I get a coolant smell in my car when I am in high rpms.. like 5500+rpms. I was thinking maybe I blew a coolant seal... But when I check my coolant it is full (thank god). Is there something else that can cause this? Or is my Seal slowing going.. I recently flushed my radiator and I started noticing it after that.

 

Spill coolant somewhere? Heater core leaking?

 

I changed it last week, and I dout it took that long to dry up.. I am going to check ouit heater core.
