Coolant DISAPPEARED! | Overheating problem fixed | 2016 Chevrolet Sonic | 

Your wrong that's not the thermostat on the left the thermostat is on the right right where you're working that electronic piece on top is the heat sensor. They came from the factory made out of plastic $150 and they tighten them too tight and they cracked I had to replace mine as soon as I bought the car. Everyone that owns a Sonic has a cracked thermostat cuz it's made out of plastic 125 to 150 for a new thermostat.

Great job!

Why's that not look like dexcool coolent?

There are aluminum replacements for this part, and the thermostat on Amazon for around $35 each.

Any suggestions about the best place to buy this part?

Those paint dots are from the factory. Maybe it means they checked the torque on those screws?

just had my water outlet fixed under warranty and 3 days later the reservoir cracked due to the increased pressure from the other problem being fixed... i just fixed that myself as it would have been like 4 days til the dealer could get me in and time is money!

Mine was doin the same thing and I replaced that same part and it still losing coolant idk what else to think of that might cause it to lose coolant

What type of coolant do you use? Because I think Day show me the wrong type

What type of coolant do you use? Because I think sold me the wrong type

What type of coolant do you use for this car cuz I think they sold me the wrong type

Man I just replaced this part on my 2013 1.4l Chevy Sonic turbo, was an easy fix and I was hopeful that it worked. After driving it for like 30 minutes, the heat stopped working and of course when I went to check, all the coolant was gone. Do you have any other suggestions as to where this leak may be occurring on the 1.4l engine?

Most cars have marks on some parts even if you buy it brand new

hard to get at those strange looking star bolts

These cars are lemons, escape while you can and get rid of it

Chevy is bad about not adding temperature gages to their Sonic cars even their newer cars in 2022. That's why I don't buy them.
