2011 Camaro overheating?

[@camillezeno4927]

My 2011 V6 Camaro just went through yet another lengthy diagnostic. Just yesterday it was saying "Engine Overheated - Idle Engine" and the temp gauge was redlining and the car goes in to limp mode. But then I turned on the heater and the gauge immediately went to half way briefly before getting "Overheated" again. I've had the thermostat and water pump replaced twice, and all hoses were also replaced and all air removed from the system. It runs fine for a about 6 or so months, then the same overheating problem. Last time they replaced the old radiator cap because the rubber was bad. Worked great for about a year, until this week. So last week I had my oil changed and fluids checked. Tuesday it started overheating again! My Mechanic checked everything out for me, and of course the problem didn't happen while he had it! WTH????? At least I took photos & video so they know I'm not crazy. They can't figure it out either. They did recommend not using the motor cover, especially during the summer. This is so frustrating. But I'm grateful it's not the head gasket! If anyone comes up with any answers, please let us know.

[@Btarkingtondec]

are your electric fans working?

[@camillezeno4927]

@@Btarkingtondec Yes, the fans kick on. I was doing fine for about 8 months, and it started happening again a couple weeks ago.

[@camillezeno4927]

@@Questhompson My Mechanic can't figure it out either. Last year we replaced the Engine Coolant Temperature Sensor and that seemed to do the trick, until about a week ago it started happening again. My temp gage will read hot, the screen starts dinging and telling me the car is hot and it goes into "limp mode". But then I turned off the car, and 10 minutes later when I started it back up the temp read fine! So I know the car isn't actually overheating, because it wouldn't have cooled down that fast. I'm starting to think there's a problem with the computer/software and that's what my Mechanic is looking into. Problem is, when I do get it to his shop, of course the car acts fine. I'm so frustrated! UPDATE: Got new fuel pump(s) at the gas tank. Bought a Code Reader, and it had a P0008 in the memory, which is the timing chain. But Mechanic said not applicable at this time. It's hot as heck in this desert right now and car is running fine. I'm crossing my fingers. I really like this car, and this isn't a good time to be buying a new one.

[@Btarkingtondec]

@@camillezeno4927 The dealer replaced my thermostat housing and that fixed it

[@ghos6t]

This is an old video but i know a lot of ppl probably still have this issue, they told me it was a head gasket because of how hot the car was getting, bubbling and overflowing and everything, turned out the coolant cap was pushing the pressure and coolant to the overflow tank but not suckin it back up when cold, if you have the same problem then change the cap and keep an eye on the level of coolant in the overflow tank, make sure there is no cracks in the bypass hose!

[@RetrogradeBeats]

You know what, THANK YOU

[@frankcanora5900]

It's probably an air pocket caught in the cooling system. It needs to be purged or evacuated. If you had repairs that included any cooling system parts like a radiator, thermostat or water pump they may not have purged the system correctly.

[@kevinbrady75]

that's not over heating but i found out a trick if you turn on your A/C it will automatically kick on your fans and the coolant cools down within 5 mins back down to 190-192

[@Humble_Lyfe]

That's what I do. My Camaro coolant goes around 220 after hauling ass on it. Turn on a/c. Lowers it down around 203-210. I think it's normal. Notttt until you see the actual temperature guage lining up on the middle and going pass the half line mark. Gets closer to H. Houston. We have a problem. I just had some type liquid coming our by the front axle on driver side. Turn out to be the upper radiator hose next to the stock intake. Water dripping out the hose. Making it's way down the hose before hitting the "T" pipe. Drips exactly on the frame in front I clearly damage the upper radiator hose because do you see how much space is between the radiator hose and the stock intake . it's widely risky to always mess up the radiator hose if you don't know how to remove the stock intake.

[@tha_plumma_gang2328]

So TRUE JUST DID THIS TO MY 2010 Chevy worked like a charm

[@tsal704]

Yeah but why would gm connect the fans to a working a/c? If the a/c goes out, God forbid, then the fans wont work. Terrible design.

[@JZL15017]

I took it to a dealer and they said the ambient temp sensor is prolly bad and to trust the needle over the digital since the needle readout is from the head. That needle never goes past the normal operating point, now I'm having the engine power reduced bs and it's telling me APP sensor 1 & 2 aren't communicating correctly. Got new TB now I'm gonna have to try new gas pedal.

[@daniela.9445]

2012 camaro v6 with the annoying thermostat in the rear of the engine found out after paying a certified mechanic to change my water pump and thermostat also me changing out the temperature sensor. It was the thermostat being literally place in the housing (not properly installed with tool provided) 4hrs later without taking the intake off I got it done. No more overheating or hearing the fans as loud as I did and no more fans on after car being turned off. 💪

Was your car overheating till it shook & the engine reduced power? & if so did it fix that too?

