To answer oparationAlfas question, the milage on the car is 145 000Km and its a 2002 model.
Rockhopper - when the 90 mark is reached, the fan kicks in and sometimes goes down, then the fan stops. Then the 90 mark is reached again, the fan kicks in but it just stays there on the 90. After a couple of minutes it continues to climb going up to the 3/4 mark, at this time the fan is at full speed, then it just stays between the 90 and the 3/4 mark, the temperature rises immediately if you klap the car to the 3/4 mark. so I have not been driving the car at all.
thanks for your advise, will have the thermostat replaced as well as the pump and advise.
