my camaro is overheating only in traffic or if i let it idle for a while. When i am moving the temps are normal. i replaced thermostat, radiator cap,bled the system multiple times,inspected the sensors and with no avail. any help would be appeciated

 

Are your fans in working order? They are meant to kick on and cool in the engine when idling.

 

i dont think they are working to be honest but i dont know why?

 

is it a lt1?

 

If they're not working as the should, then there lies your problem. When the car is moving the air dam underneath scoops up air and pushes in through the radiator. When you're stopped in traffic or let the car idle some where, there is no airflow through the radiator. That's where the fans kick in and pull air through it to keep the engine and coolant within operating temperature. Make sure your fans are kicking on. You should be able to hear them.

 

my fans arent kicking on i switched around the relays and still nothing... any ideas?

 

this migth be the culprit http://shbox.com/1/temp_sensor1.jpg

 

when i was switching relays i heard the fan come on for about 10-15sec then shutoff, i then went to the car and the temp was stilling rising. do you guys think it could be the ECT. it says in shoebox guide that the ect when defected/not in working order. it will make the pcm tell the fans to come on at the wrong time and also have trouble starting when warm?

 

Unless it's your gauge one. There are two on our cars. One on the pump for the PCM and one on the drivers side head for the gauge. Turn the A/C on. Fans should kick on with it on

 

even if its not charged/working i dont even have the relay in for the a/c
