burning smell

over the past 2 weeks when I start my car up and let it warm up and turn my heat on I smell a burning sent coming from my vents,anybody have any ideas on what the problem could be? any comments would be appreciated

Possibly the heater core leaking coolant? Oil dripping on the front header from the valve cover?

thanks,never thought of that,my low coolant light has been going on and off n tha morning time and I think I might have a oil leak anyway

No problem! Thank me with the ''Thanks'' button.

I would say it is a coolant leak. I had that smell when I forgot to tighten up my thermostat housing after I did my lim gaskets

it might be time to do that LIM gasket, We all have to do it, even though we don't want too!!!!!! Mine did the same thing till I tracked it to the LIM.good luck.

well if it is the LIM then i'll just wait till I do my ssm90 kit bcuz then it wil have 2 be replaced anyway

If you have an older engine, like 01 or something, If you used conventional, or if the previous owner used conventional, and you change to synthetic, the sealants might have eroded away and were replaced by just rings of 'dried oil' if you will. When you switch to synthetic it actually cleans out these rings, leaving a gap and causing a small oil leek. I sadly took forever to get the dang things replaced becuase labor is a pain in the butt. The previous owner said she used synthetic, but apparently, she didnt -.o
