1998 infinity i30 runs hot when ac is on. The vehicle has 108k miles and the thermostat, temp sensor was just replaced. System was also flushed. Running the heat with AC off drives the temp gauge down. Also took resistance reading of temp sensor which seems to confirm that the temp is high. Any advice next (water pump etc)? Thanks

:welcome: to NICO John!

Are your cooling fans operating correctly? Do you know if the radiator has been flushed regularly and if it's flowing well?

You might want to browse through your factory service manual available at www.nicoclub.com/FSM/ for some ideas as well.
