Hi guys. Im a newby here so I apologise if I sound abit thick. Yesterday I picked up my 1st glanza. 170 miles into the maiden voyage home I noticed that all of a sudden the temp dropped on the heater to blowing cold air on any setting and the temp guage shot straight up to almost very top. As soon as I noticed I immediately pulled over and switched the engine off. The recovery guy told me "its probably just your thermostat as they are shit on these" however, when I've come to check it today, I've noticed there's hardly any oil in the engine and the radiator was bone dry. I've topped up the oil and filled the radiator and fired it up without the cap on the radiator. At idle its fine but under load it bubbles straight away. Could this be a blown head gasket? That's the only sign there is so far. No mayo, no white smoke or signs of water out of the exhaust, just bubbles. I've not done a compression test yet or a sniff check. What's your thoughts? What do I need to look for and where? Any help is greatly appreciated. Rob.
