    Heater blows - no heat. Engine temp does not go up normally.

    Decided to drive 8 hours for new years to minnesota - 2 hours in heat goes out .

    My engine temperature moves but it doesn't clear the left most blue area - usually it sits about half way from left to right. So I'm thinking this is a thermostat problem?

    I get air flow, which is fine, but it blows air that is barely above the ambient inside temperature.

    I read on here that maybe something in my radiator is clogged - how can i check that?

    Your thermostat is stuck open. Replace the thermostat.
    In case the radiator would be clogged, then you would have a overheating situation.

    awesome. thanks - I assume fairly easy replacement. I'll look for a video

    Edit seems theres an 88 and 92 degrees variant for the part - does it matter? seems like that isn't going to be that big of a difference but who knows.

    The 92 deg replaced the 88 deg one. BMW had its reasons.
