Martin M Posted December 31, 2018 Share Posted December 31, 2018 Hi, I´m filling the engine bay of my Vitesse restoration project (o.k. a conversion of a Herald Estate towards 2 ltr drive train). There is only room for the standard blade fan on the crank OR an electric fan. In all my other cars (GT6 MK2 and Spit 1500) I have both and I´m very happy with that. What are your observations / experiences. What makes sense for a car that will be used for holiday tours, from time to time to commute to work , …... Cheers ans Seasons greetings Martin p.s. I tried to use the search function , but … :( Quote Link to comment Share on other sites More sharing options...
RobPearce Posted December 31, 2018 Share Posted December 31, 2018 Either/or works fine. My first Vitesse had the original fan and never gave any problems at all. My current Vitesse has only an electric fan and also gives no problems (except when the coolant has leaked out but that's a separate issue). My GT6 has only the original fan and the only time I can remember it overheating was on the 2002 RBRR when the fan belt disintegrated.

Nick Jones Posted January 1, 2019 Share Posted January 1, 2019 I have an electric fan on my Vitesse, but only because the need for a trigger wheel for the EFI system meant there was no longer room for the engine driven fan. There really isn't much room for an electric fan....... but it is possible if you get the right one and that works fine too. Of course, you also need the electrics for that.....

glang Posted January 1, 2019 Share Posted January 1, 2019 Yes theres examples of both set ups working well so the only differences I can see between the two are power consumption (hotly debated.....) and the possibility for an electric fan to run on after stopping the engine. I have mine set up like this and it does prevent the high temperature overshoot I was seeing when turning off the ignition after a higher speed run. It draws around 12A and my dynamo handles it fine although I do have a larger capacity battery fitted. Quote Link to comment Share on other sites More sharing options...
glang Posted January 2, 2019 Share Posted January 2, 2019 Of course I forgot one important difference and that is reliability. A mechanical fan is inherently less likely to fail than an electric one .... Quote Link to comment Share on other sites More sharing options...
Martin M Posted January 2, 2019 Author Share Posted January 2, 2019 thanks for the comments, so I will leave it as is with the standard fan. Martin Quote Link to comment Share on other sites More sharing options...
glang Posted January 2, 2019 Share Posted January 2, 2019 I think the efficiency of either set up depends largely on the engine's internal cleanliness plus, obviously, the condition of the radiator..... Quote Link to comment Share on other sites More sharing options...
Martin M Posted January 2, 2019 Author Share Posted January 2, 2019 Radiator is new with uprated core (they say) engine is rebuildt and waterways were cleaned Martin Quote Link to comment Share on other sites More sharing options...
Nick Jones Posted January 2, 2019 Share Posted January 2, 2019 Should be fine. You may find it gets a bit warm when driving fast (70+mph) on a hot day. Mine (with uprated rad with extra tubes) does. I think the problem is getting the air out of the engine bay fast enough to give enough flow through the radiator. Not overheating as such, just running hotter than usual.

glang Posted January 2, 2019 Share Posted January 2, 2019 Ive recently found out that a lot of 'modern' cars have their temperature gauges controlled by black boxes which keep the needle artificially fixed in the mid position under all normal conditions. I think that explains why its perfectly ok for the reading to move around a bit on our cars..... Quote Link to comment Share on other sites More sharing options...
daver clasper Posted January 13, 2019 Share Posted January 13, 2019 I always assumed with all the sensors etc on moderns, it was that, keeping the coolant rock steady. Quote Link to comment Share on other sites More sharing options...
glang Posted January 13, 2019 Share Posted January 13, 2019 well the temperature of the coolant still fluctuates with load, speed and fan operation and the sensor correspondingly changes its output which is sent to the black box to be used to control the fuel injected and other things. However then the black box sends a different output to the temperature gauge - one that is constant unless the the original sensor signal goes outside a set range, up or down....
