What did you do to / for your E53 today??

Thanks Fifty150hs, I regularly drive in tight, twisty, mountainous areas, and have found a little fade at the end of long downhill sections. Just after more stopping power and longer braking before fade. Oh, and the look of those massive rotors behind the wheels

I've got slotted and have had to have them skimmed now twice because of warping/build up under heavy braking.

I've read on here that the slotted rotors seem to be more prone than solids to this so I'm giving mine the flick...

Looks like I'm having new caliper mounts made unless the 4 pot will shift everything to the correct position. Now the rears...?!?https://cloud.tapatalk.com/s/5c78d4ed...024-WA0003.mp4https://cloud.tapatalk.com/s/5c78d4fb...024-WA0002.mp4

I replaced my WP, thermostat, radiator, most of the hoses, expansion tank, radiator cap, and the serpentine belt and idlers. And changed coolant of course.



Somehow I didnt break any of the plastic parts around the radiator while working in there ... Bled coolant right on the first try ... took it for a spin in 19F weather and the car got up to full temp for the first time since summer. So my thermostat was definitely bad. The bearing noise is gone and I found that the thermostat actually had a tiny leak that's now fixed as well.



Best part ... getting up to temp will probably really help with my sludge problems. They have been showing up again since it's been so cold lately.

Getting to the proper temp will also help your fuel mileage.

I’m getting a 2EF4 “map thermostat mechanism“ code that I think is a bad thermostat. What was involved with replacing it? Hard?

It was super easy once the radiator and fan came out. I dont think I'd even try the job without removing the fan. It's easy to get to without that in the way. But you need the fan clutch wrench to get that out. I found a set on Amazon for about $20.

Pull the fan for sure. While you're in there, replace the water pump. They're not very expensive and if yours hasn't been changed in quite awhile it's probably close to letting go anyway. It'll save you pulling the fan a second time. Carefully check your hoses. If you're going to have things pulled apart now's the time to replace "iffy" hoses. Definitely get the tool for holding the water pump in place while you remove the fan. It's cheap and it will make your life easier. Also, the fan nut is opposite thread direction. The hardest part will be getting the fan back on. Good luck!
