If your temperature gauge is climbing, an overheating warning appears, coolant is leaking or steam is coming from under the hood, continuing to drive may make the problem significantly worse.
Whether you’re driving near Reston Parkway, Wiehle Avenue, Sunrise Valley Drive, Sunset Hills Road, Fairfax County Parkway or the Dulles Toll Road, an overheating vehicle should be taken seriously.
If the engine continues getting hotter, safely get out of traffic and stop the vehicle. Towing the vehicle to a repair facility may be much safer than trying to drive farther with an overheated engine.

If your vehicle is actively overheating, towing is usually the safer choice than continuing to drive.
Continuing to drive an overheated engine can potentially cause severe and expensive engine damage. A tow to a nearby Reston-area repair facility can help avoid putting additional load and heat on the engine.
Get Help With an Overheating CarAnswer five quick questions to see a general recommendation. This is guidance only — not a diagnosis.
Safely get away from active traffic and stop the vehicle if you can do so without risk. Arrange assistance rather than continuing to drive.
You didn’t report the most serious warning signs, but overheating should never be ignored. Have the cooling system checked before returning to normal driving — and pull over and stop if the temperature climbs again.
This tool offers general guidance for drivers, not a mechanical diagnosis. Always prioritize your personal safety and follow local traffic laws.
Where you overheat can change what you should do next. Find your road below.
Reston Parkway is one of the primary north-south routes through Reston.
If your temperature warning appears while driving along Reston Parkway, avoid trying to push the vehicle several more miles simply to reach your destination.
Find a safe place away from moving traffic and arrange assistance if the engine continues overheating.
Wiehle Avenue connects major residential, commercial and transit areas around Reston and crosses the Dulles Toll Road corridor.
If your vehicle begins overheating near Wiehle Avenue or the Wiehle-Reston East area, safely pull off the roadway when possible and avoid continuing to drive an engine that remains excessively hot.
Sunrise Valley Drive is a major east-west Reston corridor south of the Dulles Toll Road.
If you experience engine overheating along Sunrise Valley Drive, stop driving if the temperature continues climbing or steam or coolant leakage becomes visible.
Sunset Hills Road runs through major commercial and employment areas north of the Dulles Toll Road.
Drivers experiencing overheating should avoid continuing toward another destination simply because it appears nearby.
Even short-distance driving while severely overheated can potentially cause additional engine damage.
If your vehicle begins overheating while traveling on Fairfax County Parkway near Reston, roadway safety comes first.
Use hazard lights when appropriate, move away from active travel lanes if it is safe to do so, and arrange assistance.
Higher-speed roads require extra caution.
If your car overheats on or near Route 267, do not attempt roadside repairs in a dangerous location.
Move to a safe area when possible and contact towing or emergency assistance as appropriate.

Call for a Reston TowFollow these steps in order. Your safety comes before the vehicle — every time.
If the temperature continues climbing toward the red area, take the warning seriously.
Move toward a safe parking area, shoulder or exit when possible. Do not make sudden or unsafe lane changes simply to stop the vehicle.
Once safely stopped, turn off the engine if it is overheating.
Cooling systems can remain extremely hot and pressurized. Opening the cap can release boiling coolant or steam and cause severe burns.
If the vehicle continues overheating, has a coolant leak, produces steam or repeatedly triggers an overheating warning, arrange towing rather than continuing to drive.
Safety Warning
An overheating cooling system can contain extremely hot, pressurized coolant.
Removing the radiator or coolant reservoir cap while the system is hot can release coolant or steam suddenly.
Wait until the vehicle has cooled sufficiently and follow the manufacturer’s instructions.
If you are stranded somewhere unsafe, prioritize your personal safety instead of attempting roadside repairs.
Several different failures can cause an engine to overheat. These are common possibilities, not a diagnosis of your specific vehicle.
Insufficient coolant can prevent the cooling system from properly controlling engine temperature.
A leak can occur in a hose, radiator, reservoir, water pump or another cooling-system component.
A malfunctioning thermostat can prevent proper coolant circulation.
Leaks, blockages or damage can reduce the radiator’s ability to dissipate heat.
Cooling fans are particularly important when the vehicle is stopped or traveling at lower speeds.
The water pump helps circulate coolant through the engine.
On certain vehicles, a failed belt can interfere with the water pump or other engine accessories.
A head-gasket problem can cause or result from serious overheating.
Onyx Auto Towing does not diagnose mechanical problems. A qualified repair facility can identify the actual cause of your overheating issue. Our job is to get your vehicle there safely.
Some cooling-system problems become easier to notice during slow-moving or stop-and-go driving because the vehicle receives less natural airflow through the radiator.
Areas around major Reston intersections and the Dulles Corridor can experience significant traffic.
If your vehicle runs hotter while sitting in traffic but cools down while moving, a mechanic should inspect the cooling system.
Use this quick reference to match your symptoms with general guidance.
There is no universally safe number of miles that an actively overheating vehicle can continue driving. When the engine remains excessively hot, additional driving can increase the risk of damage.
