Thanks Omegatoy, I change the oil once every year, as said in the car's book, it should be changed once a year or every 30.000 km, I am doing actually around 20.000 km yearly.

What is "flush additive", there are many additive on the market, you mean those whore are for the oil??, Kraft and similars??

What oil you use??, I am using 15-40 from the very begining, when the car was bought this oil was recommended. Also due to high millage I have to refill with 1 liter every 5000 km.

have to admit i dont buy it here is Spain, i buy them in england, however, a flUsh additive is a cleaning agent that you pour in the old oil run the engine for around 20 mins, then drain the old oil and change the filter and fill with fresh oil, basically what it does is completely clean the inside of the engine, it washes out all the old sticky burnt on oil and clears blocked up oilways?
I have some here but im  Near malaga which is a long way from Cordoba!!!
Forte engine flush is pretty good which is available on ebay, wynns also do one but mine is trade only because its stronger, im sure others will post up what they use

I guess this is the liquid

I will buy it then, other thing,  someone has recommended is to change/revise the viscous but I really do not know what is that or where is it.

yep thats the stuff, very good!! does your car have electronic ventiladors in front of the radiator? it should, these are controlled by a switch in the radiator on the right hand side as you stand at the front of the car, it is not unknown for this temp switch to malfunction, do you hear the electric fans when the car gets hot?

Yes I hear a second ventilator going on, and also the Intercooler ventilator.

Once I stop the car, usually in summer the still keep going for about 20m

I've put the Forte flush through mine a couple of times now, and it hasn't made any noticable difference - the car still goes up over 100 degrees if I give it the slightest bit of power on a hill.

What's the name of this stronger flush please Omegatoy?
