Hey guys having bit of a problem , I have a 08 g37s notice one day that the temp was shooting up and I wasn’t getting same type of ac/air as normal , so replaced thermostat , bleed out system (2 times)
after I noticed car was over heating ... a week later I noticed passenger fan spinning but not driver fan , so I replace fan module... nothing chanced , I return the module and buy fan assembly, at first when installed both spin fine hi/low everything was okay ....2 days later ac compresser and fans Will turn on briefly then turn of which in return is causing car temp to gauge to rise to hot , but while I’m driving car goes back to normal temp on gauge ... I’ve also replaced relay, check all connections , no leaks or frays... any ideas ?

How is your coolant level? Have you done a coolant pressure test to check for any leaks?

=jpowersjr2 I have not preformed pressure test , I assumed problem is coolent sensor or bad ipdm not sending signal for fans to turn on and for ac compressor to not stay on also . Ran test on both open up 100 percent when car starts but after 3 seconds both disengage ( fans and ac compressor) which is when temp gauge shoots up ,
