I thought the sealed systems were easier to bleed - generally I thought they did a better job of providing small hoses off of all the high points of the block directly to the coolant reservoir tank.

AND... BMW isn't the only one doing that, the Cadillac Northstars were generally a "sealed radiator" system, as well as several other GM models - They have a pressurized reservoir tank.

 

Right now I'm a gas n go kinda guy, if you know what I mean.

I only get dirty on the F4i.

 

Ford is a sealed radiator system as well, most new fords anyways especially F-Super Duty. So is prestone or motorcraft green coolant ok to use or should i just buy the Honda stuff and get ripped off? Honda automotive coolant the same or it has to be motorcycle honda coolant? I plan on flushing almost all my fluids before i ride next season, give her a fresh start.

And yes the hose does look over tightened and leaking and a new cap wont hurt either

 

Generally the "sealed" systems are easier to bleed. BMW's are just extremely touchy in that if you don't get them completely bled and there is an air pocket it will overheat in a matter of minutes. Also if the weep hole in top of the expansion tank isn't "weeping" there can also be a problem. They are just very touchy cars, but I do love working on them. Pays my bills and then some.
