I think it is in the radiator on that vehicle. I have a similar Park Avenue and replaced mine for that reason; if I remember correctly, it was just below the cap.

 

Our 2000 LeSabre used to drink coolant like crazy. Turns out there was a coolant system leak covered by a recall. It's thirst for coolant was quenched by the recall. Make sure to check with your dealer to ensure the recall work had been performed. I'd wait for the vehicle to cool down, and open the rad cap to take a look-see inside to see if there is plenty of coolant (Dex-Cool is used on these models). If coolant is not there, top it off through the radiator (with 50-50 coolant/H20) and get over to the dealer ASAP.
