Coolant Recovery Reservoir. There is no sensor in the coolant recovery tank on a 1998 Buick Regal.
It is located in the bottom of coolant bottle.
it is in the middle of the radiator resevior
Either the coolant reservoir is low on coolant or the coolant level sensor is NG.
On a 1993 buick regal it is on the side of the radiator.
Make sure it really is low on coolant by checking the coolant when engine is off. If the level is up to par, then the sensor may be bad.
