2006 Buick LaCrosse Q&A

2006 Buick LaCrosse Question: My Lacrosse randomly over heats. The thermostat, head gaskets, fans, are fine

No coolant leaking. What else could it be? Where is the Engine Coolant Temperature Sensor located? -
Answer 1
Is the check engine light on? -
Answer 2
in the area of the thermostat. it is a 2 wire sensor. from your description, I would change the thermostat, flush the system and make sure there is no coolant in the oil. Roy -
