Things that affect temperature :
Thermostat
Radiator cap
Proper coolant
Water pump

I'd replace the first two , then flush radiator and add new coolant

 

the sensor that turns on the fan is the same as the coolant sensor? where is it located?

the thermostat is changed and the coolant flushed too, not sure abt the water pump but no leaks anywhere at all though.

 

The coolant sensor = Temp gauge sensor .... I'm assuming it's working OK but if you really feel the need to change it go ahead ...

 

lets c.. thts the only thing left to change before i get onto water pump n all....

 

Just a shot in the dark here. Are you having to add coolant frequently? I have a leak that I recently found to be a leaking water pump.If not have you burped your radiator? My guage does the same thing yours does but usually when I am running low on coolant. Food for thought.

 

no my coolant is fine.... burped the rad too.... i just changed the sensor too... seems a lot better now.. but im ready to do the t-belt and water pump next ....

 

ok just wondering.... now the guage just goes up when im idling or at a stop... sign of weak water pump?

 

no help on this?

 

how far up does it go ...whats the outside temp...slight movement normal 1/4 gauge not

 

up till the markings towards H... not over tht.. thts when the fan kicks and it comes down... guessin its normal...
