I appreciate the video! I just picked one up and the owner said it was leaking from back in this area.

Hey guys, my 2001 330i BMW just started to leak coolant from the same hoses at 354k miles, yup 354k on it. Do you guys have the name of the hoses so I can get them and fix mine? Thank you for the video, it’s awesome and easy to follow.

The L-shaped pipe at the bottom of our radiator broke. It connects to the bottom left of the radiator (driver side) where it connect to what appears to be a large o-ring but I've no idea how to remove it. Do I just give a hard twist?

Thank god it scared me thought it was my head 😅

What pipe is it I got the exact problem on exact car

Hi, in 2008 bmw x3 i see tge same steam coming out but the temp gauage is normal and not rising, i dont see any temperature gauge pin moving towards red, also the radiator fan doesnt turn on while steam is coming, tried with bmw standard bleed procedure i dont see any coolant coming to reservoir tank, also i see the engine oil i coulnt see any milk color or coolant mixed with the engine oil nor i see any leak outside . any suggestions

on my 03 Z4 just replaced the two plastic coolant tubes, plus the water pump, thermostat, expansion tank and all hoses. Basically everything but radiator. Getting the manifold off was a bear, but I managed it.

This shouldn't apply to the e60 m54 though. So the bottom one is the water pipe and that upper one is the heater one. So I have coolant flooding out of my upper connection area, but when I pulled out the manifold there was no hose hanging out under it and there isn't anywhere for it to have gone and idk why it would have snapped there like that anyway. But it seems like my 2004 530i m54 has a "blind plug" where that upper would go in. Apparently it's only like that on e60 m54 engines and up 🤷‍♂️

I always but key in hit the start button ONE TIME with NO foot on brake. This turns everything on but the engine then turn in heater to hot blower fan speed LOW. You then press the throttle to the floor and hold for 10-12 seconds. You will hear the water pump turn on it will run for 10-12 minutes. Just keep an eye on coolant level and add as needed this is the true correct way to bleed the coolant system. It works great and has no issues when done this way. It is the true correct way it is suppose to be burped.
