Final update.
If you are unable (like me), to remove this hose from the radiator, then there is another easy way to change to cooling fluid.
1. Remove the thin hose that goes to the upper side of the expansion tank.
2. Have a garden hose ready.
3. Start the engine. You will notice that as soon as the engine starts the fluid comes out of the thin hose.
4. Continuously refill with water, (do NOT let the tank empty).
After a few minutes with the engine at idle, the fluid coming out will become more and more clear. Remember that the car has almost 6 liters of it.
5. Repeat the above 3 - 4 times so the water that comes out is as clear as the one that's going in from the garden hose.
6. Turn the engine off.
7. Get 5 - 6 liter of distilled water in a container ready to refill the expansion tank.
8. Start the engine as above, but this time refill with the distilled water.
9. When you have used all the distilled water, continue with the Paraflu.
10. You must use 3 liters of it, so QUICKLY before the engine circulates the diluted Paraflu and it starts to come out of the thin hose, put the 3 liters in and the thin hose to it's place on the tank.
Don't forget to replace the metal ring that holds the hose in place.
If the expansion tank is dirty from the inside and has there pink deposits, you can do the following after #6.
a. Remove the thick hose that goes under the tank
b. Remove the 2 screws that hold the tank in place and get it in your hands.
c. Empty it and pour 2 spoons of rice in it.
d. Place the closure in place, secure both exits with your palms and start shaking it, to every direction, until the rice hitting it from inside removes all this pink deposit.
e. Wash every bean of rice thoroughly.
f. Install it in place and reconnect the thick hose securely.
