Thread: TDV8 Alternator replacement

OK, apart from a bit of claret from a sharp hose clamp, (See gore pic below ) it took 2 hours to remove. It isn't particularly difficult, just fiddly. I would say it is a DIY if you have some patience and some 1/4"drive long reach bars and socket set, a pair of hose spring clip removal pliers, and some band aids .

Firstly, remove the under skirt and all engine undercovers, the airbox, the coolant expansion bottle, and either drain the coolant if you are changing it out, or plug the pipes to prevent loss. unclip the top of the shroud, remove and unplug the fan, (It is a left hand thread)Then unscrew the power steer (I think that is what it is..) cooler from the bottom of the shroud and unbolt the 6 small screws with hex heads holding the shroud to the rad, and the turbo inlet pipework from the passenger side of the shroud. withdraw the shroud upward. Remove accessory belt and check tensioner and idlers; these were ALL in dire need of replacement, this vehicle has 92,000km up.

The main battery wire connection is on the outer edge of the alternator, covered with a red rubber boot. It is hard to see but after the 3 bolts and the front stiffener bracket for the alternator mounting are removed and the alternator is free to drop down, it can be rotated slightly to access this 13mm nut. Undo and remove the main battery wire, then pull alternator forwards enough to remove the plug at the back, LR are thoughtful enough to allow excess wire length so this can be done

You will have to jiggle and wiggle it a bit, and pull some small coolant hoses out of the way but the alternator will come out easily.

Note:

Firstly, A big thanks to Sniegy, a quick call to him after I discovered my RAVE disc got damaged and wouldnt read, had him help me out in no time, So thanks Pete!!

Secondly, I took off the drivers wheel and inner guard liner, even though apparently it looks like you don't need to do it at first glance, you do to get a look at things and it also helps with light so you can see better

Thirdly, be very careful of these spring clips holding the hoses on, I sliced and tore my hand very easily on one, while blindly undoing the main battery lead from the side of the alternator.

All in all it wasn't as bad as I was lead to believe, and refitting everything when the new Alternator turns up should go without a hitch, except I am thinking the main lead reconnection and starting the nut maybe a bit of a pain...

Part numbers;
Alternator YLE500340 (Supercedes apparently to LRO26344)
Main drive belt PQS500430
Belt tensioner PQG500160
Idler, small, 2 required PQH500090
Idler, larger, 1 required PQH500080

Enjoy

What coolant did you get? I use Holden Delco red. Same stuff as LR, but cheaper.
