Son wants to buy a 2001 Jaguar which hasn't run in the last two years.
I would like to try turning the engine over by hand, using a breaker bar and socket, but can't see the drive shaft/pulley nut to know what size it is for the proper socket I need.
Forgot to mention that the engine is Supercharged, if that makes a difference.

Any help would be appreciated.

Thanks

 

I believe it is 24mm.

 

+1 on 24mm bolt size.

Remember to only rotate the engine in a clock direction when viewed from the front of the vehicle.

 

Norri and NBCat,

Thanks Again
Chuck
