How do you bleed the air out of the cooling in a 1996 A4 FWD auto....
usealy there is the little plastic bleeder at the fire wall, but here is none. So how can i do it. Also does hydrolic fluid go in to the radiator as well??!! There is some other lines that go in there and look like hydrolic fluid.

One of the heater hoses (the ones by the battery) has a tiny hole in it, you loosen the clamp,
and slide it off of the barb till air can come out the hole. Also, there are 2 bleeders on the hard lines around the heads, one on the back under the tank, one on the front near the PS pump.

Old School Method
Park the car on a STEEP incline or jack up the front as far as you can (or use ramps). Take the 3 screws out of the expansion tank and lift it 4-5 inches higher than its normal mounting point. Turn the heat on full blast. Start the engine and let it idle with the cap OFF the expansion tank. When the thermostat opens it will burp out quite a bit of air. When you see coolant start to flow out of the small return line on the top of the expansion tank, rev the engine to about 2000 rpm for about a minute. Have a buddy watch the coolant and oil temp gauges to make sure you don't overheat. When all the air is out, the temp gauge should settle down to about 12 o'clock and oil temp around 200-225F.
Screw the cap on the expansion tank and put it back in its normal mounting position.
The bleed hole in the heater hose connector is the alternate method recommended in the service manual, but it is a major pain in the *** to do it that way as that connector is in a rather tight spot.
