Hey guys. I just joined the forum. Glad I did. Thanks for all the great posts on the windshield washer tank problems. I'm doing it now. I have a 1979 928. It has been mentionned that removing the washer fluid tank is easy... I actually am having problems getting it out. Would any of you have any recommendations? Are there any diagrams? I have the shop manuals but they are no help!

I have already removed the wheel well cover and the additional guard. I can see the tank and have already cut the large rubber hose.

Any help would be much appreicated.

Kiteboard,
Having just done this myself, but with the fender off, see the pic for reference. At the Left end of the strap in the pic is a bolt which you can not access until the tank is removed. Disconnect the large filler hose from the tank, and remove it from the filler neck too so you don't stress the filler neck plastic wrestling the tank out. Also remove all the other hoses and wiring, being sure to note the placement of the small hoses for reassembly. With the nut at the front end of the strap removed, pull the strap off the stud and bend it pretty much straight to get the tank to pull forward.

Thanks BigAl1.
After seeing the picture, looks like I need to remove more hoses, like you suggested. Especially the one attached to the pump and remove it from the clips running vertical to the wheel well. I actually sheared the bolt off on the right side metal strap when removing the nut. Go figure. My pump is not working and I would like to get it all out and clean it from top to bottom. Also going to remove the metal inserts. I'll let you know how it goes. Thanks for the help.

BigAl1,

If interested this site could help with the rebuild. Although it looks like you know what you're doing... They are free downloadable Porsche manuals. Hope it helps.

Working on one today from a low miles 86.

Some people get them working by using a needle on the nozzles.

Not sure why that hasn't worked for me...

Great pics. Thanks Landseer. The only thing different between our cars is that black cannister. I don't have one... Looks like I'm going to have fun. I can't believe the rust those inserts create.

Thanks for the link. FYI, the pump at the bottom of the main tank is to feed the headlight nozzles in the front bumper cover. The pump for the windshield squirters is inside the engine bay, under the radiator coolant overflow tank. At least that is the way my 1980 Euro S is plumbed. See my thread about "Rebuild of my 1980 Euro S" page 7 for pics and description of this area. There is another matching pump under the small fluid tank at the RH front of the engine bay.

Lots of pumps equals many electrical connections!!!! Looks like I might have opened a can of worms. I'll check the rebuild page, should help out alot. Thanks again.

While you are in there, be sure to replace the Y connector of the lines going to the fuel vapour cannister with a steel one.

Hey guys. Finally had a weekend to myself and was able to tackle this problem. Thanks again for all the help. Some good news, bad news. The metal sleeves have already been removed by the previous owner. Bad news is... out of the (3) pumps only (1) works. Not sure whether to buy original replacement parts or go with something of newer design & better cost. Any thoughts?

Just fit one pump for the windshield and forget about the rest....who has intensive washer fluid anyway or how often do the headlights really need cleaning on the fly ??

try running the pump backward by reversing the electrical connection. That may free it up and you got nothing to loose.

jthwan22 - I did try doing that... yep, they're fried! Thanks for the tip!

Landseer

The gear pumps for the washers and the intensive washers are exactly the same.

They can be diassembled and cleaned. If you can clean one of the heads, then, if either of the motors then works, you have what you need.

The headlight cleaning pump needs to be mounted back to the base of the tank, whether you get that little centrifugal one working again or not, because it seals the bottom of the tank.

James... Good point. I'm really only trying to get this stuff done for the safety. The windshield washer pump is probably all I need. Who drives old Porsches in the rain or bad weather anyways???
