    Oh yeah, nothing like a nice bit of suction

    I've no idea what the difference is between the bottom two, other than the part number

    Either way, they're all around the £70 mark, which is considerably cheaper (not to mention quieter and lighter) than buying the standard fan setup from VAG for a couple of hundred quid!

    Re: The definitive VR6 cooling guide

    The difference is blade type I believe, i.e. curved blades for quiet running, or straight blades for noisy all out sucking action

    I have the curvy blades

    Speed 1 has direct battery power and will run if it's triggered.

    Speed 2 has power maintained to it only during the 10 min after run cycle and will also run only if tiggered.

    Speed 3 is ignition only.

    So if you pull up after a journey and the fans don't run, that is a good thing, not a bad thing :wink:
    Good stuff, amended the original post with this

    Great thread, been thinking for ages someone with the knowledge should do a decent write up on the subject. So thank you.

    Also would it be worth copy and pasting the first post into a wiki guide?

    And yup, if the wiki would let us edit it at the moment (it's on the to-do list)

    Forgot to say...... it's a good thing providing the dash gauge isn't reading 100+

    If temperature is normal i.e. ~ 90 degs when you stop, there's a good chance the 95 deg Stage 1 won't be triggered. It may kick in randomly as the after run pump circulates the hotter water out of the matrix and block/head into the radiator. All normal stuff.

    If the fans do nothing when the gauge reads 100 (middle), the rad switch is probably knack'd.

    If the fans do nothing past 105, the rad switch *or* fan controller is borked.

    If the fans do nothing past 110, run!!
    Nah, stage 3 switch is borked or missing in action, presumed dead....or the controller.

    I've had to replace the controller and it's an eye watering experience, £110+VAT IIRC!

    Re: The definitive VR6 cooling guide

    Can we have a 'cooling trouble shooters guide for dummies' please as this makes absolutely no sense to me....

    I've just bought an M red VR6 on 69k and the water temp reading is going up to 110, whereas the oil temp on the maf says 108 at most. The coolant is the colour of rust and the oil is black as the car has sat in a garage for 3 years - will be serviced on Saturday!

    The fans only turn on after I turn the ignition off and even at 110 degrees do not kick in until the engine is turned off?

    Any thoughts before I go and buy a 5 speed setting fan with AC????

    Biggerbigben thinks I need a new fan switch but after calling up VW they say there are several - so I said I'd find out on the C forum!

    Cheers
