leaking antifreeze but not hoses, water pump, or radiator.....could it be the a/c condensor?

Asked by Oct 30, 2012 at 06:37 AM about the 1996 Buick Park Avenue FWD

Question type: Maintenance & Repair

I have checked the hoses, the water pump and the radiator for leaks and found nothing.  The a/c condensor is wet on one end.  Could that be my leak?

No.The A/C condenser drain is plain water not coolant. When you see a puddle after parking when running the A/C check to see if it is water, or coolant, it's easy to tell stick your finger on the puddle and if it is slick, oily, it's not the A/C... Freeze plug maybe, heater hose, many things that are hard to trace

Re-check your radiator if the antifreeze is by your A/C condenser it more than likely the radiator.


The key is to figure out HOW and WHERE you are losing antifreeze. Don't guess. A new radiator might not be the real cause. Is coolant seen on the ground? Does the coolant level mysteriously "disappear" from the radiator? If it is not an obvious leak, rent or borrow a cooling system pressure tester. Attach it to the radiator and pump it up to about 15 psi. If you have a leak, it WILL start to drip. Sometimes it takes a few minutes. If you find no leak, you may have a crack in a cylinder head, or a leaking head gasket. Does the exhaust have a lot of white smoke even after it is warmed up? If so, this could be coolant being burned in the cylinders. Finally, are you sure the wet A/C condenser is coolant or is it just an oily damp spot from a leaking A/C system? Just because it is wet does not mean it is coolant. It could be as simple as a worn out radiator cap. Let me know what you discover.
