ok here is my story I hope someone can help me.

first off my radiator took a dump. I replaced it, no problem. or so I thought. now the car runs fine, when the car is running on the hwy or even at sustained 25mph the temp stays down low. but when I get into stop and go traffic or the car sits for more than say 3 mins (after it's warmed up) the temp starts to rise really bad. it's gets to just below the red on the guage. If I run it on the hwy after that the temp goes back down after a few miles.
what gives? someone told me it might be the thermostat. I haven't gotten around to changing it, but I hope that is it.
any one else have any ideas?
thanks

Sounds like your fans are not coming on

 

Bad temp sensor, or bad fan motor.

 

both my fans are not working.
so I just need to get off my butt and fix them.

I suggest the toggle switch fan method. It takes some getting used to, but for me I feel better knowing that I don't have to worry if my fan is on or not because I turn it on before I start the car..
