1" Square device with electric plug attached left side of radiator. Replacement is about $50.00
The low coolant sensor in a Pontiac Grand Prix is designed to monitor the coolant level in the reservoir and alert the driver if it falls below a safe threshold. If the sensor is faulty or the coolant level is indeed low, it may trigger a warning light on the dashboard. Regularly checking and maintaining the coolant level can help prevent engine overheating and damage. If you experience a persistent warning despite proper coolant levels, the sensor may need inspection or replacement.
bad sensor
perhaps you have a bad coolant level sensor?
On the side of the radiator, by the filler neck? This is the only low coolant sensor I know of. *Ditto here; There is only one for temp and another for coolant level. Each sets off a different warning light on the dash.
It is located three to six inches down on the passager side of the raditator... below the raditator cap. hope this helps...
Either do to a coolant leak or a failed coolant level sensor.
On a 1997 Pontiac Grand Prix GTP, the low coolant sensor is typically located in the coolant reservoir tank. It is usually mounted on the side of the tank and is designed to monitor the coolant level. To access it, you may need to remove the reservoir from its mounting position. Always ensure the engine is cool and the system is depressurized before attempting any maintenance.
On a 2004 Pontiac Grand Prix the oil level sensor is located on the Oil Pan directly underneath the Air Condition Compressor.
On my 2001 Pontiac Grand Prix, the coolant level sensor in the radiator near the battery would get gummed up. You can lower the coolant level in the radiator, remove the battery, and remove the sensor. Clean it and replace the coolant. I was having to do this yearly. One common problem on these Pontiacs is a leaking plastic lower intake manifold gasket set. A small amount of oil can contaminate the coolant and lead to this build up on the sensor and thus the coolant light illuminated. I changed the l.i.m. gaskets on my car with the improved all aluminum replacement gasket set. In my opinion, this is a very good engine but why GM went with these plastic gaskets is beyond me!!
The coolant level sensor in the coolant reservoir detects the coolant level is low. The coolant system must have a leak in it somewhere. Have a trusted mechanic diagnose it soon before you do damage to the engine.
The "Low Coolant Sensor" on a 1997 Pontiac Montana is located appro 6" below the radiator cap which is on the left as your facing the engine. The sensor measures the fluid level in the radiator itself and is prone to giving false alarms when it gets dirty.
