FEH 2006, 100,000 miles.
Pulled the passenger side splash guard (5 screws) to do a new serpentine belt. Noticed these cracks.


These 2 hoses belong to the Compressor for the AC unit. These parts are noted here:

Number 2 on the diagram. Looked up this part number and it's at least $130 for the part not including the recapture and refill of AC oil. I'll post my fix (although not permanent) when I do it at the time I do my MECS pump.
This system is under pressure so cracks are never good.

 

For those wondering why I would do the Motor Electronics Colling System pump...First, it's located in the red circle.

Second, it is noted in this technical service Bulletin.

It is known to fail, normally earlier, but I'm replacing it as part of my 100k service. I'm not interested in a failure of this type while in traffic on my way to work.

 

Thanks again for the pix and info !

 

No problem. I'll post the MECS pump replacement since it does seem to be an issue that any FEH owner will encounter between 2005-2008.

 

So I got to doing a temp fix for these cracks. This is not meant to be permanent but to be a stop gap in the meantime. I've just had to dump money into a PTO, new MECS pump, new belt and all fluids and filters. The PTO was a job I couldnt do myself since I didnt heed the TSB about it before it went south. Bottom line...I don't have $130 more to buy these AC lines. So, to give me piece of mind, I'm treating them before they get worse.
Cut rubber tube into strips and cleaned both sides with brake cleaner. Then cleaned the AC hose with cleaner as well.

Both sides of the rubber were coated with Contact cement and allowed to dry. Same to the hose. I coated all mating surfaces 2 times with drying in between. Starting at the top of the hose, I then stretched the rubber strip around the hose pulling it tightly as I went.
Be sure to use the solvent based cement in the red and black can. not the "eco friendly" water based version. I was careful to overlap.



Again, its a temp fix but I do hope to delay a problem and even if one develops, like a full crack, this measure will keep things together until I can replace the assembly.
