Broken upper coolant hose

EndGameBMWM4 · 05-24-2019, 01:01 PM

What's going on beamer fam?

I just need some quick advice before I order parts. So my upper radiator hose broke while I was on my way to the gym.

From the looks of the portion of the oil housing unit, it looks like my pipe rotted. Should I replace the whole unit or not?

I added a link with some pics below.

Thanks in advance!

It's "Bimmer" fam.

Beamers are BMW motorcycles.

Just replace the hose. It may be difficult to remove from the upper radiator hose bib.

Also order the small hose that runs on top of the radiator. You will almost certainly break it during disassembly.

That's exactly what broke. but now I have another problem after fixing the upper radiator hose. So after replacing the hose, adding coolant, starting the engine, the car stumbles and there's a weird smell not too potent but a light smell that I can't explain.

So, during this fiasco, my battery dies and I assumed this was the cause of my car not starting up. I replace the battery with a brand new Duracell platinum h8 amg. I registered the battery through Carly, start the engine again.

This time the 328i struggles to start vs just stumbling and completely stopping. I let it do its thing for about 30 seconds but it was sounding like world war 3 in my engine and could tell there was combustion going on because it sounded like m80's (exaggeration) going off.

I ran a Carly diagnostic and received this code Fault Code: 002DEC
Fault Explanation: Power management, Battery Monitoring.

Does anyone have a clue or experienced this issue before? Thanks!

You should run the coolant bleeding procedure.

Not that failing to do it would explain immediate failure, but it would cause overheat after the car had time to warmup.

When the coolant hose blew, did you stop immediately or did the car die on you?
