335i (N55) Coolant

[Bezerk]

I am out of coolant.
Anyone know which kind of coolant to put in and what ratio of coolant to water to use?

It doesn't mention the ratio on the bottle or car manual.

I have a bottle of Halfords red stuff but don't know if that's any good.

An internet search gives the usual mixed opinions!

Placed a called with BMW, but they haven't called me back...

I wouldn't use the red Halfords stuff you have, just get a bottle from your local bmw dealer ( around £7+ for 1.5litres) and mixing it 50:50 with distilled water.

First thing I'd look for is where the coolant has gone.......................

Thanks. I added 500ml water and that took it up to the minimum level.
Dropped it off at the dealer so they can investigate and top it up with correct coolant.

Doesn't help having a black plastic coolant tank.
You can't see the level below the minimum mark, or the colour of the liquid.