[@camillezeno4927]

@@daniela.9445 I had my Engine Temp Sensor replaced and that worked for about a year, then starting having the same problem. Finally, car started to shake & reduced power. Had the 2 fuel pumps at the tank replaced. That seemed to fix it for now. I'm fear it's going to end up being the Timing Chain as that was the code in memory. But, we'll see. Seems that GM knows this problem and corrected it in the design under the hood in newer models. But there's no recall.

[@user-bc1kp1sl2e]

Check to see if your coolant level is sufficient through both the reservoir and the through the radiator cap when the engine is cool. Added 50/50 mixture until full and keep an eye on the water pump for any leaking coolant. Might just be the gasket. If leaking then replace it and see if it condition resolves. Change the belt while you’re at it if needed lol Also thermostats suck to replace on the V6!

[@scottschiller9883]

I know this is an old video, but what I've learned is there are 2 temp sensors. The one under your speedometer is on the head and the other is somewhere else. I fixed mine by replacing the water pump. At that point I also flushed the system as it had a lot of gunk in it.

[@JZL15017]

Scott Schiller thanks! Any advice is appreciated at this point, the car has been on the back burner until I get parts and such so now I’ll add a water pump to the list!

[@scottschiller9883]

JZL15017 the water pump is ridiculously easy. The thermostat, not so much.

[@David-zj3bp]

Hi guys, I know this video is a few years old. But today, Friday 9/28/18, I got an oil change in my white 2011 Camaro LS. The previous oil Walmart techs put in (May 2018) was Castrol Full Synthetic 5W-30 (they usually ask what brand of oil I want. But this particular tech didn't ask & I assumed they would used Mobil1). That was the first time(to my knowledge, I'm the 2nd owner) Castrol has been used in the engine. Today I specifically asked for Mobil1 Full Synthetic 5W-30 with a high end ($14) Fram oil filter. Before I got the oil change the engine coolant temp. was showing 192-194 Fahrenheit. After the oil change it was 210, maybe got to 216-220. One would expect that the coolant temp would remain in the 190's, since it's fresh oil, but apparently not. I'll keep monitoring it to see if it stabilizes. I have a strong feeling this is due to the switch from Castrol back to Mobil1, both are full synthetic. Maybe the new oil is cleaning the remnants of the previous oil.

[@JZL15017]

David C. The brand of oil will not affect temps that much, make sure they put the proper amount of oil in, if you’ve been doing a bit of “spirited” driving then those temps are normal. Just cruising, nah. Check thermostat, water pump, coolant levels, etc.

@@markoprusevic9175 LOL, they use Mobil1 5W-30 full synthetic oil & Fram oil filters. They charged me around $55 total last time for 6 quarts & oil filter, labor, taxes.

@@JZL15017 Wow, it's been two years already. I ordered a Duralast radiator, A/C Delco water pump, thermostat housing w/new thermostat. New radiator hoses and Continental brand accessory belt.

It’s normally if the water is stopped inside hot engine the water be hot too and the cooling sensor reading just what happened inside soo if you starting up and give it some gas the cool water goes inside the engine...... that’s all about

[@JZL15017]

Still not fixed, but, I did find the source of the problem I think. My wiring harness had been severed in my accident and I found said wires wrapped together with electrical tape.....such a great repair job T_T

[@JZL15017]

If there is an exposed wire somewhere that water can get into that's prolly the culprit, this happens main,y when it rains or I wash the car.

[@JZL15017]

No actual resolution to the problem, have a feeling there might be a short somewhere as well as a few other things... Been fighting this other dealer because I'm out of warranty now but was told if my vehicle had been in before warranty expires it would be covered, well I'm thinking a few things now, Water pump is bad, or a temperature sensor is bad. It tells me it's 115F outside when it's only 95F. Besides this issue the same dealer ended up costing GM a new engine for my car because the service tech didn't put enough oil, car started knocking and I tried to let them hear it they weren't able to "replicate the knocking sound" that I could hear plain as day. Week later the engine locked up.

[@dylanburnett2459]

It looks like the car is turned off, therefore the water/coolant is not circulating through the radiator, so obviously it's gona get hotter just sitting.

[@JZL15017]

Dylan Burnett if that's the case then why did it start after my vehicle was repaired? No car I've driven sits there and gets close to 300 like that after being turned off, the car is also in auxiliary so the fans should have come on, I don't need useless comments like this that don't help.
