I have a 2008 Pontiac solstice GXP with the 2.0L turbocharged engine. The display is telling me that the coolant is at 240ish but if I read the temperature of the thermostat housing it’s at 174-182ish I’ve changed the thermostat and then burped the system twice. Also the heater will blow hot air for a minute when I first start the car but then it will blow cold air
What makes this problem better or worse?

Hello, I'm Dusty, and I'm part of RepairPal's Car Genius team!:
The temperature displayed as 240°F certainly doesn't align with the 174-182°F reading from the thermostat housing, which could indicate a faulty coolant temperature sensor or wiring issue, leading to inaccurate readings.
Retrieving any diagnostic trouble codes from the vehicle could potentially support your evaluation.
A partially blocked heater core could restrict coolant flow, resulting in brief hot air before turning cold due to insufficient flow.
If this is beyond your comfort level, consult a trusted professional, they can conduct a comprehensive inspection and accurately diagnose the root cause, ensuring your Solstice runs smoothly and efficiently.
