Sense / No sense ?

You forgot the clamp after re-attaching it lol

I mean it’s a poor man’s coolant flush.

I mean, it worked... You'll need to put a hose clamp on the radiator end, and you better hope no cops or nosy neighbors saw you doing that. I don't know what country the video was taken in, but in the US, if you get caught doing that, you'll be slapped with a big fat fine.

If you put cold coolant into hot engine your cylinder head may crack.

You know they have cheap Chinese harbor freight suction machines now that allow you to work cleaner and not contaminate everything.

Open circuit and let a bunch of poison to animals get on the ground and seep into the groundwater? You’re an idiot

None

I mean, if it works..

if it is filled with water and you want coolent

Electric Car ?

R E T A R D.

I suppose that's one way to make sure u got enough antifreeze in ur car

Gatorade is good for your cooling system ?

Nonsense!!!.. Please don't do this..

Sense as long as the coolant used is a 50/50

Forgot the clamp

If it drops below 0 degrees you don’t take any chances. Complete flush.

Better sense

No senseに見えて、 スタンドのバキューム交換より綺麗に抜けてる可能性あるよね。 容量わかってる人ならアリだと思う。

También olvidó el termostato

I would have diluted the fill 50/50 before pouring it into the hose.

It should be done on beach or in bathroom

Makes sense to me. I don’t know if it’s necessary.

sense in emergency car owner might used water as engine coolant and to flush the water and refill the coolant without hazzle he can use the process where old one flushes while new one gets filled up and acts as coolant

Sense, Flushing out the water and replacing it with coolant

was that necessary

Standard process to change the coolant. It is recommended that use the water after removal of old coolent to clean the pipes and fill the new one after cleaning with water.

Try orange juice next time

谁教你这么换冷却液的

Good idea as long as you can purge all the air bubbles out of the system so it doesn't overheat and you have enough for the heater core.
