It's been a while, but from memory, I took the locking plate off.
And I don't think there is a enough room to get a ratchet in there, so I used a breaker bar.
The breaker bar is shallow enough with a socket.
The socket is put in place first and then the bar is inserted into the socket.
I think there is enough room just to get the socket off and on to rotate the engine once the tool is in place.
I have done it to time the ignition _ I know I have, and I certainly would have remembered if had to take the rad out.
I did from down below on my side with the car jacked up a bit.

It's not a good practice to turn any engine in the direction it doesn't normally run (mainly to protect valve gear tensioners and possibly the transmission). Due to clockwise depending on which direction you are facing, I'll say turn it so the exhaust side of the crank is going down and carb side up. That said, a few degrees in the wrong direction shouldn't harm an XK.

Generally engines with timing chains that use hydraulic tensioners should not be rotated counter-clock-wise.
Standing at the front of the car looking at the front wind screen, the engine will be running clock-wise.
Gear driven cam shafts and cam shafts driven with timing chains with no tensioners _ it really wouldn't matter.

Quote "Really difficult. On other cars you can get a socket on the front pulley nut, remove the spark plugs and rotate the engine using a ratchet on the socket. With the Jaguar and I can only speak of my S Type there is just no room between the engine and the back of the radiator to get anything in there." unquote

Nice tool and well thought out but it would still not work on the S type. The S type has a shroud around the fan which stops you getting anything on the bottom pulley nut. You could I suppose bend the shroud to one side but it is made of a fibreglass material and I would be afraid of breaking it.
