    X5 water temp much cooler than normal.

    2001 BMW X5 3.0

    I just noticed this weekend, my X5 water temp is running much cooler than normal, even after a 30 mile drive down the highway. Normally the water gauge is at 12 o'clock position, it is now at 10 o'clock. Naturally this effects the interior heat. Car is located in Chicago - in the 40's during the day, upper 20's at night.

    I am leaning toward water thermostat but wanted to post to ensure I am not missing anything quirky about the X5.

    All suggestions welcome.

    THANKS!!

    Electronic Thermostat

    Mine did this for a long time. Didn't seem to be a big deal. finally got a thermostat error on the OBD II reader.

    I replaced the thermostat and the temp went to 12 and stayed there like a rock.

    Electronic thermostats. Water-cooled alternators. Can I go home, now?

    Might not be a bad idea to replace the water pump, serpentine belt, and tensioner, while you are in there...

    Thank You Robert, I will pursue the thermostat.

    Water pump? Is it that involved to change the thermostat? I took a peek, not a lot of room, granted.

    Some folks believe that it is a good idea to change the water pump every 100,000 miles before it fails. In some older BMWs this was a problem as the seals would fail and then the pump bearings go south and then it leaves you stranded on the side of the road one dark and stormy night. It is a cheap part and easy to replace - if you are replacing other cooling system components.

    For the E36, for example, people recommended replacing the whole cooling system, which I did with both my E36's. The cost was about $500 in parts.

    See:

    For newer BMWs this may be less of a problem. The quality of the components is better, I think.

    One fellow on the Z3 forum ridiculed the idea of replacing these parts before they failed. He claimed they never failed. Well, you can guess what happened to him right after that...

    I always use BMW coolant and distilled water in a 50/50 mix and change the fluid every few years or 30,000 miles. This should be done carefully, as on some BMWs, you can get an air bubble in the head and blow the whole motor, if you are not careful.

    FWIW.
