So I have a 2001 Honda Accord EX and it has been overheating so i replaced the fan relay, thermostat and now I replaced the radiator...still overheating. The fans come on when I turn on the AC and then it seems to run fine for a while but then when I get into traffic it strts overheating again...any ideas?

 

Fans may not be coming on w/o AC causing overheating. If so, thermoswitch A is likely reason. Should be on thermostat housing. Jump connector pins and see if fans come on w/ keyswitch On.

Car should not overheat w/ AC on. Is that happening?

Turning on heater to full heat/max fan speed will help cool engine as will turning off AC.

good luck
