i bought my rx7 not to long ago. recently ive noticed that i smell coolant while driving it. today when i parked i noticed smoke coming through the air vents. i smelled it and it smelled like coolant. i smelled my exhuast and i didnt smell coolant so im almost certain that is the heater core or hoses. also when i let the clutch out in neutral i hear and sort of whiring noise.

 

does your exhaust smell kinda sweet..?

 

you're pretty spot on witht the heater core, its a pain in the *** to get to but it'll need to be fix. the whiring noise is the throw out bearing.

 

if you're sure its coolant coming from the vents then the only real possibility is a failed heater core.

 

how much is it to get a throwout bearing put in. i could do it but im lazy lol.
