robwob88 Posted March 20, 2014 Share Posted March 20, 2014 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. Quote Link to post Share on other sites
Jim* Posted March 20, 2014 Share Posted March 20, 2014 Could just be air in the system if it was dry then you filled it up it would of needed the bleeding, the question is why was it dry Quote Link to post Share on other sites
robwob88 Posted March 20, 2014 Author Share Posted March 20, 2014 That's baffled me too. The oil cap wasn't as tight as what it could of been and there was a ted on top of the engine. Before I set off I checked and there was plenty of oil in. I've not noticed any wet patches underneath or signs of oil and surely it cant of burnt all its oil in 170 miles. It only used just over half a tank of fuel! Baffled. Im going to change the stat on it and flush out all fluids and start a fresh. Quote Link to post Share on other sites

symoep91 Posted March 21, 2014 Share Posted March 21, 2014 U bleed the radiator fully? Quote Link to post Share on other sites
robwob88 Posted March 21, 2014 Author Share Posted March 21, 2014 No...I just filled it up and it started bubbling. Today when I checked through the rad cap, it was empty again. Is there a bleed valve to make things easier? Tomorrow I'm taking it into work and one of the techs is going to get it up on the ramp and give it a good once over. How easy are the thermostats to change on them? Quote Link to post Share on other sites
Jim* Posted March 21, 2014 Share Posted March 21, 2014 2 bolts couldn't be much easier Quote Link to post Share on other sites

seab Posted March 22, 2014 Share Posted March 22, 2014 I've had dodgy thermostats and I've never had the temp shoot up. Normally the opposite won't get warm air, and temp gauge doesn't rise Quote Link to post Share on other sites
