Oil cooler installation

[MustangNoob]

Hi folks,

I'm thinking to install an oil cooler on my non-performance pack GT. I will go with ford's part.
I saw a video on yt that someone installed it. What is this grease type substance the oil adaptor has? Is it anticorrosion grease ?Does it has to be flushed out prior installation ?

After installation how does the car know it has an oil cooler in order to properly display the oil temp ? Is the temperature inferred/calculated to actually measured ?

Thanks

Apparently this has been discussed in other threads and the only way is to reprogram the PCM. It hasn't been able to be done yet.
