Replacing coolant parts as a safe measure

I believe that we often forget that dealerships are paying hourly wages, sometimes health benefits and other benefits, plus paying for extremely expensive equipment, insurance coverage, legal expenses, etc, etc, etc. all while being in business to make a profit (some times enough to satisfy shareholders). Plus paying for ongoing training for their staff. So, obviously, it will cost more to have them do a service than what most small independents need to charge, or what a DIY can do it for. While a job might be simple, they are often using equipment that insures it is done correctly and completely (such as brake fluid changes on a Prius).

 

Yeah I wonder, would the do the full brake fluid change, which I believe replaces the fluid in the brake booster components? For sure they'll be using Techstream, and maybe a high-tech vacuum extractor.

My "equipment", doing the non-Techstream method, was"

10mm box wrench
8mm box wrench
length of clear tube with bleed valve grommet on one end
largie/empty mayo jar with lid, with hole drilled in lid
Largish syringe with clear tube extensiion and skinny pippet nozzle (for basting out reservoir)

Plus floor jack, jack stands, wheel chocks, impact wrench with 21mm socket, the usual rigmarole for DIY raising the car
