That's considered a great range of temperatures. Some people strive or lower, most are happy with that.

If you REALLY want to bring your temps down, I'd suggest swapping to an inline thermostat - the style of cooling system that comes stock in rovers is incredibly anachronistic. Swap to an inline and you can ensure coolant flow goes through the radiator and keeps the entire engine cool. I also have an electric fan installed in the grill in mine, and I run temps from about 175 on highway, to 185, maybe 190ish on idle
190 to 200 is pretty decent, as long as it doesn't get above 205ish, but it is still pretty objectively terrible, especially for the Rover aluminum block so susceptible to overheats.
Try installing an electric fan first, if you're still not happy and have the extra time + money, throw an inline in that baby and enjoy much cooler Rover temps 8)

ditto on the inline thermostat. IMHO one of the best mods you can do to these trucks.
I live in Scottsdale AZ where is is hotter than Satan's outhouse. Can still run 190-195F in the summer with the AC on.
If you're in a really cold climate it has a few drawbacks, but I still think its going to be your best option no matter what.
I've done it to my past 4 rovers. All good results.

I'm intrigued by the electric fan idea. Could someone detail the parts needed for that set-up. If I stay with a fan clutch, is the 02 fan better than the 04 fan? I have an 04. I will probably add a sandwich oil cooler before next summer as well. The plan s 180 deg t stat, new water pump, rebuild oil pump and replace fan clutch, add oil cooler. I may even add hood vents to get rid of the heat.
Thank you.
Thank you.
