i want to change my cooler fluid, and i wanted to ask first, about some instructions like, how many liters do it take till is full, what kind of a mixing should i take, and where can i release the old fluid?

anyone who gives some info,

thanks
peter

what kind of engine is in the car ?
Cause that is important if you want to know how much should be available for a refill.

The best point (at least the fastest) is the bottom hose of the radiator.
Some engine's also have a plug on the engine-body for further drainage.
But then again, what type of engine is involved.

The mixing is for you to decide, i personally use pure cooler fluid because it prevents the engine much better against frost and overheating, and avoids corrosion inside.

Where you can release the old fluid, i don't know for you'r country.
It is toxic, i spilled it on the gras 2 year's ago, only this year some new gras grow on the same spot.
But as i said, i use the fluid pure, i don't mix it with water.

If the old fluid is out, re-assemble the bottom hose of the radiator (and if apropiate the draining plug on the engine body), then dismount the top hose of the radiator on the engine site, and pour the new fluid in that hose, so you fill up the radiator first.
Then when this is filled up, reconnect the hose, and fill the cooler fluid tank.
Leave the cap of this tank, start the engine, and keep a good eye on the level of cooler fluid in the tank.
It might drop like crazy, so fill it while it does so.
Also try to keep an eye of the engine temperature gauge, and do not play with the gas pedal.
If the engine become's to hot for what is normal, shut off the engine and let it cool down before proceeding.
When everything seems to work, the fluid level is not droppig anymore, engage the interior heating, because that little radiator needs to be filled to.
Again keep monitoring the fluid level in the expansion tank.
When al this is done, the air must be taken out of the cooling system.
How and where depends on the engine type.
