Martin J Posted June 25, 2009 Share Posted June 25, 2009 You have two fans fitted Perhaps one is for the air con. Link to comment Share on other sites More sharing options...
geko Posted June 25, 2009 Share Posted June 25, 2009 Hi, I don´t know it for sure but I think about 105°C, never seen much more. Best regards Gerhard Caterham CSR 200 MAZDA MX-5, NB, 1840ccm Edited by - geko on 25 Jun 2009 23:19:28 Link to comment Share on other sites More sharing options...
tbird Posted June 25, 2009 Author Share Posted June 25, 2009 Martin Hi, Nope they are both for cooling, but maybe air con would be nice for the tunnel, I wonder if I can squeeze a 3rd in somewhere, maybe like the old Brabham BT46B to suck air from underneath and vent through the gear shift gator Gerhard thanks for info I am a little happier now Link to comment Share on other sites More sharing options...
Martin J Posted June 26, 2009 Share Posted June 26, 2009 I would of thought it was a bit tight for two fans but I suppose there is more room in the CSR compared with my S3. Out of interest, are the fans fitted side by side of does one suck & one blow? Martin Link to comment Share on other sites More sharing options...
tbird Posted June 26, 2009 Author Share Posted June 26, 2009 Martin Side by side in the lardy nosecone, you had me thinking I was imagining things when you replied, had to check on CC website, (garage is about 10 minute walk away), Luckily it confirmed Cooling fan CSR 2 required per car, phew senility not set in yet 285mm diameter both sucking cheers Tim Edited by - tbird on 26 Jun 2009 23:28:41 Link to comment Share on other sites More sharing options...
Gridgway Posted June 28, 2009 Share Posted June 28, 2009 I don't think the fan(s) should kick in at 105. I thought it was more like 97. Graham Link to comment Share on other sites More sharing options...
geko Posted June 28, 2009 Share Posted June 28, 2009 Hi, 105°C on the gauge, the sender is fitted in the coolant-rail above the exhaust. From CC HP: The fan switch kicks in between 86 - 95°C Best regards Gerhard Caterham CSR 200 MAZDA MX-5, NB, 1840ccm Edited by - geko on 28 Jun 2009 18:35:38 Link to comment Share on other sites More sharing options...
tbird Posted June 28, 2009 Author Share Posted June 28, 2009 Thanks Guys I feel a physical inspection coming on, with the hot weather coming hopefully I can get the temp up far enough to lift the bonnet and have a look Tim edited to replace drivel Edited by - tbird on 28 Jun 2009 21:37:30 Link to comment Share on other sites More sharing options...
