Got the Peugeot 106 XND out of the garage (it's been SORNED for the last 6 months) and replaced the battery, checked the oil and the water. The water was very low so replaced that with a 1:1 mix of coolant to water.
On starting up the car, the temperature warning light stays on and the engine fan doesn't start. The heater will blow hot air. The actual temperature of the water gets very hot very quickly (there doesn't seem to be any leaks). Any ideas? Could an air lock be the cause of the problem?
