I have read the recent threads about Disco's overheating. Well, the first time mine did it I was towing a horse trailer with a large horse on board. The engine temp went up and steam came out from under the bonnet. I lifted the bonnet and saw water and coolant coming out of the reservoir. After topping up I managed to limp home. Whilst the engine was overheating I noticed there was no heat coming from the cabin heaters. I had the thermostat changed and it seemed to solve the problem but then I noticed the engine overheating and no cabin heater whilst driving without towing. Suddenly warm air started to flood the cabin and the heater switch dropped straight down to normal. Any ideas?
