  1. Those plastic parts break really easy on BMWs.

  2. Hi,
    I'm not a mechanic but I'm handy enough that I can do this repair. I have a question- how tight are you going on that hose clamp? Normally if I'm using a hose clamp it's on something that isn't plastic so I just crank it down but that nipple is fragile… Thanks!

  3. How much would I be charged if I just take it to the mechanic ? To fix my coolant leak

  4. Great video! I was hoping you could help me out with advice on fixing my bmw if the nipple broke off?

  5. This just happened on my 528i. Anyone know what that hose is called so I can go get the part

  6. Appreciate this video definitely made replacing mines easy

  7. What type of fastener/clip do I need to use for the other end of the line (the one going to the radiator)?

  8. What do you think about the coolant on top of the expansion tank, could it be that the cap is damaged, hose or the entire tank? Please help

  9. Bravo.Super tutoring,super hand dexterity. 👍

  10. You forgot to run the electric water pump. Before starting the car

  11. Hi, I recently got a coolant leak where I saw the leakage on the ground as I was driving it. At the end of the drive, I got a coolant warning sign. When I got out of my car, I saw smoke come out of my engine bay. Do you think doing the hose repair and adding coolant will do the trick for my e92? Thanks a lot in advance. Great videos!

  12. Hopefilly I get a answer back. What is that part called that has the nipple ? I tried to replace the hose but the nipple broke on me.

  13. What's the name of the upper hose?

  14. That hose gets so brittle. Breaks with so little pressure. Cheap bmw parts.

  15. I have a 98 bmw 382i & I noticed after turning up the heat to 90F and press the circulation button it seems like it bled out the coolant system? & so now, I noticed it'll drive an hr & 30 mins without overheating then I would have to put water again in it. I will have it checked but i'm pisses because that car is my baby, can't have her parked. I didn't see any signs of any leaks but who knows..

  16. Hey I’ve watched your video, but mine is coming from the top, not the hose. It seems as if it’s leaking from the tank? It’s an 08 328i coupe any help would be appreciated, thanks

  17. I am going to buy an e90 can I please have your email I will be in need of a professional!

  18. Bro you saved my life … where do I buy this part and what do I ask to get the proper part

  19. how much would a repair shop charge to fix a coolant leak on a BMW X3 2008 (high and low end costs)

  20. my radiator stick is broken… so how high is the fluid level suppose to be in the expansion container
