Hello, I have an 07 mustang V8 that's leaking coolant, overheating when driving and blowing white smoke. I'm not sure where to start. We just replaced a hose before all this started.

Does your radiator have the plastic coolant tank?

An external coolant leak shouldn't be hard to find. Top up the cooling system, start the engine, and let it idle until it warms up. Once the cooling system is pressurised, any leak will become apparent. Some pics would help.
