First off your coolant level sensor (If you have one that is, not all Bonnevilles do) would be located on the RH side tank of the radiator (That'* passenger side) about half way down. Second, your overflow container will usually have some coolant in it when hot (Hence the 2 marks on container > "COLD" & "HOT"). The coolant'* actual level does change do to many things like: Engine temperature; inclination of vehicle (Parked on a hill); leakage and or air pocket.
