Owned 2002 Range Rover Vogue for 12 years. Cooling system probs. Blown three expansion tanks. Had hydrocarbon test which was negative. So going back to basics, replacing expansion tank and thermostat. Need to know how to bleed the cooling system when replacing expansion tank. Need to know how to fit new thermostat (electronic). Last but not least, where can I get a workshop manual for my Vogue? Thank you.
