Does anyone really do this to their cooling system?

Ok guys I have said this before I will repeat proper flush and fill procedures.
Don't use chemicals. find a good rad shop and they will do a reverse system power flush with compressed air and water. this goes thru your heater hose in reverse flow and flushes out your complete system.

(your top hose is removed and a down spout is added to rad to point the water coming out down to the floor.)

after the water runs thru system for a while the compressed air is hit and it "flushes" out your system and boy is it dirty!
then when your whole system has been flushed numerously add in 6 litres of anti freeze and 1 in your overflow. then top up with water and your good to go.

Most people say you just need 50/50 but it depends where you live. Extreme hot or cold weather will dictate how much antifreeze. so if you live in arizona or Canada and the northern states, 6 liters plus one in the overflow will help you as low as -51degrees C and +51degrees C.

also change your thermostat and cap every 2-3 years when you do the reverse power flush.
