  1. interestingly enough I had my cdi overheat on me in a very short time on a cold -29 day in Winnipeg, however has now happened for a third time. Cold started the engine not plugged in barely started. pheeww i idled the engine for 1 minute then proceeded to work and noticed i received my first bubble of heat rather quick only after 2 kms or maybe 3 minutes total engine run time. then received my 2nd bubble after another 2 kms.and only a minute later or 1 km i got my third bubble that i never saw once in winter especially one of our coldest days i knew there was something wrong aswell noticed no output from heater matrix as my windows refused to defrost with cold air. i then got my fourth bubble and knew i was overheating. so i pulled over and let it cool down. Now here is my question. if the cooling system is always circulating coolant though heater matrix regardless of the thermostat being open or closed. then why did i overheat with no output from heater? is my Canadian model smart cooling system run differently than what others have described on club smart ? on a day -26 and warmer i have never had this issue occur on a warmer day. and i will start to receive reasonable heat usually just before my second bubble shows on the cluster. my only possible explanations are my heater matrix flow is controlled by thermostat and i am having occasional issue with thermostat sticking closed. and my water pump has to be still in good condition if on slightly warmer days (-24) i get heat as normal. and i hear no belts squeal. so coolant flow through system should be sufficient. i am stumped. any other suggestions? or explanations?
