The cooling fan on my 14 yr old Zafira, the family tank worth about 500 quid, began running continuously, then nearly home on a 280 mile run the engine overheated.
Three visits to the Vauxhall main dealer and their sophisticated diagnostic machine resulted in replacement of the cooling fan motor (twice), fan control module, MAFF and Lambda sensors, thermostat, water pump, all hoses, much labour and inconvenience and bills for £1600, but still the fan ran continuously. They gave up after suggesting trying replacement of the very expensive ECU.
Before scrapping it and as a last resort I took it to my local lock-up chap. He opened the bonnet and whilst leaning on the front of the grille noticed that one side of the radiator was really hot whilst the other side was cool. He flushed the radiator. Loads of sludge emerged. He refilled the system and charged me 20 quid. It has run perfectly ever since.
In future I'll take it to the hands-on chap with an oily rag.
