Why Your Car May Be Overheating
Cars tend to overheat in extremely hot temperatures. Even a well-tuned car can overheat, which is considered rare in modern vehicles. Under normal weather conditions, one of the following could be responsible for your vehicle overheating in traffic:
- Low levels of water and coolant in the radiator
- Hole in the Cooling System
Stuck in Traffic? Don’t Fret
If your dashboard temperature gauge begins to rise or a fault indicator lights up while stuck in stop-and-go traffic or on a steep incline on a hot day, don't panic. Instead, use the following steps to determine the exact nature of the problem:
- If it is obvious that the car is overheating, stop on the right side of the road, open the hood, and wait for it to cool. Remember not to open the radiator cap in these situations and if your engine has boiled wait for it to cool completely before adding water. If the radiator needs to be topped up when the vehicle is hot, always do so slowly in the park or neutral mode.
- Shut off the air conditioner and open windows at the first hint of overheating, to reduce the load on the engine. The engine will then be able to cool down easily.
- If the car continues to overheat, use the heater and blower to transfer heat from the engine to the passenger compartment. Be prepared to deal with a relatively high dose of heat here for a while.
- Shift to neutral or park and give the engine a slight boost if you get stuck in traffic with the temperature reading rising. This makes the water pump and fan run faster and draw more fluid and air through the cooler. The circuit supports the cooling process.
- Instead of climbing up again and again and then braking in braking and reversing traffic, crawl slowly, just above idle. The motor is more heavily loaded and overheated by the braking resistor. it gets high with the vehicle in front.
Disconnecting the Thermostat:
If the car still doesn't cool after following all the above, here's what to do: If the cooling system isn't leaking, a faulty thermostat may be the cause. In the meantime, if you can safely get to the thermostat after parking it on the side, it is very unlikely to malfunction. If the engine starts and runs normally without a thermostat, the old thermostat is likely causing problems.
Handling an Overheated Engine:
If the temperature gauge needle hits the creepy red area, or if the "Check Engine" or "Temperature" malfunction indicator on the dashboard flashes dark lights, the car is overheating. Low oil level, a defective ignition system, a collapse. A lower radiator hose or low coolant level can be the problem.
