How Long Does It Take for an Engine to Overheat and Cause Cylinder Scoring When Driving in High Temperatures?
3 Answers
Driving just one or two kilometers in high temperatures can cause a car to stall or lead to cylinder scoring, and in severe cases, it may even result in engine failure. The methods to determine whether cylinder scoring has occurred and the corresponding solutions are as follows: Methods to Determine Cylinder Scoring: Under normal circumstances, the vehicle's power will significantly decrease, commonly referred to as the car lacking strength; abnormal water temperature, where the engine shows high temperature or even boils after running for a short while; increased exhaust emissions with blue smoke from the rear exhaust; and unusual engine noises that sound muffled and rough. Solutions for Engine Cylinder Scoring: If you encounter cylinder scoring while driving, gradually reduce speed without abruptly pressing the accelerator, maintaining a steady pace. Then, find a suitable place to stop the car, open the engine hood, and begin cooling it down.
I remember one summer when I was driving long-distance with the AC on, the temperature gauge suddenly shot up above the red line. I was so scared that I immediately pulled over to check the coolant level—sure enough, it was almost empty. In situations like this, if you continue driving with overheating, the engine can seize within minutes, especially in older cars with poor cooling systems. Last time, my friend's car seized after less than half an hour on a mountain road due to a clogged radiator. It's advisable to keep an eye on the temperature gauge regularly. If the temperature exceeds 90 degrees, you should be alert—stop to rest or add coolant. Don’t ignore these small issues, or you’ll end up with a hefty repair bill.
Driving in high temperatures does require caution, as the risk of engine overheating and cylinder scoring is significant. The duration really depends on the situation. Newer cars might last a bit longer thanks to their protection systems, but my old Jeep started making strange noises after about 15 minutes in the desert, nearly causing cylinder scoring. Key factors include high ambient temperatures, insufficient coolant, or fan malfunctions, all of which can accelerate overheating. For safety, I make it a habit to check the radiator and fan every month to ensure they're functioning properly. If the temperature warning light on the dashboard comes on while driving, don't hesitate—pull over immediately to let the engine cool down. Prevention is always better than repair.
