wondering what would happen if i disconnected the hose at the top of the coolant expansion/refill tank and started the car, let it potentially drain into a bucket while constantly refilling it with premixed coolant

can i do this kind of flush ? or will it not flow until you tap the gas pedal ?

sorry for the stupid question,. i just have a leftover jug of nissan long life coolant from another car and want to use it ...

 

Just open the drain on the radiator and drain it and refill it.

 

well i dont have a short pan to put under the car and i would need more coolant than my jug to refill it, i dont even see a rad cap anywhere , refill through the bottle ?

if i can i rather do it with the expansion bottle hose this way i can stop as soon as i run out of fluid

bad idea ?

 

It should work fine that way.
