ive had overheating problems and now suspect the *electric fan is inoperative, apparently theres a sensor under the inlet manifold which switches the fan on as temp exceeds normal - im guessing this switch may be faulty so its a case of either a new sensor / switch needed.....or bridge the switch so as the fan is on continualy, i favour the latter remedy haveing the fan on permanantly should be less hassle. the *ka is a cheap and generaly reliable motor but mine has had a new head gasket,two new hoses and its still overheating, so i now suspect the electric fan.
