To avoid unsightly marring, carefully pry it off. You'll need to do this on both the driver's side and the passenger's side wipers. ![](http://farm3.static.flickr.com/2790/4020848230_73590aa241.jpg) I used a small slotted screwdriver to pry the cap loose. ![](http://farm3.static.flickr.com/2518/4020088997_aae1e05341.jpg) When the cap is removed, a small nut is visible. ![](http://farm4.static.flickr.com/3487/4020089381_314727cf41.jpg) Remove the nut from the wiper spindle assembly with a 13mm socket and racket handle. ![](http://farm3.static.flickr.com/2765/4020090809_21cc948dd6.jpg) 13mm! ![](http://farm3.static.flickr.com/2688/4020850160_0e9dd3868f.jpg) Before I removed the wiper arm, I used blue painter's tape to mark the location of the wiper blades for future reference. | ![](http://www.318ti.org/forum/images/buttons/collapse_tcat.gif) Tutorial Tools | | | | | | | | ![](http://farm3.static.flickr.com/2787/4020091697_4d8f11bfa2.jpg) Next, I wiggled and jiggled the wiper arm until it finally came off its spindle. I've placed the new part near the base of the windshield for comparison. ![](http://farm3.static.flickr.com/2238/4020092415_00ff3350c6.jpg) See the plastic grating covering the air plenum, just below the cowl? That needs to come off. ![](http://farm3.static.flickr.com/2774/4020092101_8ee801920a.jpg) I just gave the grating a swift jerk and it popped off. It's now temporarily resting on the radiator housing. ![](http://farm3.static.flickr.com/2459/4020093019_a178dbd2ca.jpg) Remove the old driver's side cowl piece. See the clips on the back? I removed them and put them on the new driver's side cowl piece. I couldn't figure out how to get the black clip out of its holder, so I had to pry it free. You might want to purchase new clips, but I didn't. Luckily, none of the clips broke. ![](http://farm3.static.flickr.com/2629/4020853496_15974a6f46.jpg) Since I didn't have a fine-tipped slotted screwdriver handy, I used a butter knife to remove the plastic screw caps that hold the passenger's side cowl piece in place. Once they were removed, it came right off. ![](http://farm3.static.flickr.com/2802/4020095765_5008ec70a9.jpg) Because of the way the cowl pieces overlap, you should install the passenger's side piece first. Replace those two screw caps. | Last edited by MacUser; 10-18-2009 at 01:34 AM.. Reason: clarification | | ![](http://farm3.static.flickr.com/2682/4020855930_1c6b521c66.jpg) Just position the driver's side piece and pop the clips into place. ![](http://farm3.static.flickr.com/2742/4020856302_8fc0298b34.jpg) Replace the air plenum cover. Don't forget to reinstall the wiper arms ... you'll need them later! | | | I know ... this one was simple ... too simple. Oh well, I thought someone might be interested in seeing what's involved! | | | Thanks. The only thing I would add is to test fit both sides first before fastening. | | | Quote: Originally Posted by 1996 328ti Thanks.

If I had test-fitted the parts, I would have discovered the passenger side had to go on first BEFORE I fastened down the driver side and where would the fun in THAT be? I'll always remember the passenger side goes on first because I have the remove and refit the drivers side! OK, seriously, once I had the two pieces installed, I adjusted the pieces because there was a big gap in the center and one piece was higher than the other. There was enough play in the fasteners/clips that the final alignment could be done while the pieces are still attached. Greg | | | Quote: Originally Posted by MacUser Test-fitting is for wimps!

Greg | EXACTLY what happened to me except I fastened one side and had to loosen it to bridge the gap. | | | Cool write-up man. My cowl has started to fall apart where it meets the windshield. I have been thinking of replacing them. Thanks for the write-up I think I will go buy a new set now and install them later this week. | | | were can i buy a new cowl? | | | | Last edited by cooljess76; 10-19-2009 at 02:54 AM.. | | The blue tape was a great tip. Wish I had done it. I just eyeballed the wipers back on and discovered later on they were resting too low. Every time I opened the hood, it would scrape the wiper arm. Great write up. | | | Did you reuse the 2 plastic screw caps on the passenger side? I can't find them listed on the diagram at realoem.com but I would expect them to not match the new black cowl parts. Also, 7 clips/clamps are called for, but are the grommets needed also? BTW, these are the part numbers.... 51711960843 - Covering left (1) 51711960844 - Covering right (1) 51718108613 - Clamp (7) 51138124389 - Grommet (7) | | | I reused everything I could. Surprisingly, I found the screw caps were not particularly faded, but YMMV! | | | So, the screw caps didn't come with the cowl and you re-used the old ones? If they don't match closely enough, I'm sure I can find some way to darken the caps enough to "match." I'm thinking I might order just a couple of grommets ($1.07 ea.), but go ahead and get all 7 clips ($.25 ea.). | | ![Comment](http://www.318ti.org/forum/images/buttons/comment.png) | | Currently Active Users Viewing This Tutorial: 1 (0 members and 1 guests) | | Posting Rules | You may not post new threads You may not post replies You may not post attachments You may not edit your posts HTML code is On | | | |
