How long will it take for the engine to seize after reaching 100°C water temperature?

After the engine water temperature reaches 100 degrees, driving for 1-2 kilometers may cause engine seizure. Here are specific details about engine seizure: 1. Cause: Engine seizure refers to the appearance of obvious longitudinal mechanical scratches and abrasions on the inner wall of the cylinder within the movement range of the piston rings, and in severe cases, adhesive wear occurs. 2. Prevention: The engine must be properly run-in, maintain the normal cooling water temperature between 70°C and 95°C, avoid engine overheating, do not operate under overload, do not start the engine without sufficient coolant, and strengthen the maintenance of the air filter to prevent dust from being sucked into the cylinder.
As a long-time driving enthusiast, I believe the time it takes for an engine to seize after reaching 100 degrees Celsius is not fixed—it really depends on the specific situation. If I see the temperature gauge hit 100, I immediately pull over because it can quickly rise to a dangerous level within minutes. Most modern cars will trigger an alarm or activate a protection system between 105 and 110 degrees, but if the cooling system fails—like a broken fan or coolant leak—the temperature can skyrocket, and the pistons may seize in just two to three minutes. This is especially true during hot summer days or high-speed driving when the engine is under heavy load and heat dissipation slows down, making problems escalate faster. I remember a friend who ignored a high engine temperature warning and ended up with a seized engine in less than 10 minutes, costing thousands in repairs. So, my advice is to shut off the engine immediately if the temperature warning light comes on, check the coolant and fan, and avoid risking further damage. Regular maintenance, like timely coolant replacement, can prevent minor issues from turning into major headaches.
