ausgolfer 0 Posted March 11, 2014 Hey guys. Simple question. Can a noisy rad fan be fixed/refurbished? Cheers. Quote Share this post Link to post Share on other sites
sankysvr6 0 Posted March 11, 2014 Only one way to find out, is to have a go at it. What's the worst that can happen, either get nosier or stop working altogether. Quote Share this post Link to post Share on other sites
Stonejag 10 Posted March 11, 2014 The worst that can happen is that it seizes and catches fire. No joke, it's happened to me twice! They're downright dangerous IMO. Bin it and replace with a single-stage Spal fan wired direct to the rad sender. Stone Quote Share this post Link to post Share on other sites

Stonejag 10 Posted March 11, 2014 I'm sure you can replace the bearings, I just have no idea why you'd want to. The coolant system is already hopelessly overcomplicated, there are so many different points of failure that you've got little hope of ever having it all working at once. Plus, when it fails, it tends to do so in a way that endangers your engine (or your whole car), and even if you save the vehicle the parts costs are horrific. Think a set of genuine fans cost me over £400 with the VAT last time, never again! :nono: Stone Quote Share this post Link to post Share on other sites
VW_OwneR_85 1 Posted March 11, 2014 The worst that can happen is that it seizes and catches fire. No joke, it's happened to me twice! Stone sorry but I had a little chuckle at this with sankys comment , all jokes aside that's pretty much the worst thing that could happen! Quote Share this post Link to post Share on other sites
ausgolfer 0 Posted March 12, 2014 Honestly after this mornings drama I agree! I've been driving my G60 daily for nearly a year now. And I seem to have a new issue each week. Last month the throttle broke. Constant danger of overheating on top of the noisy rad fan. And this morning the fuel hose and clamp jumped the spool and started leaking down the chassis leg. Could have easily lost the car if I didn't live so close to work(short trip). Ordering a cruddy Yaris lease car again.... Quote Share this post Link to post Share on other sites
sankysvr6 0 Posted March 12, 2014 (edited) sorry but I had a little chuckle at this with sankys comment , all jokes aside that's pretty much the worst thing that could happen! But it would have fixed the whine of the fan :-) Edited March 12, 2014 by sankysvr6 Quote Share this post Link to post Share on other sites
Stonejag 10 Posted March 12, 2014 You're right, when it's melted into a solid lump that glows dull orange it's almost totally silent. My swearing, on the other hand...not quite so silent :bad-words: Quote Share this post Link to post Share on other sites
robwillz 10 Posted March 13, 2014 My fan on my vr is noisy on the fan there well looks to be a rubber ring what should sit snug on something. Id have.to get a pic to shpw ypu all. Quote Share this post Link to post Share on other sites
Jim 1 Posted March 13, 2014 There are plastic fan 'guides' that clip into the metal radiator fan housing - I suppose it's possible one of these has broken and come loose? If it is one of these, they are still available from VW and not very expensive. Quote Share this post Link to post Share on other sites
ausgolfer 0 Posted March 14, 2014 Bin it and replace with a single-stage Spal fan wired direct to the rad sender. Stone Stone. This mod you're suggesting sounds good. Would that do away with the sensor that sits up near the intake manifold? I'm not even sure mine works. Quote Share this post Link to post Share on other sites
fla 9 Posted March 14, 2014 you can just connect it to the rad fan connector bridging the wires for speed 1 & 2. Bear in mind that the fans will always receive the full 12V so will be on at full speed for maximum cooling. I have aircon in mine and have fitted 2 spal fans, perhaps a bit of overkill!

Sean_Jaymo 0 Posted June 2, 2014 After having a slightly noisy fan and ignoring it as it didn't sound that bad, I could have paid the consequence over the weekend when mine melted leaving a lovely smell and some nasty smoke. Luckily, it never caught fire but it did make me pretty concerned that something so simple could endanger the entire car! Morale of the story, if the fan is even slightly noisy, don't ignore it!

Stonejag 10 Posted June 4, 2014 Like I said, the worst that can happen is they catch fire...I've kept a ten-mil spanner in the door pocket for rapid battery disconnection ever since the first time, which is what saved the car the second time. I removed the fan controller too, replacing it with a single 40A relay plumbed into a low-temp single-stage switch in the (M22) sensor hole in the lower-right corner of the rad. When I get around to it I'll run two more wires to run the aux coolant pump whenever the fan's on, which should help as it still overheats (slowly) in town traffic when the engine's idling and the main water pump isn't running that quickly. Be aware: if you remove the fan controller you may lose the live feed to one of the thermostat housing sensors, which will cause a VAG-com error and occasional difficulty starting (as the ECU assumes a coolant temp of 70℃ when the signal's absent). When I get around to removing the remnants of the harness I'll replace it... Stone Quote Share this post Link to post Share on other sites
