Quick Answer: Steam coming from your radiator means your engine is overheating from coolant loss. Stop driving immediately or you’ll cause expensive engine damage. Pull over safely, turn off the engine, and call for a tow. Local tows typically cost $75-150.
What To Do
Pull over immediately at the first safe spot. Don’t try to drive “just a little further.”
Turn off the engine and put on hazard lights. Leave the hood closed for now.
Wait 30 minutes minimum before opening the hood. Steam and hot coolant can cause severe burns.
Check coolant level once cool. Look at the overflow reservoir first, then the radiator cap if you can see it.
Look for obvious leaks under the car and around hose connections. Green, orange, or pink fluid means coolant.
Call for a tow if coolant is low or you see active leaking. Don’t add water and drive unless it’s a true emergency.
If you must add coolant temporarily, use only water if that’s all you have. Let the engine cool completely first.
