hello everyone,
my problem is my temp is constantly moving from R to A while driving at a constent speed. i even pulled over to check an see if the vechicle was overheating, it wasnt but the fan was on.once the fan comes it returns between the O and R position an then gradually moves up to the A again. i have replaced the waterpump,coolant temp sensor,coolant temp sending unit, the degas bottle cap,the intake with the aluminum thermo housing, the thermostat, and flush the system as best i could,replaced the coolant line behind the waterpump. so you see i dont know what else to try. I REALLY NEED HELP. THANKS

The stock gauge sucks. Try hooking up an aftermarket gauge to somewhere along the coolant lines.

^ this is true as well

But take off that plastic decorative shroud above the radiator, and inspect the front of the radiator. Maybe there is a bunch of debris there that you can spray off with a hose... I've done this on a few cars for the same reason you describe and it usually works wonders
