Overheating problems - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

Hey folks, so I'm posting here to maybe get some new direction on where to go for this overheating issue. 2010 1SS, by the way. About a week ago, I noticed that the temp gauge would climb to almost the limit, then slowly start to recede. I had no heat until then, and everything would be fine. I suspected either a bad thermostat or a failing water pump, so I changed both. All was well for about two days, and now I get the overheated engine warning and it does not go away. I recently did a cam swap on her, but I don't see how that could be causing this particular set of problems. I have changed/flushed almost every single thing I could think of, and now I just need some different ideas on where to look.

Is it just since you did the cams?

1KillerSS · 01-04-2016, 03:07 AM

Sounds like an air pocket.

irwin40 · 01-04-2016, 03:15 AM

Yeah, it started happening roughly two months post cam swap. I just did another burp of the system, topped off the coolant, etc. Hopefully this solves it.

I did a cam swap a couple weeks ago and had the same problem, and I to burp the hell out of it because their was so many air pockets, also run you're heater when while burping it.

NeedsWorkSS · 01-04-2016, 07:41 AM

Same with my 2010. No cam swap though. I had to burp the shit out of it and add 2qts of coolant. Shes sitting in the garage for the winter now though. Hopefully shes all good in the spring

irwin40 · 01-04-2016, 08:40 AM

I just thought all this was strange, since it had been a good bit of time after the cam swap. I appreciate all the input, fellas! Will be posting updates as they happen.

Scalded Dog · 01-04-2016, 09:12 AM

You said that you changed the thermostat... does the new thermostat have a different temperature rating that might require it to get really hot before it opens?

Trob85 · 01-04-2016, 09:14 AM

Yea I would assume air didn't make its way out and magically found an escape route I wouldn't be to worried about once you top off the radiator and overflow tank.

I had to burp and top off mine 2 months after my cam swap.

I am not familiar with how 5th gens get air purged properly, so someone correct me if I'm wrong here. One thing we used to do was to jack the car up at the front end, leaving the back half on the ground. Start it up, bring it to temp, and turn the heat on, topping the fluid off as needed. The air finds its way to the top and out of the system.

WoodBoss · 01-04-2016, 01:15 PM

Don't forget to turn your heat on to get some flow through there as well.

Batmanntexas · 01-04-2016, 02:30 PM

you can stick a shop-vac over the filler neck. The low pressure from the vacuum will suck the air pocket right out, no problem. I saw that on YouTube, and did it when I did my cam swap. Worked like a champ!
