It would be really helpful to know which model and year your Rover is.

 

1997 Discovery SE7

 

There are tons of different approaches to bleeding coolant. The basics include...
1. Fill radiator fully and reservoir to just over the fill line
2. Park truck so that passenger front is higher than rear. The more the incline the better.
3. Run truck at 2500 RPM with the heater on full blast.
4. when hot air blows from vents, shut it down and check fluid levels. Add as needed.
5. Take a spin around the block.
6. check fluid level. add as needed.

BTW, best to post in the D1 section. You'll get more eyeballs on your posts.
