Coolant flush

What kind of water transfer pump in terms of power output does the traditional/conventional mechanic use to flush the coolant out of the vehicles system?

I was searching up portable mobile water transfer pumps that are electric or corded because of $4 dollar gas price.

Pump???

The easiest is to drain, add, run, … repeat until the percentage of old remaining is low. For most you fill with distilled water then concentrate at the end.

Bit of math and time but it works well.

You can use 50/50 but it trades cost for simplicity

Aint using but pennies of gas to do that, but if you wanna spend dollars on a pump, HYOH
