Weird sound after turning off the engine

#1
Hello,

I bought a second hand Corolla 1,6 Hatchback generation E120 Facelift 1.6 VVT-i . It works fine but I have a question. When turning off the engine after driving for a while I hear a "slurping" (/ maybe a bit scratching) sound. Is there s cooling fan that should start after turning off the engine (which now maybe is broken?) or could that sound come from the AC, which then could be perfectly normal?

Any ideas?

Best regards
