Update on electric water pump bleed and a question -
So the automatic bleed procedure on my 535 was not working after I replaced the coolant expansion tank. I was not on a tender/charger - I don't even own one, so I picked one up at Autozone. Well, the thing flashed that it was charging and not maintaining so I just let it roll. I was working in the garage and about 5 hrs later it went from charge to maintain. It beeped when it switched over so I glance toward the car and almost immediately afterwards the auto bleed process kicked in!
Next is is a VCG replacement. 1. - I can't find any DIY's for a an E60 N54 - seems like they are all 3-series. And the ones I HAVE seen have not called for any RTV to be used; I thought that was odd. Is it not called for on this motor? I've done them before, but not on a car like this.
2. Anything else I should consider doing while I'm in there? My plugs have about 40K miles on them - replace? Crankcase vent? (is the RB product worth a look?). If the coils are still original is worth looking at replacing? I'm not having any mis-fires, just wondering if they are still working at optimum performance. Thanks in advance and sorry for the long post -
