the fans should turn on at no hotter than 220 degrees then it should cool down to around 195 or so, then do it all over again. but if the cooling fans are running and you are still gaining temp then there is either a air flow blockage on the outside of the radiator or an internal coolant blockage inside the radiator. visually check for bugs, dirt, foreign material blocking air flow anywhere in front of the radiator including the A/C condenser. If it is all clean then you will have to get the radiator flow tested.

Temp gauge should be no higher then 150 degrees .. Never use plain water in your radiator ,always use a top brand Anti -Freeze such as Prestone !!

Whoa friar this isn't the 50's any more, today's cars run very warm, with a base thermostat of 197 degrees. Your right about never running plain water, it fouls up the PH in the cooling system not to mention the boiling point.

My thermostat, GM 50/50 Coolant, Radiator Hoses have been changed by GM Technician and the temperature did read just about halfway between the 2-3 marker, although now after being done, the reading is right at the middle or on the 3 marker and when idle in park it slowly rises. This has never occurred - why after this... ?

Do you know what temp thermostat was in it before and what he put in it as a replacement. It is a possibility that it had a cooler thermostat in it then it was suppose to have and he put it back to stock temp. Just to make sure check the coolant level cold. If it is low add coolant only, no water.

The temp of the thermostat when it was replaced was 195 degrees, and it was replaced with the same. That is why I cannot understand why the gauge read higher than before. I will check and see if possibly the fins on the Condenser and radiator are clogged with debris, however it operated fine before, so I have doubt that is the problem. If it loses coolant what would cause that ? I have not filled it with coolant as of yet. Would the water pump not operate normal and leaks be inside the pump. There is no water/oil mix so the head casket is not the problem.

I got a 2001 Pontiac Grand Prix it usually runs at the temperature of that 100 that 180 but I start freaking out when it gets anywhere near 210 and the only reason I'm doing this is if I turn on the air conditioner something you know I run good and that I was so just start eating up so I have to put it back on heater and run the heater on on the front defrost and then it goes back down to about a hundred and ninety-five 280 again but here now I just flushed it out clean the coolant and now it seems to be staying at around 2:10 is this a good or a bad thing

Okay I have a 2001 Pontiac Grand Prix what it does is I usually run at a normal temperature of 180 every once while it will go up to 2:10 and when it starts getting up to 10 I throw on my heater to make it come back down what seems to be my problem I just now flushed out the radiator and putting new coolant 50/50 and some reason it's now staying higher since I've done that so what seems to be the problem with that
