Mystery Pump
« on: December 24, 2008, 11:28:28 am »
Whilst installing one of Gary Lee's Tire Carriers onto my 1991 Factory Diesel Syncro (Air snorkel on LHD driver's side) we found a mystery air pump tucked into the corner of the engine compartment that tee's into the snorkel upstream of the air filter and pumps (Gary was suggeting it was a pump) air into a tube that disappears down under the engine.

Bentley doesn't seem to have any reference to it.

Anybody know what it does?

Thanks,

Cody

Yep it's the turbo Cooling fan.  Although some say  it kicks in when the temperature gets high and others that it kicks in when the engine stops.

Not sure which at this point.

Can supply some pics if someone can tell me how to insert them into teh message.

Cheers,

Cody

Step one is to get them hosted somewhere on the internet. I use www.photobucket.com, it's free, you get a good-sized chunk of storage, and they help you out.

Step two is to get the url where the picture is stored. When you hit "reply," one of the options on your screen under the post subject box is "IMG."

If you push the IMG button, it inserts a little bit of BBcode, that looks a bit like this: [IMG].

Paste the URL next in that row, then hit the IMG button again. It'll put another bit of code in the post, that looks something like this: [/IMG*].

Note: The [/IMG*] tag above has the * added in to break the tag. If the * were left out, the boards would try to read all the characters between the opening tag and the closing tag as a URL, and throw errors.

Once you have your URL nestled between its opening and closing tags, hit post, and voila! You have a picture in a post.

Be careful of how big of pictures you post; most forums I'm part of have a limit of ~800px high and 500px wide, to keep from stretching the internet window out of whack.

Help?

Isn't it the factory turbo diesel air seperator for the air intake. I have seen pics and it does look like a pump. I beleive it works as a cyclone to make sure water doesn't get in.

As i said earlier its the turbo cooling fan [i have one on my van!] it is switched on by a switch in the cylinder head water system [on mine at 107degc] it doesnt mater if the engine is on or off!!.
