Coolant Question....
Hey guys, I went to check my coolant today and based on the diagram on the coolant tank and what I read, it seems a bit low.. I never got the "low coolant" light and my temps stay at 210-230 at some hot highway runs. I dont know if I should add coolant?

Tap the bobber to make sure it isn't stuck then add distilled water if needed. Would worry about adding antifreeze unless your expansion tank is empty and at that point you have larger issues.

That seem very low to me. Im surprised you dont have "low coolant light" on yet. Push it down couple times make sure is not stucked like mentioned above. Coolant bobber should reach about an inch above reservoir when full.

Yeah, no light, car operates fine, I'm surprised myself, but there is coolant seen on the bottom of the tank, which is hard to tell by the photos! |

Yeah, I've added coolant before to my previous cars, I'm just confused why its not throwing the light even though it looks a bit short on coolant....any ideas of how it measures the coolant level?

Another question...I just checked my coolant again and the coolant in my 335 is like light green-ish/blue-ish ..the one I bought from the dealer is mostly blue.. am I ok adding that??
EDIT: realized the BMW coolant is 100% coolant, if I mix it with some water it should become lighter Last edited by SM335i; 06-21-2013 at 02:34 PM.. |

That stick that is in the coolant tank has a sytrofoam float with electrical contacts on it that measures the level of the liquid in the tank. When it gets too low, the float bottoms out, the electrical connection is made and triggers the warning light.
