After almost two years, I have changed OEM stat, viscous fan clutch, water pump, temp sensor, coolant and cleaned water radiator...and the issue is not fixed. I'm getting crazy...

have you changed both temp sensors??

in this case you may have blocked water ways in the engine block somewhere..obviously something stopping the flow of fluid around...

I have changed the one that is in radiator hose, is there another one?

Hi,

There is a Water Temp stat in the ''alloy'' water
pipe under the Throttle Bodies.

No 18 on the attached link-

Replace this Temp Stat as its cheap.

If you still have high water temp then-

Do you have an Old Thermostat ?

If you do, open the Stat and 'fix' it
so that's it permantley in the Open
Position.

You require this, as to just remove the stat
can cause water cavitation.

Run your car and see what the temps
do with Stat permantley open.

If car runs Ok, then purchase the Tropical / MS
55 deg stat, if not, then you need to test
flow.

Hope that helps,

Regards,

The Gorilla.

Thanks a lot, Gorilla.

I replaced the stat using the OEM one. I bought that sensor but finally i did not change it because i had to remove the air intake.

Tomorrow i am going to remove front bumper, clean the AC condenser and replace the sensor n 18.

Also, i have ordered Motul Mocool aditive

Let's see what happens...
