Slowly using Coolant From Reservoir!?
Hello
I noticed a few weeks ago that my car use some coolant from the reservoir...when the car is cold I filled up to the full mark..after some hard driving the coolant in the reservoir goes a lil bit higher and when It cools down it comes down..But I have noticed that It's missing some since the coolant now is way below the full mark..?bad radiator cap???
No bubles
No Milky oil
No smoke
No overheat even beating the h... out of it on hot weather with A/C
what could be the problem? thanks

Sounds like that radiator cap. I have the same problem and I have pressure tested my coolant system and everything was fine. So the only thing left is the radiator cap. Make sure you dont have it tightened all the way down because it needs to vent that is also another problem.

The Radiator cap is a service item. I had a pressure cap tester for so many years I wore it out. Anyway, the caps on average are good for about 30,000 miles which means the radiator caps on most cars are shot. So, it is a good habit to replace the cap when changing coolant.
A cap that is allowing vapor to escape will cause the coolant level to go down but only slowly.

1.1 bar is incorrect usage of the term. 1 bar is approximately atmospheric pressure so 1.1 bar would be almost no pressure - the pressure in a flat tire. 1.1 barg (meaning 1.1 x close to atmospheric pressure) would be 15.9 psi which is the correct pressure cap for the Evo.
