I have a F25 2011 X3 28i and I can’t find the radiator drain plug. Did BMW
do away with the radiator drain plugs on the F models? If so, do you know
what the procedure is for replacing the coolant on the F25 models?
Hey, my question might seem a bit stupid, but should I bleed the cooling
system if I have opened the radiator cap just to check the coolant level
and then closed it again? I am not experiencing any kind of overheating or
AC abnormalities until now. (BMW e46 318i).
while doing the bleeding and adding the disteled water, i know the heat was
on high, but was the engin on as well?
I got a 98 E36 323is, how much coolant will I need?
Also when you flushed out the system with water you said you had 2 qts left
in there when you started adding the coolant. Did you flush out the water
with the drain plugs out, put the plugs back in then added the 2 qts of
water? Hope to hear back quick, thanks.
the question i have is, does the engine need to stay on from the start of
the fill to the end???
I was planing on doing it on my e36 m50b25 (95 325is 2.5L). How much
coolant will i need?
I just got my coolant flushed at the dealer and I wanted to check the color
on it to ensure it was done. It came out pretty clear. Is that due to the
water being added? I would’ve done it myself, but didn’t want risk messing
something up
How much would I need to fill if I did this on a N52 E60 525i 3.0L engine?
Just to point out on sentence ‘Normally, one time is plenty’ at 5:30.
I flush my system 4 times with destilled water until i got clean water.
Heater was set to max, and both engine block and radiator drain plug were
drained. Thermostat is the key. It remains closed until temperature is high
enough. If you don’t have patience and time to flush many times like i do,
there is better way which ensures total system flush (without old coolant
in the system).
– Warm engine until radiator fan turns on (Thermostat is opened long before
this happens but wait for it just to be sure).
– Flush cooling system from both engine block and radiator until thermostat
is opened. This step is crucial and most dangerous, because coolant is
still very hot. I recommend using gloves and extended tools for opening
drain plugs.
– If this is first flush of old coolant, additional flushing with destilled
water (again while thermostat is opened) should be plenty, and guarantees
clean cooling system.
– Now it is ready to fill with 50:50 mixture.

I be needing help with my 2005 BMW 325i Oil Cooler Thermostat For Automatic
Transmission Models and the coolant recovery tank instalation and don’t
know how to remove oil cooler thermostat tanks
muchaaas grasias por poner estos videos alluda para mucho
My car is an e46 325i. My upper rad hose is not too hot to touch but very
warm + hard. I noticed this after filling my expansion tank full. As it was
just hitting the lip of the opening where the cap goes, it continued to
very slowly rise and overflow, which lead me to put the cap on. I didn’t
notice any air bubbles as it rose. Also, my temperature gauge was dead
center at normal operating temperature as this all happened. The gauge
continues to stay normal WHILE the hose is very warm and hard. This is a
NEW hose i just replaced but i’m still worried. What could be the problem
with this, considering all these factors?
I may not own a bmw but i find your procedure very useful. I actually used
this method on several of my friend´s vehicles from a chrysler to a Nissan.
My house has very hard water and i was concerned aboout doing a traditional
garden hose flush. It never occured to me to fill with distilled water and
drain again. Saved my buddies and i allot of money as well. Distilled water
is allot cheaper than pre mixed coolant off the shelf.
i have 328xi 07 e90 do it do the same this video ? and how many gallon do i
need ? thank you
Hi Otto, have followed a few of your DIY’s and they are spot on. I am
currently experiencing a problem which is related to this DIY and I hope
you can offer some advice.
After a drive and my car cools down, I check my coolant level and I see it
has dropped to below minimum. If I loosen the bleed screw some air escapes
through it and my coolant level indicator rises back to max. If I go for
another drive and check my coolant after my car has cooled down the same
thing happens. No coolant loss and no leak obvious.
I have tried to bleed but maybe I am not bleeding properly and waiting for
the air bubbles to escape fully.
Any thoughts would be helpful
🙂
thank you for all the videos. I love them all.

How much coolant came out after you drained the block and rad?
Auto, your videos are flawless! I just wanted to let you know you’re doing
an awesome job. Great DIY’s.
I will be needing to fill my coolant soon, should I get it flush before
refill? since I’m not sure if the cooling system has been maintained at one
point. What type of coolant do you think is best to use? .
by the way you said ”bently” and not bmw repair manual
Hello. For a mini r53. How many gallons antifreeze will i need? And how
many gallons for distilled water? Also do i need to take out the front
bumpers of the mini just to drain the old coolant? Thanks in advance.
BMW coolant contains Ethylhexonic Acid which is a plastisizer. This will
destroy the rubber oring seals including the one in your water pump. If you
own an N62 motor you will eventually be plagued with the transfer pipe
failure to the tune of 15,000 dollars. Think Motul or Pentosin. Motul
Inugel Expert Ultra is 2012 approved by BMW and does not contain the
chemical. FYI…Bmw coolant is manufactured by Valvoline/Ashland in the
USA. General Motors was successfully sued in 2008 for vehicles damaged
with Ethylhexonic Acid.
Once completely full, does a small amount of fluid not need to be siphoned
back out to get a true full reading? Also, do you have a video on how to
bleed an electronic water pump with the self bleeding feature?
For the bleeding, if your E60 5-series has the M54 engine, you should have
a bleeder on the upper radiator hose. If you have the N52 or N51 engine (as
all 2006 and later models do) with the electric water pump see our blog
post on this subject. Go to our blog; blog.bavauto.com and search Bleeding
. You will see a recent post on bleeding the later model cars. For the
Evans NPG, we have an additional instruction sheet for this. Please send
email to: INFO at BAVAUTO.COM. The number is INS328.
If you do not have the system “full” you may have temperature issues. When
you check the coolant level in the reservoir, how far down is the coolant?
What model do you have?
Very informative but I have a question…is it possible to overfill the
expansion tank? Should a gap be left based on what the “bobber” is showing?
Where is the engine block drain plug on a E70 X5?
We do not currently have any radiator replacement videos. The Bentley
repair manuals will cover the radiator replacements for the various BMW or
MINI models. We do have the manuals in-stock at bavauto.com.
One last question. I recently replaced the water pump and thermostat and
housing. I ran out of coolant so I have been running straight water in it .
Now my question is after every few days or so I open the expansion tank cap
and the fluid level goes down so I have to be adding. Is this normal with
water because it can boiling ? I’ve checked for leaks and can’t find any.
No overheating issues either .
What engine do you have?
