lukeyy 10 Posted July 20, 2011 Hey, A new problem!! driving home from my girlfriends last night i could hear a whurring noise coming from the engine bay, this was around 25 miles of driving around 70mph, water temp and oil temp was fine, nothing alarming there. the whurring noise continued for the next 10 miles till i got home. pulled up, popped the bonnet and the radiator was going full whack, turned off car and it stopped, clicked ignition on and it started at full speed again. :scratch: Any ideas????? thankyou in advance. luke Quote Share this post Link to post Share on other sites
Critical_Mass 10 Posted July 20, 2011 fan switch in the radiator? sits between the top and bottom hose on rad. OR it could be the control box that sits in front of the coolant header tank. Quote Share this post Link to post Share on other sites
lukeyy 10 Posted July 20, 2011 alright man, it was tonight it happened, not yesterday which i wrote before. couldn't really see what was going on cos its a bit dark out ther. lol. can you test the fan switch or repair it? i'll switch the car on in the morning before work see if its still gonna go ape on me. hahaha Quote Share this post Link to post Share on other sites
Critical_Mass 10 Posted July 21, 2011 Think it will need replacing mate, assuming it is the switch. Quote Share this post Link to post Share on other sites
hombre_paulo 0 Posted July 21, 2011 Also if you have the 3rd temp sender on the thermo housing this can aslo be the cause. Try unplugging that to see if it stops the fans Quote Share this post Link to post Share on other sites
lukeyy 10 Posted July 21, 2011 hey, this morning went out turned on ignition and the fan came back on at full speed same as before. i had a play with the plugs on the thermo housing, unplugged blue and yellow individually, nothin happened, but unplugging black it turned off. what does this mean?

Kevin Bacon 5 Posted July 22, 2011 hey, this morning went out turned on ignition and the fan came back on at full speed same as before. i had a play with the plugs on the thermo housing, unplugged blue and yellow individually, nothin happened, but unplugging black it turned off. what does this mean? It means either the black sender or the fan control unit are faulty. Start by replacing the Black sender. How it all works is all in the "Definitive VR6 cooling thread". Fans / cooling and chains are the most discussed topics relating to the VR6. Basically...... Theromstat switch in Radiator = Speed 1 and Speed 2. Black Sender in thermostat = Speed 3 Yellow Sender = Fan & Booster pump run on. Pins 1 & 4. On at 100 deg, Off at 95 deg. Quote Share this post Link to post Share on other sites
lukeyy 10 Posted July 23, 2011 okay, cheers. i'll start by ordering up the black sender in the thermo housing, see if that works. Quote Share this post Link to post Share on other sites
