Astro_Al Posted July 19, 2006 Share Posted July 19, 2006 wassit powered by??? Got to be the water pump, no...? Quote Link to comment Share on other sites More sharing options...
Turbocharger Posted July 19, 2006 Share Posted July 19, 2006 We have hydraulic fans on most of our buses - oil fed from the PAS system. Point of no interest whatsoever - leaky pipes on here count as a leak from the steering system at MOT. Quote Link to comment Share on other sites More sharing options...
dollythelw Posted July 19, 2006 Author Share Posted July 19, 2006 the blueness was an all over occurance on this wagon, its a Russian car from the NightWolves club, its a bit tasty but Im interested if this is a standard Toyota part and what was it powered by... could be water pump..

Daan Posted July 19, 2006 Share Posted July 19, 2006 hydraulic fan. I saw that in the last RFC on a toyota based vehicle to cool rear mounted rad. Fan was of toyota hiace van i believe. Powered by powersteering circuit. I am one of the few believers (the only one?) of good old viscous fan though but what do I know...

Tonk Posted July 19, 2006 Share Posted July 19, 2006 I am one of the few believers (the only one?) of good old viscous fan though but what do I know...Daan i even missed the viscous unit out, bolted straight onto w/pump, if the engine is running then the fan is turning, one less thing to worry about imho Quote Link to comment Share on other sites More sharing options...
white90 Posted July 19, 2006 Share Posted July 19, 2006 Daan your not alone I've purchase 3 viscous units in my time v deep water crossings appear to ruin the bearings it would seem as soon after a bout of deep wading the bearing develops play the latest(brand new} seems to be lasting well so far 2nd brand new one I purchased though Quote Link to comment Share on other sites More sharing options...
dollythelw Posted July 19, 2006 Author Share Posted July 19, 2006 I cant have rads in normal places so conventional drive is out for me Daan, interesting idea about spurring off the PAS pump, Ive got 12ltrs/min so plenty to spare is it from a Hiace then??? mind you if its spurred from the PAS circuit there must be a flow control valve or the PAS would have a bad day when you turn the wheel?

Daan Posted July 19, 2006 Share Posted July 19, 2006 It was plumbed in in series with the normal Pas system, so it will see the flow (and pressure?) of the pas system. Problems: No temperature control and no pas=no cooling. daan Quote Link to comment Share on other sites More sharing options...

It works well, for back up I drilled the boltheads in the water pump and the fan, so you can lockwire them in case it stops working. Quote Link to comment Share on other sites More sharing options...
dollythelw Posted July 19, 2006 Author Share Posted July 19, 2006 not sure I'd like it in series , relatively straightforward to give it temperature control though, If my PAS fails cooling wouldnt be my biggest prob Quote Link to comment Share on other sites More sharing options...
Les Brock Posted July 19, 2006 Share Posted July 19, 2006 Daan, No your not alone, after having electric fans on my 200 Tdi, I've gone back to a viscous, although I've fitted a 300 Tdi one as it has more blades, although you have to cut them down slightly and a huge viscous unit...and so I'm told more reliable one and the main reason it only cost £5 from E-Blag Quote Link to comment Share on other sites More sharing options...
Daan Posted July 19, 2006 Share Posted July 19, 2006 good to know I am not alone.... Dolly, I dont think parallel would work, as the oil would choose the way of the least resistance which normally is the box, untill you turn the wheel, in which case its the fan. So none of it would work anymore. Or did you have something more clever in mind. Im sure you have. Daan Quote Link to comment Share on other sites More sharing options...
dollythelw Posted July 19, 2006 Author Share Posted July 19, 2006 just a flow restrictor so the fan sees a constant flow - maybe that would work?, put a solenoid in line and hook that into a conventional thermostat - I like the idea of waterproof fan power as opposed to having to mount mine at jumbo jet cruising height, what do you think?

Andy Posted July 19, 2006 Share Posted July 19, 2006 got those on all our coaches, if i remember i'll ask how its plumbed for you. Quote Link to comment Share on other sites More sharing options...

jules Posted July 19, 2006 Share Posted July 19, 2006 I am still on the original (300 tdi) version. It works well, for back up I drilled the boltheads in the water pump and the fan, so you can lockwire them in case it stops working. 4.2 v8 I fitted a new one when the engine was fitted four years ago and I still have the old one as a spare The RR only had 50k on the I got the engine from. Still good as new. Quote Link to comment Share on other sites More sharing options...
Andy Posted July 19, 2006 Share Posted July 19, 2006 i went leccy fan a while ago. then threw it all away & fitted the proper fan again. works much better with less hassle. as an aside, my old '78 MG went leccy fan for a while & had no end of problems with fuel vapourisation in warm weather. switching back to a 'real' fan has cured that. i guess the constant draft cools the carbs a bit.

will_warne Posted July 19, 2006 Share Posted July 19, 2006 I use viscous. I'm on number 3 or 4 (can't remember which) and I quite like them as they're nice and simple although I'm thinking about something a little differant now. Quote Link to comment Share on other sites More sharing options...
geoffbeaumont Posted July 20, 2006 Share Posted July 20, 2006 any ideas?? wassit powered by??? With that colour scheme it's got to be a bit of Catflap bling. Come on Les, own up - what have you been building? Quote Link to comment Share on other sites More sharing options...
Andy Posted July 21, 2006 Share Posted July 21, 2006 well i remembered to ask at work for you. been told the coaches have twin rotor pumps, so there is effectivly one pump for steering & one for the fan. ****roen shatxo have leccy PS pumps - hide one inside to run the fan? if you cant get enough belts on the engine of course.

Guest diesel_jim Posted July 21, 2006 Share Posted July 21, 2006 I reckon it's a wind powered hydraulic winch pump.... Gotta be faster than a milemarker!!! I suppose you could paint it orange, stand Colin in front if it, let him start spouting and run several winches off of it! Quote Link to comment Share on other sites More sharing options...
Bush65 Posted July 21, 2006 Share Posted July 21, 2006 not sure I'd like it in series , relatively straightforward to give it temperature control though, If my PAS fails cooling wouldnt be my biggest prob With normal pas, I would suggest run the hyd fan in series after the steering box. Would need to increase the pressure to suit the increased pressure drop. A solenoid operated direction control valve, controlled by a temp sensor, in the line between the steering box and fan motor, would take care of temp control.
