Harryjax Posted September 19, 2014 Share Posted September 19, 2014 At what temperature should the cooling fans kick in and is there a way to check if the fans without running the engine? I've had a search but couldn't find any info. Any advise appreciated. Quote Link to comment Share on other sites More sharing options...
Randy_Baton Posted September 19, 2014 Share Posted September 19, 2014 Turn the ignition on and then turn the air con on full pelt, both fans should start up after a few seconds. When mine were on the way out the one fan would start and the other would need a little push. 1 Quote Link to comment Share on other sites More sharing options...
Harryjax Posted September 23, 2014 Author Share Posted September 23, 2014 I managed to have a look at this issue today. All fuses and plugs look ok but the two cooling fans do not operate. The temperature gauge goes up fine so am I right in thinking that the fan motors are at fault? Any one else had this issue? I've read somewhere that the brushes in the fan motors sometime get stuck and can be stripped down and fixed. Has anyone done this and if so was it worth while or should I just buy new / used ones.

GMballistic Posted September 23, 2014 Share Posted September 23, 2014 From a previous thread about the same thing basically.... As others have said the likely cause is the fans not working. When the car is running and comes up to working temperature you should see one of the fans start to work, if not then it's probably had it. The other fan works when the A/c is turned on so you can check that by turning that on when the cars running. Some members have taken their fan motors apart and cleaned them/replaced parts but usually this is just a temporary fix.

Another alternative is to take the opportunity to upgrade at a cost more reasonable than the OEM parts from Nissan. As Jumping350 mentioned you can get the Mishimoto fan shroud which Clark Motorsport, Tarmac Sportz and others sell on here.

andlid Posted September 24, 2014 Share Posted September 24, 2014 Test the fans operating by connecting them straight to the battery. If bust get some aftermarket ones and solder them onto the connections, I've got info on that in my build thread *if it's still alive 1 Quote Link to comment Share on other sites More sharing options...
Randy_Baton Posted September 24, 2014 Share Posted September 24, 2014 Have you tried flicking the fans to get them going? That worked on mine, so I know they are not completely dead. Still getting the whole unit replaced though. Quote Link to comment Share on other sites More sharing options...

Tricky-Ricky Posted September 25, 2014 Share Posted September 25, 2014 Once it gets to the stage where the fans wont come on until they are taped, its well past the stage where they should be removed and taken apart and cleaned/refurbed or replaced if your not inclined to do that.

Shane Brede Posted September 26, 2014 Share Posted September 26, 2014 Hi Harryjax I had the same issue when I got my Zed the fan motors were nakered here's one of many utube links to show how to strip clean & check your motors mine were beyond repair and I replaced the fans & motors.This was the first advice I was given by Mitz at Cougar Stores to check before I spent any money on new fans, apparently the motors giving up is a known issue and this is why I always go to him for advice and work as the most important thing to him was saving me money first rather than taking it off me TOP BLOKE 2 Quote Link to comment Share on other sites More sharing options...
Harryjax Posted September 27, 2014 Author Share Posted September 27, 2014 Well guys I stripped the fan motors down and took them apart to find all the brushes in both motors stuck in the housings. Once pried out I honed the carbon brushes with a super fine diamond file until they slid in and out nice and easy. Put all back together refitted on to cooling shroud placed back in car and tested. I've taken some photos so will post them up later. Every thing Woking great now even the AC. AS I ENJOY PLAYING WITH SPANNERS. If anyone else is having the same issue with their cooling fan motors and would like me to fix them FREE of charge PM me. It's an easy fix with no parts required. 4 Quote Link to comment Share on other sites More sharing options...

Harryjax Posted September 27, 2014 Author Share Posted September 27, 2014 Well as promised here's a few photos of the fan motors fixed today. This is how I found the brushes once casing removed.

Harryjax Posted September 27, 2014 Author Share Posted September 27, 2014 Brushes locked in place with opened paper clips. Place back together. Push the two parts together and tap the lugs back down then refit. Simples. Quote Link to comment Share on other sites More sharing options...
