Hi, my parents just bought a 1998 Volvo S70 w/ turbo for my brother. The hose shown in the picture is cracked and I am trying to replace it without going to the dealer. The number on the hose is 3545307. Please let me know a good site I can order this part from and the actual part name. Thanks. <IMG SRC="http://home.comcast.net/~dbong/car98.JPG" BORDER="0">

Re: whats this part? (bongiovanni)

If it's the hose I am looking at, air gets ducted to the ECU for cooling. I would just slap some duct tape or electrical tape on it and be done with it but that's just me. The more important question is how did it get that way?<br>Heat? Rodents? Rubbing on something?

Re: whats this part? (bongiovanni)

I would just duct tape too but my parents would rather replace it so w/e its their money. The tube leads to a box, i popped the box open and theres two silver things that look like hard disk drives but thats probably not what they are. They say Bosch on them.

That is the hose to keep the control units cool-part# 8619305 about $20 from your dealer.

May I direct you to this thread....same hose on the C70: <A HREF="http://forums.swedespeed.com/zerothread?id=64184" TARGET="_blank">http://forums.swedespeed.com/zerothread?id=64184</A><br>Btw, in case you guys didn't know, the pink sensor up against the left (passenger's fender) is the atmospheric pressure sensor. Been a lot of these go out recently (as per folks on Brickboard and Matthewsvolvosite). It's also cheap and easily replaced by you.

Re: (MadeInJapan)

MIJ, thanks for the info on the atmospheric pressure sensor. The "barometric sensor" went on me last December (I assume the atmospheric sensor is the same thing) and from your description it sounds like I got ripped off by my local Volvo dealer for the repair. They charged me $170 for the part and $150 for labor. What do you think would have been reasonable for this repair?

Just looked it up because I was curious too....foreign car parts calls it an altitude sensor and they are about $150. But the R&R is so simple I could do it in 5 minutes tops. I assume it's the same thing as what we're talking about (Vadis shows it in the same location as the atmospheric sensor, but I couldn't find Barameteric anywhere in it). If all they did was replace it, I'd say the $170 for the part from the dealer was probably right, but labor should have cost $20-30 tops. <br>

That is definitely the tube used to cool the ECU box. No need to replace it unless you want it to look new. Tape it up or something.

The radiator heat apparently creates a vacuum...it needs to be functional.

The ECU Air Duct Hose for many different years is available at IPD USA for only $9.42 -- http://www.ipdusa.com/products/5889/8619305-ecu-air-duct-cooling-hose
I found a number of sites that had it, but under $10 is by far the best price for the OEM Volvo Part. I had the same problem and I hope by getting it fixed I don't burn out any of the on-board computers... although I am a little worried that it might be too late...
