Yes they can become really stuck, if you use a pait of channel lock plyers and grasp the otter edge then push the cap down and twist at the same time should come o off I would suggest you replace the cap too as well as the antifreeze.

2000 cadillac deville is overheating, replaced thermostat: water pump radiator had head gaskets fixed it's saying check coolant level and it spews coolant from the overflow tank cap when hot thoughts?


Two cooling fans controlled by three relay's . If only one fan is working ,that could be a problem .
Coolant Level Sensor Description
The coolant level sensor monitors the coolant level in the cooling system and indicates if the coolant is low. This sensor is located at the base of the radiator surge tank and is not serviceable.
CHECK COOLANT LEVEL (2)
The IPC receives a discrete input from the engine coolant level switch. The engine coolant level switch is normally closed. When the engine coolant is low, the engine coolant level switch opens. When the IPC receives an open signal from the engine coolant level switch, the IPC displays the message on the DIC.

Relay Driven Dual Cooling Fan Diagnostics There are using a pontiac , by your cadillac is the same .
