High temperatures can cause lots of problems. As the summer approaches, we can all look forward to that overwhelming sensation of getting into a car that’s been sitting in the hot sun all day and you can’t even breath until you get the windows down. High temperatures are uncomfortable for us, but they can be even worse for our cars. With high ambient temperatures, your coolant temperature can rise quickly to dangerous levels causing engine damage.
The cooling system in your car is designed to keep things cool under even the most extreme conditions. Vehicle manufacturers know how dangerous it can be to allow your coolant temperature to rise so they do all they can to make sure engine temperatures stay where they need to be.
The water pump in your engine is designed to move water around the engine anytime the engine is running. When your engine is cold, the water just circulates around your engine and heater core to keep temperatures even and allow the engine to warm up quickly. Once the temperature hits a certain point, the thermostat will open allowing coolant to flow through the vehicle’s radiator maintaining a constant coolant temperature. Your radiator cap keeps the cooling system at a constant pressure so that even at high temperatures the coolant will not boil and lose its cooling ability.
All these components are designed together to keep a consistent temperature across your engine so that everything can function properly. If temperatures get too high it can cause a lot of problems.
One of the biggest problems with having a high coolant temperature while you’re driving is that your engine oil will not lubricate properly. The oil your car uses is designed to work in a specific environment. As it’s temperature rises its viscosity goes down, meaning it gets thinner. If your engine oil gets too thin, it will not be able to properly lubricate your engine bearings leading to accelerated wear. Even if your car doesn’t have an oil cooler, high coolant temperatures can quickly increase your engine oil temperatures and lead to poor lubrication.
The other dangers of having high coolant temperatures in your car have to do with the materials used in the construction of your engine. Engines today utilize a significant amount of electronics from sensors to small servo motors to control things and most of these components also do not respond well to high temperatures. Even if these components are mounted in your engine bay, a high coolant temperature can quickly lead to high engine bay temperatures which can cause erroneous readings and damage to these electrical components. Lastly, high temperatures can lead to damage of others components when they reach their thresholds. Plastic intake manifolds to high performance metals can all start to melt or deform at high temperatures causing cracks, leaks and failed seals and gaskets.
Even though your vehicle’s manufacturer designed the cooling system in your car to adequately remove waste heat, many factors can lower your vehicle’s cooling systems capacity or increase the amount of waste heat produced. Things like cooling system scale and radiator damage can lower your cooling systems ability to keep your engine cool and everything from extreme weather or driving conditions to performance modifications can increase the amount of waste heat produced by your vehicle’s engine.
There are drastic measures you can take to lower your coolant temperature like replacing your thermostat your radiator. Thermostats are designed to open at different temperatures so a thermostat that allows coolant to flow to the radiator at a lower temperature can help keep your engine running cooler. Also, adding a larger radiator can increase your cooling system’s capacity by allowing the engine coolant to remain in the radiator longer further cooling it before it returns to the engine. Both of these upgrades can provide lower coolant temperatures however they can be time consuming or expensive installation processes.
The quickest and easiest way to lower your coolant temperature is to simply add BlueDevil Engine Cool to your vehicle’s coolant. BlueDevil Engine Cool is compatible with all types of engine coolant and can reduce your coolant temperature by 25oF!!
