I recently noticed that the fan seemed to be increasingly audible, above the radio at some times! The engine management (yellow, car with bolt) light then started to appear intermittently, and then the thermostat light (red, thermometer) started flashing. So I took it to the Vauxhall dealership (out of warranty) and after their diagnostic check they said that itís the antifreeze and thermostat housing and would cost over £200 to fix!
Is this something I could remedy myself, does it need a new thermostat? Iíve just had a look at the coolant level and it is a little low, but Iíve noticed a leak on the 2nd hose (I think the one above comes from the fan, does one below go to the thermo?)
