WJA Posted May 23, 2016 Report Share Posted May 23, 2016 My 6 overheated a couple of times in traffic last summer and so I am considering fitting an electric fan. I can find two kits available on the internet a Kenlow and a Revotec. Any advice on which is better and how easy/difficult each is to fit would be most welcomed. Cheers.

RogerH Posted May 23, 2016 Report Share Posted May 23, 2016 Hi, welcome to the forum - have you a name. All of the kits work - some better than others, some a bit complicated. But you don;t need a kit. Go to the scrap yard and get a fan and cobble together I have a Pabst fan from Revington and was attached to the Rad core with plastic ties. These do work very well and do no damage. I have since welded brackets to the rad frame and attached the fan in a more structural. The thermostat can be fitted into the top hose or better still a dedicated down pipe Fit an over-ride switch Use a relay to supply power tot he fan and have the fan power line fused (20amps) Get the biggest fan that will fit the core.

peejay4A Posted May 23, 2016 Report Share Posted May 23, 2016 I have a Revotec which came with a laser cut mounting bracket, not those through the rad plastic thingies. It's very good. Quote Link to post Share on other sites
Alec Pringle Posted May 24, 2016 Report Share Posted May 24, 2016 " These do work very well and do no damage. " You may very well think so . . . . . until such time as something comes a tad loose, or starts to vibrate, and then the radiator springs a leak and dumps all the coolant. There's always a better way than mounting through the core . . . . Cheers Alec Quote Link to post Share on other sites
ed_h Posted May 24, 2016 Report Share Posted May 24, 2016 This is a 16" Spal, and appears to be about the largest size that will fit well. I'm in the US--don't know if Spal is available where you are. Mind the thickness (front to back) limit. You only have around three inches to work with. Ed Quote Link to post Share on other sites
jimcwestie Posted May 24, 2016 Report Share Posted May 24, 2016 I have a Revotec fan on my TR6. It is an excellent fit and so far no problems. I am a happy customer. Jim Quote Link to post Share on other sites
Guest Posted May 24, 2016 Report Share Posted May 24, 2016 UK's Pacet makes great fans as well http://www.pacet.co.uk Pacet produces 'pushing' and 'pulling' fans. Make sure you get the right one. Or, if it's a more generic fan that you buy, make sure it's turning into the right direction... Some have a switch (at least, that's what've heard - but haven't seen one!) others need to be wired the right way to do the pushing/pulling job properly. Mine is a slim line fan form Pacet that fits between the rad and the engine. The suggestion of making a bracket is a good one, for the reason mentioned by Alec.

Andy Moltu Posted May 24, 2016 Report Share Posted May 24, 2016 My experiences with the Revotec switches are that they are unreliable (and I am not alone in that). Can't comment on the fans themselves Quote Link to post Share on other sites
Steves_TR6 Posted May 24, 2016 Report Share Posted May 24, 2016 On the one hand 'it's a fan they all work' However : Do fit a relay as the standard TR wiring, especially the ignition, is not up to the added load. Consider whether you want the fan to run after you switch off the engine, and arrange relay feed accordingly Consider where the thermostat is located, I think the lower hose is the best location Steve Quote Link to post Share on other sites
TriumphV8 Posted May 24, 2016 Report Share Posted May 24, 2016 (edited) Have the fan with a viscous coupling from engine side and two very small fans in the top area in the front. They are started by Megasquirt and have a small hysteresis of only 1.5 degrees. Also they are switched off under 700 rpm. So they give a short shot when required and are quiet most of the time. Has the advantage that the engine fan does not rob power and the small fans in front are not in the airstream. Additionally the engine compartment is proper vented in traffic jam and does not get that hot when stopping. The V8 required larger improvement: He got a thicker core, a bigger fan from Ford Transit inside and two big fans in front from Kenlowe which draw 25 Amps each. Mille Miglia/Italy requires bulletproof cooling because there is a unhealthy mix of steep hills and traffic jams. Edited May 24, 2016 by TriumphV8 Quote Link to post Share on other sites
RogerH Posted May 24, 2016 Report Share Posted May 24, 2016 Hi Alec, you're probably right. Mine only lasted 15 years with no issue until I had to remove it for another reason. There is nothing wrong with the plastic ties if they are fitted correctly and with all the little spongy things etc. Menno has jolted my memory it is a Pacet fan that I have - very good.

If we assume that your 6 has an engine driven fan, to be overheating you have some other issue that will not be resolved by fitting an electric equivalent. Try flushing out first, then a new radiator, they don't last forever. Jerry Quote Link to post Share on other sites
peejay4A Posted May 24, 2016 Report Share Posted May 24, 2016 (edited) Why not run a temporary earth to test your theory? Whoops, posted in the wrong place. How'd that happen? Edited May 24, 2016 by peejay4A Quote Link to post Share on other sites
Barbusmaximus Posted May 24, 2016 Report Share Posted May 24, 2016 The fans in the Revotec kits are Spal fans and are designed to run 24/7 I was also pleased to note they run on a bearing rather than a bush which can wear I've never had an issue with them . Quote Link to post Share on other sites
RogerH Posted May 24, 2016 Report Share Posted May 24, 2016 Hi Barbus, that's a fishy handle Roger Quote Link to post Share on other sites
