i got got home and heard a hissing noise from the engine, i saw some smoke and a bit of coolant, what can it be?
Coolant escaping from the expansion tank or hose. Replace ASAP before you overheat causing more damage......http://forum.e46fanatics.com/showthread.php?t=914109
Tom, this the expansion tank the same as the resevior? The hissing was coming from the thermostat area.
