    Coolant Question

    I just got my 89 325I vert and I noticed that the "Cold Coolant Resevoir" looks low, and the light on the inside check panel is lit up for coolant. Can I just add any type of coolant to fill it up? I am eventually going to do a coolant flush and freshen all the fluids up, but I need this thing to get me about 2.5 hours home next weekend, before I can really do any work on it.
    Any suggestions would be great. Also I need to mention that I have driven the car around and it has not been over heating.

    Thanks!

    Look on the coolant tank. You will see a line where the coolant is supposed to be...don't overfill. Use a proper 50-50 mix of coolant/water.

    Coolant level sensors are often pre-failed, but easy to fix.

      I read that it should be about where the tank splits into the lower section and upper section. I didnt see any marking or anything on it. IS there an arrow or something? Also if it is low, what coolant should I get?

        If it is just the reservoir that is ~50% low I would just use distilled water to fill it back up.

        I been using the BMW coolant mixed 50-50. I believe there is a Prestone equivalent.

        My reserovoir full marking is on its very top on a lil rectangle.

        I have had bad luck with used old sensors. I have gone through two used ones from part cars and they both been flaky. You can clean them and get them running again but start throwing a light shortly thereafter. One thing to do is bypass the thing by jumping the connector, ei taking a wire and looping the terminals of the connector with it. Or buying a use one for cheap, or a new one for ~$25.

          Ok so I should just try some distilled water? Also I noticed earlier this morning, it looks like the tube that is in front of the actual airbox is dried out and cracking. The part thats approx. 4" in diameter and looks like it is suppsoed to connect right behind the headlight.

            Would it be wise to get some prestone coolant or the 50/50 prestone at the local Autozone to top off the tank so i can get her home ok this weekend? I dont want to dillute it too much by just adding distilled water.

              It is still quite a while before really cold weather. And you should do a coolant change if what's in the car is two years old (or of unknown age). So just top up with water (plain or distilled, it won't really matter).
              The car makes it possible, but the driver makes it happen.
