Hi there,
About time I introduced myself. Brian Sexton, I am originaly from Ireland but live in Sweden where, like some other contributors to this forum, I work for that car Company in Gothenburg. Yes, the ones that make nice safe family cars or, as they say in the movies "There're boxy but there're good!" I work on Engine Management Systems, which is a lot of fun.
I am on my 2nd GTV6, the present one I purchased 2 years ago and have been doing some small jobs on it. I recently got my hands on a 3.0L 75 and took it to the scrap yard last week after stripping it of everything useful. The winter project is to renovate the 3.0L engine and put it into the GTV6.
Anyone have any tips on removing the front pulley nut ?? Is it just brute force and lots of torque ??

Brian welcome aboard ! For the front pully nut I find that a good sharp wack is usefull in order to break the bond between the nut and the crank.What I did was place a long piece of angle iron between the flywheel studs and my concrete floor to prevent rotation.I then used by sturdy rachet on the nut and gave it a good wack with a rubber mallet.Worked for me hopefully it will for you.

Well if brute force won't work... You can drill two holes in opposite positions in the nut and seperate it with a punch. The nut cracks and the pulley comes of. I've always have done it this way since brute force didn't work. Takes me 10 minutes now to get the pulley off (and yes I do always try first with the impact gun.....).
You will have to buy a new nut, but they don't cost much and it's good for peace of mind to use a new one.

Welcome Brian,
Regarding the tight pulley nut. I see we have had a variety of suggestions all of which should help. Naturally vibration prior to or during the rotation is very usefull.
If for some reason a previous assembly has used a thread lock chemical then this technique will often not help. The suggestion by Dennis of course will in all circumstances.
My personal choice is to heat the nut up sufficiently to burn out the thread lock chemical and cause a break in the bond by expansion. After that even a relativley moderate impact wrench will remove it.
PM me if you want to know about the heating technique.
