How Evans Can Help Your Car Keep Cool in Extreme Heat
Extreme heat can do serious damage to your car. With a heat wave driving temperatures into the 100s this summer, motorists need to take extra precautions to avoid boilovers, which can turn deadly when the internal temperature of your engine reaches a critical level. Not only do boilovers stop your engine (and the air conditioning), they can result in expensive repairs.
How Extreme Heat Causes Boilovers
Engine boilovers occur when traditional antifreeze, which is usually 50% water, reaches its boiling point and turns to vapor, blowing steam and liquid out your radiator cap and putting extreme pressure on your engine components.
Water boils at 212°F at sea level. Traditional coolants typically boil at around 226°F. But problems crop up well before those temps. Once your engine passes 230°F, the engine is actively overheating.
Solving the Overheating Problem
The problem with traditional coolants is that traditional ethylene glycol antifreeze is mixed with water in a 50-50 ratio. It’s the relatively low boiling point of water that causes the coolant to overheat.
So what’s the solution? Removing the water. Waterless coolant prevents boilovers because there’s no water to boil.
The boiling point of Evans waterless coolants is 375°F—far about the operating temperature of an engine. So when the temperature gauge starts to climb dangerously and water-based antifreezes start to boil, Evans remains in liquid form. That means even in extreme heat, Evans coolant is still doing its job, protecting and cooling your engine so it won’t boil over.
