well, I flushed the coolant 3 times, changed the pump (for one with 5 blades, I had one with 7 blades in the car before) the thermostat, and the car overheats in 2 minutes, I do not have de owners manual, and did not open cold star device (
). I read it today
yesterdat I found the problem I did not have heat,by the blower fan, so I did have air in the circuit, I went through several bumps, touched the coolant hoses and played with hot air selector. and the car asked me for 3 litres of coolant more!!!!, that was the problem.
Now is ok, PROBLEM SOLVED.
thanks
