Q: Car overheating with coolant smell while driving

asked by on

My car keeps overheating once it heats up. There's a coolant smell that comes off the engine and can smell it while driving. Also coolant sounding like it's boiling
My car has an automatic transmission.

It sounds like you have a clogged heater core which will usually be under your dash. You may want to take it off and use a water hose to flush it out. Before flushing it you may want to inspect it to ensure you don’t have any leaks. From what you’ve described it may be leaking.
