Drain location and cleaning
I have a 997.2 and I am due 40,000 miles/4 year major maintenance. I have been talking to dealer service departments for estimates. One recommended cleaning the body drains and of course they are wanting an outrageous fee to perform this task. Does anyone have a diagram for a 997 that shows the drains. I have seen one for a 996 on this forum but not a 997. It seems like all you would need to do is to get some weed eater line and run it through the drain lines. Has anyone done this for preventive maintenance?

My dealer recommended this too, but the only info I've been able to find on body drains is for the cabriolet. The drains go from under the carpet between the front and rear seats and exit between the rear wheel well liner and body, you remove the rear wheel well liner and there is a plastic panel held on with 3 nuts and a drain hole behind it. They are to allow water to drain out in case the top is down and it rains etc. I have not been able to find any other info about them and not sure they are even used on a coupe.

Mine is a cab, but I believe there are drains in the front of the coupe as well. Under the frunk lid in three or 4 drains (cant remember exactly how many), that drain water from the windshield and frunk lid area. Not certain about the cab region or rear in a coupe.

I have a coupe with a sunroof. I am pretty that the car has drains both front and rear on the sunroof. From looking at the 996 figure these probably dump out like the cab drains. In the frunk was the area that I was not sure where they were located.

no need to pay anyone to perform this service. I have a 997.1 cab its pretty simpe. In the front pull the plastic cover that covers the battery off then remove the panel on either side of it. Its pretty self explanatory, once remove you will easily see 3 drains in the well one on each side and one in the middle. You can use a little compressed air to blow and debris out. Once you think they are clear simply take a sports water bottle with a built in stray and insert it into the drain, give it a shot of water an the stick your head underneath the car to ensure the water drains out.
In the rear its definitely a little tougher to see but still easy enough to do. The first time i did it i removed the rear trim panel, once removed there is a black plastic trough that directs water down to the drain. Once you know where to look you actually do it my simply lowering the top and peering down through the top mechanism, againg use a sports water bottle with a piece of tubing attached feed it down into the trough and flush the drains out, the water will spill out in front of the rear wheel

The exit point for the rear drains is under the wheel liner at front outside corner just behing the lower fender lip. Over time road crud collects in this are and blocks the drain ultimately causing back up. So, you do need to remove the wheel well liners to access and clean this area to complete the drain clenaing process. Good news is , it's a simple task with rear wheels removed and it doesn't' need to be done very often.
