When you use an engine heater, your engine's temperature is returned to ideal before it starts, which is 15-20 degrees Celsius (59-68 degrees Fahrenheit). Well, as its name suggests, the engine heater heats up the engine before you start it. And we all know how much it costs to repair an engine, that's something you want to avoid if possible.
This will result in severe wear on the engine components. This is a problem, as burning the fuel incompletely will produce a lot of harmful gases, polluting the environment.Īlso, because low temperatures will solidify the oil, it won't flow as fast and won't get between the crankshaft and the cylinder in time, failing to lubricate them. The effects of cold shrinkage can affect the gap between engine parts so much that they can break the engine block's airtightness, causing the fuel to burn incompletely in the engine cylinder. However, it is challenging to take into account the shrinking size if you have different types of metal involved, with different sizes. Of course, when the engine starts, it expands because of the heat created inside, which is also normal. This is nothing out of the ordinary, and engine designers take it into account when building their products. Depending on the engine size and the amount of metal used, the shrinkage size is different. And, as you know, metal shrinks at low temperatures. The result is that the starter fails to drive the piston and crankshaft to work, and your vehicle won't be able to start.įurthermore, the engine itself is made of metal, no matter which type of fuel it uses. Whether you have a diesel engine, a gasoline engine, or an engine that runs on natural gas, all those face similar issues when temperatures get low - the engine's lubricant will start to solidify. The #1 reason why you should consider using an engine heater is the natural behavior of fuel.
