Pontiac grand prix gt 3800 dexcool leak - 2003 Pontiac Grand Prix

The dexcool isn't coming from the A/C compressor ! More then likely coming from the engine . No the A/C compressor doesn't have coolant in it , has refrigerant ! Sounds to me like your engine has a problem ! Your best bet would be to take it to a qualified repair shop !

Should be in the line going into the accumulator.

vacunn leak

DexCool. However, if you completely flush the entire coolant system clean, you can use whatever you want. GM recommends, and will only warranty the engine, DexCool as the coolant.

DexCool is only a few bucks more per gallon, and your car only hold about 2 gallons total. I just flushed my car and used Havoline brand DexCool. Just make sure whatever brand you buy, it say DexCool on it. And make sure that you either premix it to be 50/50 coolant/water, or buy the premixed stuff. Like I said, you'll need about 2 gallons of mixed 50/50 if you flushed the engine out.

Until the problem is repaired the codes will come on

it will need a fuel level sensor

Depends on what sub-model you have. If you have an SE its a 3100 3.1L Engine. If its a GT its a 3800 3.8L Engine. If its a GTP its a 3800 3.8L but with a supercharger.

Check the mass air flow sensor on the throttle body. It may need cleaning or replaced if the filament is broken.

doesnt have one ,remove the bottom hose

Those cars have big problems with the intake/intake gaskets leaking, and water pumps. When you find the leak, repair and flush with coolant other than dexcool as this is the source of most of the cooling issues on GM cars.
