96 chevy camaro 3.8. i got a problem with the idle tempature, just peplaced the water pump and thermostat (180 degree). when driving around the cars stays at a constant 180 temp but when sitting and idling for more than 3 or 4 minutes the temp starts to climb and gets up to about 230-240 which i know is not good but thats when the fans start to kick on. the system is clean all new antifreeze, no air in the system everythings ready to go. iknow its not normal for the temp to climb that high does anybody possibly know what else could be cause this high temp at idle?

thanks

you can try changing thermostat and see if that help's or have you already?

yeah this is the second one ive tried. i actually had bought a thermostat that opened up at 192 cause thats what they told me the car called for but when i put that in the car would heat up to 192 the fluxuate back do to 180 and it would do this repeatedly, i wasnt happy with that i actually thought that it was a defective thermostat so i brought it back and i had purchased the 180 degree, i was a little more comfortable with that temp cause i originally thought that 192 was high? but anyways yeah its got a brand new thermnostate. i kinda stumped on this one, im thinkin maybe could it have somthin to do with the fan sensors, maybe their not kicking on at the right temp?

Tune the PCM to turn the fans on at a lower temp, to match your t-stat.
