Hey guys weather is getting cold here were i'm at. I start using heater in the car but every time heater is on i smell coolant inside the car.I check all over the engine ever coolant hose but did no fine any leak. Has anyone ever have this issue? any place that i miss to check for this issue?

 

possible heater core leak. is your passanger side carpet damp?

 

No passanger side is not wet or damp at all.

 

It may be a small leak then. That's the only componant that contains coolant inside the cabin. It's a pain to replace, so if you don't actually feel anything wet, you can probably put it off for a while, but it's not going to get any better over time. Also check your coolant level to see if it's stable.

 

Do you smell coolant if the heat is off but the fan is on? If so, it may be coming from the engine bay and not the heater.

 

Did not try that yet will do and see if i still can smell it.
