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.
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.
verrrrry carefuly!!
On the intake manifold.
You can change a radiator in a 2001 Buick Park Avenue usi the instructions provided on the manual.
Bottom corner of the radiator, facing the engine, typically opposite end of the radiator from the lower radiator hose.
Type your answer here...where is my theremastat located
Lower radiator side of the engine.
Disconnect lower radiator hose if you can not find the drain valve. Drain water and antifreeze and flush it out good. Reconnect hose back up. Then add a gallon and 1/3 of anti freeze then finish with water.
