next step on the water loss if there is no evidence of it leaking is take for a dye test and or listen to the exhaust for a small hissing noise and or popping

ok i'll check the o2 sensor.
What about the water compression? Do you mean to press the big tube going from radiator to thermostat when engine hot?
If you are talking of that, yes i did it. It's pretty hard, I can't totally press it, but I can press ah half of its diameter, more or less...is it correct?

if its not taking water from the overflow it may not be pressurising properly is there any signs of a leak if not it has to be going through the exhaust. that's why I want you to listen at the back of the exhaust for any sort of hissing or popping.but the compression test is on the cylinders. you need a compression tester to do it from where the spark plugs are.

Also check that the radiator cap is sealing at the lip. Water will expands with heat and when it cools it drags air in instead of water from the tank.
My advice is: not to follow my advice.

Hi all,
I just finished to check all you guys said, nothing came out. The car still has the same problems exposed in the first post.
The engine start to show those problem only when it's getting hot, otherwise, when cold it's perfect!
@ kevin: i just took out the O2 sensor...sorry but mine has not fins...check the pic

Considering the O2 sensor has probable been in there since it was made it would be an ideal time 2 put a new one it anyway, regardless if it fixes the problem or not
Time is never wasted when your wasted all the time

Ok thanks, I will buy one from the site posted by Kevin.
Do you guys think it's better to buy even a new coolant temp sensor? We tried three of 'em, but all were old and extra used.
Maybe with a new one the problem could be fixed.
Today I tested much better my problem and I've seen that this temperature (photo) is the limit to a good performance. A lil bit hotter than that and the car does what I explained...

Those temp gauges mean nothing, mine normally if I remember correctly sits about half way or a bit more.
