- In this video I will replace coolant reservoir on a 328i E90 with the N51 SULEV engine. This will be the same procedure for the E91, E92 and E93. Even if its has the N52K engine.
Parts:
17-13-7-640-514 Coolant Reservoir
17-11-7-639-020 Coolant Reservoir Cap
82-14-1-467-704 Gallon of BMW OEM coolant
Tools:
3/8" ratchet: amzn.to/3h9zshn
- I recommend getting a ratchet with a flex head. This provides ease of movement and more flexibility,
especially when used with other jobs
3/8" extension set: amzn.to/3Fxtnoq
10mm Socket 3/8": amzn.to/436Yu45
or
10mm Socket 3/8" Deep Magnetic: amzn.to/43NF9VS
Craftsman Pick set: amzn.to/3W0etwl
Pocket Screw Driver : amzn.to/3HkKHym
- This is a combo kit comes with a small Philips screwdriver. We will only need the flathead but this is the best value for the price
Flat head screw driver: amzn.to/3iJpp32

Muy buen tutorial muchas gracias 😊
Thank you so much!
👍🏼
Ty lol just did this step by step
Nice how did it turn out?
how did it turn out?
What if do this the after u get a engine malfunction making your bmw run slow?
It could be the coolant level sensor is maybe unplugged or if the coolant reservoir is not genuine it could be a problem with the new reservoir level sensor. If possible scan the car and check what the code is
It’s a n51 fyi
Thank you 👍🏼
Hi there! I replaced the tank and the only issue is that there is a small leak coming from the bottom hose now. How to I fix that? Should I get a new lower coolant hose replacement?
Yes you should also replace the lower hose. This would be the only reliable repair. Let me know if you need additional help. 👍🏼
Thank you! So far, I’ve replaced the valve cover gasket, window washer fluid filler hose, spark plugs, ignition coils, coolant reservoir, and cabin filter. This vehicle is much easier to work on than a Ford. But, I’m curious if there is a troubleshooting book out there? Versus me taking it to BMW. Since they wanted 13k to fix it, I’ve done most of it for much less. I’m wanting to know a better way to test all the sensors? A voltmeter maybe?
That’s awesome! Doing your own work would greatly reduce the cost of ownership. The repairs on your BMW are not hard to do either. I think it’s just having the confidence or seeing someone do it.
A simple volt meter can give you good readings quick. But to test can bus signals you would need a much better meter a fluke 88 or 89 would be able you capture fast can bus signals. There are great videos on RUclips that can help you understand how to use those meters as they are a bit confusing. This meter is not necessary unless you do run into can bus issues. So I wouldn’t invest in this just yet. I would stick to a much less expensive volt meter.
A simple code reader would be good to have as well. Again you can get real fancy here but for the most part is not necessary. If your budget allows even some 100.00 scanners nowadays give a lot of good information such as current freeze frame data and live voltage readings on certain sensors.
What other repairs do you need to do on your car?
@@friendlymechanic9778 I just wanted to say, that I went back in and replaced the water pump and thermostat, and tightened all the hose clamps and now she runs like a champ! Thanks for all your videos!
Thanks for the update glad everything is running good! 👍🏼
Hey! I was gonna do this job this week and was wondering if the lower hose on the expansion tank needs a new o ring replacement?
No it’s usually okay without replacing the o ring. I can’t find a part number for that o ring either.
@@friendlymechanic9778Is the O ring located where the coolant exits the reservoir at the bottom, if so is it the clamp at the end of the hose? mine has a crack in it and im wondering if i’d be fine putting duct tape on it temporary?
No coolant will continue to leak if you put duct tape.
The o ring is inside the coolant hose, but that wouldn’t fix the issue if you see a crack on the outside.
