The other day, I noticed a small hard plastic "tube" connected to a box which I assume contains the engine computer or some other electronic part. It appeared that it should have been connected to something (more on that later) but it wasn't. It didn't seem to be attached too firmly, but I didn't think much of it.<p>A day later while driving, I hear this horrendous screeching noise coming from the engine bay. I pulled over, shut the engine off and noticed that the little tube that I was checking out the other day was missing. Assuming it might have fallen off and landed somewhere dangerous (like in the drive belt) I fished around until I found ANOTHER plastic tube, this one badly mangled and lying on a shelf near the bottom of the radiator. <p>I attached 4 pics below....anyone know what this is and how I can replace it?<p>Thanks!<br>Gordon<p><br><A HREF="http://www.esnips.com/imageable/medium/e38858b3-7535-4878-9bfb-9ada5c898b1d" TARGET="_blank">http://www.esnips.com/imageabl...98b1d</A><br><A HREF="http://www.esnips.com/imageable/medium/eea897f4-6544-4b69-9923-10b2fd281408" TARGET="_blank">http://www.esnips.com/imageabl...81408</A><br><A HREF="http://www.esnips.com/imageable/medium/197053b1-186a-4963-8e25-dc98b4487a64" TARGET="_blank">http://www.esnips.com/imageabl...87a64</A><br><A HREF="http://www.esnips.com/imageable/medium/62338c91-4e81-4d2f-acd3-d5693428a8aa" TARGET="_blank">http://www.esnips.com/imageabl...8a8aa</A>

You might want to post the pictures somewhere that doesn't require us to sign in to view them.

Re: What Is This Part??? (Dueling70s)

Good point, I didn't realize you needed a sign-in to access them.<p>Which site do most people use to post pics?

If it is what I think it is, the tube is supposed to funnel cooling air to the ECU and tranny computer.

If you are describing the engine ECU box cooling air duct, it attaches at one end to the ECU box, and at the other end on the radiator shroud, just below the fan relays.<p>I suppose if it were not secured at both ends, it could fall off...

Re: What Is This Part??? (flat_six)

VolvoMax is right. This is from Vadis...something you're not going to believe about how the ECU is cooled. Cooled air in the summer is piped fropm the A/C to the ECU. In the summer, warm air is piped there to warm it. So, It is improtant to seal up the accordian pipe from the front of the radiator to the ECU box if it's broken.

Re: What Is This Part??? (MadeInJapan)

Yep, that's it. The piece that is missing from mine is the part that exits out the front of the box and then apparently attaches (?) between the fan casing and coolant (do they mean radiator?) And what is it attached to, if anything?<p>So I can assume it is getting cooling air from the A/C but it is not properly being passed through the box since there is no vacuum on the other side to "pull" it through.<p>Next logical question: anyone know what the Volvo part # is?

Found it for your 2000 S70. It's just labeled "air duct" and is part number 8619305 and is also further explained by a number in parenthesis as (3543507). Give fcpgroton.com a call...they should be able to get it for you cheaper than the dealer.

Re: (MadeInJapan)

I had problems with mine too: it started to open in the accordian part. I tightened electric tape around it to make sure the holes would not appear anymore. I guess it got used after 8 years with all the salt, calcium, dirt on the roads.<p>BTW Groton are awesome; they really have cheap Volvo factory products. I just won't ever *ever* buy my stuff at the dealer anymore! <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/cool.gif" BORDER="0"> Just as an example, I got an auto dimmer rear view mirror for 1/3 of the dealer's price...! <IMG NAME="icon" SRC="http://********************/smile/emthup.gif" BORDER="0"> <IMG NAME="icon" SRC="http://********************/smile/emthup.gif" BORDER="0"> <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/biggrin.gif" BORDER="0">
