Re: car still runs hot
Not sure if the Camaro's are subject to the same issue but had the same problem. temp would drop a bit after sitting at idle for a while, then heat up soon as I got on the highway. turned out to be an airdam under the rad was pretty screwed up, replaced it and all is good.

Re: car still runs hot
Yes, the air dam is a must,these are "bottom Feeders." But some people don't know that these cars in stock form run a bit hot. I've even seen where they say, "My car reached 220* it's running hot." 220* TO 230* is not running hot.

Re: car still runs hot
220 is operating temp...when it starts to near 240 is when you pull over and let it cycle...

have you checked your thermostat to see if its stuck closed and not cycling coolant?

is it the original radiator? after so long they become rusted and build up gunk, which can hinder the cooling effect in the coils...

also, are you using straight coolant or a diluted mixture of around 50/50 coolant to water?

just some ideas.
