Leaks:
Sweet smell:

No... and if it has all the undercover you'll never see a spot on the floor... i had to take mine in for a radiator under 20k miles (24 model)... check for a sweet smell after a decent commute or pop the hood and look around for dry crusty white ish splatter... coolant kind of looks like battery corrosion when it dries

Pros: check for sweet smell

Cons: radiator failed under 20k

Vehicle: Mazda 3

Mileage: 32186 km

Overheating:

I swapped the radiator in mine when old one broke and filled with new asian green type coolant, and the aluminum radiator has made a world of difference. Also check the air filters.

Pros: aluminum radiator difference

Overheating:

Use good quality maintenance items and replace anything worn out, nobody is going to give you marks off for Koni or Bilstein shocks, or radiator that isn’t Mazda original. Avoid obviously tacky/non standard looking cosmetic items, try to stick with parts that at last look like they could be part of a factory car.

Pros: non-Mazda original radiator acceptable
