944 has these holes in the rear area. Should they be plugged?

 

Those holes should have rubber plugs that are spaced off of the body to allow water out but keep dirt from coming in. Most 944s lost them years ago.

 

I ended up pulling those plugs out because dirt does accumulate between the small space that is for allowing the draining of water and it will become blocked solid and the rear well fills with water.

Water does drain out those rear wells from somewhere.

 

So I'm pretty new to the 944 scene. Was pulling into the garage one day and heard "sloshing". "What the heck?" says I. Got to looking around and discovered both of the storage areas on either side of the back of the car were full, and I mean full, of water. Took a look underneath to find that the PO had actually firmly corked all of these drainage holes. Backed her out of the garage into the driveway and pulled the corks. Drivers side emptied out nicely with no signs of rust or corrosion. Passenger side drained to reveal a completely water logged Porsche air compressor and tool set.

Have since talked myself out of going back to PO to exercise a little "What-the-heck-were-you-thinking?!" therapy...

 

No ,those holes should not be plugged.One hole is for the sunroof drain tube and the other for the latch drain tube of the rear hatch.Both tubes should go through the holes and end up outside.I will take some pictures for you tonight.

 

Pics would be great!!

 

+1

the one under the tire i believe has a plug but i run without them because my taillights leak a little

 

Ok,i was wrong ,forget what i said before.Aparentely the drain tubes have diferent holes so the other two holes in the wheel wels are extra,they must have seen into the future that the hatch seal will eventualy fail and leak.Anyway it appears that they are also plugged,they have a rubber plug that is inserted from the outside,maybe to keep dust out.The part number for the plug is 111 801 177 .I found only one on mine,could be the last one on earth took it in the house cleaned it and now is sitting in a safe place till i get new ones.

 

Does anyone know where the drain holes are at the rear of the engine bay - supposed to stop water flowing into the vents ... & onto your feet - which mine does in severe storms. Also can anyone help me unplug the drain hole under the petrol cap?
Thanks

 

if you take a look up inside the right rear wheel well you will see that hose it comes to a "T" from the sun roof and goes out through the bottom of the wheel well, just reach up, pull it down, remove it from the "T" and clear it then re install, mine was disconnected and the right rear wheel well filled with water every time I washed it, never a drop since I fixed it.

 

There are also some drains at the joint between the rear inner fender wells and the floorboard. One of these was clogged on my car (probably for many years) resulting in rust through of the fender area just ahead of the rear wheel, down low. It's not a drain hole, more of a slot.

 

Mine was plugged on two different 944's, with fine sand. Resist the temptation to use compressed air! If you have heavy plastic fishing line (like used in weed-whackers), cut a piece and worm it down the tube, dribbling water into the top of the hose as you do. Spin the plastic to "drill" the dirt, it doesn't take long to get the water to flow thru it. Keep putting the water to it until it flows fast.

 

Any pics of these locations?

 

Interesting. My drain from the fuel filler was also plugged with fine sand / dirt. In my case, it was in the metal elbow. It took about 20 minutes working with a paper clip and submersing it in water to free it up. The stuff was really packed in there like cement.

On the water going to your feet, you may have a plugged drain from the A/C evaporater. There is a little rubber elbow behind the stereo that likes to get plugged up. When that happens, the water will pool in the evaporater area until it overflows into the vents. Usually the passenger footwell or the glove compartment (via the A/C line that goes to the side of the glovebox) gets it when that happens.

 

Anyone have a part number that black drain plug doo-hickey?
