Nice pics
Coolant color is not universal.
So you do have to look at the label
Silicates are 2 year change intervals, usually Green
OAT(organic acid) are 5 year, usually Red
HOAT(hybrid organic acid) are 5 year but often said to be lifetime, usually Gold
But the fact of the matter is that cooling systems will leak, fittings, thermostats and water pumps will fail, so lifetime isn't for the car or engine, it's for the cooling system, lol.
I drive older cars/trucks, so run 2 year coolant because I know I will have something fail and have to drain or get new coolant, I am cheap
If I get 2 years then don't mind paying the $10-$15 for some new 2 year
Now if you are switching "colors" I would refill with distilled water not coolant, and run the vehicle a few weeks that way, then flush and refill with your choice of coolant, no anti-freeze protection with water only, so heads up!!!.
I often do this water refill after doing any engine work that required any parts of the cooling system to be disassembled
Like I said I am cheap and if there is a leak I want to lose water not coolant, lol.
