Hi y'all! I just wanted to ask you guys if you have problems with the goat overheating in 90 degree weather and slow moving traffic. My dealer told me that it was. I can't imagine that it is. Everytime I get stuck in stop and go traffic for a couple of minutes, the gauge goes up to the red. The fans are running like crazyand if I start driving for a longer period of time, the needle comes back down. Yesterday i just stopped he goat for 2 mins and the needle was going up in the red. My dealer checked it and didn't see anything wrong. They said that this was normal, but it gets annoying over time. I am scared to go downtown bc I don't want my engine to get hot... So is my dealer right?
Overheating is NEVER normal no matter what the ambient temperature is. The thermostat, coolant temp sensor and fans are in place to control temperature in a NORMAL operating range. If the temp gauge goes into the red then something is wrong. Even a faulty radiator cap can cause cooling problems if the spring within it becomes weak and cannot prevent antifreeze from releasing into the overflow tank. That would be the first thing I would change since it's inexpensive. Point blank, the dealership is full of sh!t.
DO NOT be alarmed if you see "gunk" on your dip stick. If your dealer further investigates and sees this and tries to feed you a line that that is the cause don't buy it. That gunk is a sealant/rust inhibitor that is put in at factory. IF they end up flushing your system out have them replace the "gunk."
Based on your dealer's inept theory that it is normal for your car to overheat during routine driving, be leery of other lines of $hit he may try and feed you. Shop around for a different dealer if it's possible.
Talking to a local tuner, and a buddy who is a Mechanic for a larger dealership, I've been told that a common problem to address with LS2 series engines are failing waterpumps.
I'd imagine them being dead on, as I had mine replaced at 12K, and was told by my dealer that they've had numerous pumps replaced over the course of a few weeks.... Appears to be a fairly common problem with vette's as well. Have them check the pump to ensure it's properly circulating coolant, and use this opportunity to get a lower temp thermostat.
Have you ever added coolant, "watter Wetter" or any additives? Just curious.

Over Heating is not normal. In the summer time on 90 + degree days you temp should not go above around 190. A few easy things you can check and replace are the Thermostat and radiator cap. Check your coolant level in the radiator with a cool motor and check the level in your over flow coolant tank with the engine fully warmed up. Constant high coolant temps could also be a sign of a bad water pump . Bring it to a good shop or one of our sponsers and get it checked
put a 160* t-stat, new rad cap, and check fluid levels. After that would be to make sure the fans kick on, maybe a simple relay, then water pump. I would check your oil and make sure you aren't leaking into the block. Overheating may cause gaskets to fail. If your oil looks like mud its toast.
I haven't messed with the system at all. I trusted the dealer...
Some people have been getting their cooling systems flushed because they noticed some gunk in the radiator. that GUNK was put there from the factory. It is a Anti rust agent and a coolant lube and sealant. If you replace the coolant then you need to get the gunk from the dealer and put it back in.
My cooland has a funny look to it's color due to the additives in it. Looks like gunk but it is not. I am not going to flush mine
Like everyone has said, the temperature doesn't matter. I like in Arizona, during the summer it's about 110 to 120, and I've NEVER seen an LS2 overheat just because of that, even in heavy traffic. Definetly get everything checked.
