I'm planning on flushing out the coolant on my BMW sometime next week.
I don't really want to take off the water pump hose and the other hoses to let coolant out. It'll create a big mess, which I don't really want.
So, I plan on unbolting the radiator drain plug and letting all the coolant drain out the radiator. Then Adding 2 gallons of distilled water and bleed the system/ turning the water pump on without starting the car.
After I'm done bleeding the system and draining the water out, I'll add the 50/50 BMW coolant.
Can I harm the water pump or other coolant items by just bleeding the system with distilled water?
If I turn the water pump on when there's no coolant in the system, can I harm the water pump that way by running it dry?
Any other things I should be cautious of?
