KIA BESTA 2.7 spends a lot of water and heats up

Friend:
Thank you very much for your tips ... It is a great support for my Susu Act advice say many things but nobody is worthy ... you are worth gold ..

Another mechanic told me that it was normal to spend water at this time is true ??????????
prefers to spend water instead of getting the thermostate.

sometimes passes the compression depends on where the crack is

The only problem that the KIA had at 6 years of having it 0km, was that the lid was punctured between the two closes of valves, the solution was to take the lid to a rectified engines workshop and they made hydraulic test and detected where the loss was. The lid was not corroid because he used a good refrigerant but it was the only problem in 10 years. The lid because the concavity of the cylinder that lost is like running through the water and combustion hydrogen.

Hello "jl" thanks for the discomfort good drawing, let's see where he says a closed lid is to the radiator, where the red arrows are to the engine. Where he says water current, where he is? vehicles with 2 thermostats and this is the time that I do not understand what they serve 2 if with 1 enough ... I reiterate my thanks for your kindness
