You can try, but dont hold your breath, parts like that are the first to go off "breakers".

 

Definitely agreed there. When I went looking for a bunch of new interior odds and ends for my rig I went to 4 different yards in my area. Found ONE rover, and it was completely stripped. But still, it couldn't hurt to look. Other than a few grand in gas [:@]

 

There just are not that many Rovers on the road, compared to other cars, so there are few that get totalled and wind up in junk yards. And because these trucks are expensive the totalled ones will be repaired and then sold with a salvage title.
The one that you do find in a junk yard will have been completly stripped of all the intierior bits and the under the hood parts that are prone to breakage by the owner/quick lube.
Basically you need to follow one from the accident scene to the junk yard to get any parts off it.
Just one of the perks of owning a unique vehicle.

 

To drain the block, I'm assuming that one must remove the plastic covers underneath, then remove the drain plugs from the left and right of the cylinder block? Also disconnect the bottom hose from the radiator and the top hose from the the termostate? Finally, when flushing, where should I run the water into the radiator?

 

All you need to do is remove the lower radiator hose from the bottom of the radiator, remove the thermostat and run your garden hose through the engine block and then through the radiator. With the lower hose off still.
Leave the thermostat out and replace both radiator hoses. Fill the system with water, start the truck and turn on the heater.
After 10 mins of idleing shut the truck back off, go have lunch and then remove your lower radiator hose again, install your new thermostat, replace the hoses, fill with your new coolant, bleed the air out of the system and you are good to go.

Buy removing the lower radiator hose you will drain 98% of the coolant out of the system.
