elbow grease is what you need.they get tight with the heating and cooling.
try running the engine to warm it a bit and ease removal

What tool are you using?
A proper lambda socket (with wire slot) or a large (adjustable) spanner.
My advice is if using a socket then use a long breaker bar handle on it to give leaverage. And if using an adjustable spanner then use a good quality one as these really do make a difference over cheap stuff. My teng spanner will do it no probs, where as my cheap chinese crap one used to open up at the slightest of pressure and start to round the hex off.

A normal spanner will do, if you can get one in there. Once it starts to shift, squirt some WD40 into the thread.

Don't fix at the side of the road.. just drive to the shops, and back to your house, then have a go. You don't want it tooo hot either or you'll burn yourself.

Penetrating oil will help, and a big spanner or deep socket.

think its 19mm from memory?

Try heat from a blow torch as well, or do it up a bit before undoing it.
