There is no worse time to breakdown than in the winter. When your car isn’t working like you expect it to it is always frustrating but add being cold to that and you’ve got a really bad day. Even if you’re a weekend mechanic working on a car with frozen fingers is never enjoyable. Worse yet if your car leaves you stranded, sitting in the cold hoping the tow truck shows up soon can feel like an eternity. That is why it is extremely important to make sure that your vehicle is running properly during the winter months.
Maybe as the summer and fall have gone on you’ve noticed small things wrong with your car. Things like lights not working or windows not shutting all the way. Maybe you’ve got a check engine light that has been on and you’re hoping it’s nothing. Or maybe you’ve got a temperature gauge that is wandering around and you’re hoping that as the weather gets colder your car will stop overheating.
The reality is that colder temperatures really won’t help your vehicle’s overheating problem and you will find yourself still asking, why is my car overheating? Your car may be overheating for a variety of reasons, so it’s best to try and understand where this extra heat comes from before we move onto a solution.
The engine in your vehicle can be classified as a heat engine, meaning it turns heat into mechanical work. The heat comes from the combustion process of fuel and air. This heat then causes the gases in your cylinder to expand rapidly pushing against the piston in your engine forcing it to the bottom of the cylinder. The crank shaft in your engine turns this motion of your piston into a rotational force which turns your transmission, axles, and consequently wheels.
Unfortunately the engine in your car cannot turn all of the heat produced by the combustion process into mechanical energy. This extra heat that cannot be used is called waste heat and is removed in a variety of ways. As the exhaust gases are pushed out of the chamber, they carry a significant amount of the waste heat with them. Also, as the cool intake air enters your engine it will absorb some of the waste heat as well, especially in the winter. For engines used in vehicles today, there is even more waste heat than can be removed through the exhaust gas and intake air so your vehicle’s cooling system is used to remove the rest of the waste heat.
If your vehicle is overheating it is because the waste heat created by the combustion process is not being entirely removed by these 3 methods so your engine heats up. It is possible that your engine’s combustion process is creating more heat than usual, but that is unlikely in today’s fuel injected vehicles with electronically controlled ignition timing.
It is also unlikely that much has changed in your vehicle’s intake air or exhaust gases’ ability to cool your engine unless you have a significantly clogged exhaust system, so most often the problem lies with your vehicles cooling system. Your vehicle’s cooling system is comprised of a few simple components. Your thermostat, radiator, water pump, engine coolant passages, heater core and the hoses connecting them all make up your vehicle’s cooling system. The only moving components are your water pump and the thermostat. If your thermostat sticks shut it can cause your vehicle to overheat. Also, if your water pump fails it won’t move the coolant through your engine causing it to overheat as well. These two components failing are unlikely due to normal wear but can break under extreme conditions.
The other components in your engine’s cooling system will fail due to rupturing or leaking. Most often, it turns out to be a leak that causes your engine to overheat. If enough coolant leaks out of your cooling system, then there isn’t enough coolant to remove all of your engine’s waste heat. Finding the source of your cooling leak can be a complicated process due to the location of the cooling system components and the fact that coolant doesn’t leave a residue like leaking oil does.
Sealing a cooling system leak is now a much simpler process with BlueDevil Heat Gasket Sealer. BlueDevil Head Gasket Sealer is designed to seal the cooling system leak in your vehicle, specifically those from your engine’s cooling passages sealed by your head gasket. BlueDevil Head Gasket Sealer is BlueDevil’s most powerful cooling system sealing product and can stop the leaks in your vehicle’s cooling system guaranteed!
