2005 Buick LeSabre Q&A
2005 Buick LeSabre Question: Engine overheating.
Noticed this week that my engine temperature was running higher than normal and then all of a sudden it was in the red. Let it cool back down for a few hours drove it and the temp rose back up to just below the red. I don't see any signs of leaks. I turned it back on and let it run, the fans don't appear to be running. Not sure if that is the problem or water pump or thermostat. Any help would be useful, Thanks. - aallshouse
If while driving above 25mph temp stays low it will be part of cooling fan circuit. If upper hose is hot and lower hose is cool it would be thermostat or pump issue. to check the pump when engine cold remove radiator cap rev engine to 2000 rpm and look for coolant drop at radiator.

The water pump may develop a coolant leak resulting in an engine overheating condition.
