Coolant level E89 - should it ever need topping up?

[tonyg]

Hi, me again, with my newly purchased 2015 E89 that I think I love - but not sure just yet, given the various problems lol !!!!!

Put simply, should the coolant level ever need topping up? The coolant light went on a week or so ago and my dealer topped it up. Obviously I'm slightly worried whether it could be something more serious. (My old 3-series E36 I don't think ever needed to be topped up in 20 years of ownership!!)

Does coolant need topping up every now and again?

Thanks in advance, Tony

No. It's a closed system. Possibly the previous owner changed coolant and didn't get all the air out of the system. When the air works it's way out it will leave with with a lower coolant level. If it goes low again, have it pressure tested.

You can bleed the system yourself to ensure it’s fully purged..

As I've posted elsewhere, my 2010 35is has used between 4 and 5 litres of coolant - Comma Xstream G48 - in 70 miles.

Guidance for topping up is on page 198 of my handbook.

Isn't the coolant capacity of that engine approx 10 litres? So, you loose half your coolant in a 70 mile trip?

:roll: But not now. :wink:

Typo apart, the N54 certainly doesn't have a closed coolant system.
