This DIY How To Tutorial goes over replacing almost every single component on the E90 E91 E92 E93 Non M cooling system using the ECS Tuning Level 3 Cooling System Kit and a few other extras for this 2007 BMW 328i. We use ECS Tuning’s silicone hose upgrade as well as billet fitting on a known failure component (the mickey mouse hose). We also replace the Radiator, Water Pump, Thermostat, Coolant Recovery Hard Plastic Hose, Automatic Transmission Cooler Hoses, Metal Water Pump Inlet Pipe, Mickey Mouse Fitting Hose, and more! Everything seen in this video is linked down below, make sure the components fit your car before ordering! Heater hoses and heater core video coming soon! Thanks for watching!

Happy New Year!! Part of the reason I never uploaded this DIY is because of how hard it is to actually capture everything. I hope this tutorial helps anyone that needs to address their E9x cooling system (should be every e9x owner at this point lol). Let's try to hit some big milestones this year on YouTube, if my content has helped any of y'all please try to share it and don't forget to subscribe. Hope the best for everyone this year, lets get it!
I installed a mosselman thermostat so my car runs 30 degrees cooler than stock. even at 270kmh on the autobahn i am far below stock temps. You can also open the engine bay with M3 cowls & set the fan speed to sport for another 10degree reduction. For turbo BMWs, this is probably the best mod to benefit longevity & all engine/coolant components.
You make the best diy videos available. All the insights and tips make you stand out from the rest.
Keep up the good work!
You read. My. Mind.
Great Video Thanks and I just subscribed to see more, I love your videos. I am looking for the video or the heater core that you are talking about (can you please point me to it) , also. I have the same car and replaced almost everything except the plastic hose that connect the expansion tank with the termostat, transmission and heater. i have the hose that I was not able to disconnected from the heater side and don't want to damaged it as I didn't ordered the heater hose and the return hose from heater. My question is:
Looks like the plastic coolant recovery hose and the 2 for the heater are OK, I never use the heater because am in Florida and I think the is not to much circulation on the heater , the car is a 2010 with 135K. What you think about it ?. Thanks
Happy new year and nice job bro! Best wishes for 2023!

Good video as always! I did this same cooling system overhaul this summer. It’s definitely a job a home mechanic can do! Patience is key. and be sure to replace the hoses. The plastic is brittle. I have ‘07 328 also. Order flexible extension for hose clamps.
Hello I’ve been watching your videos for a little while and I’ve learned a lot. I have a 2010 528I that I recently service the transmission to include solenoids and seals. I am trying to find a program that is not gonna tear a hole in my pocket to reset adaptations. Can you please help thank you. And thank you for all the knowledge you provide.❤
Hey Jason, this comment is more generic if you don't mind?
Would you ever recommend going non-OEM, or is it a principle that should be maintained for All BMW models? I'm looking to change an E90 oil level sensor and the price difference between OEM and aftermarket seems unnecessary, what are your thoughts?
Great DIY brother and sister! And also great, you used a complete metal water pump, probably one from INA? Unfortunately, my 335i had the pump replaced just before I bought the car. It's a Continental again, with the plastic pump housing. Thanks for sharing. Dutch regards Nico.
I paid a shop to do the complete cooling system replacement on my 2009 E90 with 6 speed manual. The only thing not replaced was the water pump inlet pipe . Apparently the metal and rubber part of the inlet pipe (which I was told is a single order code) are not stocked by BMW Australia.
My goodness!!! Why does the E90 have so many coolant hoses??? E36 and E46 are so much easier… and sure enough, I just bought an E90…
Great video guys ! Appreciate the bmw content
More constant uploads on the e46 please!!!!
Let’s see B58TU g-chassis contents plz
Happy New Year….Great to see an upload from you. Once again a very informative video!!!!
Great video! Thanks.
Could've used this a bit ago lmao. Great guide, there isn't much info out there for many of the hoses.

Happy New Year, guys. Wishing a prosperous 2023.
