Hello! I drive a 2002 mini one. I LOVE IT SO MUCH! I took it for an MOT 2nd may passed flying colours no advisories, but recwntly its losing coolant fast so needs a new water pump. I've took it to a mechanic who has advised I need a whole new drive belt, tensioner, cylinder head, head gasket and coolant system (expensive job) my question is though I've had no warning lights whilst driving, I've had a temperature gauge go right up but then settle n be fine. The oil tap and the dip stock isnt milky at all n there is no smoke blowing out of either the exhaust nor the bonnet? Should I seek a 2nd opinion?
Any help or advise would be amazing (i only passed my test recently n this really is my dream car i dont want to have to loose it)
