D3 2.7 V6 alternator replacement.

[Brendan1477]

Hi Guys,

Im just wondering how much people have paid to have the alternator replaced and which brand is the best option to go with, Ive had a vast difference in price. I'm based in Perth.
Cheers in advanced

There is one on gumtree in Perth at the moment. It may fit your 2.7l.

The genuine Denso should range in price between $550 to $1100 in Australia and 2/3 the price from the UK. Ashdown Ingram sell a OEX knockoff (made in Taiwan) for about $550 - is convenient as they usually carry stock and is a quality item.

The LR time to change the alternator is 45mins but I took about 90 mins but you will need to buy the fan tool from a tool shop for about $30.

It's for the 3litre unfortunately, but thank you

Not quite. There are a variety of ways to hold the fan hub using objects in your tool box. A long socket extension and socket between one of the fan clutch bolt heads to something on the engine. Just know that it has reversed thread and undoes in the opposite way. A solid tap with a big spanner on fan once you have braked the hub should be all it needs.

There is a good how-to on Disco3.co.uk and had also been referenced here in another thread. A ratchet spanner for the alternator bolts probably makes the biggest difference. I did without and it just makes it a lot slower.

P.S. I have my original 160k km alternator still working perfectly in a box in metro Perth free to a good home if it helps anyone.

Yes there are a variety of ways - but easiest is to get the spanner - cheap and available at any decent tool store. I tried the method you described and it did not work - the little bolts just undid so I had to borrow a car and then go and get the spanner half way through the job - wasting time doing the job.

When you assemble the bits you need to do the job just buy the spanner - also fits a number of other LR engines - also used it on my 4.6 fan.

I tried a couple of other brands, they promptly failed down the track.
I only use and keep in stock the Denso for both D3 and D4.
Quite often if the alternator fails dont be surprised if the battery fails not so long after, and also vise versa.

I had the same problem 2 weeks after the alternator died so did the battery
So undo the nut i made a brace bit of flat on a length of rod that bolted onto the pulley and locked so the nut would come off.

Certainly not worth the pain, Denso is my choice too...

I attach a couple of pics for a quick fix (crude) hub tool I made because I can't just go down road and buy one.
I used a bit of 3-4mm flat bar with a cut out (see red lines, welded additional metal after cut out), and then welded a couple of tags along edge to make the attached shape.
Just so it would lock over the nuts on hub while I "cracked" the fan off.
I'm a bit slow, so took about an hour to make.
I made up a cardboard template first and used that as a guide for my pattern.
Tool needs a bit of a bend in it to be able to slide in easily and lock on two nuts to hold.
Was able to change out a water pump on roadside using the "tool", so good to have one in the toolbox when travelling.

I just got a combination of socket extensions the right length. With a socket on one end bracing on a nut head and the drive end of the socket resting against something firm on the engine. A piece of timber would do same.

Once braced. I did not find the fan needed much persuading at all with a large adjustable spanner on the fan nut.

[DiscoJeffster]

I just did the bush mechanic trick of a sharp crack with a cold chisel on the edge of the fan nut to shock it loose. Works every time though I admit does leave a small mark on the edge of the nut. Await the flaming from the self righteous members [emoji6]

Hi All,
Could someone describe or post a pic (although for some reason I find pics impossible to view recently) of this 'fan tool'?

Might take one with me to Cape York

It is basically a long very thin open ended spanner. It is about 14" long, is only a few mm thick and I think is 36mm (or is it 32mm) - I just cannot find mine at the moment to take a pic.

I bought mine from Total Tools for about $30 - they are marketed as a Ford Fan Hub Spanner - there are a few different sizes.
