Hi everybody, we are new here. We are a Brazilian couple in a round the world honeymoon in our Land Rover 300tdi. If somebody can help us, we are facing a strange issue. The engine gets very cold when we go from 3.500m to 3.200m for instance. Every time we go to lower altitude. Is it a problem to drive with the engine very cold? (in the blue marker) Thanks! Ah, just to introduce our machine is this one, in Bolivia 2 months ago. If anybody want to check, www.facebook.com/daytrippersbr and www.daytrippers.com.br, we write both in portuguese and english!
