problem. I was told my many owners that they mod. And removed the pcv valve and replaced it with filters to stop oil getting into the cylinders. This would make it illegal and would like to see the problem corrected properly. I was told that the 2001 valve covers and up corrected this problem.
When applying brakes gear skipped and and brakes became loose. No braking power. Also, consumer was having electrical problems which caused defects in the alarm.
