That is about normal. The fan does not come on until 212. Is the cooling fan working?

Good thing there is a GP on a larger radiator going on now that only needs two more people
yeah the fan is working . the radiator sounds nice to but i need more performance right now. think a oil cooler would help out in the heating up since that runs in the lower engine mainly?

I dont think an oil cooler is going to help youre coolant temp to drop, Could have a plug core chanel is youre rad, Water pump could be acting up, I would recommend getting youre whole cooling system flushed, That will narrow down youre troubles. But blockage usually causes the overheating problems.
Good Luck.

When the fan comes on does the temp drop any?

if it never gets into the red u should be fine. its summer the car gets hot esp in traffic or at idle, temp goes up, fan kicks in and it should start to drop, fan turns off, and it will repeat. unless something else is happening ur fine
right around the 195 mark on the gauge is about right for a 180/185 t-stat , which is the stock temp for the t-stat
run water through a garden hose through the engine side of the radiator , that will push any debris back out the way it went in and make sure its clear and can do its job
also the radiator you have might be internally clogged , same with the heater core
the cap can be bad
also this thread isnt a perfomance issue , since this is for going faster , you want the maintenance forum
Changing the thermostat isnt going to fix that temp. It's programmed that way stock for a 195 degree thermostat. So it's gonna go up to about 210-212 degrees and turn on the cooling fan, then cool it down to around 195, and shut off. What you would need is HPTuners or something to change the temps that your fan turns on. Say maybe 200 then turn off at 185.
My GTP does this same thing with a 180* t-stat, because it's on stock PCM programming. Driving down the road it'll stay cooler.
Your car is just acting normal.

I have heard people saying this alot lately (use HPT to adjust when the fan comes on). The thing is the car was designed (not programed) to run at 195. Even lowering the cooling fan temps the car is still going to want to run at 195. This means the fan will run much long (A LOT) which over some time will kill the fan motor. Now if you dropped in a 160 degree thermostat and lower the cooling fan temps (some) it might not be to bad.

the car will never run cooler the design of the cooling system is to run at that 195 even with a diff t-stat it wont change how hot it runs thats how the design and heat dissipation is, try running the car without a t-stat in it, its gonna take forever for it to heat up but its gonna stay at around 195 all the time after its up to operating temp. id guess the only way to change the temp would be to buy the griffin rads. in the gp right now because they have more capacity and a better cooling efficiency
also lowering the fan temps with hpt is just to help the car not heat up too high, i lowered mine to turn on at 211 and off at 200 whereas the stock pcm would turn on at 223 and off at 218, itd be a bad idea to set it way low to try and go below 195 the fan would be consistently on and wear out as stated a few posts above
