    Default Driving in extreme heat in NSW the other day.

    Hi guys,

    Advertisement


    I was driving my 180 in Sydney on Wednesday. The thermostat at the trip meter said 47 degrees. The coolant was at 100. But the most worrying thing was the fan was extra noisy. But the extra noise comes and goes during the trip. Is that normal? Is if just the fan working harder because of the heat? Can anyone shed some light on this. Thanks

    im not familiar with your model but check to see if a second fan comes in on a thermostat at a certain temp,this could explain the coming and going noise and the fan stopping when the car goes below said temp and coming on when above-BAZZ

    Sounds like the 2nd fan kicking in. I'd get it checked out at your next service, just to ensure the fan is nicely balanced.

    Fans make noise because they're spinning in the air... you won't change that... balance won't make any difference, and I doubt that anyone would do anything other than laugh at you if you went into a dealer and asked them to ensure your fan's balanced!

    No, I take that back. They wouldn't laugh... they'd rub their hands together, write 'checked fan balance' on the bill and charge you for doing nothing...

    From someone who lives in a place where it gets real warm. Yes the fans can be noisy, but you only noice it when you stop and they kick in. Standing at the door the heat wafts from under the car. When moving again the fan stops, they have to run fast to get the same sort of level of cooling driving the car provides.

    Haha. Well when a car is under warranty... you'd probably end up with a new fan at no cost!

    How do you know it's out of balance?

    Truly, if it was, it would stuff the bearings in the electric motor in very short order...

    because it has bent the shaft on the motor that drives it and yes the bearings in it are on their way out

    and i know it is out of balance as there is a small piece missing on the outer edge of it from when the screw let go and it spun off and got damaged in the process

    So this is a problem, not like the one described above... merely thinking that fan noise indicates balance issues...

    I lost a fan blade once and the car shook like the engine was falling out of it. Mind you, I was doing about 135kmh... but I was really relieved the engine didn't have a serious fault... established by looking forward and seeing the fan blade poking up through the bonnet!

    Yeh, on my 138 the fan is pretty noisy when its a 40 degree day. Can only hear it when the car is stationary as already mentioned.

    I can't hear my fan, the engine's too noisy... But my temp was up around 100 deg, at one stage it even rose up a tad higher for a minute or two. I'd say my fan kicked in cause it dropped quickly.

    So I take it that it is just the second fan kicking in and it is normal. Since I had my car in April, it has never been this hot, not even during my driving trip to Alice Springs. So my second fan hasn't worked since April, talk about a cushy job!

    Absolutely normal...

    And a trip to Alice would be easier than driving up the streets of Parramatta... because you have some speed up to force air through the radiator.

    Thanks for that Ray, I too thought that slightly out of balance fans caused extra noise, not caused by changes to the air movement but by the imbalance causing resonation in the body panels, etc.

    Oh, they might well do...

    But the sound of the fan is loud enough to cause concern.

    Putting this all into perspective for you, the average hot water system is set to deliver water at 55 - 60 degrees.
    How's that make you feel?

    If it ain't broke, use a 12" shifter.....that usually does the trick!!

    Is it a two speed fan? Might explain why there are different levels of noise...

    I wonder at what heat will the external temp sensors malfunction?
