2013 118i F20 N13 water pump is it electric or manual?

I'm trying to bleed my cooling system but I'm not sure if my water pump is electrical or mechanical? since both have different ways.

can anyone confirm this for me?

It's "manual"/mechanical: https://www.realoem.com/bmw/enUS/sho...diagId=11_4998.

There's a lever in between the front seats, you should use it to pump.

No I don't. But people seem to (and that should be applicable, see below):

,

see the highlighted comment.

N13 does have an electric auxiliary water pump. I would guess the F20 shown in the first clip above (diesel?) has the same double-pump cooling system, feel free to dig it (RealOEM) to make sure.

I drained and refilled my 2014 116i without activating the pump. (you can turn it one with a suitable code reader).

I had to keep topping up the reservoir whilst idling after refilling but not had any problems with airlocks since.

This is irrelevant here. But on RealOEM select your own car, of course.

I have bimmerlink, will that work?

do you mean since you refilled you kept having to top up? or do you mean while bleeding?

I just filled up as I have always done on any vehicle.

Fill to the mark, run the engine, level drops, stop engine, top up again, start engine and repeat a few times until engine is up to temperature.

Then leave overnight and top up again if necessary, then check daily a couple of times.

The level didn't drop again after 24hours and a final top up.

i don't think Bimmerlink nor Bimmercode will do it.

did you do the bleeding process? or just on and off the engine?

It never occurred to me that there was a specific bleeding process so, no I just filled it as described.
i did the same on a Golf GTE with no side effects.

It seems to me that the bleeding process is just there to speed up dealer coolant changes and avoid customers complaining about low coolant level which will happen if you don't use it.

If you are happy to check it for a day or so after refilling, then you know what to expect.

problem for me is I've been topping up coolant but it disappears but there is no leak or anything.

it drops to minimum level but water temperature is still stable at 105.

I had an Alfa Brera 3.2l V6 that seemed to be using coolant. I kept topping it up to the mark and then a few days later it would drop to the min level.

I stopped topping it up and the level didn't drop any lower.

So I concluded that when topped up to the line cold, the expansion caused a small loss when hot.

What stopped me doing endless topping up was the amount of coolant needed. If your's always takes the same volume to top up to the line, then there can't be a leak or the volume would depend on how long you left it before topping up again.
