this is a quick guide for the TDv6 alternator. for the torque settings refer to the Gtr files

Firstly thanks to Club Member mzplc without his help I wouldn't have got the bonnet up but thats a different story.

firstly get the battery terminals off and make it safe


we also got the plates off the bottom of the car this wouldn't have been necessary if I hadn't found my self in a predicament of not being able to open the doors but it is useful to do if you drop a tool or a bolt.

remove the fan cowling and intercooler hose



the fan needs to be removed. There is a special tool to lock the fan. we were able to undo it by putting a spanner on (think its 36mm but I have a big adjustable) and giving it a sharp blow with a hammer. it is a left hand thread. unplug all the wiring.

we then took the air filter and air box off to give a bit of extra space once the top is off and the one torx screw is removed the rest comes out with a good pull




this might not be required but it only takes a few minuets and extra elbow room is always handy.

the belt tensioner accepts a 1/4 drive head so you can take the tension off the belt



pull back the insulator cover then remove the wiring harness. Note on refitting I decided it was easer to put this back on before I bolted the alternator on as it has a couple of lugs that have to slot in and when in position I felt this would be difficult to achieve, it also allowed me to make sure I didn't trap the insulator sleeve





undo the 3 bolts and unplug the connector at the back of the alternator. An additional note I had to use a short torque wrench to get to the bolts and it was easer to do them with a ratchet spanner than a socket set.

put it all back together and check the voltage with the engine running


I would recommend you wear long sleeves as your arms will be rubbing on the inner edges of the wings and gloves are always a good thing

I didn't bother taking the air box out, but agree it would have made access a little easier.

I found putting the battery cable back on the alternator straight forward when in situ as the lug keeps it in the right position.

Cable on after refitting the alternator is definitely the way to do it. I also didn't remove the air box, just the fan.

I can open the bonnet but that's about it.

I just found it easy to put the cable on while i could see it ... But as ever more than one way to do it.... Del i suspect even you could do this job snot hard imho

Nah, I'm deffo not techie enough.

Just one point on this guide, the tensioner is a 3/8" Hole, not a 1/4" Hole

I've taken mine out using steps similar to those here, we shall see tomorrow how easy it goes back in again!

Keep us posted

I'm sure you'll be fine.

you will be fine
