What Coolant? - BMW 3-Series (E90 E92) Forum

I have a warning indicator saying coolant is low? What Coolant should I top up with?

I rang the dealer yesterday (Bib Stillwell) and they took a message and said they would ring me back, but as usual from that dealer, no one ever rings you back.

fill it with distilled water. radiator coolant is a mix of half water and half coolant.

I topped up using BMW coolant. It costs $20 for 1.5 liters but didn't need it all. If topping up with water forum members recommend using distilled water.

Thank you will get some distilled water.

If you are in Sydney I will give you some. I bought some from BMW for the same reason, I got a warning light saying it's low, only needed about 10% of it to top it up.

If anyone in Sydney needs some, PM me, I think all the models use the same coolant as BMW seems to only have 1 type of it.

Is there any particular problem caused by using normal tap water instead of distilled water, eg does it cause corrosion in the engine?

A few times throughout the ownership of the vehicle should be fine, but with continued use it will cause corrosion and rust to settle in.
