first off i bypassed the heatercore and connected the 2 ends.. but anyways. the radiator light was on so i added some coolant.. then i was driving and all of a sudden the temperature went all the way for up for like 1 minute and i smelled coolant..i stopped and then there was coolant dripping from a few spots and it was smoking from the splashed coolant.looked to come from the over flow spot. i put some more coolant in because the light was on again.. and now its fine and nothing happens.. i also drove it a few times after i bypassed the heatercore and it didnt do that .. any ideas.. bypassed because my windshield was getting a slight fog which was form the heatercore i believe.. which means coolant leak there..car seems to be wierd with coolant.. also i burped it 2 times.. but still seems to have a little air in itbeing that it rises to hot quick then drops right down instantly..
