Dear All.
I have an automatic Aerium Suzuki with Motoro 2.3 and the problem is that the temperature was raised (without generating damage according to my mechanic).
The mechanic checked:
1. The radiator: He told me that he is good.
2. The water pump: despite being in good condition I changed it anyway.
3. Thermostat: I changed it to an alternative one.
After this and after a few days, the T ° uploaded again to the top, so I returned to the mechanic, where I recommended the thermostat to rule out that it is. I left it then without thermostat and everything worked well, the T ° was not uploaded even on the road, it lowered more than medium (marking 1/3 more less) and returning to the city returned to the medium (where I understand it must always be).
Finally, I decided to buy a new original thermostat and took it to the mechanic. He put it but immediately rose the t °.
We took the thermostat and tried it but it opened correctly.
He checked hoses and all normal, so much so that the mechanic told me "the truth, I don't know what it can be" and left the car without thermostat so he can walk.
Does anyone have any idea what the problem could be? And how could it be solved?
Of course, thank you very much for the help.
