On the 2000-2001 Ford Mustang 4.6L SOHC V8, early 4.6L SOHC Mustang GT models used a composite intake manifold that is known to crack around the coolant crossover/thermostat area, causing sudden coolant loss and overheating. This was a widespread Ford modular V8 problem and appears repeatedly in owner reports and service literature. Owners typically report coolant smell, visible leaks at the front of the intake, steam, and rapid temperature rise.
Pressure-test the cooling system and inspect the intake manifold crossover and thermostat housing area for cracks or seepage. The durable fix is replacement with the updated Ford or Dorman intake manifold design that uses an improved aluminum crossover. If overheating occurred, inspect coils, plugs, and head gaskets before returning the car to service.

On the 2001-2004 Ford Mustang, manual-transmission New Edge performance models are well known for throwout bearing, clutch fork pivot, and front bearing retainer wear that causes chirping, squealing, or grinding noises when the clutch pedal is depressed or released. On 2003-2004 supercharged Cobras in particular, owners frequently report repeated throwout bearing failures and clutch engagement issues. If ignored, the problem can progress to poor clutch release, transmission input shaft wear, and more expensive clutch/transmission service.
Confirm whether the noise changes with clutch pedal position and inspect for clutch cable/quadrant adjustment issues before removing the transmission. Repair usually involves replacing the throwout bearing, inspecting the clutch fork and pivot ball, checking the bearing retainer sleeve for wear, and replacing the clutch/pressure plate if contaminated or heat-damaged. Many owners upgrade to improved aftermarket bearing retainers and quality clutch kits during service.
