Well , I am fed up with the expense of my Croma, driveshaft problems, new alternator, brake problems ( normal wear and tear but not helped by the locating the correct part ) , car protection light on and key problem still not resolved and now an over heating problem.
Pulled in a car park last week and noticed the fan was running but temperature gauge was as normal. Thought nothing of it but then when travelling up a steepish hill a few days later under load the needle on the temp gauge was moving into the hot area before returning to normal, also blowing cold air when the dual climate was on maximum heat, happened once more so booked into a garage on the possible assumption of a thermostat problem. Replaced damaged thermostat, broken inside approx. cost £200, but the garage could not get the coolant flowing in the heater matrix , I think that's what he said so the pump is not working or incorrectly. He said a broken fragment could have entered the pump and damaged the pump or impeller so now the only option is a cambelt and water pump change at a cost of approx £300-£350 which is only a rough quote so I think its time for the Croma to go. The temperature needle is mostly showing normal but I assume the fan is working overtime to cool the engine so time to call it a day !
