Hello my extended family community I having a problem with my 2008 Range Rover Sport. It's been over heating and don't know why? I've changed the radiator.. Reservoir tank...water pump.. thermostat...and sensor( not the hoses)and it's still over heating. It takes about 10-15 idle or driving and I'm just puzzled on what it is or could be. Please my family of genius's Any suggestion or theories would be greatly appreciated.
