Hey guys, so here goes my second post. I have a 1995 e34 with only 80k on the clock. It’s been getting colder out and I notice when I turn the heat on it smells like something sweet and or a burning smell. And I do tend to get the fog on the windows. The car does smoke a little (white) on warm up but nothing bad at all due to the temperature & then goes away once the engine is warm. The previous owner had a new radiator installed in 2007 and I have noticed a small radiator drop in fluid say every 500miles. There are NO signs of leaking anywhere and before I got the car the head gasket was replaced. So im thinking I need a new heater core but just wanted to ask some advise since I hear it’s a pain in the ass to do and cost a lot if I take it to the dealer to have them do it. Any thoughts or suggestions?? Thanks :-D
