ok so heres the deal guys my 06 gto is overheating only at idle and i researched and everyone seems to be pointing towards the fans so i checked the temp as i heated up the car fans will not turn on until 228 degrees and then kicks into high at 235 but from what ive read they should kick on at 221 i checked fuses and relays and they all check out anyboduy have any other ideas. Any help is appreciated. thanks again guys

My thoughts:

Coolant temperature sensor or your low circuit could be bad/blown/challenged(if it is a separate circuit for low high?). I am unfamiliar with the specific fan wiring of GTO.

Does your gauge read lower than you would expect compared to actual temp of coolant, or does the fan just not come on low/regular when it should and the gauge seems accurate?

Has the car been tuned and possibly the "low" setting is wrong?

Do you have road kill stuck in your grille?

there is nothing stuck in the grille, and there car has not been tuned pretty much stock have longtubes catless mids and a vararam but low setting fans (221 degrees) does not come on they dont kick on until 228 then high speed at 235 and then the temp just keeps rising even with the fans on high

Where/how are you reading those temperatures?

This is what I'm wondering.

Check water level when cold it should be no more than one inch low, be sure you have bleed cooling system properly.

Tune fans to start at 180 and high at 196 degrees, get a 160 degrees thermostat.

thanks for all the input everyone did radiator cap and thermostat ended up being none of that the hose that pulls antifreeze from the resevoir was pulled out some so it wasnt pulling antifreeze into the radiator
