Well heck, my dad had an 87 Ranger that he really only changed the motor oil on.There isn't a manufacturer recommendation, so I change out what is in the reservoir every three years along with the brake fluid. As long as you are changing some of it out every once in a while, I think you will be good.
It blew the water pump around 100,000 miles. The coolant was the old green, which I think was 2 or 3 year coolant. It was nasty. The power steering was nasty too. The hoses started to leak just a little after maybe 120,000 miles. I pulled slot of the fluid out of the reservoir and replaced it with something with stop leak in it. It stopped it. Seemed a tad quieter, too. Brake fluid was never changed. But a line blew out around 120,000 miles. Never had another problem with though. But those systems didn’t have ABS, so no really expensive stuff to go bad. So I guess my point is maybe thorough maintenance isn’t all that worth it.
