The radiator cap controls the amount of fluid to your reserve. So if it were stuck open as the engine heats it would spill into the reserve. Also any problem that would make your engine overheat could keep the cap opened longer then desired. Overheating engines with other than cooling problems could stem from blown head gaskets or piston rings.

Coolant Recovery Reservoir. There is no sensor in the coolant recovery tank on a 1998 Buick Regal.
To check the coolant level of a vehicle first see look for the overflow reservoir. There should be a coolant dipstick with a level gauge on it. Remove it from the reservoir to see the coolant level.
Normally in the coolant reservoir recovery tank. If you have the supercharged model it is located on the radiator beneath the filler cap and oil cooler lines.
If the coolant reservoir can not maintain the proper level of coolant, it is possible the engine could over heat when the level drops.
at the bottom of the coolant reservoir tank.
Reservoir light? You mean low coolant light. Low coolant level means the reservoir is low of coolant.
No , on my coolant reservoir there is a cold fill mark . When the engine is cold the coolant level is supposed to be up to the mark . When the engine is warmed up the coolant level is higher
The coolant level is set by the level in the coolant reservoir. There is a line for the level if the engine is cold and a line for if the engine is up to temperature. You should fill it to the corresponding line.
It is at the bottom front of the coolant reservoir.
The coolant level sensor in the reservoir is probably at fault.
The plastic coolant reservoir on the fender feeds directly into the coolant system. Just add coolant to the reservoir and if you have drained the coolant or otherwise emptied the system, you may need to check the level in the reservoir after running the engine, or more accurately, after the engine has cooled. Once the coolant level has stabilized, just check it periodically to make certain that the coolant level never gets too low.
