To go Along with the Farewell, pics...

Ok, well I'm glad I posted the picture of the interior because I had no idea whether or not I needed to get an updated navigation system. How can I tell what system I have installed on this 540i? I'll check out that link you put, thanks LeMans.

I'll search and see if it's the original radiator and expansion tank. But just for my own personal info, what is an expansion tank?

At least I'll have a fun little project for the next few weeks or so, a lot and a lot of cleaning to do on the engine...

Expansion tank is circled. Either the radiator or the expansion tank will fail between 60-75k miles.

Yes, replace the radiator once you pass 75k miles since they're guarenteed to go south around 90k as mentioned before.

I have a 740iL with the same engine. First radiator went at 71k. I replaced the radiator and expansion tank then. This past Friday, just after I passed 145k, the expansion tank blew out. I wouldn't wait until 75k. If the car is over 65k with the original cooling system, replace it. If you don't plan on keeping the car past 120k miles or so, go ahead and replace them with OEM parts. If you want to keep it past that, it may be better to go with the Zionsville setup.
