I know I need to remove the intake manifold but do I take the throttle body off first? Also is there any special tools that I need to take the intake off? About how many hours should I expect to do this job? thanks in advance. It's an 01 S60 non turbo.

 

You can leave the throttle body on the intake.
You should need to get a fuel line disconnect tool to disconnect the fuel line.

If this is your first time I would say atleast half a day to do the job.

 

Really? In the UK Haynes Manual for the S60, it says you can remove it by removing the alternator but leaving the intake on. True???

 

I have never done or tried it that way.
