I started losing coolant a week or so ago. It wasn't much, so it didn't worry me much. Today after lunch, I popped the hood and there at the top of the radiator was a small hose pissing on the front of the engine. When I got it home today, I took a closer look and it is the return line going back to the reservoir. I have looked at getBMWparts.com to see if I could identify the part, but I haven't had any luck so far. It looks like it has three parts, two on either end that are thicker and then the part running what looks to be the length of the radiator that is thinner. It is clamped to the thicker ends, so it looks like it is one part.

Where is a good place to get part information and source the part?

Thanks,
John

 

Try RealOEM.com.

They have diagrams of all the e60 systems (fuel, coolant etc.) with the corresponding part number.

 

From ur profile, ur from TX

there are alot of sites. google bmw parts. i'm sure you will find what you need

 

Realoem.com

For example:


It looks 12, the vent pipe, could be the pisser in question.

 

Thanks! That looks like a great source. I have some other parts I want to look for also.


It's item #10, but close. Thanks everyone.

 

very common. good find.

 

Found the part numbers and picked up the part from a local dealer who was good enough to give me distro pricing. Now time to get my hands dirty!

 

Which local dealer give you the good pricing?
BMW of Dallas or Classic. Any contact name? I'm going tru him next time

 

Worked with Classic BMW in Plano. Parts guys have been great so far.
