dirkthe1 Posted January 31, 2009 Share Posted January 31, 2009 i did a search and found this: http://forums.lr4x4.com/index.php?showtopi...20fan&st=40 i was just wondering about ripping mine of my 2.5 na diesel. i was just wondering, mounting wise does infront and behind make a difference? i geuss it just depends on the fan ( i believe air con ones are mounted in front?) having a look on fleabay for a fan, and do plan to fit an x eng thermo switch for it. cheers geoff Quote Link to comment Share on other sites More sharing options...
Ex Member Posted January 31, 2009 Share Posted January 31, 2009 Get a Mondeo fan (search). They are basically a direct fit into a 2.5NA radiator and they go in the back. Very easy and the fan is much larger than needed. Quote Link to comment Share on other sites More sharing options...
dirkthe1 Posted January 31, 2009 Author Share Posted January 31, 2009 i did see them mentioned on the other thread. but from reading people saying they barely use them, i was wondering how good the fan actually has to be? surely just having a token fan that will kick in when needed will do the job just as well?

FridgeFreezer Posted January 31, 2009 Share Posted January 31, 2009 Big, bigger, best. If you're gonna have a fan, may as well make it one that can cope with anything. Quote Link to comment Share on other sites More sharing options...

FridgeFreezer Posted February 1, 2009 Share Posted February 1, 2009 cool, just put a bid in on some range rover fans I hope you don't mean the aircon ones that keep the aircon condenser cool in summer, because those will not be up to much cooling an engine.

Ex Member Posted February 1, 2009 Share Posted February 1, 2009 Look, you just go down to the breakers and pick up a Mondeo fan. They are cheap and the best for the job. The ones in the auction are junk as they won't mount well. The mondeo fans fit great and cover the radiator properly. Quote Link to comment Share on other sites More sharing options...
Snagger Posted February 1, 2009 Share Posted February 1, 2009 I fit a 14" electric fan to my 109 because the fan mounting on a Discovery 200tdi engine is too low to use the viscous unit. The fan was used a fair bit climbing the mountains on my Alpine trip, but other than that (and sitting in traffic) it stayed off. However, I'd strongly recommend keeping the standard fan - nothing can go wrong with them, but electric fans can suffer circuit faults, failed bearings, shorting out, they drain the battery when running with the engine off and are simply less powerful and less reliable. The figures that Kenlowe publish about the fan's fuel and power consumption are utter lies - most of the time that the vehicle is moving, the fan will not have a significant angle of attack on the airflow, and so will have no significant turning resistance. When it is working hard, at high rpm and low vehicle speed, it has more effect than an electric fan but little more resistance. The energy for either fan wwill come from the engine, but the fixed fan is more efficient because you don't lose energy through transfers of state from kinetic to EM to electrical, back to Em and then back to kinetic, with losses in the wiring, alternator and electric motor from resistance and heat. The fixed fan is far superior to the electric alternatives. If you look at moder cars, only vehicles with transverse engines get electric fans. All others with in-line engines get engine-driven fans (usually viscous) because of their greater effectiveness, reliability and efficiency. However, if you are set on an electric fan, or compelled to use one like me, a puller fan on the rear of the rad is more effective than a pusher fan on the front.

Anderzander Posted February 1, 2009 Share Posted February 1, 2009 I follow what you're saying - but my td5 was transformed by removing the fan and do modern electric fans really fail that much? Quote Link to comment Share on other sites More sharing options...

The mondeo fans fit great and cover the radiator properly. i know that, but that involves going to breakers, getting fan, etc. if i got that for the price ive bid up to, im more then happy with it, if not i'll be going to the breakers when im over that way Quote Link to comment Share on other sites More sharing options...
FridgeFreezer Posted February 1, 2009 Share Posted February 1, 2009 Snagger - I have only known one electric fan fail and that was because the owner went deep wading with it switched on. In contrast, I have known around 10 viscous fans fail in the same time period - either losing drive/locking up or in one case losing a blade due to deep wading and trying to eat through the radiator I also believe removing the engine fan puts less stress on the water pump bearings. Arguing that electric fans can drain your battery with the engine off is only true if you wire it up so it can run with the engine off.

LandyManLuke Posted February 1, 2009 Share Posted February 1, 2009 I've got a mondeo fan, fits a treat on a 200tdi rad with a little fettling. as already said it would fit a full width rad straight away. I paid £15 for two. Quote Link to comment Share on other sites More sharing options...

Lars L Posted February 1, 2009 Share Posted February 1, 2009 FWIW, I had a fan from an older Saab 9000 on my NAD. The fan casing is made of pressed sheet metal and needs to be cut back to the actual fan surround. This is then slotted so it can go onto the already existing plastic duct and be fastened with one of the big hose clamps already there. The fan wings go into the duct after they have been trimmed just a little. I just held a piece of coarse sanding paper along the opening and started the fan...

Simon B Posted February 2, 2009 Share Posted February 2, 2009 They look spiffing! Are the Mondeo units 2 speed or 1? Will need a fan when my Zuzu goes in a viscous unit would be touch remote! Quote Link to comment Share on other sites More sharing options...

Anderzander Posted February 2, 2009 Share Posted February 2, 2009 Marcus - I'm just running it without at this point! I'll fit the electric one in the summer. So far my experience has been that the engine is totally over cooled and is currently being easily controlled by the stat and normal airflow.
