2000 Cadillac Seville STS Q&A

2000 Cadillac Seville STS Question: Temperature gauge reading hot while engine isn't

I had this car since November of 2013 no issues, but now the temperature gauge is saying my car is running hot, so I naturally replaced thermostat, water pump, did a coolant and radiator flush, the engine isn't running as hot as the gauge says, but it keeps shutting my car off as the system says it's overheated. Help? -
Answer 1
Have the engine coolant sensor tested, and the temp sender as well. -
