Why there is nothing wrong with a good working Td5 viscous fan
You will still have the hub bearing that can fail but no biggy to fix.
Ps. dont ad different metals to the cooling system or it will end in tears stick with alloy or mild steel
Hey gang,
thinking about getting my old man to help me put in an electric fan in place of the viscous on a TD5. Mine doesn't need doing at the moment, more of a preventative idea to make more reliable. I've also heard it can save a little on fuel
Has anyone else done this? good results? Could i please get some tips on options and where to buy? Thought I read a while ago someone used a falcon one, is that correct?
Should i hook it up to AC or have it kick in at set temp?
I searched a bunch of different wordings for this and couldn't find many answers. I get the feeling i'm not that good at the search function, I search under the D2 forum, still having trouble. I find it much easier to search on google, google seems to narrow the search field down a little. Feel free to give me some search tips too
On a side note, Ive seen people replace the bleed T piece with a copper or (maybe) galv' T piece. Would i still be able to put the shop low coolant alarm in it? if so, does anyone know the thread type off hand?
Cheers

More reliable? I don't think so. And neither did the designers. And I love modifying vehicles when it makes sense.
Electrics can't pull more air than a hub fan unless they are big = lots of hp. You need airflow (lots of airflow) for the intercooler and radiator. A set of electric fans will make the engine quieter on startup though. On a petrol it makes sense, on a turbo diesel not so much. If you do go ahead tell us how it goes.
And use a set temperature, not the AC. AC fan also cuts in (I believe) when engine gets too hot.
Don’t do it.
No electric fan will move what the Standard fan does.
And you’ll move load from the fan to the alternator so no benefit.
Electric certainly aren’t more reliable, are less efficient, and add a complexity likely to fail when you need it most.
For the top hose you can buy a very strong Silicone one..
Thanks everyone, appreciate the input. Tombie, I'd also like to know where to get the silicone bleed/T-piece. Cheers

Not cheap but you’ll only do it once!
I wouldn't do an electric fan mod either, just based on the $ factor. A top line electric fan would probably cost more than the viscous/fan combo on a Td5 anyhow.
If you try a cheap alternative, you'll probably end up with a cheapo job that causes you no end of pain.
As for the top hose bleeder thingy, you can get nice quality silicon hose/aluminium bleeder port combos off ebay. Brother got his off ebay. Highly recommended mod on that dreadful plastic bleeder thing!
(V8 one is also plastic, but much stronger than the weeny TD5 bleeder screw).
His came apart(broke into two) trying to undo it to bleed it. small bit fell inwards! took far too much work to get it out before it could do any damage.
search ebay for TD5 silicon coolant hoses and you'll probably find both the built in bleeder types and the metal junction type sets.
They generally come from the UK.
This ebay listing is just the first one I got on a search. He didn't pay close to $700! tho .. about $300 and a bit for his set.
