I want to thank you for this video. I just went through massive cooling issues on my N51. First the expansion hose cracked and while the mechanic was removing it, the nipple on the upper hose broke. Replaced both. After about five days of driving, the radiator cracked near the upper hose. Replaced the N51 radiator. Car is 15 and 1/2 years old with only 94k miles. Dealer would not do any goodwill on the sulev warranty which expired seven months ago Thanks for your great videos

You’ve been a great help for my 328i, I bought a manual coupe with 109k on the n51. Got it running perfect thanks to you. I could honestly sell it right now and make double what I paid.

Man, can't thank you enough! I had a leak on my 328i SULEV and before watching this I had no idea that radiator could be covered under BMW warranty. It was! You saved me a lot of $$$. THANK YOU!

Awesome info, thanks Tim!
1K+ repairs per annum…Impressive!

Great information. All the other videos never stated that this leak might be covered. Big time money saver

Appreciate this video, found exactly the leak in 5 minutes bc of ur video thank you so much

Very helpful to avoid the worst problem with the N52 - coolant system failures.

[datkiddjophat]

I just spotted coolant dripping on my 328i to the bottom so your video help to search where Thank you 🙏🏾

[rhollyday]

LOL! My 2008 E90 has a rad leak at the exact spot on top that you pointed at. I am surprised the plastic rad lasted 185k miles. I will be replacing it and the tank myself with help of your rad replace vid. And I already replaced the mickey mouse fitting with metal on mine and two others. Thanks!

Thanks man, I've just got a coolant leak on my UK E60 (N52, 523i) and it's on the left side, so you've made my life a lot easier! Mission on 🧑‍🔧

[acgus]

Excellent video helped me diagnose my leak on my N51 328i

Great video man ! I also wanna say thank you so much for answering my DM for help .. I got the bolt off and getting the job done ! Thank you again so much ! You are the man !

[tommcbride]

What a great video! I live in NC and I thought I had the N52 going on 5 years now, but it turns out the car came from NJ and is indeed N51 SULEV. These are a pain to work on, especially on your back, I can't imagine doing it on the side of the road!

best & most useful channel on youtube!!

Great review. Appreciate the n52 content.

[majedagha]

I hit jackpot, had all these 10 issues

[markfothebeast]

Awesome. So that expensive BMW oil is designed to deteriorate the coolant hose below the oil housing so all hell breaks loose?

[mbperfection]

this question might not be related, but its also part of the cooling system. Where is the heating heat exchanger sensor?

[Michael-Ferdinand]

I hope one of these problem is the problem I’m dealing with I had the car evaluated at the dealer and they told me it has swollen coolant hoses and a leak but they didn’t tell me where and I was never able to find any leaks Ik I have a oil leak so I’m gonna check where the oil is falling and see if any of the hoses are bad I will update my comment if I find anything or not
