can you post a video on youtube showing me what you found?
Hi, I recently saw some oil residue on the coolant reservoir and I am
planning on use this tutorial to change the coolant on my 2006 330xi. What
do you recommend?
yes
Lol ethylene glycol and ethanediol are the same compound…chemistry’s a
tricky devil when it comes to naming conventions.
not really. i dont work for bmw any more, but that doesnt stop the folks in
my new town coming to me with their issues. i’ll probably post some X3
diy’s, but there arent enough bmws to allow request taking
Thanks again for the Info about the codes for the 745I. I will try to
figure what you said about the shifter. Your talking about the gear
selector inside the car or on the actual transmission ?
Great vid. In the future, can you post a coolant flush proceedure for an
E70 X5?
yea, probably just the intercooler and air tubes. let me know how you go
doing the job
Well, here in the states, we like to keep our.ATF at something closer to
176° F. At 205° F, there is that much less thermal reserve before the ATF
reaches a temperature where it starts to decompose into varnish and loses
its lubricant properties so clutch material begins to contaminate the ATF.
wow thank you so much, this is greattttt help!!!!!!!!
How often should the coolant be replaced in an e90?
Wells hat sucks for me but at least you are nice enough to answer ?s I just
did suck and fill power steering flush and like an idiot I put ATF not
chf11s what would be the best way to do a complete flush in scared I will
mess the seals up now thanks also that is when the power steering lock
light came on the next day could that be why our just coincidence
Thanks man are you doing request again
Also these gearboxes use Shell M-1375.4 oil, not ATF. Thanks for commenting
though
I was finally able to flush the coolant on my 335XI. What I did was… Take
off the coolant res cap. Raised the car and took off the undershrouds.
Removed the intercooler cover and intercooler. From there, you can see the
rad drain plug. I drained it, filled it back up with water, and did the
bleed process (let the electric water pump do its thing). I let the car run
and let the thermostat open so I could get some more of the coolant out.
After letting it run, I drained it again and filled it.
For an e39 do you just – Open coolant cap – Drain the coolant from the
drain plug – Open bleed screw – Put new coolant in until the coolant comes
out the bleed screw – Put bleed screw and cap back – Done?? Is that the
procedure for this? Great channel btw, sucks that you dont work there
anymore tho.
i know its been a while, but do you get what im saying now mate? theyre not
only heaters- the flow of oil and coolant happens all the time so seeing as
the coolant is cooler than the gearbox oil at normal operating temperature
the heat exchanger is cooling the oil rather than heating it. sweet?
That doesn’t sound too bad…so long as that’s ALL you have to do
differently. I don’t remember my radiator being as exposed as it is in the
video. I think something is blocking it. But, I could be 100% wrong.
thank you
Any way you can write a guide on how to do this on an E90 335xi? I don’t
want to get myself into something I can’t finish on my daily driver…
BMW must agree as they installed an air to ATF cooler on certain V8 840i
and indeed continue to have one on the DCT equipped M3 which has a valve
mechanism which switches the transmission fluid flow from the heat
exchanger to the auxiliary cooler at higher temperatures.
another question I have is, What is the average kilometer/mileage do you
see electric water pumps on e90 fail, and what are the signs of it failing?
I have an e90 n52b25 engine with 103,000 kms should I change the pump or
should I wait a bit ?
Fantastic video! Very informative, & well explained!
i wish i had a lift accessible to me hehe
Hey, I got the low coolant warning light this morning so I just added about
600ml of bottled water to because the level looked pretty low, will this be
okay until I can go get some coolant sometime next week? Thanks!
hate to lay some truth on you man, but i worked with these things and i
know a bit about how they work. they work exactly how ive told you.
automatic transmission normal operating temps around 180-200 degrees,
coolant at normal operating temp 130-140 degrees. coolant heats when cold,
then cools when hot. please believe me
However, I’m hoping I bled it correctly. I filled it with the bleed screw
loose. As I ran the electric pump, I periodically closed the bleed screw to
let pressure build up, then loosened it to get the air out. After it
stopped running, filled up the res with the bleed screw loose, then went on
my way.
sounds pretty good mate, as long as you had coolant without bubbles coming
out of the bleed screw hole you should be sweet. good job
Obviously you don’t buy into the BMW “lifetime fill” coolant myth. Care to
comment on “lifetime fill” for transmission of any type? Would love to see
a DCT drain and refill tutorial.
Are you citing ° C or F? I am rather confused by your post. Last two
sentences need to be brought to the attention of physicists world wide.
