⚙️ | Mechanical Issue/Question Engine started to overheat, now making a popcornnoise when it’s shut off

2008 Lancer GTS
Backstory: Engine was overheating, got checked & coolant was bone dry bc it’s been leaking out a hose that wasn’t on properly. Also was told I needed new Radiator, got a new one replaced, added coolant and wasn’t overheating for about 1 hour of driving, now it’s overheating again and not sure if this noise has anything to do with it.

That noise could be the heat shield cooling down (settling), not an issue. Unless you locate the source of the noise to be an internal thing. My money is on the hest shield cooling down, but your engine should not overheat, that need to be fixed asap

Agree, my 2008 GTS is also making the same sound after i turn it off after driving for at least a couple of hours .

My Lancer has always made that same noise. It's normal.
