mr_mcp Posted March 8, 2010 Share Posted March 8, 2010 I was looking at getting a x-eng fan controller but they're out of stock at the moment. I need one by Saturday so will have to get one elsewhere (probably here), however I just wanted to confirm the size. I assume that for a 94 Defender 90 a 38mm diameter EFC will do? Thanks in advance, mr_mcp Quote Link to comment Share on other sites More sharing options...
Dave W Posted March 8, 2010 Share Posted March 8, 2010 38mm is correct, the only caveat I would add is that the Merlin one has too large a range IME. You have to set it to come on when the temp is very hot in order for it to turn off before the thermostat closes. Not really a problem for a road motor but I prefer the fans to come on earlier off road when cooling may already be compromised by mud. As an alternative you could get one of these... http://www.cbsonline.co.uk/in-line-temp-sender-housingair-bleeddrain-38mm-int38-1171-p.asp With an M14x1.5 thread to give you a choice of 4 different temp range switches. With a suitable switch such as... http://www.cbsonline.co.uk/fan-switch-9785c-m14-x-15-fansw4-3530-p.asp They do different switches with different switching ranges. Significantly cheaper than the Merlin one too. Quote Link to comment Share on other sites More sharing options...
