Car Overheating on Freeway No Exit Nearby: What to Do Right Now: Quick Guide Originally published on Tow With The Flow: https://towwiththeflow.com/car-overheating-on-freeway-no-exit-nearby-what-to-do/ ``` Quick Answer: If your temp gauge is in the red and there's no exit, move to the right shoulder immediately and shut the engine off. Do not keep driving hoping to reach an exit. Five minutes of continued driving on an overheated engine can warp the head or seize the block entirely. Get off the road, call for a tow, and let the engine cool before you do anything else. What To Do 1. Move right, now. The moment you see the temperature gauge climb into the red or a warning light fires, signal right and start working toward the shoulder. Do not wait for an exit. The shoulder is a legal and appropriate place to stop in a breakdown. Every additional mile you drive risks permanent engine damage. 2. Turn off the AC, turn on the heat. While you're still moving toward the shoulder, kill the air conditioning immediately. It loads the engine hard. Then turn the heater on full blast. That sounds counterintuitive, but the heater core acts as a second radiator and pulls heat out of the coolant. It buys you a minute or two if you need it. 3. Shut the engine off once stopped. Pull as far right as you safely can, ideally past any white fog line. Shut the engine off. Do not turn it to "accessory" mode and let it idle. A stationary engine without moving airflow through the grille gets hotter, not cooler. Off means off. 4. Get out of the car on the passenger side. Step over the guardrail if one is present. Freeway shoulders are dangerous. Standing next to your car on the traffic side while waiting for help is how people get killed. If you have passengers, move everyone away from the vehicle toward the embankment. See the guidance in car broke down on interstate in the middle of nowhere for more on managing a highway breakdown safely. 5. Do not open the radiator cap. The cooling system is pressurized. If the engine just overheated, the coolant inside is still near boiling. Opening that cap sprays scalding fluid. Wait at minimum 30 to 45 minutes before you touch anything under the hood. 6. Call for a tow. This is not a situation to nurse the car to the next exit. If the gauge hit red, you may already have a blown head gasket, cracked block, or seized engine. Adding coolant and limping off does not fix that. It makes the diagnosis harder and the repair more expensive. Call a tow truck and let a shop assess what happened. If you're unsure what you'll pay out of pocket, car broke down on highway in Denver covers costs and who to call, and the numbers are similar nationwide for reference. 7. If you have coolant and the engine has fully cooled, check the reservoir. Only do this after 30 to 45 minutes with a cool-to-the-touch radiator cap. If the overflow reservoir is empty and you have pre-mixed coolant in the car, add it slowly. This does not solve the underlying problem, but it may allow a short, careful drive to the nearest exit if you absolutely cannot wait for a tow. Watch the gauge the entire time. If it starts climbing again, pull over immediately. 8. Turn on hazards and make yourself visible. Hazard lights on, hood up if you can do it safely from the passenger side. If you have road flares or reflective triangles, place them 100 to 200 feet behind the car. This matters especially at night or in low-visibility conditions. !mechanic engine coolant Photo: Pexels What It Might Cost A tow from a freeway will typically run $75 to $150 for the hookup fee plus $3 to $7 per mile depending on your location. If your engine actually seized, you're looking at $3,000 to $5,000 or more for a rebuild or replacement. Stopping immediately is always cheaper than continuing to drive. Check your insurance policy or roadside assistance membership before you call, since many plans cover freeway tows at no out-of-pocket cost. !tow truck highway Photo: Pexels Stay Safe
- Stay behind a guardrail, not next to the car door - Keep your phone with you, not in the car - Do not accept rides from strangers. Wait for help - If it's extremely hot outside, crack a window and stay in the car only if you are far enough from traffic lanes - At night, stay low and visible. A reflective vest or even a white shirt helps - If smoke is coming from under the hood, increase your distance from the vehicle. For a car that is actively smoking, car smoking under hood on highway covers when it becomes a fire risk Need roadside help? Visit Tow With The Flow for real answers when your car breaks down.
