Rs2oo Posted November 18, 2015 Share Posted November 18, 2015 Thought some of you may find this helpful or interesting. When my 350Z was M.O.T.'d recently, it overheated. For a while after, the temperature was going up at idle and almost overheated a couple more times. Into my mates workshop and after reading about slow and dud cooling fans we discovered the fans were not starting on their own, I had to flick them with my fingers to get them spinning and when they did, they were slow, one more so than the other. This I think is probably the reason behind some head gasket problems. I phoned Nissan Dartford who quoted me £861.60 for two fan motors. Yes I know. My mate does things differently sometimes and wanted to fix it without the ridiculous expense so we have fitted a fan from a Lexus iS200. Similar in size but only two of the holes which secure it to the cowling actually fit so a new hole needs drilling. The plug in bit does not line up with the recess for the Nissan plug so some of the plastic has to be cut or ground out to accommodate it. The actual fan blades are the exact same size as the Nissan part so once centralised it fits like a glove. The main body of the fan has to be cut down as its too deep and rubs. That's it, done. We have kept the right hand fan ( passenger side/air-con cooling ) after putting an air pipe in it and some lubrication. The Lexus fan is at least twice as powerful as the Nissans and although is noisier it does a fantastic job. No specialist tools required and just a used 2004 Lexus fan. The guy who did it is Allan at The Meopham Toyota Centre 1 Quote Link to comment Share on other sites More sharing options...
Payco Posted November 18, 2015 Share Posted November 18, 2015 (edited) Useful,many members upgrade their fans to the Mishimoto fans which drop straight in and are much better. Edited November 18, 2015 by Payco 1 Quote Link to comment Share on other sites More sharing options...
Rs2oo Posted November 19, 2015 Author Share Posted November 19, 2015 Just had a look on their website and they look good. Why are Nissan charging £861 !!!!!!! If my Lexus conversion does not last I will be ordering these for sure. Quote Link to comment Share on other sites More sharing options...

Rs2oo Posted November 19, 2015 Author Share Posted November 19, 2015 The original fans are remarkably silent but a noisy fan is somehow very reassuring ! The Lexus one we fitted is loud but not intrusive. Quote Link to comment Share on other sites More sharing options...
