Re: LOOSING COOLANT THRU A PLASTIC PART ON TOP OF THE...
If it's where the upper rad hose connects, it's likely the thermostat housing. Some vehicles are designed with a plastic filler neck that houses the Thermostat, upper rad hose, and filler neck in one unit.

Well yes and no. The gurgling sound is air in the cooling system moving thru the heater core. The cooling system is not full of liquid coolant.
As for the cause of the coolant loss, if you fix the external leak and you continue to loose coolant, the head gasket could also be leaking.
The drain plug is actually just a screw that requires a large phillips head to remove. It is located on the passenger side at the bottom of the radiator. The best way to locate it is to find the tube that runs from the coolant reservoir to the radiator and look underneath where it hits the radiator. ------------------------------------------------------------------------------------ XPROG-M V5.0
1. Buy temp sensor and O ring. (if you are REALLY cheap I have seen
these on E-Bay motors for like $4 - my stealership wants about $9).
2. Recommended while at the dub parts counter get some g12 coolant -
just in case you loose alot - you shouldn't, but it would **** having
to drive with low coolant in your bug to go get some. (done properly
you will lose VERY little - if you are like me - see below - get the
3. On the 2.0 engine the sensor is located on the coolant line coming
from the top of the radiator and runs along the right (driver's side)
of the engine. On the driver's side of the engine this hose connects to
a "junction box" which has the sensor on top and facing the interior of
the bug (4 wires).
4. If your engine has been cool for atleast an hour, remove the clip below the sensor by pulling it towards you.
5. Remove the sensor by pulling it away from the hose.
(note: I am a ******* and let the engine sit for only ~15
minutes...coolant shot out of the hose in a big blast when I removed
the sensor - VERY VERY luckly none got in my mouth or eyes - just all
over my hands - don't be a ******* - wait ATLEAST an hour or so)
6. Seat new O-ring on new sensor and make sure it is all the way to the top of the metal part of the sensor.
7. Insert NEW sensor in hose and press firmly downward so it sits in
the hole snugly. Replace plastic clip below sensor on coolant hose.
8. Unplug 4 pin connector from old sensor and plug into new sensor - if
the pins line up you should hear a tiny click as it locks into place -
DON'T force it.
Check the exhaust while it's running. If it is coming out a whiteish smoke it could be going thru the motor and coming out the exhaust. Try pressurizing the coolant system. It should hold at a steady pressure. If not it's leaking into the motor. Sorry!
Has your check engine light turned on....and is still on? if no light is on its a leak on your radiator or as simple as the radiator drainer loose. those radiators are made of plastic and are not made to last! good luck!
Had this same problem. The plenum has a coolant port for the EGR valve which lets in a small amount of coolant. The intake plenum is plastic and will leak coolant into the lower manifold. You will need to replace the warped leaking plenum with a new one, flush the engine, Coolant DOES NOT LUBRICATE THE MOTOR!!! CHANgE OIL & FILTER.I did this myself, lots of stuff to remove & replace. Runs like new after replacing the plenum.
