Gonna be putting a new radiator in this weekend (97 XJ), and was wondering if it would be a good idea to drain the block as well? Anything special I should note? ( I have put many radiators in befor just never one in an XJ)

Piece of cake install with your said experience. A complete fluid change wouldn't be a bad idea at all. Don't forget to flush the heater core while you're at it. Both hoses are right up top so it's simple to flush in both directions using an ordinary garden hose.
Might want to pick up a little ATF for what you'll lose in the radiator/cooler.

Totally agree. I didn't do that the last time, and end up with my nice new clear coolant mixed with the crapola from the heater core. Went from nice pale green to crap brown green.

So just pull off both heater hoses, and run water through one till clear water comes out the other one and vise versa? Thanks guys.

One more thing. If I drain the block, how can I refill it. The thermostat will be closed so I can't just pour in coolant through the top hose correct? If I remove the housing and therm. I can't pour anything in because its horizontal? Forgive the stupidity, but I must be missing something.

The OEM Thermostat has a little hole to let the air out.
Point it to 12 o'clock.
