GM has issued special coverage for certain 2021 Chevy Camaro units affected by a condition that may cause the engine coolant thermostat to switch on at an incorrectly low temperature.
The Special Coverage bulletin, number N242484760, applies to all 2021 Chevy Camaro units affected by the noted problem, but only as relates to that specific issue and no other problems.
The engine coolant thermostat switching on at too low a temperature can cause several possible results. The Check Engine Light on the Chevy Camaro unit’s dash will illuminate and a diagnostic trouble code (DTC) will be set. Additionally, the engine cooling fans of the Camaro may continue to run briefly after the vehicle has been shut off.
The fix that GM dealership service technicians are to apply is to replace the engine coolant thermostat completely. Among the parts needed are the thermostat and its housing, the water outlet seal, several other seals, and engine coolant. The parts shouldn’t be ordered as shelf stock because of limited supply.
The fix is applied to affected 2021 Chevy Camaro units free of charge regardless of current ownership. If the repair has already been applied, the owner can apply for reimbursement of the cost.
The Special Coverage period in the bulletin extends the availability of the free of charge fix for the engine coolant thermostat issue to 15 years or 150,000 miles, whichever comes first.
As a reminder, the 2021 Chevy Camaro was motivated by four different available powerplants, including the turbocharged 2.0L I4 LTG gasoline engine developing 275 horsepower and 295 pound-feet of torque, the naturally aspirated 3.6L V6 LGX gasoline engine rated at 335 horsepower and 284 pound-feet of torque, the naturally aspirated 6.2L V8 LT1 gasoline engine providing 455 horsepower and 455 pound-feet of torque, and the supercharged 6.2L V8 LT4 gasoline engine cranking out 650 horsepower and 650 pound-feet of torque.
The Chevy Camaro was underpinned by the GM Alpha platform, while production of the vehicle took place at the GM Lansing Grand River factory in Michigan.

Is this for the LGX V6? Same issue with several other GM models with that V6.
I have a 2023 GM V6 Van it’s problem is it takes forever to warm up. I blamed the thermostat but I think its the coolant mixture. Added some richer coolant and it got a little better. Any thoughts out there would be appreciated.