@@friendlymechanic9778 i wish i could show a picture of its its like a extended clamp at the bottom of the reservoir and it has a little crack i was wondering if i could un attach it from the hose and put a old one
How do you replace that red gauge that pops up out of the coolant showing the leve? My sons came out when I lifted it to see how high it would go, but coolant was low, so it didn't like it when the float came out of coolant, I actually think it broke what was holding it on as I used needle nose pliers to push it back on, but it is soo brittle it broke one little piece off, which leads me to believe what ever plugged into the float to attach the level/meter broke due to the brittle issue. I'm over splaining but my son just bought his first car w/ his own loot and I feel bad I broke it, well hehe I don't think I broke it but if you own a car and don't think things are going to break, I got newz for ya. Anywho, this video is incredible, subbed, commented, obviously, liked and shared, if you can maybe point me to a video that shows that Id really appreciate it. Awesome content A+++ in my book.
Thank you for the support I greatly appreciate it. And don’t worry the more info you give a mechanic the better and faster he can fix your issue. As for the float issue. It would be best to replace the entire coolant reservoir and cap. There is no sufficient repair I can provide to fix the float reliably. Luckily it’s not too hard of a job and the part isn’t too expensive.
Let me know if I can help further.
Can I use a running car for entra battery? Please help as I’m going down this tomorrow. Thanks
I’m sorry I don’t understand, can you clarify?
@@friendlymechanic9778 I mean if I can do the bleeding process with jumper on another running car instead of a battery charger
Oh I see using another vehicle as the battery charger. I have never used that method because I always use a charger but I don’t see why it wouldn’t work. Just don’t turn on the car while it’s bleeding.
@@friendlymechanic9778ok thanks
Is there any other way to check if the sensor is broken?
Usually on these reservoirs it’s the sensor that gives out. Rarely is it the control unit.
But I would remove the connector and measure across both pins with an Ohm meter and check for continuity. If the reservoir has coolant at the full mark and there is an open circuit you have a bad coolant level switch.
@@friendlymechanic9778where u you get the pressure kit
My pressure tool was a gift from my mentor. But it is a snap on brand that he bought from the snap on truck that drives around the dealers. The adaptor I got from Matco another truck that drives around. When I get back to the shop tomorrow I’ll get the part numbers for them.
Mine is leaking in the same place. Could this be the reason for it overheating?
It can be if the coolant is running low. Not enough coolant in the system will overheat the engine.
Other possibilities could be the electric water pump or electric fan not working.
@@friendlymechanic9778 - Awesome, thank you! Is the best way for checking the water pump to let it warm up and touch the two hoses?
You can do the coolant bleeding procedure and check for coolant flow. Do this with the engine cold.
@@friendlymechanic9778 - you’re amazing, thank you so much!
Does the light have to be turned on for it to work?
The low beam light has to be switched on.
@@friendlymechanic9778 If you look at another e93 water pump operation test video, it works without turning on the low beam. And my water pump does not work whether I turn on the low beam or not. Is the water pump broken?
It’s possible. I’ve seen a few things contribute to the water pump not turning on
Either a loose ground at the ground wire for the water pump. The one held on by the E14 or E12 forget which size.
Non oem water pump
Corrosion in the connector.
Or the check engine light is on because there is a blockage internally.
Where did you get the coolant pressure test tool
My pressure tool was a gift from my mentor. But it is a snap on brand that he bought from the snap on truck that drives around the dealers.
Thank you for the reply and do you need to top the coolant all the way full to start pressurizing?
Yes you want a full coolant reservoir to do a pressure test.
@@friendlymechanic9778mine leaking from that bottom hose u put your finger on do Yk if those go bad
Yes those coolant hoses do go bad. There is a small chance that the coolant leak can be due to reservoir.
Most likely it is the coolant hose though. Not a bad idea to replace both if it is pretty old and showing signs of age.
Mine didn’t come with level sensor
How to reuse?
The level sensor can be twisted off. When you look at it you can see which way to turn it.
@@friendlymechanic9778 yea mines kinda cracked now trying to get it off not sure if it still works might just spend the 25 $ for a new one
Yeah if it’s breaking just to release it best to get a new one.
