How to Flush your BMW E90 Heater Core

BMW series 3 E90 heater core flush, made simple!

[@AdrianJayeOnline]

I would also do a reverse flush, very good video, underrated, liked and subscribed

Thank you so much means a lot! And thanks for the tip!

How did you manage to get the outlet hose off? The inlet comes off easy however the outlet is impossible to get off lol. Tried heating it up spraying wd40, prying it, pulling twisting for like 2 hours. There is barely any space tbh.

[@AdrianJayeOnline]

on an E90, it will be literally heat locked on, you need to do as you are doing, VERY GENTLY, other wise, cut the pipe and the put that back on (if there is any slack) but check first, rotational force is what you want, dont pull on it

Hi did this work?... i noticed that my aircon is not blowing cold either... so no heat and no cold...i assume the cold could be gas related...also can u show me jow to identify the pipes..what did u do after flushing to avoid air in the system etc

This is probably the most simplest explanation I've found on KZbin so far. I only wish the video was a start to finish example. Thank you so much for this 1 😎👍🏽

[@ClutchAndDreams]

Thank you so much for your comment, I’ll definitely remember to do start to finish on my next ones! If there is anything else you need to know I’ll see if I can help you just let me know! Thank you

I'm actually going to do this procedure on the weekend so wish me luck 😁. After watching this video it's given me the confidence to go ahead and do mine before the cold sets in as only 1 side of my heating is working. As I said earlier well done for the video and explanation, keep up the good work as plenty of people are going for DIY now a days. If you have any knowledge to share regarding diagnistic tools and coding (as that's what I've been getting into) would be much appreciated 😎👍🏽 (bmw tools, ista or inpa)

Hello, thanks for the video! Did it help? I seem to have same problem on my E90 😢

[@ClutchAndDreams]

Yes fixed my issue thankfully! Hope it manages to help you with yours!

[@ondrejpetrov]

Than you very much for your answer!! I will let you know afterwards! 🖤

[@ClutchAndDreams]

Yes please do! I have a few more videos on coolant leaks etc aswell if that helps, as there’s a few common and hard to find ones! Good luck!

[@ondrejpetrov]

Thanks, much appreciated!!

I am not clear exactly what pipes you disconnected. It would have been better if you had showed them clearly, in position, before disconnecting. ny chance of an update to this video?

[@ClutchAndDreams]

Hi Malcom! I can most definitely show you what pipes I’ve disconnected… tomorrow first thing in the morning I’ll do a part2 and put the link in the description so keep an eye out

@@ClutchAndDreamswaiting on this 😊

[@ninoxhd7863]

I’ve got the same problem would be great if you can show exactly what pipe

[@hasstan9753]

Do you have to flush your coolant first to do this?

[@AdrianJayeOnline]

no

Its fairly useless, there is a funnel in the inlet which plays a role of partial checkvalve. If you run the flow in reverse direction the debris will get trapped between the funnel and the inlet wall. As soon as you send the flow in the forward direction the debris will all get released back.
