Originally this car had R12 refrigerant. It may have since been updated to accept R134a. The coolant/radiator system is not part of the air conditioning system. But the hot antifreeze-coolant is used for the heating system...
dexcool its the orange colored coolant
Not likely. It does however have a cooler for the transmission fluid built into the radiator. Take a look and see.
The radiator drain plug on a 2001 Buick Park Avenue is located at the bottom of the radiator, typically on the driver's side. It may be a small plastic or metal screw that you can turn counterclockwise to drain the coolant. Make sure to have a container underneath to catch the fluid and allow the engine to cool before attempting to drain the radiator.
To change the radiator in a 1999 Buick Park Avenue, first disconnect the negative battery cable and drain the coolant by removing the drain plug at the bottom of the radiator. Next, remove the upper and lower radiator hoses, along with any mounting brackets or bolts securing the radiator in place. Carefully lift out the old radiator and replace it with the new one, reconnecting the hoses and any brackets. Finally, refill the cooling system with coolant and reconnect the battery.
a leak
It uses a vacume
Just keep the coolant level up and it should take care of itself. If you have run out of coolant, find out why. After you have repaired the problem, fill the radiator as best you can, fill the coolant reservoir to the full line then watch the reservoir. If the level drops, add more before you start the engine. The coolant system will purge itself of any air if there are no leaks.
