so sometimes when im in heavy traffic.. or in a busy parking lot.. my car starts heating up.. never goes past half the meter... usually its on like 1/4.. but when it gets to 1/2 it starts smelling like antifreeze.. my neighbor told me it could be leaking to the inside.... what do you guys think?

 

probably leaking. i had alot of temperature problems with my car. intake gaskets, water pump, hoses. you could only smell the antifreeze when i was idling and would let itheat up to a little over half. could just be a hose, if you're lucky. check all the clamps
