Coolant pipes behind E53 M62 V8 engine, Part number?
 

There are two big coolant pipes behind engine M62 V8 near fire wall beside CCV and oil separator. It supposed to be changed at time when you do the valley pan job. I have a long trip come up, I touched one of the coolant pipe and it seems to be soft and ready to burst. I like to know the part number of these hoses and also is it easy DIY?

Hope anyone can enlighten me here. Thanks.

Also, realoem.com Did not show anything behind engine at back end of valley pan.

All of the vehicle hoses are listed in BMWfans info. I believe you have to look under the cooling system to locate them. You are right that these hoses should be changed because they do become soft and then deteriorate rapidly from thereon in. I changed all of the coolant hoses when I did my timing cover seals, timing guides, chains etc. to assure that I would not have any leaks in the near future. There are lot of hoses and it just makes sense to change them all instead of trying to change one by one as they leak.

Thanks, but still have no luck to find them
