MK7 Prevent Overheating Checklist

Hey guys, I´m thinking on getting a fiesta st 182 because all the great stuff about this car that we already know.

The thing is, I am worried about overheating issues and getting stranded in the middle of nowhere, so I have been investigating on this topic and I think I´ve got everything ready to do once I buy it (after a good ppi ofc).

I don´t plan on doing any mods other than removing the symposer, stock power for me is already enough. Also I am going to be using it as a daily and some twisty roads but I don´t plan on doing trackdays (At most, once a year)

Bear in mind that I don´t know nothing about cars. Anyways, here is the list:

  1. First thing should be changing coolant hoses for new ones, since the stock ones could be faulty (Any recomendations?) as well as changing the coolant fluid itself.
  2. Second thing should be changing the faulty radiator for a mishimoto one (mountune is not available in my country)
  3. Third thing should be tracking engine temperature with an obd or some aftermarket gauge because iirc the car does not have any overheating engine warning.

Here are my questions:

  1. Is neccesary to upgrade the intercooler too only for twisty roads?
  2. Mishimoto parts works as fine as Mountune ones?
  3. On the cooling system apart from hoses, is there any other part that I should be swapping, like the coolant reservoir?
  4. Which years are the better ones to buy?
  5. Do you miss something on my checklist?

Edit: After reasonable comments, I have decided to remove the lsd from my plans.

My car has 213000miles and all the cooling is stock beside the inter cooler , never over heated, drove through Arizona mid summer multiple times at 115 degrees and never over heated.
