Unknown part with disconnected hose

Post by s3bi » Thu Nov 21, 2019 11:22 pm

Hi,

I've found a hose which is not connected that's coming from this part:

Unfortunately the part number is worn and not readable. I also couldn't find a detailed overview of the parts in the engine bay, where it would be mentioned.
The hose ends at the right side the air filter box.

Can someone tell me what this part is and where the hose is supposed to go normally?

It's a 1996 Volvo 850, 2.5L 10V 106kW.

Thanks in advance.

It looks like one of the air box hoses that control the hot air flapper.

Look for two fittings on the rear of the air filter box and see if one is open without a hose

There are also cruise control hoses in that area, those go under the air box , I believe

It looks like the hose attached to the device in the second photo is near to failure. The hose diameter change at the end of the hose nipple is showing failure cracks. It would be good to replace now before it fails.

Soap Box Rant Alert!

Everyone attempting to service a modern vehicle should periodically check vacuum hoses for signs of failure - swelling, cracking or hardening. Replacement is cheap and often does not require tools or knowledge. Failures may leave you stalled in the road in the dark and wet. Replacing them at your convenience is better and you will learn some about the hose routing. Just be sure to replace with same size and remove only one hose at a time. You might also find some fluid leaks.
Soap Box Rant End.

Hey, nice engine ! Without that pesky turbo pipe in the road and the collectors edition “DOHC” cover.
